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 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
