View Full Version : 737 NG Landing Distances In the QRH
I would like to know if the distances in the QRH PI SECTION 12 for flap 30 or 40 are actual and also why the reference distance for the Non Normal Configuration case the numbers are small
eg: PI 12.4 ALL FLAPS UP REF DIST 1225 M FOR 60000KG ( What corrections should be made to get actual figures for use )
New on the aircraft.
Havent seen the 737 QRH, but generally the QRH values are the actual landing distances without any additions. They are intended for use during flight when the 60/40 rule doesnt apply.

Figures in the QRH are max performance stops, based amongst other things literally standing on the brakes! Thought should be given to using a runway that includes a buffer above the QRH figure. For ease of brain power I just used to double the figure which would allow most failures on most runways.

Remember the QRH Normanl Configuration Landing Distances are calculated to STOP.
So, if you are planning and briefing to take a high speed exit from the runway you may in fact pull up short of the exit with no intervention. This is a common misunderstanding on the line.
If you are landing on the spot, on speed you may need less autobrake than you think if using a rapid exit. Experience on the line will help fill in the gaps for sure.
