How far out should you start descending?


How far out should you start descending? A good rule of thumb for most jets would be: 3 miles for each 1,000 ft. of altitude to lose + 1 mile for every 10 KIAS of airspeed that you need to lose before landing. So in this case, we will start down 128 miles out.


What is the 3 to 1 rule for descent planning?

A 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).


Do pilots feel turbulence?

Turbulence from Convection Currents and Obstructions. Convection currents cause the bumpiness experienced by pilots flying at low altitudes in warmer weather. On a low flight over varying surfaces, the pilot will encounter updrafts over pavement or barren places and downdraft over vegetation and water.


What is the rule of thumb for aircraft descent?

Unsourced material may be challenged and removed. In aviation, the rule of three or 3:1 rule of descent is a rule of thumb that 3 nautical miles (5.6 km) of travel should be allowed for every 1,000 feet (300 m) of descent.


How do you know when to start descending?

A good rule of thumb is to allow yourself two minutes for each 1,000 feet of altitude you need to lose. So, if you're cruising at 10,000 feet above field elevation, start descending 20 minutes before your planned arrival.


How do you tell a pilot to have a good flight?
