A320 recurrente apa

What is the main air source for the air conditioning packs?. Electrical compressors. Engine or APU bleed air. Recirculation fans. External compressed air.

What is the function of the Mixing Unit?. To cool the air before entering the packs. To mix hot and cold air to maintain uniform temperature. To regulate the airflow in each zone. To control cabin humidity.

If one pack fails, what happens to temperature control?. The system switches to manual mode. The remaining pack supplies all conditioned air. The aircraft depressurizes. The system uses only recirculated air.

What happens if the sidestick is moved while the Autopilot is engaged?. Nothing, the Autopilot ignores the input. The Autopilot disconnects immediately and the aural warning sounds. The Autothrust disengages automatically. Speed brake extension.

What is the function of the Flight Augmentation Computers (FACs) within the Auto Flight system?. They control pitch law and elevator trim. They manage yaw damping and rudder travel limitation. They generate flight guidance commands. They process flight plan data.

Which component coordinates the relationship between Autothrust and Autopilot?. ELAC. FCU. FMGC. SEC.

Which system allows digital communication between the aircraft and maintenance/dispatch?. SELCAL. ACARS. CVR. ATC Transponder.

What happens if an Audio Management Unit (AMU) fails?. All VHF communication is lost. The other AMU takes partial control. ACPs stop working. VHF transceivers change frequency.

How does the pilot select the audio source for VHF transmission?. From the MCDU. From the Audio Control Panel (ACP). Automatically by priority. From the radio pedestal.

Under normal conditions, the engine-driven generators supply. Only the AC ESS BUS. All AC and DC buses. Only the DC ESS BUS. The emergency system.

If both generators fail, the essential buses are powered by. Batteries. RAT and Emergency Generator. GPU. APU Generator.

What is the function of the Static Inverter?. Converts AC to DC. Converts DC to AC for essential buses. Regulates generator frequency. Monitors electrical faults.

How does the engine fire detection system sense a fire condition?. Pressure differential. Optical flame sensors. Thermal detection loops. Airflow increase.

How many detection loops does each engine have?. One. Two (Loop A and Loop B). Three. Depends on the engine type.

What happens when the ENG FIRE pushbutton is pressed?. The engine shuts down immediately. Fuel, hydraulic and bleed valves close, and extinguisher is armed. Only the fire bottle discharges. The master warning activates.

Which system provides the control signals to primary flight surfaces?. Cable and pulley system. Electronic Fly-By-Wire. Direct hydraulic control. Pneumatic control.

What is the function of the ELAC?. Yaw control. Slat and flap control. Elevator and aileron control. Spoiler control.

What happens if both ELACs fail?. All flight controls are lost. SECs take over partially. Aircraft goes to manual mechanical mode. Only yaw control remains.

How many hydraulic systems does the A320 have?. One. Two. Three. Four.

What event causes automatic RAT extension?. Single generator failure. Dual AC BUS failure. Low Green system pressure. All hydraulic systems failed.

Which flight control uses all three hydraulic systems?. Flaps. Slats. Elevators. Spoilers.

Which system supplies air to the Wing Anti-Ice?. APU Bleed. Engine Bleed. Recirculation air. Electric compressors.

How are pitot probes and temperature sensors heated?. By hot air. By automatic electrical heating. By conditioned air. By windshield heating.

Which components are electrically heated for ice protection on the A320?. Wing leading edges and engine inlets. Windshields, probes, and TAT sensors. Slats and pitot probes only. Engine nacelles and tailplane.

What controls the landing gear extension/retraction sequence?. LGCIUs. ECAM. BSCU. FAC.

Which system allows emergency landing gear extension?. Electrical system. Pneumatic system. Manual mechanical system. Secondary hydraulic system.

What condition prevents landing gear retraction on ground?. Electrical failure. Ground spoilers extended. Ground signal active. Low hydraulic pressure.

What is the function of the ADIRU?. Manages communication with FMGC. Provides attitude, heading and air data. Controls pressurization. Calculates fuel flow.

If one IR fails, what happens?. Total navigation loss. Remaining IRs take over and ATT mode available. ECAM display lost. No effect.

Where is the IRS alignment initiated?. FMGC. FCU. MCDU. ECAM.

What does the Bleed Monitoring Computer (BMC) control?. Cabin temperature. Bleed regulation, closure and isolation. Fuel pressure. Oil temperature.

Which source can provide bleed air on ground with engines off?. APU. GPU. RAT. Batteries.

What happens during a BLEED LEAK condition?. System shuts down automatically. The duct is ventilated. BMC closes the affected valve. RAT deploys.

Which unit controls all automatic APU functions?. FADEC. ECB (Electronic Control Box). Starter Generator. FMGS.

Which conditions trigger an automatic APU shutdown?. High EGT. Low oil pressure. Overspeed. All of the above.

How can the APU supply pneumatic air in flight?. Only with engines off. Up to limited altitudes. At any altitude. It cannot be in flight.

Which component computes the thrust data and controls the engine operation in real time on Airbus A320 family aircraft?. EGT sensor. ECU. FADEC. EIU.

¿In the CFM 56 engine, what is the function of the Pylon drains?. Drains are provided at the pylon rear part to evacuate and vent overboard air and any residual fluid (water, hydraulic, fuel). The drain mast protrudes through the fan cowl doors into the airstream to evacuate any residual fluids. This corresponds to the drainage points from the blue hydraulic pump.

IN CFM 56 ENGINES, THE THRUST REVERSER SYSTEM CONSISTS OF. 4 pivoting blocker doors which stop and redirect fan discharge airflow. Two doors are installed on each side of the reverse unit. A and B are correct.

What conditions must be met successfully to start deploying the Thrust Reverser system on ground?. the EEC confirms the engine running idle before starting sequence and LGCIU confirms aircraft on ground. SEC receive (TLA < -3° AND RA <6 FT). TR stowed and locked and ICU/HCU not inhibit.
