Practice test
  1. 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
  2. 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
  3. 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
  4. 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
  5. 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
  6. 206.An airplane is equipped with a supercharger. What is the primary benefit of a supercharger for aircraft performance?Aerodynamics and Performance
  7. 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
  8. 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
  9. 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
  10. 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
  11. 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
  12. 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
