If the certification category of an airplane is listed as ‘utility’ it means the airplane is intended for which maneuvers?
All nonacrobatic maneuvers plus limited acrobatics including spins.
Which is the correct symbol for the minimum steady flight speed at which an airplane is controllable?
V(S)
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
Additional load which the wing must support.
What would be the new CG location if 135 pounds of weight were added at
Station 109.0?
Total weight 2340 lb
CG location station 103.0
Station 103.3.
Could 100 pounds of weight be shifted from station 130.0 to station 30.0 without exceeding the forward CG limit?
Total weight 2800 lb
CG location station 120.0
Forward CG limit station 117.0
No; the CG would be located at station 116.42.
Could 100 pounds of weight be shifted from station 30.0 to station 120.0 without exceeding the aft CG limit?
Total weight 4750 lb
CG location station 115.8
After CG limit station 118.0
Yes; the new CG would be located at station 117.69.
The indicated lift off speed for short field takeoffs in a particular aircraft will normally be
Greater then for soft or rough field takeoffs.
If the same angle of attack is maintained in ground effect as when out of ground effec,t lift will
Increase, and induced drag will decrease.
It is possible to fly an aircraft just clear the ground at a slightly slower airspeed than that required to sustain level flight at higher speeds this is the result of
Interference of the ground surface with the airflow patterns about the aircraft in flight.
An airplane leaving ground effect will
Experience a decrease in stability and a noseup change in moments.
How should the 1,000 pound weight be shifted to balance the plank on the fulcrum?
5 inches to the right.
How should the 500 pound weight be shifted to balance the plank on the fulcrum?
10 inches to the right.
How should the 200 pound weight be shifted to balance the plank on the fulcrum?
2.5 inches to the left.
How should the 500 pound weight be shifted to balance the plank on the fulcrum?
1 inch to the left.
If 50 pounds of weight is located at point X and 100 pounds at point Z how much weight must be located at point Y to balance the plank?
300 pounds.
If 50 pounds of weight is located at point X and 100 pounds at point Y how much weight must be located at point Z to balance the plank?
50 pounds.
How much weight could be added at station 160 without exceeding the aft CG limit?
Aircraft weight 8300 lb
CG location station 90.0
Aft CG limit station 90.5
59.7 pounds.
What is the location of the CG if 90 pounds are removed from station 140?
Aircraft weight 6230 lb
CG location Station 79
78.1.
What is the location of the CG if 146 pounds are removed from station 150?
Aircraft weight. 7152 lb
CG location station 82
80.6.
An aircraft is loaded with the CG aft of the aft limit. What affect will this have on controllability?
Stall and spin recovery may be difficult or impossible.
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.
If the center of gravity of an aircraft is moved from the aft limit to be on the forward limit, how will it affect cruising and stalling speed?
Decrease cruising speed and increase stalling speed.
As the CG moves aft, an aircraft becomes
Less stable and less controllable.
What is characteristic of the indicated airspeed if this CG is at the most forward allowable position and constant power and altitude are maintained?
Indicated airspeed will be less than it would be when the CG in the most rearward allowable position.
