3. If, after travelling 40nm on a heading of 046(m), an aircraft’s
position is fixedas 4nm left of the track of 055(m) the new heading to
parallel track would be:
(a ) 052(m) and the drift has been 3 degrees left.
(b ) 052(m) and the drift has been 3 degrees right.
(c ) 058(m) and the drift has been 3 degrees left.
(d ) 058(m) and the drift has been 3 degrees right.

4. If, after maintaining the desired track of 120(m) using a heading of
128(m)it was wisely decided to return to the destination due to weather,
the
appropriate initial heading would be:

(a ) 308(m)
(b ) 292(m)
(c ) 300(m)
(d ) 316(m)

At an altitude of 5000 feet, the theoretical VHF range of a ground station
at an elevation of 1000 feet is approximately:a ) 88 kilometers
b ) 68 kilometers
c ) 88 nautical miles
d ) 68 nautical miles

Flight levels are:
a ) pressure heights
b ) density heights
c ) pressure heights corrected for pressure deviation from ISA
d ) density heights corrected for temperature deviation from ISA

The best power-off glide speed corresponds to the:
a ) best lift-drag ration and increases with decreasing weight
b ) best lift-drag ration and reduces with decreasing weight
c ) lowest induced drag and increases with decreasing weight
c ) lowest induced drag and reduces with decreasing weight

2. A directional indicator employs a:
(c ) space gyro and, unless corrected for latitude, will drift at a rate that increases
with latitude.

... не надо все сваливать на Алексея, он и так это все знает.

1. Skin friction drag resulting from a laminar boundary layer will be:
a) more than a turbulent boundary layer
b) less than from a turbulent boundary layer
c) the same as from a turbulent boundary layer

If more power is required to maintain altitude when indicated airspeed is reduced, the aeroplane must be flying below:
(a) Vno (maximum structural cruising speed)
(b) the speed for maximum endurance
© the speed for best angle of climb
(d) the speed for minimum drag

2. If the weight of an aircraft is increased, for a constant speed:

a) profile drag will increase, induced drag will remain the same
b) induced drag will increase, profile drag will remain the same
c) both profile drag and induced drag will remain the same
d) profile drag will increase, induced drag will decrease

demid, если для уменьшения скорости требуется увеличение мощности, то значит ты летишь на back side of the speed curve - то есть на негативной стороне кривой мощности. Т.е. задираешь нос (увеличивая угол атаки, растет торможение, причем induced drag)

3. The most correct list of factors affecting the leift produced by an aerofoil are:
a) AoA, air density, velocity, wing area
b) AoA, air temperature, velocity, wing area
c) AoA, velocity, wing area, aerofoil section, air density
d) incidence, TAS, wing plan, leading edge radius and thrust

подъемная сила зависит от сл. факторов - угол атаки, скорость, площадь крыла, профиль крыла, плотность воздуха, ответ Чарли.

5. Increased downwash:
a) reduces effective AoA of the tailplane
b) increases effective AoA of the tailplane
c) reduces effective AoA of the tailplane if it has a positive camber
d) doesn't affect the effective AoA of the tailplane
