PPAER practice test (General
Knowledge) practice test.
What would happen if you used an 80/87 octane fuel in an aircraft that normally uses 100LL? - Answer-
most likely cause detonation
What is the difference between the utility category and the normal category? - Answer-Utility category
allows the practice of aerobatic maneuvers that are approved by the manufacturer. In the normal
category the aircraft must be loaded and operated in normal flight. Stalls and spins for example would
be prohibited.
What is basic empty weight? - Answer-Weight of the aircraft empty with unusable fuel.
What kind of illusion would you expect if you were landing on a runway with a downslope - Answer-The
illusion will be that you are too low and you will fly a steeper than normal approach.
When would you use Va - Answer-it is used in turbulence
What is a spiral dive? - Answer-A steep descending turn with altitude decreasing rapidly and airspeed
increasing rapidly.
, What does a red light over a white light on a VASIS during an approach mean? - Answer-You are on the
correct glide path - Red over White, you're all right.
How long can hazardous wake turbulence caused by an aircraft in still air last? - Answer-it may persist
for 2 or minutes.
Calculate moment? - Answer-Weight X arm = moment.
Does the indicated stall speed of an airplane change with altitude? - Answer-No, the indicated stall
speed does not change with altitude.
What kind of illusion will you expect on approach to a narrow runway? - Answer-You get the illusion
that you are too high on approach.
True altitude? - Answer-Height above sea level
What is the definition of datum? - Answer-This is a point on the aircraft where all distances are
measured for weight and balance purposes. For example, on many Cessna aircraft the reference datum
is the fire wall.
What type of illusions will occur when flying into rain? - Answer-Objects will appear to be lower than
they actually are.
How do you normally convert AVGAS in gallons to pounds assuming standard temperature? - Answer-
The number of gallons x 6.0 = AVGAS in pounds.
What corrective action should be used following a wheelbarrow situation? - Answer-Close the throttle
and apply back pressure to place more weight on the main wheels. Another option is to over-shoot and
go-around.
