1. What is Dutch roll? - ANSWER A yawing and rolling moment created by
the advancing wing meeting greater airflow than the retreating wing in a
sweptback design.
2. Mach buffet occurs when: - ANSWER Occurs when shock waves on top
of the wings interfere with the airflow causing turbulent airflow from the
wings to strike the tail surface.
3. Weight Shift Formula - ANSWER wt/WT = d/D
4. Wake turbulence - heaviest vortices: - ANSWER Heavy, slow moving
and CLEAN aircraft.
5. refraction errors - ANSWER Can cause you to appear that you're lower
than you really are.
6. Increased performance wind shear is caused by: - ANSWER Headwind
being stronger closer to the ground.
,1. Increases airspeed
2. Sink decreases
3. Aircraft rises above glide path
4 Needs a higher power setting than before to maintain profile.
5 Increased performance wind shear = increased power and airspeed
7. Decreased performance wind shear - ANSWER Caused by decreasing
headwind at the ground level.
1. Loss of airspeed
2. Lift decreases
Less power is needed to maintain proper glideslope profile
8. Uncontrolled airspace flight visibility below 1000 AGL - ANSWER 2 miles
day, 3 miles night, clear of cloud
9. Uncontrolled airspace flight visibility above 1000 AGL - ANSWER 1 mild
day, 3 miles night, 2000 horizontally, 500 vertical
10.Point of No Return (PNR) formula - ANSWER Distance to PNR = Fuel x
GS return x GS outbound / GS return + GS outbound
11.Point of Equal time (PET) or Critical Point (CP) - ANSWER Dpet = Dtotal x
GS return / GS return + GS continue
, 12.Maximum airspeed while in a hold above 14000 feet turbojet - ANSWER
265 KIAS
13.Maximum airspeed while climbing in a hold turbojet - ANSWER 310
KIAS
14.Turbojet minimum dispatch landing distance required at the aerodrome -
ANSWER 60%
15.Engine Pressure Ratio (EPR) - ANSWER Ratio of the total pressure of the
exhaust stream to the total pressure of the inlet air.
16.N1 - ANSWER Speed of the low pressure turbine
17.N2 - ANSWER Speed of the high pressure compressor. Usually not used
for engine performance value but is still a good measurement of engine
health.
18.What is maneuvering speed? - ANSWER The highest speed at which the
air craft can be stalled without damage to the aircraft
19.Of the air passing through a turbine engine, _______ is involved with the
combustion process and the fuel air ratio is approximately ________ -
ANSWER 30%, 15:1
