PRIVATE PILOT GROUND SCHOOL
EXAM Q&A
Form drag - ANSWER-The turbulent wake caused by the separation of airflow from
the surface of a structure
Interference drag - ANSWER-When the airflow around one part of the airplane
interacts with the airflow around and adjacent part
Skin friction drag - ANSWER-Caused by the roughness of the airplanes surfaces
Induced drag - ANSWER-Generated by the airflow circulation around the wings as it
creates lift
Stability - ANSWER-The characteristic of an airplane in flight that causes it to return
to a condition of equilibrium, or steady flight, after it is disturbed
Positive static stability - ANSWER-The initial tendency to return to the position from
which it was displaced
Center of gravity - ANSWER-Which is the theoretical point where the entire weight of
the airplane is considered to be concentrated
Center of pressure - ANSWER-A point along the wing chord line where lift is
considered to be concentrated
Va - ANSWER-Maximum speed
Detonation - ANSWER-An uncontrolled, exposive ignition of the fuel/air mixture
within the cylinders combustion chamber
Pre-ignition - ANSWER-Occurs when the fuel/air mixture is ignited in advance of the
normal timed ignition
80/87 - ANSWER-Red fuel
100LL - ANSWER-Blue fuel
100/130 - ANSWER-Green fuel
Jet - ANSWER-Clear fuel
Gyroscopic - ANSWER-Altitude indicator, Turn coordinator, Heading indicator
Magnetic - ANSWER-Magnetic Compass
Pitot-Static - ANSWER-Airspeed indicator, Altimeter, Vertical speed indicator
