81 H928 PVT What is one procedure to aid in cooling an engine that is overheating? A) Enrichen the fuel mixture. B) Increase the RPM. C) Reduce the airspeed. 82 H928 PVT If the engine oil temperature and cylinder head temperature gauges have exceeded their normal operating range, the pilot may have been operating with A) the mixture set too rich. B) higher-than-normal oil pressure. C) too much power and with the mixture set too lean. 83 H928 PVT During the run-up at a high-elevation airport, a pilot notes a slight engine roughness that is not affected by the magneto check but grows worse during the carburetor heat check. Under these circumstances, what would be the most logical initial action? A) Check the results obtained with a leaner setting of the mixture. B) Taxi back to the flight line for a maintenance check. C) Reduce manifold pressure to control detonation. 84 H928 PVT The basic purpose of adjusting the fuel/air mixture at altitude is to A) decrease the amount of fuel in the mixture in order to compensate for increased air density. B) decrease the fuel flow in order to compensate for decreased air density. C) increase the amount of fuel in the mixture to compensate for the decrease in pressure and density of the air. 85 H928 PVT An abnormally high engine oil temperature indication may be caused by A) the oil level being too low. B) operating with a too high viscosity oil. C) operating with an excessively rich mixture. 86 H928 PVT A precaution for the operation of an engine equipped with a constant-speed propeller is to A) avoid high RPM settings with high manifold pressure. B) avoid high manifold pressure settings with low RPM. C) always use a rich mixture with high RPM settings. 87 H928 PVT How is engine operation controlled on an engine equipped with a constant-speed propeller? A) The throttle controls power output as registered on the manifold pressure gauge and the propeller control regulates engine RPM. B) The throttle controls power output as registered on the manifold pressure gauge and the propeller control regulates a constant blade angle. C) The throttle controls engine RPM as registered on the tachometer and the mixture control regulates the power output. 88 H928 PVT What effect does high density altitude, as compared to low density altitude, have on propeller efficiency and why? A) Efficiency is increased due to less friction on the propeller blades. B) Efficiency is reduced because the propeller exerts less force at high density altitudes than at low density altitudes. C) Efficiency is reduced due to the increased force of the propeller in the thinner air. 89 J13 PVT When should pilots decline a land and hold short (LAHSO) clearance? A) Pilots can not decline clearance. B) Only when the tower operator concurs. C) When it will compromise safety. 90 J13 PVT Who should not participate in the Land and Hold Short Operations (LAHSO) program? A) Recreational pilots only. B) Student pilots. C) Military pilots. 91 J03 PVT A slightly high glide slope indication from a precision approach path indicator is A) four white lights. B) three white lights and one red light. C) two white lights and two red lights. 92 J03 PVT An airport's rotating beacon operated during daylight hours indicates A) there are obstructions on the airport. B) that weather at the airport located in Class D airspace is below basic VFR weather minimums. C) the Air Traffic Control tower is not in operation. 93 J03 PVT To set the high intensity runway lights on medium intensity, the pilot should click the microphone seven times, and then click it A) one time within four seconds. B) three time within three seconds. C) five times within five seconds. 94 H568 PVT Airport taxiway edge lights are identified at night by A) white directional lights. B) blue omnidirectional lights. C) alternate red and green lights. 95 J03 PVT (Refer to figure 48.) Illustration A indicates that the aircraft is A) below the glide slope. B) on the glide slope. C) above the glide slope. 96 J03 PVT An above glide slope indication from a tri-color VASI is A) a white light signal. B) a green light signal. C) an amber light signal. 97 J03 PVT A below glide slope indication from a pulsating approach slope indicator is a A) pulsating white light. B) steady white light. C) pulsating red light. 98 J03 PVT A below glide slope indication from a tri-color VASI is a A) red light signal. B) pink light signal. C) green light signal. 99 J05 PVT (Refer to figure 49.) Area C on the airport depicted is classified as a A) stabilized area. B) multiple heliport. C) closed runway. 100 J05 PVT (Refer to figure 49.) What is the difference between area A and area E on the airport depicted? A) 'A' may be used for taxi and takeoff; 'E' may be used only as an overrun. B) 'A' may be used for all operations except heavy aircraft landings; 'E' may be used only as an overrun. C) 'A' may be used only for taxiing; 'E' may be used for all operations except landings.
