Couple of questions im having trouble with on Airbus tech exam!!!

[norton2005]

Hello all, I've been working through a tech paper for fun and experiance, and theres two questions that have me stumped and cannot find the answer,

1st one is, what should you do in the event of the EVAC horn sounding in flight?

a. remove the power to the cabin using the GALY & CAB pb on the overhead panel.

b. follow the ecam procedure for 'evac horn emitting'

c. it may be silenced via the evac horn off switch on the ground only.

d. a qrh procedure applies.

I didnt think it was d as i dont think i've ever seen a procedure like that in the qrh!! my initial inkling was c, but i ws unsure if you could only silence it if on the ground?

And the second one, was just one of those what is the total fuel flow per hour, under certain conditions, holding at FL100 in clean configuration at green dot etc etc, could anyone point me to the relevant graphs where I could do this? as cant find it so far!!!

Thankyou very much for any help you can give on this!!!!!

I think you'll find it in the Computer Reset Table in the QRH.

try FCOM 3.05.25.P2 for the holding question.

Thanks for the reference arba.
Interesting to note that the optimal level for minimum fuel burning while waiting seems to be around FL200 and not higher except maybe for the lighter weights.
