Should be attained by a gross height of feet.

Considering this premise, rule No. The speed at which the aircraft's nosewheel leaves the ground. Distance to Initiate Descent Distant to descend divided by knock off zeros and multiply by three will give distance. They can, however, help pilots understand the influences of different performance factors on their aircraft, which should, by default, help augment safety.

With that said, there are many excellent rules of thumb out there. These are the stalling speeds for the aircraft at its maximum weight.

The rate of descent is based on indicated airspeed. Divide ias by two and add a zero.

Modern, more efficient aircraft, will need greater distances but similar rules of thumb can often be defined from a review of performance figures and line experience. It is the decision speed nominated by the pilot which satisfies all safety rules, and above which the takeoff will continue even if an engine fails. If you have any other rules of thumb that you find useful then please send the information to the Editor.

Other V-speeds Some of these V-speeds are specific to particular types of aircraft and are not defined by regulations. Distance to Descend Two times the ground speed in miles-per-minute times the altitude to lose in thousands of feet. This is the maximum speed at which it is safe to fly a retractable gear aircraft with the landing gear extended.
