777 Landing

[DoMePlease]

For a comfortable 777 landing, what is the RATE OF DESCENT around the 20 feet to 10 feet auto callout?

If you're looking at the IVSI at the 20 foot point you're in BIG trouble.

In practice, the rate of call-out of 30, 20, and 10 feet is my best guide to a good landing. It works for me.

Assuming that the time between 30-20-10 callouts are in the region of 1 second, that would lead to a 600fpm descent.

(10ft -> 1 sec, so
?ft -> 60 sec (1 minute)

?ft = 10*60 = 600fpm.

You should, however, expect the rate of descent to decrease to about 300fpm during the flare.

Wind, gradient etc ignored, a good 777 landing can be very mechanical.
When u hear '30' feet rad alt, check back 2° pitch at a rate of 1° per second, and close the T/L's either as you hear 10ft, or as you feel your approach flatten out over the runway.
While I accept that this method does not for one second promise a 'gresser' everytime, it will at least give you safe consistent landings to progress from...
