Part 107 Drone Study Guide

Dec 2, 2025

Overview

This lecture is a Part 107 (FAA drone license) study guide covering rules, airspace, charts, airport operations, weather, and sample exam questions.

Part 107 Basics

  • Part 107 is 14 CFR Part 107 in the FAR/AIM, governing small unmanned aircraft systems (sUAS) / drones.
  • It applies to civil drone operations in the National Airspace System (NAS).
  • You do not need to buy the FAR/AIM book for the test, but it contains all Part 107 rules.

Commercial vs Recreational Use

  • Recreational = flying only for fun.
  • Commercial = any operation for compensation or hire, including:
    • Direct payment for services.
    • Barter (e.g., tickets, discounts, goods in exchange for flying).
    • Selling photos or videos later, even if originally shot recreationally.
  • Any commercial operation requires a Part 107 remote pilot certificate.

Registration Requirements

  • All drones (recreational or commercial) must be registered if:
    • Pilot is 13 or older.
    • Pilot is a U.S. citizen or legal resident.
    • Drone weighs between 0.55 lb (250 g) and 55 lb.
  • Registration gives you a unique number that must be visible on the outside of the drone.

Drones Under 0.55 lb (250 g)

  • No FAA registration required if drone is under 0.55 lb.
  • If used commercially, you still must hold a Part 107 certificate.

Remote ID

  • Remote ID is an electronic “license plate” broadcasting:
    • Drone position, altitude, and ID.
    • Pilot / control station location.
  • Many newer drones have built‑in Remote ID compliance.
  • Older drones may need an external Remote ID module registered with the FAA.

Part 107 Exam Details

  • Taken at an FAA-approved testing center (not at home).
  • 60 multiple-choice questions.
  • Time limit: 2 hours.
  • Passing score: 70% or higher.
  • If you fail, you may retake after 14 days.

Eligibility for Exam

  • At least 16 years old.
  • Able to read, speak, write, and understand English.
  • Physically and mentally able to safely operate a small UAS.

After Passing the Exam

  • Complete online forms; FAA mails your remote pilot certificate.
  • Recurrent training is required every 24 calendar months:
    • Done online, at home, free.
    • After initial pass, you do not retake the in-person exam.

Remote Pilot in Command (PIC) and Crew Roles

  • Remote Pilot in Command (PIC):
    • Person responsible for the flight and compliance with Part 107.
    • Must hold a remote pilot certificate if conducting Part 107 operations.
    • Responsible for damage or injury caused by the drone.
    • May transfer controls to another licensed pilot during flight, but retains responsibility.

Other Crew Roles

  • Visual Observer (VO):

    • Helps maintain visual line of sight (VLOS) of the drone.
    • Warns PIC about proximity to people, obstacles, other aircraft.
    • Multiple visual observers may be used.
  • Person Manipulating the Controls:

    • Licensed pilot who physically flies the drone.
    • PIC may be different from the person on the sticks but is still responsible.
  • Control Station:

    • Where the pilot operates the drone.
    • Includes the controller(s) used to fly and control camera/gimbal.

Operating Rules and Limitations

Weight and Speed Limits

  • “Small UAS”: total takeoff weight (drone + payload) must be:
    • At least 0.55 lb (250 g) and less than 55 lb for normal Part 107 operations.
  • Drones over 55 lb require:
    • Exemption or Special Airworthiness Certificate from FAA.
  • Maximum groundspeed under Part 107: 100 mph.

Standard Altitude Limit

  • Maximum altitude: 400 ft AGL (Above Ground Level).
  • AGL: altitude measured from the ground surface.
  • MSL (Mean Sea Level): altitude measured from sea level (true altitude).
  • Exam questions may use either AGL or MSL; read carefully.

Visibility and Cloud Clearance

  • Minimum flight visibility: 3 statute miles.
  • Cloud clearance:
    • At least 500 ft below clouds.
    • At least 2,000 ft horizontally from clouds.
  • Cannot take off if you cannot maintain VLOS due to fog, etc.

Flying Near Tall Structures

  • You may fly higher than 400 ft AGL when:
    • Within 400 ft of a tall structure (e.g., tower, building) in controlled or uncontrolled airspace where you are allowed to fly.
    • Up to 400 ft above the structure’s top.
    • Example: Tower 1,200 ft tall → legal up to 1,600 ft AGL when within 400 ft horizontally.

Right-of-Way

  • Manned aircraft always have right-of-way over drones.
    • Includes airplanes, helicopters, gliders, etc.
  • PIC must yield by maneuvering (e.g., descend below treeline) to avoid conflicts.

In-Flight Emergencies and Deviations

  • Emergencies: collision risks, battery fires, loss of control, etc.
  • Primary action: maintain or regain control of the drone while assessing situation.
  • If on collision course with manned aircraft, you may deviate from Part 107 rules as necessary to avoid collision.
  • If the FAA contacts you, you may need to submit a written report of the deviation.

Battery Safety

  • Drone batteries (often lithium-ion) are highly flammable.
  • Before use:
    • Inspect for damage or swelling.
  • After flight:
    • Allow battery to cool fully before recharging.
  • Disposal:
    • Do not throw in normal trash.
    • Use proper battery disposal facilities (e.g., specialized stores).

Accident Reporting to FAA

  • You must report to the FAA if:
    • Drone operation causes serious injury or unconsciousness, or
    • Causes property or other damage estimated at $500 or more (excluding your own drone).
  • Example: Person hit, medical bills > $500 → must report.

Flying Over People

You generally may not fly over people unless one of these is true:

  • People are directly involved in the operation.
  • People are under a covered structure or inside a stationary vehicle that can protect them.
  • Operation meets requirements of at least one of the four “categories” for operations over people.

Categories for Operations Over People (original rule set)

  • Category 1:

    • Drone weighs less than 0.55 lb.
    • Rotating parts (propellers) must not cause lacerations (e.g., prop guards).
    • Must have Remote ID.
    • No prolonged hovering directly over people.
  • Category 2:

    • Drone weighs more than 0.55 lb.
    • No airworthiness certificate required.
    • Kinetic energy on impact ≤ 11 ft‑lb.
    • Must meet FAA “means of compliance” and be listed on a Declaration of Compliance.
  • Category 3:

    • Similar to Category 2, but kinetic energy ≤ 25 ft‑lb.
    • Also requires FAA compliance documentation and Declaration of Compliance.
  • Category 4:

    • Drone weighs more than 0.55 lb.
    • Must have an Airworthiness Certificate.
    • Operated under FAA‑approved flight manual and operating limitations.

Updated Operational Path (waiver-based)

  • Submit a waiver request via FAA DroneZone (well in advance).
  • After approval, requirements include:
    • Visual Observer present.
    • Prop guards installed.
    • Anti‑collision lights installed.
    • Remote ID.
    • If drone weighs more than 399 g (≈0.88 lb), an ASTM parachute system is required (subject to availability).

Operations from Moving Vehicles and Boats

  • Allowed to operate from moving land/water vehicles if:
    • Area is sparsely populated (few or no people).
    • VLOS is maintained (with VOs if needed).
    • Crew communicates continuously.
    • Person flying the drone is a passenger (not the driver).
  • Not allowed to operate from an actual aircraft.

Payloads and Deliveries

  • No reckless operations or hazardous dropping of objects.
  • Do not overload the drone beyond manufacturer limits.
  • Cargo delivery allowed if:
    • Total weight (drone + cargo) < 55 lb.
    • Operation stays within a single state.
    • No hazardous manner of dropping cargo.
    • VLOS is maintained.

Address Changes

  • If you move, you must notify FAA of address change within 30 days.
  • Failure to do so can disqualify your certificate.

Alcohol and Drugs

  • No flying within 8 hours of consuming alcohol (“bottle to throttle” = 8 hours).
  • Blood Alcohol Concentration (BAC) must be < 0.04%.
  • No drugs that impair performance.
  • Refusing testing can lead to suspension or revocation of your certificate (up to one year or more).

Crew Resource Management (CRM) and Human Factors

  • CRM: using all resources (people, equipment, information) to operate safely.
  • All crew must be physically and mentally fit.
  • Replace any crew member showing impairment or unfitness.

Physical Risk Factors

  • Hyperventilation:
    • Fast, heavy breathing, reduces CO₂ in body.
    • Historically treated with “paper bag” breathing.
  • Fatigue:
    • Lack of sleep, reduces alertness and decision-making.
  • Alcohol/drugs:
    • Already covered; disqualifying.

Personality Risk Factors

  • Impulsivity:

    • Acts quickly without planning.
    • Solution: slow down, plan carefully.
  • Invulnerability:

    • Believes “nothing bad will happen to me.”
    • Increases risk-taking and unsafe behavior.
  • Macho:

    • Wants to “prove” skills, overconfident.
    • May ignore limits and procedures.
  • Anti‑Authority:

    • Dislikes rules, wants to ignore regulations.
    • Unsafe in regulated environments like airspace.
  • Resignation:

    • “Whatever happens, happens” attitude.
    • Fails to act to prevent or correct problems.
  • If any of these appear in you or crew:

    • Remove or replace that person before the operation.

Airspace Basics

Controlled vs Uncontrolled

  • Controlled Airspace:

    • Requires ATC authorization for Part 107 operations.
    • Includes Classes A, B, C, D, and E (in most contexts).
  • Uncontrolled Airspace:

    • Class G only.
    • No ATC clearance required for Part 107, but all other Part 107 rules still apply.

Airspace Classes Summary

ClassNameTypical Vertical LimitsNotes / Use
AAlpha18,000 ft MSL to 60,000 ft MSLHigh‑altitude IFR; not on sectional charts.
BBravoFrom surface or lower limits up to designated altitudeSurrounds busiest airports; “upside‑down wedding cake.”
CCharlieInner core SFC–4,000 ft AGL; outer core 1,200–4,000 ft AGLMedium‑busy airports; 10 nm core, 20 nm area.
DDeltaSFC up to 2,500 ft AGL (typical)Towered airports with less traffic.
EEchoVarious: SFC, 700 ft, 1,200 ft; 14,500–17,999 ft MSLControlled airspace between other classes.
GGolfSurface up to base of Class E (often 700 or 1,200 ft)Only uncontrolled airspace.

Class B (Bravo)

  • Surrounds very busy airports (e.g., ATL, LAX).
  • Appears as solid blue lines on sectional charts.
  • Side view resembles an upside‑down wedding cake with shelves.
  • Altitude labels: stacked “fraction-style” numbers:
    • Top number = ceiling (MSL) with two zeros added.
    • Bottom number = floor (MSL) with two zeros added.
    • Example: 100/30 → 10,000 ft MSL to 3,000 ft MSL.

Class C (Charlie)

  • Surrounds moderately busy airports.
  • On sectional: two solid magenta circles.
  • Structure:
    • Inner core: SFC to 4,000 ft AGL; radius 5 nm.
    • Outer core: 1,200 ft AGL to 4,000 ft AGL; radius 10 nm.
    • Outer area: up to 20 nm radius with radar service.
  • Typical test nuance: “typical Class C radius” is 20 nm (including outer area).

Class D (Delta)

  • Surrounds smaller towered airports.
  • Vertical limits: SFC to 2,500 ft AGL (commonly).
  • Radius: typically 4 nm.
  • On sectional:
    • Blue dashed circle.
    • Bracketed number shows ceiling (MSL) with two zeros added.
    • Example: [35] → ceiling 3,500 ft MSL.

Class E (Echo)

  • Starts at:
    • SFC (for some airports with dashed magenta line).
    • 700 ft AGL (shaded magenta band).
    • 1,200 ft AGL (shaded blue or general background).
  • Also exists from 14,500 to 17,999 ft MSL over large regions.
  • Fills “gaps” between other controlled airspace.

Class G (Golf)

  • Uncontrolled airspace.
  • From the surface up to the overlying controlled airspace base (often 700 or 1,200 ft AGL).
  • In some remote areas (e.g., parts of Alaska) extends up to 14,500 ft MSL.

ATC Authorization in Controlled Airspace

  • For Part 107 in Classes B, C, D, or E (at surface):
    • Must obtain ATC authorization (e.g., via LAANC or DroneZone).
  • Many exam questions simply ask:
    • “What is required to operate in Class B/C airspace?” → ATC authorization.

Special Use and Other Airspace

Prohibited Areas

  • Established for national security (e.g., around the White House).
  • Usually active 24/7; no operations allowed without very specific authorization.
  • Shown on sectional with special boundaries (not deeply detailed here, but clearly marked).

Restricted Areas

  • Hazards such as artillery, missiles, or other dangerous activities.
  • May be active at certain hours; schedules listed in chart legend or publications.
  • You may only enter when:
    • Area is not active, or
    • You have permission from the controlling agency.

Warning Areas

  • Similar to restricted areas but located in international airspace.
  • Warn of potential hazards but do not strictly prohibit operations.
  • Check status before entering.

Alert Areas

  • High volume of training or unusual aerial activity (e.g., many helicopters).
  • Pilots may operate there, but must exercise extreme caution.
  • Example: Drone pilot had to drop to low altitude to avoid helicopters.

Military Operations Areas (MOA)

  • Separate military training from IFR traffic.
  • Operations allowed, but pilot should exercise caution.
  • You may obtain traffic advisories from the controlling agency.

Military Training Routes (MTR)

  • Depicted as light gray/blue lines labeled with IR or VR plus numbers.
    • IR = IFR training.
    • VR = VFR training.
  • Numbering:
    • Four digits: training route at or below 1,500 ft AGL.
    • Three digits: routes above 1,500 ft AGL (but may descend).
  • Hazard: high-speed military aircraft at low altitude.

Temporary Flight Restrictions (TFRs)

  • Temporary “no-fly” (or limited) areas for:
    • Major sporting events.
    • Disaster areas.
    • VIP movement (e.g., President).
  • Flying a drone in an active TFR can result in serious penalties.
  • You must wait until the TFR expires to operate.

National Parks and Protected Areas

  • Flying drones in National Parks is prohibited (recreational or commercial).
  • Penalties up to $5,000 and/or 6 months in jail.
  • Special use permits may be possible in rare approved cases.
  • On sectional, some protected areas appear as blue boundary lines with blue dots.

Sectional Chart Basics and Airport Information

Airport Colors

  • Blue airports:
    • Have a control tower (underlying B/C/D/E).
  • Magenta airports:
    • No control tower.

Sample Airport Information (Sectional Legend)

Using “Waco Regional” as example:

  • Airport name: “Waco Rgnl”.
  • Identifier: “ACT” (full ICAO often KACT).
  • CT 119.3:
    • Control Tower frequency 119.3 MHz.
  • Star symbol:
    • Indicates part-time tower hours (check Chart Supplement).
  • “C” in circle:
    • CTAF frequency is same as tower frequency when tower closed.
  • ATIS / AWOS / ASOS frequencies:
    • For automated weather broadcasts (e.g., ATIS 123.85).
  • Elevation (e.g., 516):
    • Airport elevation in feet MSL.
  • “L *”:
    • Part-time runway lighting.
  • Runway length (e.g., 71):
    • Longest runway in hundreds of feet (e.g., 7,100 ft).
  • UNICOM frequency:
    • Used to contact the FBO or ground services, not ATC.

Common Sectional Questions

  • Blue vs magenta:
    • Blue = towered; magenta = non-towered.
  • Restricted area operations:
    • Allowed only with authorization or when inactive.
  • MTR hazard:
    • Low-level, high-speed military jets → hazard to sUAS.

Coordinates, Latitude, and Longitude

  • Latitude:
    • Horizontal lines (east–west).
    • 0° at equator, up to 90°N / 90°S.
  • Longitude:
    • Vertical lines (north–south).
    • 0° at Prime Meridian (Greenwich, England).
  • Each degree = 60 minutes.
  • On sectional:
    • Degrees labeled; tick marks indicate minutes (longer ticks often every 10 minutes).
  • Example coordinate reading:
    • 47° 9′ N, 94° 38′ W:
      • Find 47° latitude, count ticks to 9 minutes.
      • Find 94° 38′ longitude similarly.
      • Identify the nearest airport at that intersection.

Airport Operations and Traffic Patterns

Why Drone Pilots Need Airport Knowledge

  • Drone operations near or on airports require:
    • ATC/airport permission.
    • Often a NOTAM (Notice to Airmen) is issued.
  • You must understand where aircraft will be to avoid conflicts.

Standard Traffic Pattern

  • Legs of the pattern (assuming left-hand pattern):
LegDescription
DepartureStraight out after takeoff along runway heading.
Crosswind90° turn from departure, crossing runway centerline.
DownwindParallel to runway in opposite direction of landing.
Base90° turn from downwind toward final.
FinalAligned with runway for landing.
UpwindOpposite of downwind; used often for go-arounds.
  • Aircraft usually enter pattern mid‑downwind at 45°.
  • Patterns can be:
    • Standard left‑hand turns.
    • Right‑hand (nonstandard) if indicated.
  • Pattern altitude often around 1,000 ft AGL (varies by airport).

Runway Headings and Numbers

  • Runway numbers = magnetic heading rounded to nearest 10°, then divided by 10.
  • Examples:
    • Heading 220° → Runway 22.
    • Opposite end is 040° → Runway 04.
  • A runway labeled “9” (090°) faces east.
    • Aircraft “short final for Runway 9” is approaching from the west.
  • Parallel runways:
    • Designated Left (L), Center (C), Right (R) (e.g., 09L, 09R).

Ground Areas: Movement vs Non-Movement

  • Non-movement areas:
    • Ramps, aprons, etc.
    • No tower clearance required to move.
  • Movement areas:
    • Taxiways and runways.
    • Tower clearance required (at towered airports).
  • Boundary marking:
    • Solid yellow line + dashed yellow line.
    • If solid line on your side → you are in non-movement area and must get clearance to cross.
    • If dashed line on your side → you are leaving movement area.

Taxiways and Runway Markings

  • Taxiways:
    • Yellow centerline; may have edge lines.
  • Runways:
    • All runway markings are white.
    • Hold short markings:
      • Two solid and two dashed yellow lines at runway/taxiway intersections.
      • If solid lines are nearest you → hold short; need clearance.
      • If dashed lines nearest you → exiting runway; no clearance needed to cross.

Airport Sign Types

TypeAppearancePurpose
MandatoryRed background, white textRequire clearance (e.g., runway entrance).
LocationBlack background, yellow text/borderShow current taxiway/runway or boundary.
Distance RemainingBlack, white numbersShow thousands of feet of runway remaining.
BoundaryYellow background, black symbolsSupport runway/taxiway boundary understanding.
DirectionYellow background, black arrows/lettersPoint to other taxiways/runways.
DestinationYellow background, black text/arrowsLead to ramps, terminals, runways, etc.
InformationYellow background, black textProvide general info (e.g., monitor frequency).

Monitoring CTAF/Radio

  • In or near airports, you should monitor traffic on CTAF or tower frequency.
  • A handheld aviation radio can be used to listen only.
  • Do not transmit unless explicitly coordinated or instructed.
  • Often, an airport official will be assigned to you and handle communications.

Weather Fundamentals for sUAS

Sun as Weather Source

  • Unequal heating of Earth’s surface:
    • Drives winds and pressure systems.
    • Creates updrafts (over hot surfaces like pavement, sand).
    • Creates downdrafts (over cooler surfaces like forests, vegetation).

Wind and Turbulence

  • Wind flow disturbed by terrain/buildings leads to updrafts/downdrafts.
  • Can cause turbulence affecting drone stability.

Air Masses

  • Large bodies of air with uniform temperature and moisture over large areas.
  • Form when air stays over a region long enough to take on its characteristics.
  • Types (maritime, continental, tropical, polar, etc.) exist, but the exam mainly wants the concept.

Fronts and Pressure

  • Front = boundary between two different air masses.
  • High pressure = ridge; low pressure = trough; fronts lie in troughs.
  • Cold front (blue line):
    • Leading edge of advancing cold air.
    • Moves quickly.
    • Often followed by windier, turbulent conditions.
    • Can create thunderstorms, hail, tornadoes.
  • Warm front (red line):
    • Leading edge of advancing warm air.
    • Moves slower; may produce long-lasting poor conditions:
      • Lower clouds, steady precipitation, lower visibility.

Stable vs Unstable Atmosphere

  • Atmospheric stability = resistance to vertical motion.
AtmosphereCharacteristics
StableSmooth air, fair–poor visibility, continuous precipitation.
UnstableTurbulent, good visibility between clouds, showery precipitation, potential storms.
  • Best flying conditions: cool, dry, stable air.

Clouds, Visibility, and Fog

  • Minimum conditions under Part 107:
    • ≥ 3 SM visibility.
    • Cloud clearance: 500 ft below, 2,000 ft horizontal.
  • Fog:
    • Essentially a cloud resting on the surface.
    • Forms at dew point temperature.

Types of Fog

  • Radiation (ground) fog:
    • Forms overnight when ground cools by radiation.
  • Advection (sea) fog:
    • Warm, moist air moves over a colder surface (e.g., ocean).
  • Upslope fog:
    • Moist air forced up terrain, cooling to dew point.
  • Precipitation‑induced fog:
    • Warm rain falls into cooler air; evaporation saturates air.
  • Steam fog:
    • Cold air moves over warmer water; evaporated moisture condenses.

Density Altitude

  • Definition: pressure altitude corrected for non-standard temperature.
  • Practical meaning: “altitude the aircraft feels like it is flying at.”
  • High density altitude (bad performance) caused by:
    • High temperature.
    • High humidity.
    • High elevation.
  • Higher density altitude = poorer aircraft and drone performance.

Thunderstorms

  • Very dangerous; avoid by at least 20 nm.
  • Three stages:
StageCharacteristics
CumulusStrong updrafts, building clouds; little/no rain reaches ground.
MatureBoth updrafts and downdrafts; heavy rain, hail, turbulence, strongest stage.
DissipatingMainly downdrafts; anvil-shaped cloud tops, storm weakens.
  • Lightning and thunder:
    • Rule of thumb: each second between flash and thunder ≈ 1 mile away.
    • Any thunder or lightning = do not operate drones; seek shelter.
  • Hail:
    • Caused by repeated lifting and dropping of water in updrafts/downdrafts, freezing and melting cycles.
  • Microbursts:
    • Small, intense downdrafts spreading outward near ground.
    • Extremely dangerous to aircraft; difficult to detect visually.
    • Example accident: Delta Flight 191 crash due to microburst.

METARs (Aviation Weather Reports)

  • METAR = Meteorological Aerodrome Report (current observation).
  • Standard global code; updated at least hourly or when conditions change.

Sample METAR Breakdown

Example (conceptual, not exact text formatting):

  • METAR:
    • Report type (could be SPECI if special).
  • KTPA:
    • Station (Tampa International).
  • 111320Z:
    • Date/time: 11th day, 13:20 Zulu.
  • AUTO:
    • Automated report (COR would indicate corrected).

      • RAB24: rain began 24 minutes past the hour.
      • SLP134: sea-level pressure 1013.4 hPa (encoded).

Common Weather Codes (Selection)

  • RA: rain.
  • SN: snow.
  • TS: thunderstorm.
  • SH: showers.
  • FG: fog.
  • BR: mist.
    • (minus): light.
    • (plus): heavy.
  • SCT: scattered clouds.
  • BKN: broken clouds.
  • OVC: overcast.

Wind Information Note

  • In METARs, wind directions are given in degrees true or referenced to the reporting station (exam expects “true” for weather).
  • Magnetic headings are used for navigation (runways, courses).

TAFs (Terminal Aerodrome Forecasts)

  • TAF = Terminal Aerodrome Forecast.
  • Forecast, not observation.
  • Usually valid for 24–30 hours.
  • Covers airspace within 5 SM of the airport.

Sample TAF Structure

Example pieces:

  • TAF KATL:
    • Forecast for Atlanta (KATL).
  • 162330Z:
    • Issued 16th day at 23:30 Zulu.
  • 1723/1806:
    • Valid from 17th at 23:00 Zulu to 18th at 06:00 Zulu.
  • 17009KT P6SM BKN250:
    • Winds 170° at 9 knots.
    • Visibility >6 SM (P6SM).
    • Broken clouds at 25,000 ft.
  • FM170300:
    • From 17th at 03:00 Zulu, conditions change to:
    • 09006KT P6SM BKN250 etc.
  • VC SH / VCSH:
    • Showers in the vicinity.
  • -SHRA:
    • Light rain showers.
  • BKN050:
    • Broken clouds at 5,000 ft.

Reading the Bottom Line Example

  • FM180200 26005KT P6SM VCSH OVC070:
    • From 18th at 02:00 Zulu:
      • Winds 260° at 5 knots.
      • Visibility >6 SM.
      • Showers in the vicinity.
      • Overcast at 7,000 ft.

Example Exam-Style Concepts

  • METAR wind question:
    • If wind section is “18004KT” → winds from 180° (south) at 4 knots.
  • Visibility in TAF section:
    • “3SM” = 3 statute miles; “P6SM” = greater than 6 statute miles.
  • When they say “direction and velocity at JFK”:
    • Find the METAR labeled KJFK, locate the “dddffKT” segment, decode.

Action Items / Next Steps

  • Review all Part 107 rules, especially:
    • Altitudes, visibility, cloud clearance, right-of-way, operations over people.
  • Practice reading:
    • Sectional charts (airspace, special use areas, airports, MTRs).
    • METARs and TAFs.
  • Memorize:
    • Airspace classes and markings.
    • Key distance/altitude numbers (400 ft, 3 SM, 500/2,000 cloud clearance).
  • Take multiple practice exams focusing on:
    • Airspace questions.
    • Weather interpretation.
    • Crew/human factors scenarios.
  • Register for the official exam at an FAA-approved testing center once confident in these topics.
