(Precision approach path indicator). These are 4 lights in a row at the end of the runway. If they show 4 white you are too high, 4 red and you are too low. 2 white and 2 red you are at the correct height. Try to keep them 2 and 2 all the way down.

stinger2k2 Posted September 23, 2020 Share Posted September 23, 2020 I should also say that the approach is around 300ft per minute on your glide slope indicator. Sent from my SM-G935F using Tapatalk Link to comment Share on other sites More sharing options...

plainsman Posted September 23, 2020 Share Posted September 23, 2020 Also, particularly with jets and airliners, when you generate a flight plan, many programs will calculate top of descent, which will appear on the plan, and should show as a dot on the magenta flight path.

BushPilot Posted September 23, 2020 Share Posted September 23, 2020 (edited) For General Aviation Aircraft use this simple rule. Say you are at 5000ft Mean Sea Level and the Airport you are trying to land at is 800ft Mean Sea Level then: 5000ft - 800ft = 4200ft Then 4200ft x 3 = 12,600ft Then 12,600ft / 1000 = 12.6 You begin to Descent 12.6 Nautical Miles out. Generally - POWER IDLE and trim the air plane to 90 knots and you should get a nice 500ft / minute Play around with this and you will find what works best and you will nail it every time.

Kapitan Posted September 23, 2020 Share Posted September 23, 2020 If its Cub or small GA and a non-ATC airport calculate to be at 1000FT in Initial leg descending to 500ft, be at 500ft on base, maintain visual from runway and get into final at about half a mile, throttle to idle, flaps, carb heat if needed and glide to the runway :) Kapitan Anything I say is...not as serious as you think Link to comment Share on other sites More sharing options...
