A 320 Sys Pneumatic And Communications

If a BMC fails, the remaining BMC will automatically assume most of the fallen BMC's functions. This means that the functioning BMC will take over the tasks and responsibilities of the failed BMC in order to ensure the continued operation of the system. Additionally, it is stated that all systems associated with the failed BMC also fail, which further emphasizes the importance of the remaining BMC taking over its functions. The closure of the associated bleed valves is mentioned as a consequence of the BMC failure, indicating that the failure has an impact on the overall system.

When selecting the guarded RMP NAV key, FMGC auto tuning is inhibited. This means that the Flight Management and Guidance Computer (FMGC) will not automatically tune the navigation frequencies. However, manual tuning via the MCDU RAD NAV page is still possible, allowing the pilot to manually input and tune the desired frequencies for navigation.

The function of the guarded EMER push button on the overhead panel is to alert all flight attendants of a pending urgent need to speak to them. This button is used to quickly and effectively communicate important information or instructions to the flight attendants in case of an emergency or any urgent situation that requires their immediate attention.

The correct statement regarding the cockpit voice recorder is that it is automatically energized after the first engine start or five minutes after AC electrical power is applied to the aircraft. This means that the cockpit voice recorder will start recording either when the engines are started or after a certain period of time after the aircraft's electrical power is turned on.

When the APU is running and the APU BLEED pb is selected ON, and the X BLEED selector is set to AUTO, the APU will supply pneumatic air to both sides of the aircraft because the pneumatic crossbleed valve automatically opens. This means that bleed air will be available for use on both sides of the aircraft, ensuring that all systems are supplied with the necessary air pressure.

The crew has direct control over the bleed valves for the engine and APU crossbleed. This means they can open or close these valves as needed. The other mentioned bleed valves (engine intermediate pressure and crossbleed) may not be directly controlled by the crew, or they may not exist. Therefore, the correct answer is engine and APU crossbleed.

When a bleed leak is detected by a BMC (Bleed Monitoring Computer), all valves that have the capability to provide pneumatic air to the location of the leak will close automatically. This is done to prevent any further loss of air and to isolate the affected area. Additionally, the crew is required to isolate the specific leak to ensure proper containment and maintenance.

The correct answer is CAB because in aviation, the term "CAB" refers to the Cabin Attendant Panel, which is a control panel located in the cabin of an aircraft. This panel allows flight attendants to communicate with the cockpit crew by illuminating a specific key when they need to contact them. Therefore, if the flight attendants are calling the cockpit, the CAB key will illuminate.

When both engines are operating and an ENG BLEED pb FAULT light illuminates, it means that there is a fault with the valve position. The valve position is not in accordance with the position indicated by the push button. This indicates a discrepancy or malfunction in the valve control system, which needs to be addressed and corrected.

The correct answer is that APU bleed air has priority over engine bleed air. This means that when both sources are available, the aircraft will use bleed air from the APU instead of the engines. However, if the ENGINE BLEED pb's are selected OFF, the APU bleed air will be the only source of bleed air supply. Similarly, if the X BLEED selector is selected OPEN, the APU bleed air will also be the only source of bleed air supply.

When engine and wing anti ice are in use, and a DMC detects a bleed leak, the wing anti ice on the associated side will be lost, and the engine anti ice on the associated side will continue to function.

The correct answer is "Using an overhead FWD or AFT call push button." This is the appropriate way to call a flight attendant on an aircraft. The overhead call buttons are located in the forward (FWD) and aft sections of the cabin, allowing passengers to easily request assistance from the flight attendants.

ACARS stands for Aircraft Communications Addressing and Reporting System. It is a digital datalink system used for communication between aircraft and ground stations. The correct statement concerning ACARS is that it may be accessed through both the first officer's and captain's MCDUs (Multipurpose Control and Display Units). This means that both pilots have the capability to access and use the ACARS system for communication purposes.

Both A and B are correct because to make a PA announcement, you need to depress and hold the PA transmission key push button, as well as use the pedestal mounted handset. These two actions are necessary in order to activate and transmit the announcement through the PA system.

The correct answer is to select the transmission key push button labeled CAB and the audio selector labeled CAB. This is the appropriate action to take in order to communicate with a mechanic for manual start valve operation at the engine. By selecting these buttons, the communication system will be activated and allow for communication with the mechanic.

RMP 1 is dedicated to VHF radios, specifically VHF 1 and 3.

When the aircraft is in the Electrical Emergency Configuration, both RMP's (Radio Management Panels) 1 and 2 and ACP's (Audio Control Panels) 1 and 2 are operative. This means that all the radio management panels and audio control panels on the aircraft are functioning and can be used for communication purposes.

The correct answer is "Indicate a SELCALL." If the VHF 3 transmission key is illuminated amber showing the word CALL, it indicates that a SELCALL (selective calling) is being initiated. SELCALL is a method used to selectively call and communicate with specific individuals or groups on the aircraft's communication system. Therefore, the amber light and the word CALL indicate that there is a SELCALL message waiting to be received or responded to.

When an RMP is selected to a VHF system that it is not dedicated to, the white SEL (Select) light will be illuminated on both ARMPs (Audio Radio Management Panels). This is considered a normal occurrence during flight.

Both options A and B are correct for communication with other cockpit crew members while wearing the oxygen mask. Option A states that the ACP INT/RAD switch should be selected to INT, the INT reception knob should be turned on, and the loudspeaker should be turned up. Option B states that the INT transmission key should be used with the INT reception knob turned on, and the side stick push-to-talk button should be used when speaking, with the loudspeaker volume turned up. Both options mention the correct settings for the ACP switch and loudspeaker volume, ensuring effective communication with other crew members while wearing the oxygen mask.

When the pneumatic system pressure is lost, the engine bleed valve will assume the closed position. This is because the engine bleed valve is designed to open and allow bleed air from the engine to be used for various purposes, such as pressurizing the cabin or powering air conditioning systems. However, when the pneumatic system pressure is lost, there is no longer a source of bleed air, so the valve automatically closes to prevent any air leakage or loss.

When additional pneumatic air is required for anti-ice, engine starting, or air conditioning, the crew must observe minimum N1 limits. This means that they need to ensure that the engine's rotational speed, known as N1, does not fall below a certain threshold. Additionally, the BMC (Bleed Monitoring Computer) will request additional pneumatic air from the FADECs (Full Authority Digital Engine Control) or the APU (Auxiliary Power Unit). This ensures that the necessary amount of air is provided for the required functions. Therefore, both options A and B are correct.
