212 free questions with answers and explanations.
- 201.An airplane is equipped with a fixed-pitch propeller. Compared to an airplane with a constant-speed propeller, how does the fixed-pitch propeller affect high-altitude climb performance?Aerodynamics and Performance
- 202.An airplane has a maximum positive limit load factor of +3.8G. During a flight, the pilot encounters severe turbulence causing the vertical acceleration to briefly reach +4.5G. What is the immediate consequence of this event?Aerodynamics and Performance
- 203.An airplane is flying at an altitude where its true airspeed (TAS) is 150 knots and the outside air temperature (OAT) is -10°C. If the speed of sound at this altitude and temperature is approximately 630 knots, what is the airplane's Mach number?Aerodynamics and Performance
- 204.A pilot is flying an airplane that is in the region of reverse command. What characteristic describes the relationship between airspeed and power in this flight regime?Aerodynamics and Performance
- 205.During a cross-country flight, a pilot notices that the airplane's total drag is at its minimum. At this point, what is the relationship between parasite drag and induced drag?Aerodynamics and Performance
- 206.An airplane is equipped with a supercharger. What is the primary benefit of a supercharger for aircraft performance?Aerodynamics and Performance
- 207.A pilot is conducting a high-altitude cruise flight. What is the primary reason that maintaining a constant Mach number is often preferred over maintaining a constant indicated airspeed (IAS) for optimal performance at high altitudes?Aerodynamics and Performance
- 208.A pilot is planning a high-altitude flight in an unpressurized aircraft. Which physiological effect is a primary concern at altitudes above 10,000 feet without supplemental oxygen?Aerodynamics and Performance
- 209.A pilot is performing a rapid descent at a high rate of speed. During the recovery, the pilot pulls back on the control stick, imposing a load factor of +4.0G. If the airplane's unaccelerated (1G) stall speed is 60 KCAS, what is the accelerated stall speed in this maneuver?Aerodynamics and Performance
- 210.A pilot is flying a high-performance airplane at a constant indicated airspeed (IAS) and bank angle during a climbing turn. As the airplane gains altitude, what effect will this have on the true airspeed (TAS) and the radius of the turn?Aerodynamics and Performance
- 211.A commercial pilot is performing a flight under Part 91, carrying passengers for compensation or hire. What is the minimum medical certificate required for this pilot?Regulations
- 212.A commercial pilot is conducting a flight for compensation or hire. The aircraft has an inoperative communication radio. Under what conditions, if any, may this flight proceed under Part 91?Regulations
