Which items are included in the empty weight of an aircraft?
|
- unusable fuel and undrainable oil
- full fuel tanks and engine oil to capacity - Only the airframe, powerplant, and optional equipment |
unusable fuel and undrainable oil
|

An aircraft is loaded 110 pounds over maximum certificated gross weight. If fuel (gasoline) is drained to bring the aircraft weight within limits, how much fuel should be drained?
|
- 15.7 gallons
- 18.4 gallons - 16.2 gallons |
18.4 gallons
|
|
|
If an aircraft is loaded 90 pounds over maximum certificated gross weight and fuel (gasoline) is drained to bring the aircraft weight within limits, how much fuel should be drained?
|
- 12 gallons
- 15 gallons - 10 gallons |
15 gallons

|
What are the standard temperature and pressure values for sea level?
|
- 59 degrees C and 1013.2 millibars
- 15 degrees C and 29.92 inches Hg - 59 degrees F and 29.92 millibars |
15 degrees C and 29.92 inches Hg

|
What effect, if any, does high humidity have on aircraft performance?
|
- it has no effect on performance
- it decreases performance - it increases performance |
it decreases performance
|
|
|
Which factor would tend to increase the density altitude at a given airport?
|
- an increase in ambient temperature
- an increase in barometric pressure - a decrease in relative humidity |
an increase in ambient temperature
|
|
|
What effect does high density altitude, as compared to low density altitude, have on propeller effeciency and why?
|
- efficiency is reduced due to the increased force of the propeller in the thinner air
- efficiency is increased due to less friction on the propeller blades - efficiency is reduced because the propeller exerts less force at high density altitudes than at low density altitudes |
efficiency is reduced because the propeller exerts less force at high density altitudes than at low density altitudes
|
|
|
What effect does high density altitude have on aircraft performance?
|
- it reduces climb performance
- it increases engine performance - it increases takeoff performance |
it reduces climb performance
|
|
|
Which combination of atmospheric conditions will reduce aircraft takeoff and climb performance?
|
- high temperature, low relative humidity, and low density altitude
- low temperature, low relative humidity, and low density altitude - high temperature, high relative humidity, and high density |
high temperature, high relative humidity, and high density
|
|
|
If the outside air temperature (OAT) at a given altitude is warmer than standard, the density altitude is?
|
- lower than pressure altitude
- higher than pressure altitude - equal to pressure altitude |
higher than pressure altitude
|

You have planned a cross-country flight on a warm spring morning. Your course includes a mountain pass, which is at 11,500 feet MSL. The service ceiling of your airplane is 14,000 feet MSL. After checking the local weather report, you are able to calculate the density altitude of the mountain pass as 14,800 feet MSL. Which of the following is the correct action to take?
|
- continue as planned because mountain thermals will assist your climb
- replan your journey to avoid the montain pass - continue as planned since density altitude is only a factor for takeoff |
replan your journey to avoid the mountain pass

Empty weight:
- WEIGHT (LB) = 1,495.0 - ARM (IN) = 101.4 - MOMENT (LB-IN) = 151,593.0 Pilot and passengers: - WEIGHT (LB) = 380.0 - ARM (IN) = 64.0 - MOMENT (LB-IN) = ------ Fuel (30 gal usable no reserve): - WEIGHT (LB) = ------- - ARM (IN) = 96.0 - MOMENT (LB-IN) = ----- The CG is located how far aft of datum? |
- CG 94.01
- CG 119.8 - CG 94.01 |
CG 94.01
