Villas, agree with the wording for normal SOPs, and it’s the aim for the perfect profile.
However on my A319, the F2 selection is followed immediately by the following note...
If the aircraft speed is significantly higher than "F" speed on the flight path, or the aircraft does not decelerate on the flight path, extend the landing gear in order to slow down the aircraft. The use of speed brakes is not recommended.
no instructions to wait.
The normal “when flaps are at 2” is in the subsequent section.
But is there a
restriction /
limitation /
prohibition on putting the gear out when the flaps are travelling (eg “XXX, reduce to min approach speed immediately “)? (or vice versa) I can’t see hydraulics being a limitation, again, in a go around the gear is often coming up as the flaps are travelling up one stage.
