QNH

Recommended Posts

Hi,I've been having a weird problem with the A330.On a flight from Melbourne (YMML) to Sydney (YSSY) having programmed all the data in the FMGS once in the climb through 10,000ft I get the QNH box flashing on the PFD as though I'm going through FL180.The weird thing is if I just take off without programming the FMGS, once through 10000ft I get no flashing QNH warning until 180.Is this a bug of some sort? Is there a fix?Thanks in advance,Rob

You can manually change the transition altitude by entering the altitude on the PERF page in the respective LSK line, when programing the MCDU at the gate.Michi

But do make sure you change it to the correct transition alt; it is shown on SID and STAR charts.
