2.13 With increasing altitude, the power required curve moves:
(a) up and to the right
(b) down and to the right
(c) up and to the left
(d) down and to the left - CORRECT ANSWER-(a) up and to the right
2.14 For a piston engine airplane at a constant mass, AOA, and configuration, an
increase of altitude will require:
(a) increased power but the same TAS
(b) increased power and TAS
(c) lower power but increased TAS
(d) the same power but an increased TAS - CORRECT ANSWER-(b) increased
power and TAS
2.15 For a piston engine airplane at a constant altitude, AOA, and configuration,
an increased mass will require:
,(a) more power and speed
(b) more power but the same speed
(c) the same power but more speed
(d) more power but less speed - CORRECT ANSWER-(a) more power and speed
2.16 The region of reversed command means:
(a) a lower airspeed requires more thrust
(b) the thrust required is independent of airspeed
(c) a thrust reduction results in acceleration
(d) a momentary increase of airspeed has no influence on the thrust required -
CORRECT ANSWER-(a) a lower airspeed requires more thrust
2.17 At speeds below Vimd:
(a) the airplane can only be controlled in level flight
(b) a lower speed requires more thrust
(c) a higher speed requires more thrust
(d) the airplane cannot be controlled manually - CORRECT ANSWER-(b) a lower
speed requires more thrust

,(a) in a descent at constant IAS
(b) in level flight at constant IAS
(c) in level flight accelerating
(d) in a climb at constant IAS - CORRECT ANSWER-(b) in level flight at constant
IAS

(a) it increases with increased altitude
(b) it decreases with increased altitude
(c) it remains constant with increased altitude
(d) it decreases with decreased altitude - CORRECT ANSWER-(c) it remains
constant with increased altitude
2.20 Maximum horizontal speed occurs when:
(a) thrust = minimum drag
(b) thrust does not increase with increasing speed
(c) maximum thrust = total drag
(d) thrust = maximum drag - CORRECT ANSWER-(c) maximum thrust = total
drag

(a) lowest practical altitude
(b) optimum cruise altitude
(c) service ceiling
(d) practical ceiling - CORRECT ANSWER-(a) lowest practical altitude
1.1 A jet aeroplane flying for max endurance has a mass decrease, because of fuel
used, by 5% from its original mass, the change to the fuel consumption per hour
from that at the original mass is:
(a) increase by 5%
(b) decrease by 5%
(c) increase by 10%
(d) decrease by 10% - CORRECT ANSWER-(b) decrease by 5%
1.6 At a constant thrust setting and altitude the fuel flow of a jet engine:
(a) decreases with decreasing OAT
(b) increases slightly with increasing speed
(c) is independent of speed
(d) decreases slightly with increasing speed - CORRECT ANSWER-(b) increases
slightly with increasing speed
