Q

When is the Ground Proximity Warning System (GPWS) active?

A

The GPWS is embedded in the T2CAS system (Terrain and Traffic Collision Avoidance system) and generates aural and visual warnings between radio altitudes 10 and 2450ft.

Q

How does the BACK UP TUNING work?

A

If both FMGCs fail the flight crew can use the Radio Management Panels RMP 1 and 2 on the pedestal for back up tuning. The CAPT RMP controls VOR 1 and ADF 1 the F/O RMP controls VOR 2 and ADF 2.

Q

How many parts does each Air Data and Inertial Reference System (ADIRS) have?

A

Each ADIRU is divided in two parts either of which can work separately in case of failure in the other: The ADR part which supplies barometric altitude airspeed mach angle of attack temperature and overspeed warnings. The IR part which supplies attitude flight pathvector track heading accelerations angular rates ground speed and aircraft position.

Q

How does the Predictive Windshear System (PWS) operate?

A

The system scans the airspace within a range of 5 NM ahead of the aircraft for windshears. Below 1500 feet when the system detects a windshear depending on the range selected on teh ND a warning caution or advisory message appears on the ND. Predictive windshear warnings and cautions are associated with an aural warning.
