Standard rate turn bank angle varies with speed. It is particularly useful as a means of cross-checking or confirming the validity of information being displayed by aircraft navigation systems and flight management systems. According to the Cessna P manual, a takeoff at sea level with standard conditions would require a roll of feet.
It is always useful to check mentally that loading figures make sense. Many a headache has been caused by the stress over how much crosswind component exists for a particular flight.
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.
