An airplane is loaded to a gross weight of 4,800 pounds, with three pieces of luggage in the rear
baggage compartment. The CG is located 98 inches aft of datum, which is 1 inch aft of limits. If
luggage which weighs 90 pounds is moved from the rear baggage compartment (145 inches aft of
datum) to the front compartment (45 inches aft of datum), what is the new CG?
96.13 inches aft of datum.
95.50 inches aft of datum.
99.87 inches aft of datum. - ANSWER: 96.13 inches aft of datum.
Refer to Figure 8.) With 38 gallons of fuel aboard at cruise power (55 percent), how much flight time is
available with night VFR fuel reserve still remaining?
2 hours 34 minutes.
2 hours 49 minutes.
3 hours 18 minutes - ANSWER: 2 hours 34 minutes.
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. - ANSWER: the unusable fuel, full operating fluids, and full oil.
When diverting to an alternate airport because of an emergency, pilots should
rely upon radio as the primary method of navigation.
climb to a higher altitude because it will be easier to identify checkpoints.
apply rule-of-thumb computations, estimates, and other appropriate shortcuts to divert to the new
course as soon as possible. - ANSWER: apply rule-of-thumb computations, estimates, and other
appropriate shortcuts to divert to the new course as soon as possible.
At higher elevation airports the pilot should know that indicated airspeed
will be unchanged, but groundspeed will be faster.
will be higher, but groundspeed will be unchanged.
should be increased to compensate for the thinner air. - ANSWER: will be unchanged, but
groundspeed will be faster.
