C-17a Engine Run Flash Cards

Person A gives the engine run team briefing prior to engine run. This indicates that Person A is responsible for providing important information and instructions to the team before starting the engine. They may cover topics such as safety precautions, procedures, and any specific details or issues related to the engine run.

To prepare for an engine run, all fire pull handles should be pushed in. This is because pulling them out would activate the fire suppression system, which is unnecessary and potentially dangerous when the engine is being started. By pushing the handles in, the fire suppression system remains inactive, allowing for a safe engine run without any accidental discharge of fire suppression agents.

To prepare for the engine run, all fire pull handles should be pushed in. This is because pulling them out or rotating them in any direction could potentially activate the fire suppression system, causing unnecessary discharge of fire suppressant agents. By pushing the handles in, they remain in a safe and secure position, ensuring that the fire suppression system is not accidentally triggered during the engine run preparation.

Person A should pull out the engine start switch if the switch does not disengage by 55% N2rpm. This means that if the switch is still engaged after the engine reaches 55% N2rpm, Person A should manually disengage the switch. Therefore, the statement is true.

It is important for Scanner person C to stay in full view of person A at all times during an engine run for safety reasons. This ensures that person A can closely monitor the engine and any potential hazards or issues that may arise. It also allows for quick communication and coordination between person A and person C in case any adjustments or actions need to be taken during the engine run. By staying in full view, person C can effectively assist person A and ensure a safe operation.

The correct answer is APU is primary, external pneumatic is secondary. The APU (Auxiliary Power Unit) is a small turbine engine located in the tail of the aircraft that provides electrical power and compressed air. It is commonly used to start the aircraft engines. The external pneumatic source refers to ground-based equipment that supplies compressed air to start the engines. While the APU is the primary air source for starting the engines, the external pneumatic source can be used as a secondary option if the APU is not available or not functioning properly.

The correct answer is the Pilot or co-pilot sliding window. Opening the sliding window prior to opening the crew entrance door after running engines ensures that the aircraft is not pressurized. This is because opening the sliding window allows for equalization of pressure between the inside and outside of the aircraft, preventing any potential hazards or difficulties in opening the crew entrance door.

Using both systems A and B alternately will prolong the life of ignition system components. This is because using only one system consistently can cause wear and tear on the components, while alternating between the two systems allows for more balanced usage and reduces the strain on the ignition system.

When the ambient temperature is below 0 degrees Celsius, it becomes necessary to facilitate the engine start. In such conditions, both the A and B ignition systems may be required. These ignition systems provide the necessary spark to ignite the fuel-air mixture in the engine cylinders, ensuring a successful start even in cold temperatures. The flux capacitor heater, battle start, and pressing all four start switches are not relevant in this context.

When the ambient temperature is below 6 degrees Celsius and there is rain, sleet, ice crystals, or fog with visibility of one mile or less, it is necessary to operate the engine with anti-ice. This is because these weather conditions can cause ice to accumulate on the engine, which can disrupt its performance and potentially lead to engine failure. Therefore, using anti-ice is essential to prevent ice formation and ensure the engine operates smoothly.

Person A has control over the throttles and fire pull handles at all times.

It is necessary to fasten seatbelts and shoulder harness for an above idle run to ensure the safety of the occupants in case of any sudden movements or emergencies. This helps to prevent injuries and keep the passengers secure during the run.

The APU Start Control Switch being spring loaded to the run position means that when the switch is released, it automatically returns to the run position. This design feature ensures that the APU (Auxiliary Power Unit) remains operational and continues to provide power to the aircraft systems. It eliminates the need for the pilot or operator to manually hold the switch in the run position, allowing for a more convenient and efficient operation of the APU.

If the number 3 Tank FWD boost pump switch light is not turned on within 2 minutes, it indicates a malfunction or failure in the system. This can result in a loss of fuel supply to the engine, potentially causing a loss of power or engine failure. Therefore, the APU WAP (Warning Advisory Panel) will display a caution to alert the pilot of the issue. Hence, the statement is true.

The cowl anti-ice system is responsible for preventing ice formation on the engine cowl during icing conditions. If this system is not available or malfunctioning, operating the engine could lead to ice accumulation on the cowl, which can disrupt the airflow and potentially damage the engine. Therefore, the engine must not be operated during icing conditions when the cowl anti-ice system is not available or malfunctioning.

The correct answer is "FWD IDLE." This means that all throttles should be in the forward idle position when preparing for an engine run. This is important for ensuring that the engines start and run properly. The other options mentioned, such as MAX and EPR OF THE DAY, are not the correct positions for engine preparation.

The correct answer is Person C visually checks the brakes. This means that the person physically inspects the brakes to ensure that they are properly set. This method of checking is reliable as it allows for a direct observation of the brake system, ensuring that they are functioning correctly and securely. The other options, such as the position of the handles, the pressure indicator reading, and the indication on the MFD, may provide additional information but cannot guarantee that the brakes are set.

It is not advisable for Person B to rest their feet on the brake pedal during engine run. This is because unintentional pressure on the brake pedal can cause the brakes to engage, leading to unnecessary wear and tear on the brake system. Additionally, it can also be a safety hazard as it may result in sudden braking or loss of control of the vehicle. Therefore, it is recommended to keep the feet away from the brake pedal unless it is necessary to use the brakes.

The operating range of the engine driven hydraulic pumps during engine operation is 3800-4200 psi.

Before performing the engine run, the aircraft must be positioned to meet the wind limits. This means that the aircraft should be positioned in a way that the wind conditions are within the acceptable limits for engine operation. This is important because excessive wind can affect the safety and efficiency of the engine run. Therefore, ensuring that the aircraft is positioned correctly in relation to the wind is a necessary criterion before proceeding with the engine run.

Person A must have control of the steering wheel while operating engines above idle because they are typically the driver or operator of the vehicle. As the person in control of the vehicle, it is their responsibility to steer and navigate the vehicle safely.

The correct answer is Two Minutes. This is because allowing the APU (Auxiliary Power Unit) to operate with no load for a minimum of two minutes prior to shut down helps to cool down the system and prevent any damage due to the sudden cessation of power. It allows the APU to gradually reduce its operating temperature and avoid any potential thermal stress.

The APU PWR Switch on the electrical panel needs to remain on until after the APU is completely shutdown. This is because the APU PWR Switch provides power to the APU, and turning it off before the APU is fully shutdown could cause damage or malfunctions. Therefore, it is necessary to keep the APU PWR Switch on until the APU is completely shutdown.

The personnel need to position the Start Control Switch to the run position for two seconds before starting the APU.

The correct answer is ANN/DIGT test switchlight. This switchlight is used to test all lights and digital indicators on the overhead panel. By pressing and holding this switchlight, the pilot can verify the functionality of all lights and digital indicators on the panel.

When the start control switch on the APU panel is set to start and released, the parameters that increase are the Exhaust Gas Temperature (EGT) and the Revolutions Per Minute (RPM). This is because when the APU is started, fuel flow increases, which in turn increases the EGT. The RPM also increases as the APU starts spinning faster. Therefore, the correct answer is Exhaust Gas Temperature and Revolutions Per Minute.

When the APU access doors are open, it means that there is a potential fire hazard in the APU (Auxiliary Power Unit) area. In such a scenario, the aircraft mounted fire extinguisher system alone may not be sufficient to extinguish the fire. This is because the open doors can allow more oxygen to enter the area, fueling the fire and making it harder to control. Therefore, it is true that when the APU access doors are open, the aircraft mounted fire extinguisher system may not be enough to extinguish a fire.

The Start Control Switch is responsible for causing the APU to shutdown when it is turned off. This switch controls the starting and stopping of the APU, so when it is put to the off position, it initiates the shutdown process.

Engines must be operated in symmetrical pairs above 75% N2 RPM. This means that both engines in an aircraft must be running at the same RPM (revolutions per minute) and this should be above 75% of the N2 RPM. This is important for maintaining balance and stability in the aircraft during flight. If the engines are not operated in symmetrical pairs, it can lead to uneven thrust and potentially affect the performance and safety of the aircraft. Therefore, the statement is true.

The correct answer is Inlet cushion pad. Inlet cushion pads are installed in the inlet for inspection of the intake prior to and after an engine run. These pads provide protection to the engine from foreign object damage (FOD) and help in preventing debris from entering the intake during inspection. They are designed to absorb the impact of any foreign objects that may be present in the intake, reducing the risk of damage to the engine.

When operating engines with open thrust reverser ducts (fan ducts), it is necessary to have both the left and right side accessory compartment doors installed and locked. This is important for safety reasons as it ensures that the compartment doors are securely in place and prevents any potential hazards or accidents that could occur if the doors were not properly installed.

The explanation for the given correct answer is that the auto shutdown override switchlight on the APU panel should be in the "True" position for a normal APU start. This means that the switchlight should be turned on to override any automatic shutdown commands and allow the APU to start and operate normally.

A HOT light and an automatic shutdown of the APU during normal operation indicate an overtemperature condition. This means that the temperature of the APU has exceeded its safe operating limits, triggering the shutdown mechanism to prevent any potential damage or safety hazards.

Radio communication between ground, cockpit, and controlling agency is essential for safe engine operation. This communication allows for coordination, monitoring, and control of the aircraft during various phases of flight. Without this communication, there is a risk of miscommunication, lack of situational awareness, and potential safety hazards. Therefore, it is crucial to have radio communication established before conducting engine operations.

If a start is aborted after lightoff, the engine must be motored until the Exhaust Gas Temperature (EGT) is below 190 A Degrees in order to prevent damage. This means that the engine should continue to run without any load until the EGT reaches a safe temperature. Running the engine without load helps to cool down the engine components and prevent any potential damage that could occur from the aborted start.

When there is evidence of fuel leaks in the pylon area, it is crucial to investigate the issue before running the engines. Running the engines without addressing the fuel leaks can lead to a potential fire or explosion. Investigating the cause of the fuel leaks ensures that any necessary repairs or maintenance can be carried out to prevent any further damage or safety risks.

Restricting movement during power runs is necessary for safety reasons. Power runs involve testing machinery or equipment at full power, which can be dangerous if there is unrestricted movement. Restricting movement helps to prevent accidents or injuries that could occur if someone accidentally comes into contact with the running equipment. Therefore, the correct answer is False.

The correct answer is that all answers are the scanner's responsibility. This means that the scanner is responsible for notifying person A of any vehicular or aircraft movement, keeping all personnel and equipment clear of the aircraft, and not allowing anyone to enter the aircraft without proper authorization. In other words, the scanner plays a crucial role in ensuring the safety and security of the aircraft and its surroundings during engine run.

The engine shutoff switch is used to shutoff engines. This switch is specifically designed to cut off the fuel supply or electrical power to the engine, effectively shutting it down. It is an important safety feature that allows for immediate engine shutdown in case of emergencies or when the engine needs to be turned off for maintenance or repairs. The ignition switch is responsible for starting the engine, the APU power switch controls the auxiliary power unit, and the fuel solenoid switch regulates the flow of fuel to the engine.

When an engine needs to be started within 30 minutes after it has been shut down, it is necessary to motor the engine until the Exhaust Gas Temperature (EGT) is below 190 degrees A. This temperature threshold ensures that the engine is cooled down sufficiently before starting it again, preventing any potential damage or issues that could arise from starting the engine when it is still too hot.

When the fire detection system loop A and loop B are both inoperative, it means that there is no functioning fire detection system in place. This poses a significant risk as there would be no way to detect and respond to any potential fires that may occur during the operation of the APU. Operating the APU under these conditions could lead to injuries to personnel and damage to equipment. Therefore, it is important to not operate the APU when both fire detection system loop A and loop B are inoperative.

A successful APU loop A and loop B test on the environmental panel is indicated by all of the above mentioned signs. This means that the APU loop A and loop B lights come on, the center master warning press to reset lights on the glare shield are activated, and the fire light on the APU panel comes on with the WAP display. These indications confirm that both loop A and loop B of the APU system are functioning properly.

In the event of an APU fire, there are three possible locations available to shutdown the APU.

The APU stabilized RPM refers to the range of rotational speeds at which the APU (Auxiliary Power Unit) remains stable. In this case, the correct answer is 97-101%, indicating that the APU's RPM should be maintained within this range for optimal performance and stability.

During normal APU operation, the APU off/arm switchlight is in the OFF/Raised position. This indicates that the APU is not in use and is turned off. The raised position of the switchlight means that it is not depressed or activated.

The DC X Tie should be in the "TIE" position when using the ground power cart or APU generator to power the electrical system. This means that the cross tie between the DC bus and the battery bus is closed, allowing power to flow between them. By keeping the tie in the "TIE" position, the electrical system can be powered efficiently and effectively.

The statement is true because it states that the idle N2% rpm target of 120 seconds may be exceeded under certain conditions. These conditions include ensuring that the starter limits are not exceeded, the N2 rpm is increasing, and there are no other out of limit conditions. This means that as long as these conditions are met, it is acceptable for the idle N2% rpm target to be exceeded beyond 120 seconds.

In the event of a fire, person (B) must notify ground control and provide the aircraft tail number. This is because ground control is responsible for managing and coordinating all ground operations, including emergency situations like fires. By notifying ground control, they can immediately take appropriate actions to address the fire and ensure the safety of personnel and the aircraft. Providing the aircraft tail number helps ground control identify the specific aircraft involved, allowing them to respond more effectively and efficiently.

The ground safety pin must be removed from the NLG steering bypass valve handle in preparation for engine run. This is because the NLG (Nose Landing Gear) steering bypass valve handle controls the steering system of the front landing gear. During engine run, it is necessary to have the steering system operational in order to maneuver the aircraft on the ground. Therefore, the ground safety pin needs to be removed from the NLG steering bypass valve handle to ensure that the steering system is enabled and ready for use.

If the starter duty cycle is exceeded in an attempt to extinguish a tailpipe fire, the starter may have been damaged or malfunctioned. Therefore, the best course of action would be to remove and replace the starter. This would ensure that the damaged or faulty starter is replaced with a new one, allowing for proper functioning of the starter system.
