I suggest adding Ground Proximity Warning System (GPWS) as following (when/where available): 2,500 feet, 2,000 feet, 1,500 feet, 1,000 feet, 500 feet, 400 feet (Approaching Minimums), 300 feet (Minimums), 200 feet, 100 feet, 90, 80, 70, 60 (if 90-60 is usable, mostly on Airbus), 50, 40, 30, 20, 10 and 5 feet (plus add "Retard" on Airbus planes when available).
Thanks.
