- What is load factor in aircraft flight?
Show answer
The ratio of the total aerodynamic force to the aircraft's weight.- How does load factor affect stall speed?
Show answer
Stall speed increases as the square root of load factor. Stall speed at 2 g equals 1.41 times clean stall speed.- Define service ceiling.
Show answer
The altitude at which an aircraft can climb at a rate of 100 feet per minute.- Define absolute ceiling.
Show answer
The maximum altitude at which an aircraft cannot climb any further, where the rate of climb is zero.- What is the primary advantage of turbocharging an aircraft engine?
Show answer
It maintains engine power at higher altitudes by compressing the thinner air entering the engine.- What is propeller pitch?
Show answer
The theoretical distance a propeller would travel forward in one complete revolution if it moved through a solid.- How does a constant speed propeller maintain optimal efficiency?
Show answer
It automatically adjusts blade angle to maintain selected RPM as airspeed and altitude change.- What is ground effect?
Show answer
A reduction in induced drag when an aircraft operates within one wingspan height of the surface.- Why is induced drag greatest at low airspeeds?
Show answer
At low speeds, a larger angle of attack is required to maintain lift, creating stronger tip vortices and more induced drag.- Name the primary sources of parasitic drag.
Show answer
Form drag from the fuselage and interference drag where different aircraft components meet.- Why is weight and balance critical for commercial aircraft operations?
Show answer
It affects center of gravity, which determines aircraft stability, handling, and performance characteristics.- How does a forward center of gravity affect aircraft performance?
Show answer
It increases lift requirements, reduces stall margin, requires more elevator authority, and increases drag.- Define density altitude.
Show answer
The altitude at which the atmosphere has the same density as the actual altitude, corrected for temperature and pressure.- What performance degradation occurs at high density altitude?
Show answer
Takeoff distance increases, rate of climb decreases, and true airspeed is higher than indicated airspeed.- What is a temperature inversion?
Show answer
An atmospheric condition where temperature increases with altitude instead of the normal decrease.
