Is it possible to reprogram Altitude Hold disconnect without affecting Vertical Speed Hold? At present IF Altitude Hold is disconnected, so is Vertical Speed which allows the aircraft to default to trim and again we have CAT for the passengers.
Maybe in the future the devs will be able to do that. For now, using the trim avoids at some point the nose dives (though the A320 family doesn’t have that).
Well atl and vs are unrelated. You can use vertical speed with out using alt. Sunce alt is to keep to plane at that altitude. Its supposed to be alt hold and you it should automatically turn on once you reach your altitude but is doesnt so that yet.
