Selecting REVERSE:Airbus

[Jumeirah James]

Does anyone know why we wait for the 'REV GREEN' to come on before REVERSE is selected please? Can't we just apply reverse and the FADEC govern when it can supply power? I asked an Instructor and all he said was 'it's SOP'.

Thanks for your replies

JJ,
Its not SOP in my company. However I would guess that your company wants to ensure all reversers unstowed before applying Max reverse. If one does not unstow and you apply max reverse you could get quite a large swing.

According to Airbus standard SOP 3.03.22 P5 REV33

you are supposed to select max reverse immediately after the main landing gear touches down.

Any other restrictions might be due to company policy or airport regulations...

Kind Regards

A330 - Wait for REV green

A320 - You don't

Please state the aircraft type!.

Your profile states Dubai...A330 I would guess????

Thanks for the replies Gents.

FYI, I'm on the A330 but soon to go onto the A340. The same applies there apparently too.

So would it be a fair assumption that this might be an Engine manufacturer related specification or purely performance related, as RWU suggests? As the A320 doesn't specify this, wouldn't you get a large swing too if it didn't deploy?

Thanks again

When you land a 320 OEI and apply max reverse, you don't get a big swing... I thing...k? I think there's an idle reverse limitation on the 321 though.

Idle reverse is permitted down to aircraft stop (A320,A321)

It depends on which engine you have. CFM is ok, but the V25 has a cascade reverser which can blow out the refueling panel door below 60 kts. Airbus have now modified newer aircraft refueling panel doors and they can be identified by the hinges being on the forward edge.

We have V2500's on our new A321's, no such restriction.
