(Refer to Figure 36) Upon landing, a photographer in the rear passenger position (204 lbs @ 136) moves to the front passenger seat. What effect does this have on the CG if the aircraft weighed 2,690 pounds, and the moment/100 just prior to the move was 2249.3?

The CG moves forward approximately 3.8 inches

Which statement is true regarding takeoff performance with high density altitude conditions?

The acceleration rate is slower because the engine and propeller efficiency is reduced

An aircraft is loaded with the CG at the aft limit. What are the performance characteristics compared with the CG at the forward limit?

The aft CG provides the lowest stalling speed, the highest cruising speed, and least stability

Could 100 pounds of weight be shifted from Station 30.0 to Station 120.0 without exceeding the aft CG limit? Total weight: 4,750 lb CG location: Station 115.8 Aft CG limit: Station 118.0

Yes; the new CG would be located at Station 117.69

It is possible to fly an aircraft just clear of the ground at a slightly slower airspeed than that required to sustain level flight at higher altitudes. This is the result of

interference of the ground surface with the airflow patterns about the aircraft in flight

As the CG moves aft, an aircraft becomes

less stable and less controllable

If the pressure altitude and temperature remain constant, but the air moisture content increases

the landing roll will be longer due to less dense air

Decrease cruising speed and increase stalling speed

What can a pilot expect when landing at an airport located in the mountains?

Higher true airspeed and greater vertical velocity

What can a pilot expect when landing at an airport located in the mountains?

(Refer to Figure 36) Determine the condition of the airplane Pilot: 120 lbs Passengers - aft position: 250 lbs Baggage: 100 lbs Fuel: 50 gal

Weight within limits, CG is aft of 81 inches, but within limits

To maintain level flight in an airplane which is loaded with the CG at the forward limit, an additional download must be imposed on the horizontal stabilizer. This in turn produces

an additional load which the wing must support

An airplane leaving ground effect will

experience a decrease in stability and a nose-up change in moments

The indicated lift-off airspeed for short-field takeoffs in a particular aircraft will normally be

greater than for soft- or rough-field takeoffs

If the same angle of attack is maintained in ground effect as when out of ground effect, lift will

increase, and induced drag will decrease
