77. External air leakage from the APU heat shield area is allowable.

Explanation

External air leakage from the APU heat shield area is allowable because the APU (Auxiliary Power Unit) is designed to generate heat, and some amount of air leakage is expected. This leakage helps to dissipate the heat generated by the APU and prevent overheating. Additionally, the APU heat shield is designed to protect surrounding components from excessive heat, so any leakage from this area is not considered a safety concern.

Submit
78. What does a HIGH light and automatic shutdown of theAPU during normal operation indicate?

Explanation

A HIGH light and automatic shutdown of the APU during normal operation indicates an overspeed condition. This means that the APU is running at a higher speed than it is designed to handle, which can be dangerous and potentially cause damage to the system. As a safety measure, the APU automatically shuts down to prevent any further issues or potential accidents.

Submit
79. In the event of an aborted start, the engine must be motored a minimum of how many seconds in order to prevent an engine fire ?

Explanation

In the event of an aborted start, the engine must be motored for a minimum of 30 seconds in order to prevent an engine fire. This is because during the start-up process, fuel can accumulate in the engine without being burned. Motoring the engine for 30 seconds helps to clear out any excess fuel and prevents it from igniting and causing a fire.

Submit
80. Standby engine display should be rotated to what position for POWER RUNS?

Explanation

The correct answer is EPR. EPR stands for Engine Pressure Ratio, which is a measure of the pressure difference between the inlet and outlet of the engine. During power runs, it is important to monitor the EPR to ensure that the engine is operating within safe limits and producing the desired amount of power. Therefore, the standby engine display should be rotated to the EPR position for power runs.

Submit
83. Engines may be started with the flaps down

Explanation

Engines may be started with the flaps down because the flaps are not directly related to the engine starting process. Flaps are aerodynamic devices on the wings of an aircraft that are used to increase lift during takeoff and landing. They are not involved in the engine startup sequence, which typically includes tasks such as fueling, ignition, and engine rotation. Therefore, the position of the flaps does not affect the ability to start the engines.

Submit
84. Hydraulic system 2 may require ___________ Seconds to reach full system pressure.

Explanation

In a hydraulic system, the time required to reach full system pressure depends on various factors such as the size of the system, the power of the pump, and the fluid flow rate. In this case, hydraulic system 2 may require 45 seconds to reach full system pressure. This suggests that the system is moderately sized and has a moderate pump power and fluid flow rate, allowing it to reach the desired pressure within a reasonable time frame.

Submit
85. What is the engine starter duty cycle?

Explanation

The engine starter duty cycle refers to the duration of time the engine starter is operated and the subsequent time it is turned off. In this case, the correct answer states that the engine starter is operated for 5 minutes, during which the N2 (the rotational speed of the engine's low-pressure compressor) stops completely. After this, there is a 5-minute period of rest before the cycle repeats. This duty cycle allows for the engine starter to be activated for a specific duration and then given a break to prevent overheating or excessive wear on the starter system.

Submit
86. What is the minimum amount of oil prior to engine start?

Explanation

The minimum amount of oil prior to engine start is 13 qts. This means that the engine requires at least 13 quarts of oil in order to function properly and avoid any potential damage or malfunction. Having less than 13 qts of oil could result in inadequate lubrication and increased friction, leading to engine overheating and other issues.

Submit
87. An APU fire is indicated by which of the following

Explanation

The correct answer is "Master warning lights on instrument panel, APU display." This is because when there is an APU fire, the master warning lights on the instrument panel and the APU display will indicate the fire. These warning lights are designed to alert the crew to the presence of a fire in the APU system, allowing them to take appropriate action to mitigate the situation.

Submit
88. Maximum EGT during APU startup is 485 degrees celsius for APU operation ?

Explanation

The given statement is false. The maximum EGT (Exhaust Gas Temperature) during APU (Auxiliary Power Unit) startup is not 485 degrees Celsius for APU operation. The actual maximum EGT during APU startup may vary depending on the specific aircraft and its operating conditions.

Submit
89. The select switch on the standby engine display should be rotated to what position for PREPARATION of engine run?

Explanation

The select switch on the standby engine display should be rotated to the N2 position for PREPARATION of engine run. This is because N2 represents the rotational speed of the high-pressure compressor, which is an important parameter to monitor and control during engine start and run. By selecting the N2 position, the pilot can ensure that the engine is properly prepared and ready for operation.

Submit
90. When ambient temperature is below -30 A*C allow engine speed to stabalize for 30 seconds at what prior to adding fuel?

Explanation

The correct answer is "Maximum motoring speed." When the ambient temperature is below -30 A*C, it is important to allow the engine speed to stabilize for 30 seconds before adding fuel. This is done to ensure that the engine is running at its maximum motoring speed, which is the highest speed at which the engine can operate without the assistance of fuel. By allowing the engine speed to stabilize before adding fuel, it helps to prevent any potential damage or issues that may arise from starting the engine at a higher speed.

Submit
91. What is the power-setting limit for operating an engine with fan reverser ducts held open?

Explanation

The power-setting limit for operating an engine with fan reverser ducts held open is 2 Idle Power. This means that the engine should be set to idle power, which is the lowest power setting, in order to operate with the fan reverser ducts open. This is likely because the fan reverser ducts create a significant amount of drag, so operating the engine at a higher power setting could cause excessive strain on the engine and potentially damage it.

Submit
92. An automatic shutdown occurs when the APU RPM exceeds ___________.

Explanation

An automatic shutdown occurs when the APU RPM exceeds 104%. This means that if the RPM of the APU (Auxiliary Power Unit) goes beyond 104%, a shutdown mechanism is triggered. This safety measure is in place to prevent any potential damage or malfunction that may occur if the RPM goes too high.

Submit
93. The target for reaching an idle N2 state is_______ Seconds.

Explanation

The target for reaching an idle N2 state is 120 seconds.

Submit
94. What is the minimum amount of oil pressure that must be indicated any time the engine is running?

Explanation

The minimum amount of oil pressure that must be indicated any time the engine is running is 70 psi. This means that the oil pressure should not drop below 70 pounds per square inch in order to ensure proper lubrication and functioning of the engine. Maintaining adequate oil pressure is crucial for preventing engine damage and ensuring optimal performance.

Submit
95. What is the N1 maximum compressor speed?

Explanation

The N1 maximum compressor speed refers to the maximum speed at which the compressor of an engine can rotate. In this case, the correct answer is 100.5%, which means that the compressor can rotate at a maximum speed of 100.5% of its normal operating speed. This indicates that the compressor can operate at a slightly higher speed than its normal operating speed, allowing for increased air intake and potentially higher engine performance.

Submit
96. With in how meny seconds must N1 indication occur after the starter light comes on?

Explanation

N1 indication refers to the measurement of the rotational speed of the low-pressure compressor in an aircraft engine. After the starter light comes on, the N1 indication should occur within 90 seconds. This indicates that the engine is starting up properly and the low-pressure compressor is functioning correctly. If the N1 indication takes longer than 90 seconds to appear, it may indicate a problem with the engine startup process.

Submit
97. Prior to APU start, the APU Start Control Switch is positioned to run, and RPM is indicated: Personnelnshall position Start Control Switch to ? 

Explanation

The correct answer is "OFF" because prior to starting the APU, the APU Start Control Switch should be positioned to the "OFF" position. This ensures that the APU is not accidentally started during the pre-start procedures.

Submit
98. Within how many minutes after an emergency shutdown must an engine be restarted in order to prevent damage?

Explanation

An engine must be restarted within 15 minutes after an emergency shutdown in order to prevent damage. This is because prolonged shutdown can cause the engine components to cool down rapidly, leading to contraction and potential damage. Restarting the engine within the recommended time frame allows the components to maintain their operating temperature and prevent any adverse effects.
