Basics Flashcards
FAA Advisory Circulars are available to all pilots and are obtained by
Downloading them from the FAA website
FAA advisory circulars containing subject matter specifically related to Airspace are issued under which subject number?
70
An airplane said to be inherently stable will
Require less effort to control
As an airplane’s CG moves aft, the airplane becomes
Less stable at all airspeeds
What is the purpose of the rudder on an airplane?
To control yaw
What determines the longitudinal stability of an airplane?
The location of the CG with respect to the center of lift.
One of the main functions of flaps during approach and landing is to
Increase the angle of descent without increasing the airspeed.
After takeoff, which airspeed should the pilot use to gain the most altitude in a given period of time?
Vy
Trim systems are designed to do what?
They relieve the pilot of the need to maintain constant back pressure on the flight controls.
To minimize the side loads placed on the landing gear during touchdown, the pilot should keep the…
longitudinal axis of the aircraft parallel to the direction of its motion.
Longitudinal stability refers to an aircraft’s stability about which axis?
Lateral
Which would provide the greatest gain in altitude in the shortest distance during a climb after takeoff?
Vx
What causes an airplane (except a T-tail) to pitch nosedown when power is reduced and controls are not adjusted?
The downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced.
FAA advisory circulars containing subject matter specifically related to Air Traffic Control and General Operations are issued under which subject number?
90
Changes in the center of pressure of a wing affect the aircraft’s
aerodynamic balance and controllability.
What is one purpose of wing flaps?
allow the pilot to make steeper approaches to a landing without increasing airspeed.
In comparison to an airplane with a conventional tail, a T-tail airplane (such as a Diamond DA-40) is
more susceptible to stall recovery difficulties because the elevator is above the propeller slipstream.
Loading an airplane to the most aft CG will cause the airplane to be
Less stable at all speeds
An airplane has been loaded in such a manner that the CG is located aft of the CG limit. One undesirable flight characteristic a pilot might experience would be
Difficulty in recovering from a stall
An airplane has been loaded in such a manner that the CG is located aft of the aft CG limit. One undesirable flight characteristic a pilot might experience with this airplane would be
Difficulty in recovering from a stalled condition
FAA advisory circulars containing subject matter specifically related to Airmen are issued under which subject number?
60

3402.5
Your airplane underwent an annual inspection on June 15 of last year. When is the next annual inspection due?
June 30th this year
Where might the aircraft’s Operating Limitations be found?
Onboard the aircraft, usually in the Pilot’s Operating Handbook and required placards.
