Airplane Performance and Weight and Balance Flashcards
What are the standard temperature and pressure values for sea level?
15 degrees C and 29.2” Hg
What effect if any, does high humidity have aon aircraft performance?
It decreases performance
Which factor would tend to increase the density altitude at a given airport?
An increase in ambient temperature.
What effect does high density atitude, as compared to low density altitude, have on propeller efficiency and why?
Efficiency is reduced because the propeller exerts less force at high density altitudes tan at low density altitudes
What effect does high density altitude have on aircraft performance?
It reduces climb performance
Which combination of atmospheric conditions will reduce aircraft takeoff and climb performance?
High temperature, high relative humidity, and high density altitude
If the outside air temperature (OAT) at a given altitude is warmer than standard, the density altitude is
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 NSL. The service ceiling of your airplane is 14,000 feet MSL. After checking the local weather re[ort, 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?
Replan yur journey to avoid the mountain pass
If an emergency situation requires a downwind landing, pilots should expect a faster
groundspeed at touchdown, a longer ground roll, and teh likelihood of overshooting the desired touchdown point
An aircraft is loaded 110 pounds over maximum certificated gros weight. If fuel (gasoline) is drained to bring the aircraft weight within limit, how much fuel should be drained?
18.4 gallons
If an aircraft is loaded 90 pounds over maimum certificated gross weight and fuel (gasoline ) is drained to bring the aircraft weight within limits, how much fuel should be drained?
15 gallons
