Airbus Procedures
Gentlemen
I have a few questions for the airbus guys. Hope you can shed some light. All questions are for the A330 or A 340
1. During the ramp check should the engine fire test button be pressed and held until you cancel the CRC 4 times (A340 or twice for the A330).If you here the fire bell once is it good enough. Do all fire detection systems on all engines get tested if you get all indications and hear the bell only once?
2. When inserting winds into the cruise page on the MCDU FCOM 4 states only insert winds if the change is greater than 30kts or 30 deg or temp 5 deg change. However there is a ambiguity where if you are cruising at e.g. FL 350 winds for that level need not be entered since the FMGC calculates actual winds 200 nm ahead to update the estimates. You should enter winds for levels above and below FL350?
3. Why is it not correct to enter the cruise temp in the fuel prediction page or the cruise level on the progress page in (ATL CRZ mode ) on the MCDU? Normally you see four dash lines where the temp is auto up dated.
Any help is welcome and if anyone can give any airbus references it would be better.
Thanks,
Sing 330
