If an aircraft is flying (with flaps and landing gear retracted) in proximity to terrain and its GPWS (Ground Proximity Warning System) get activated, because it is detecting that the aeroplane has an excessive rate of descent, the system provides the following aural warning signals:

1) If an aircraft is flying (with flaps and landing gear retracted) in proximity to terrain and its GPWS (Ground Proximity Warning System) get activated, because it is detecting that the aeroplane has an excessive rate of descent, the system provides the following aural warning signals:

2) If the GPWS (Ground Proximity Warning System) activates, and alerts the pilot with an aural warning "DON'T SINK" (twice times), it is because:

3) The GPWS (Ground Proximity Warning System) releases a warning in the following cases:1. excessive rate of descent2. excessive ground proximity rate3. loss of altitude after take-off or go-around4. abnormal gear/flaps configuration5. excessive deviation under the glidepath6. abnormal airbrakes configurationThe combination regrouping all the correct statements is:

4) The GPWS calculator is able to operate in the following modes:1. excessive descent rate 2. excessive rate of terrain closure3. excessive angle of attack4. too high descent attitude 5. loss of altitude after take-off6. abnormal gear/flaps configuration7. excessive glidepath deviationThe combination regrouping all the correct statements is:

5) The GPWS calculator receives the following signals:1. vertical speed2. radio altimeter height3. pressure altitude4. glidepath deviation 5. gear and flaps position6. flight path angleThe combination regrouping all the correct statements is:
