ordinator? Right Ans - Slip - opposite rudder to direction of turn = ball will
be at the same side of the turn

how is the twin jet fuelled Right Ans - by fuel being pumped from the fuel
truck
what type of fire extinguisher do you use on propane fire Right Ans - foam
,what is the difference between IAS and CAS (calibrated Airspeed) Right
Ans - corrected for instrument positional errors
what is the difference between CAS and TAS (true Airspeed) Right Ans -
Corrected for changes in air Density
when is ground effect felt? Right Ans - half the wingspan from the ground
what is interference drag? Right Ans - Drag caused by interaction of
boundary layers at major aircraft components
what are high aspect ratio wings Right Ans - long thin wings
what are low aspect ratio wings Right Ans - short fat ones
why are all jet liners wings swept Right Ans - they are better at close to
mach

what is the formula for rate of descent and ground speed for a 3 degree glide
slope Right Ans - 5 x Ground speed = Rate of Descent
what air is used to cool the air in the boot leg air conditioning system?
Right Ans - Ramp air
what are the advantages of cruising at high altitudes Right Ans - faster
