Adverse yaw is a force that is present as an airplane is rolled into or out of
a bank and is caused by:
-the drag of the downward deflected aileron
-use rudder to counterbalance
What happens in a skidding turn?
too much rudder, rate of turn is too fast for angle of bank
If severe turbulence is encountered, the airplane's airspeed should be
reduced to
Va-maneuvering speed
The maximum speed at which the airplane can be maneuvered and a
stall will occur before exceeding the limit load factor is:
maneuvering speed
lift equation gives this
,What is the definition of ultimate load factor?
Stress 1.5x limit load factor
-aircraft should be able to maintain load for 3 seconds w/o breaking
Asymmetrical thrust (P-factor) is a force caused by
the descending propeller blade produces more thrust
What is the definition of Torque?
a left turning force caused by the rotational mass of the engine
What determines the longitudinal stability of an airplane?
The location of center to gravity with respect to center of lift
What causes an airplane (except a T-tail) to pitch nose down when
power is reduced and controls are not adjusted?
prop wash of elevators is reduced causing a reduction of tail downforce
Dihedral is a factor in lateral stability? t/f
true
, Dutch roll is better than spiral instability? t/f
false
What are the four strokes of the internal combustion engine?
intake
compression
power
exhaust
Aircraft engines need battery power to produce spark? t/f
false
If an engine continues to run after the ignition switch is turned off, the
probable cause may be:
mag ground wire is broken and gone is hot and may start if the
propeller is turned
While making a mag check during the runup we are checking
to assure the mags are working properly and that the max drop is within
50 rpm of eachother
