1 Gleim FAA Test Prep: Private Pilot (12 questions) Study Unit 5 [Airplane Performance and Weight and Balance] Name: Date: [1] Gleim #: Source: AvW Chap 3 Which factor would tend to increase the density altitude at a given airport? An increase in barometric pressure. A decrease in relative humidity. An increase in ambient temperature. [2] Gleim #: Source: PHAK Chap 10 What effect does high density altitude have on aircraft performance? It increases takeoff performance. It reduces climb performance. It increases engine performance. [3] Gleim #: Source: PHAK Chap 10 (Refer to Figure 8.) What is the effect of a temperature increase from 30 to 50 F on the density altitude if the pressure altitude remains at 3,000 feet MSL? 1,100-foot decrease. 900-foot increase. 1,300-foot increase.

4 Gleim FAA Test Prep: Private Pilot (12 questions) Study Unit 5 [Airplane Performance and Weight and Balance] [10] Gleim #: Source: PHAK Chap 9 (Refer to Figure 62.) 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. 50 pounds. 30 pounds. [11] Gleim #: Source: PHAK Chap 9 (Refer to Figure 35.) What is the maximum amount of baggage that may be loaded aboard the airplane for the CG to remain within the moment envelope? WEIGHT (LB) MOM/1000 Empty weight 1, Pilot and front passenger Rear passengers Baggage Fuel, 30 gal Oil, 8 qt pounds. 110 pounds. 120 pounds. [12] Gleim #: Source: PHAK Chap 9 (Refer to Figure 33, Figure 34.) Calculate the weight and balance and determine if the CG and the weight of the airplane are within limits. Front seat occupants Rear seat occupants Baggage Fuel 350 lb 325 lb 27 lb 35 gal CG 83.4, within limits. CG 84.1, within limits. CG 81.7, out of limits forward. Copyright 2011 Gleim Publications Inc.
