An " altitude warning system" must at least warn the crew:

  1. when approaching the pre-selected altitude
  2. when the airplane is approaching the ground too fast
  3. in case of a given deviation above or below the pre-selected altitude (at least by an aural warning)
  4. in case of excessive vertical speed
  5. when approaching the ground with the gear retracted
The combination regrouping all the correct statements is:

2, 4, 5.
1, 2, 3, 4, 5.
1, 3.
1, 3, 4.
