What else does TR3 do?
- any answers yet, Speedwinner?
2.) How long can the speedbrake be deployed. I mean with which flap setting? up to flaps 15?
No limit but best not more than F5 due to tailplane buffet - don't want it falling off, do we?
Not recommended more than flap five due increased roll sensitivity.
That's a new one for me! Boeing say no limit but 'should' be avoided at F15+. Nothing about roll - any reference for that?
3.)Where in the MEL can I find wether i have to have the athr engaged during the CAT III or not?
Not in MEL - in your AWOPS limitations section - A/T mandatory IF AVALABLE.
Under the MEL for the autothrottle, I would think. Autoland with manual throttle permitted in my company.
- not in any MEL I have seen. OM AWOPS limits - where is it in yours, Speedwinner?
