Descent planning 3 to 1 rule
WebDescent planning . Effective power management requires forethought when it's time to descend, particularly if we fly high-performance aircraft or we fly at higher altitudes. We have three primary objectives—minimize the risk of shock-cooling the engine, avoid an uncomfortably high descent rate, and arrive at our destination at a reasonable ... WebAn example of a typical jet descent-planning chart is depicted in Figure 4-2. Item 1 is the pressure altitude from which the descent begins; item 2 is the time required for the descent in minutes; item 3 is the amount of fuel consumed in pounds during descent to sea level; and item 4 is the distance covered in NM.

WebA general rule of thumb for initial IFR descent planning in jets is the 3 to 1 formula. This means that it takes 3 NM to descend 1,000 feet. If an airplane is at FL 310 and the approach gate or initial approach fix is at 6,000 feet, the initial descent requirement equals 25,000 feet (31,000–6,000). Takedown request
