1,525 feet
1,950 feet
1,775 feet
1,775 feet
- To minimize the side loads placed on the landing gear during touchdown, the pilot should keep:
direction of motion of the aircraft parallel to the runway.
down wing lowered sufficiently to eliminate the tendency for the aircraft to drift.
longitudinal axis of the aircraft parallel to the direction of its motion.
longitudinal axis of the aircraft parallel to the direction of its motion.

- If an altimeter setting is not available before flight, to which altitude should the pilot adjust the altimeter?
The elevation of the nearest airport corrected to mean sea level.
The elevation of the departure area.
Pressure altitude corrected for nonstandard.
The elevation of the departure area.
- If it is necessary to set the altimeter from 29.15 to 29.85, what change occurs?
700-foot increase in indicated altitude.
70-foot increase in indicated altitude.
70-foot increase in density altitude.
700-foot increase in indicated altitude.
- Loading an airplane to the most aft CG will cause the airplane to be:
less stable at slow speeds, but more stable at high speeds.
less stable at high speeds, but more stable at low speeds.
less stable at all speed.
less stable at all speed.
- The angle of attack at which an airplane wing will stalls:
increase if the CG is moved forward
remain the same regardless of gross weight.
change with an increase in gross weight.
remain the same regardless of gross weight.
- When computing weight and balance, the basic empty weight includes the weight of the airframe, engine(s), and all installed optional equipment. Basic empty weight also includes?
The unusable fuel, full operating fluids, and full oil
All usable fuel, full oil, hydraulic fluid, but does not include the weight of pilot, passengers, or baggage
All usable fuel and oil, but does not include any radio equipment or instruments that were installed by someone other than the manufacturer
The unusable fuel, full operating fluids, and full oil

7 knots
15 knots
17 knots
17 knots
- (Refer to figure 11) If the cruise altitude is 7,500 feet, using 64 percent power at 2,500 RPM, what would be the range with 48 gallons of usable fuel?
635 miles
645 miles
810 miles
810 miles
- (Refer to figure 11) What would be the endurance at an altitude of 7,500 feet, using 52 percent power?
NOTE: with 48gallons of fuel – no reserve
6.1 hours
7.7 hours
8.0 hours
7.7 hours
- (Refer to figure 11) What would be the approximate true airspeed and fuel consumption per hour at an altitude of 7,500 feet, using 52 percent power?

105 MPH TAS, 6.6 GPH
105 MPH TAS, 6.2 GPH
105 MPH TAS, 6.2 GPH
- The CG of an aircraft may be determined by:
dividing total arms by total moments
dividing total moments by total weight
multiplying total weight by total moments
dividing total moments by total weight
- The CG of an aircraft can be determine by which of the following method’s?
Dividing total arms by total moments
Multiplying total arms by total weight
Dividing total moments by total weight
Dividing total moments by total weight
