Fighter Pilot Lecture Notes

Course Introduction

  • Instructor: Laz (nickname due to fighter pilot culture)
  • Course: Ground school for aviation
  • Commended the opportunity and instructors (Tina and Phil)

Call Signs in Fighter Pilots

  • Call signs are often silly, not glamorous like in movies (e.g., Top Gun is cited as unrealistic).

Personal Background

  • Laz is a test pilot, engineer, and has experience with various aircraft.
  • Graduated from MIT in 2018, completed combat tours.
  • Passion for flying, especially in challenging situations.

F-22 Flight Control Overview

  • Learning about F-22 and its relevance to general aviation (e.g., Cessna).
  • Basic principles learned in ground school are applicable to advanced fighter aircraft.
  • Key message: NO difference in foundational principles between small planes and advanced fighters.

Test Pilot Role

  • Test pilots work with new technology, weapons, and aircraft.
  • Experience in flying 76 different types of airplanes, emphasizing versatility.
  • Importance of discernment when evaluating flight characteristics of different aircraft.

Flight Control Mechanics

  • Discussion about aircraft design: Why do Cessnas and Raptors look the way they do?
    • Wing Positioning: High-wing for Cessna vs. Mid-wing for Raptor for different visibility and comfort.
    • Swept Wings: To manage airflow and reduce drag at high speeds (important near Mach).
  • Stealth and payload considerations:
    • Raptor designed to deflect radar signals with no right angles for stealth capabilities.
    • Raptor uses advanced materials (e.g., titanium) for weight efficiency.

Aerodynamics and Performance

  • Raptor can remain stable and maneuverable at a wide range of speeds (from Cessna's slow speed to over twice the speed of sound).
  • Can fly up to 65,000 feet, with significant energy management in flight control systems.

Flight Control Systems

  • The Raptor operates with reversible flight control systems (linked to stick movement).
  • At high speeds, control surfaces are hydraulically operated (high PSI systems).
  • Electrical systems power flight controls; tension on control surfaces gives feedback to pilot about maneuverability.
  • Permanent Magnetic Generators are crucial for generating energy for flight control systems.
  • Redundancy in electrical systems for safety and reliability.

Key Flight Control Features

  • Raptor uses advanced leading-edge flaps, ailerons, and rudders for various situations.
  • Controls are designed to provide responsive and sensitive feedback to pilots.
  • High-performance capabilities allow the aircraft to execute complex maneuvers easily.

Handling Aerodynamic Challenges

  • During specific tactical roles and maneuvers, the flight control system autonomously adjusts for optimal performance.
  • Takeoff and Landing: Adjustable flaps and ailerons contribute to a shorter runway need at takeoff and maximum traction during landing.

Digital Cockpit Innovations

  • Raptor includes a modernized cockpit with digital interfaces for better pilot visibility and efficiency.
  • Importance of hands-on throttle and stick (HOTAS) systems to control flight without distraction.
  • Digital flight control systems allow for heavy automation which relieves pilot workload.

Pilot Experience Considerations

  • Some tasks are simplified for pilots using automation (e.g., engine problems auto-managed by the aircraft).
  • Future of aviation may involve unmanned systems, but human input is vital for complex, rapidly changing combat scenarios.

Implications of Automation

  • Transitioning roles where pilots engage more in strategic decisions rather than navigation and control.
  • Constant evolution required to integrate new technologies into existing flight systems.

Conclusion and Discussion

  • Lecture encouraged participation and exploration of topics on aircraft design, automation, and pilot roles.
  • Engaged students through thought exercises, practical questions, and interactive demonstrations.

Next Steps

  • Video demonstrations of Raptor capabilities related to flight controls and maneuvers.
