2026 – COMPLETE CONCEPT REVIEW &
PRACTICE MATERIALS (LATEST EDITION)
SECTION 1: FUNDAMENTALS OF FLIGHT (AERODYNAMICS)
1. Q: What are the four fundamental forces acting on an aircraft in flight?
A: Lift, Weight (Gravity), Thrust, and Drag.
2. Q: Define Angle of Attack (AOA).
A: The angle between the chord line of the wing and the relative wind (oncoming
airflow).
3. Q: What is Bernoulli’s Principle as it relates to lift?
A: Faster-moving fluid (air) has lower pressure. An airfoil is shaped so air moves faster
over the top, creating lower pressure above the wing and generating lift.
4. Q: What is Newton’s Third Law’s contribution to lift?
A: The wing deflects air downward (action), and the air pushes the wing upward
(reaction).
5. Q: What is ground effect?
A: Reduced induced drag near the ground (within one wingspan) due to interference of
wingtip vortices, increasing lift and efficiency.
6. Q: What are the three axes of an aircraft?
A: Longitudinal (roll), Lateral (pitch), and Vertical (yaw).
7. Q: What control surface primarily controls movement about the longitudinal axis?
A: Ailerons.
8. Q: What is the difference between static and dynamic stability?
A: Static stability is the initial tendency to return to equilibrium after a disturbance.
Dynamic stability describes how the aircraft oscillates over time after the disturbance.
9. Q: What is a stall?
A: A disruption of smooth airflow over the wing due to exceeding the critical angle of
attack, resulting in a loss of lift.
, 10. Q: What is Mach number?
A: The ratio of an object's speed to the speed of sound in the surrounding medium (e.g.,
Mach 1 = speed of sound).
SECTION 2: AIRCRAFT SYSTEMS & PROPULSION
11. Q: In a typical piston engine, what does the carburetor or fuel injection system do?
A: Mixes fuel with air in the proper proportion for combustion.
12. Q: What is the purpose of the turbocharger in an aircraft engine?
A: Compresses intake air to maintain sea-level power output at higher altitudes.
13. Q: Describe the basic operating principle of a gas turbine (jet) engine.
A: Intake, Compression, Combustion, and Exhaust (Brayton Cycle). Air is compressed,
mixed with fuel and ignited, and the expanding gases spin a turbine and provide thrust.
14. Q: What is the difference between a turbojet and a turbofan engine?
A: A turbojet generates thrust primarily from exhaust gases. A turbofan has a large fan at
the front that bypasses air around the core, providing more efficient thrust at subsonic
speeds.
15. Q: What is the function of an aircraft’s empennage?
A: The tail assembly (including stabilizers and control surfaces) that provides stability and
pitch/yaw control.
16. Q: What are the primary types of aircraft landing gear configurations?
A: Tricycle (nose wheel + two mains) and Conventional/Tailwheel (two mains + tail
wheel).
17. Q: What is the purpose of a pitot-static system?
A: It provides pressure readings to the airspeed indicator (pitot + static), altimeter, and
vertical speed indicator (static).
18. Q: What does the attitude indicator (artificial horizon) display?
A: The aircraft's orientation relative to the earth's horizon (pitch and bank).
19. Q: What is the primary function of a flap?
A: To increase wing camber and area, providing higher lift at lower speeds for takeoff
and landing.
20. Q: What does the term "fly-by-wire" (FBW) mean?
A: A system where manual controls are replaced with electronic interfaces; flight control
computers process pilot inputs and command actuators.
,SECTION 3: AEROSPACE HISTORY & MILESTONES
21. Q: Who are the Wright Brothers and what was their key achievement?
A: Orville and Wilbur Wright; achieved the first sustained, controlled, powered heavier-
than-air flight on December 17, 1903, at Kitty Hawk.
22. Q: What was Charles Lindbergh’s famous feat?
A: First solo, nonstop transatlantic flight from New York to Paris in the Spirit of St.
Louis (1927).
23. Q: Who was the first human in space?
A: Yuri Gagarin (USSR), on Vostok 1, April 12, 1961.
24. Q: What was the mission of Apollo 11?
A: The first manned lunar landing. Neil Armstrong and Buzz Aldrin walked on the Moon
on July 20, 1969.
25. Q: What was the Space Shuttle?
A: NASA's partially reusable orbital spacecraft system, used from 1981 to 2011.
26. Q: What was significant about the Voyager spacecraft?
A: Two probes (Voyager 1 & 2) launched in 1977 that conducted grand tours of the outer
planets and are now in interstellar space.
27. Q: Who was the first American woman in space?
A: Dr. Sally Ride, aboard Space Shuttle Challenger (STS-7) in 1983.
28. Q: What was the "X-1" and who famously piloted it?
A: The Bell X-1 was the first aircraft to break the sound barrier in level flight, piloted by
Captain Chuck Yeager (1947).
29. Q: What was the "Mercury Seven"?
A: The first group of NASA astronauts selected in 1959 (e.g., Shepard, Grissom, Glenn).
30. Q: What is Sputnik and why was it significant?
A: The world's first artificial satellite, launched by the USSR in 1957, starting the Space
Age and the "Space Race."
SECTION 4: SPACE SCIENCE & ORBITAL MECHANICS
31. Q: What is Newton’s Law of Universal Gravitation?
A: Every mass attracts every other mass with a force proportional to the product of their
masses and inversely proportional to the square of the distance between them.
, 32. Q: What is an orbit?
A: A stable path of one celestial body around another, where the centripetal force is
provided by gravity.
33. Q: What is escape velocity?
A: The minimum speed needed for an object to break free from a planet's gravitational
pull without further propulsion.
34. Q: What is a geostationary orbit (GEO)?
A: An orbit at ~35,786 km above Earth’s equator, where a satellite's orbital period
matches Earth's rotation, making it appear stationary.
35. Q: What is a low Earth orbit (LEO)?
A: An orbit relatively close to Earth (approx. 160 to 2,000 km), used by the ISS, Hubble,
and many satellites.
36. Q: What are the three stages of a typical rocket’s ascent to orbit?
A: 1) Launch/Powered Ascent, 2) Staging/Separation, 3) Orbital Insertion.
37. Q: What is the Van Allen Radiation Belt?
A: Zones of charged particles trapped by Earth's magnetic field, posing a radiation hazard
to spacecraft.
38. Q: What is microgravity?
A: The condition where the effect of gravity is greatly reduced, creating a near-
weightless environment (often incorrectly called "zero-g").
39. Q: What is the Kármán Line?
A: The internationally recognized boundary of space, at 100 km (62 miles) above sea
level.
40. Q: What is the difference between a prograde and a retrograde orbit?
A: Prograde orbits move in the same direction as the planet's rotation (eastward).
Retrograde orbits move opposite (westward).
SECTION 5: ROCKETRY & PROPULSION
41. Q: State Newton’s Third Law of Motion in the context of rocketry.
A: For every action, there is an equal and opposite reaction. Rocket exhaust (action)
pushes the rocket forward (reaction).
42. Q: What is specific impulse (Isp)?
A: A measure of rocket engine efficiency, equivalent to thrust produced per unit of
propellant consumed over time. Higher Isp = more efficient.
