If the gear system had been doing what it is expected to do, this=20 distraction at a critical time would not be neecessary.

If this happens during takeoff, gravity is of no help and a landing = to=20 correct the problem is required.

Bill,

While one could expect the gear to not come down, there are = many=20 imbalances while the gear is up - gravity and the nose gear gas = spring=20 come to mind - this should relieve the pressure as soon as the = dump valve=20 is selected.

On the other hand, the gear down and locked is in a very = stable=20 condition - so one should only need such a switch for gear=20 retraction.
