Instrument Approach Procedure Charts Rate Of Descent Table
| INSTRUMENT APPROACH PROCEDURE CHARTS RATE OF DESCENT TABLE (ft. per min.)
A rate of descent table is provided for use in planning and executing precision descents under known or approximate ground speed conditions. It will be especially useful for approaches when the localizer only is used for course guidance. A best speed, power, attitude combination can be programmed which will result in a stable glide rate and attitude favorable for executing a landing if minimums exist upon breakout. Care should always be exercised so that the minimum descent altitude and missed approach point are not exceeded. | |||||||||||
