Hi,

I would pickup answer b. Airbus recommends flap full landing to minimize the negative effects of a low flap setting, such as reduced tailstrike margins or higher approach speeds. But there are cases, as you can see, where flap 3 is the best option, when you need to maximize aircraft energy during approach such as in windshear operations. Beside all that, there are "also" fuel policy
issues. Flap 3 is a good option on a dry long runway where you can use idle reverse and autobrake low. The runway length depends obviously on your type and gross weight, and airlines usually give a reference value based on your airplane and operations.

better make flapless landing :) less drag, less fuel burn, makes all the beancounters in their offices happy .....and disregard good airmanship, which usually will use flaps full as "normal" setting for landing

ok :cool: honestly I use 99.9 % FLAPS FULL for normal landing

GENERAL CONSIDERATIONS

AIRBUS FCOM RECOMMENDATION

CONF FULL - MAX REVERSE THRUST

MAXIMIZE SAFETY MARGINS


page 3 ppt

for economics, airlines could envisage:

- Approach in CONF 3

- idle or no reverse thrust on landing


page 26 ppt

CONCLUSION

AIRBUS RECOMMENDATION IS:

TO MAXIMIZE SAFETY MARGINS IN NORMAL OPERATION, AIRBUS SOP STILL RECOMMENDS APPROACH IN CONF FULL AND TO USE MAX THRUST REVERSE FOR LANDING

sorry guys, that just an extract, as I am not able to bring the entire AIRBUS powerpoint presentation into pprune :confused:
