Bank oscillations becoming progressively greater C. Aircraft constantly tries to pitch down A. Pitch oscillations becoming progressively greater Maximum range performance of a turbojet aircraft is obtained by which procedure as aircraft weight reduces? A. Increasing speed or altitude B. Increasing altitude or decreasing speed C. Increasing speed or decreasing altitude B. Increasing altitude or decreasing speed What effect does high relative humidity have upon the maximum power output of modern aircraft engines? A. Neither turbojet nor reciprocating engines are affected B. Reciprocating engines will experience a significant loss of BHP C. Turbojet engines will experience a significant loss of thrust B. Reciprocating engines will experience a significant loss of BHP What effect would a change in ambient temperature or air density have on gas-turbine-engine performance? A. As air density decreases, thrust increases B. As temperature increases, thrust increases C. As temperature increases, thrust decreases C. As temperature increases, thrust decreases What effect, if any, does high ambient temperature have upon the thrust output of a turbine engine? A. Thrust will be reduced due to the decrease in air density B. Thrust will remain the same, but turbine temperature will be higher C. Thrust will be higher because more heat energy is extracted from the hotter air A. Thrust will be reduced due to the decrease in air density What effect will an increase in altitude have upon the available equivalent shaft horsepower (ESHP) of a turboprop engine? A. Lower air density and engine mass flow will cause a decrease in power B. High propeller efficiency will cause an increase in usable power (ESHP) and thrust C. Power will remain the same but propeller efficiency will decrease A. Lower air density and engine mass flow will cause a decrease in power What characterizes a transient compressor stall? A. Loud steady roar accompanied by heavy shuddering B. Sudden loss of thrust accompanied by a loud whine C. Intermittent "bang," as backfires and flow reversals take place C. Intermittent "bang," as backfires and flow reversals take place What indicates that a compressor stall has developed and become steady? A. Strong vibrations and loud roar B. Occasional loud "bang" and flow reversal C. Complete loss of power with severe reduction in airspeed A. Strong vibrations and loud roar What recovery would be appropriate in the event of compressor stall? A. Reduce the throttle and then rapidly advance the throttle to decrease the angle of attack on the compressor blades, creating more airflow B. Reduce the throttle and then slowly advance the throttle again to decrease the angle of attack on one or more compressor blades C. Advance the throttle slowly to increase airflow and decrease the angle of attack on one or more compressor blades C.
