- What is load factor in aircraft flight?
- The ratio of the total aerodynamic force to the aircraft's weight.
- How does load factor affect stall speed?
- 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.
- The altitude at which an aircraft can climb at a rate of 100 feet per minute.
- Define absolute ceiling.
- 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?
- It maintains engine power at higher altitudes by compressing the thinner air entering the engine.
- What is propeller pitch?
- 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?
- It automatically adjusts blade angle to maintain selected RPM as airspeed and altitude change.
- What is ground effect?
- A reduction in induced drag when an aircraft operates within one wingspan height of the surface.
- Why is induced drag greatest at low airspeeds?
- 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.
- Form drag from the fuselage and interference drag where different aircraft components meet.
- Why is weight and balance critical for commercial aircraft operations?
- It affects center of gravity, which determines aircraft stability, handling, and performance characteristics.
- How does a forward center of gravity affect aircraft performance?
- It increases lift requirements, reduces stall margin, requires more elevator authority, and increases drag.
- Define density altitude.
- 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?
- Takeoff distance increases, rate of climb decreases, and true airspeed is higher than indicated airspeed.
- What is a temperature inversion?
- An atmospheric condition where temperature increases with altitude instead of the normal decrease.
