Pressure Altitude Question
I came across a question from the questions listed by previous candidates that I couldn't answer. I was wondering if anyone could lend a hand with this one:
" If we are at 3000' and the QNH is 990, what is the pressure altitude?"
From what I've read, altitude increases 27ft every 1 mb. So, would this simply be (1013.25 - 990) x 27 +3000 = QNE = 3627.73 ?
The difference between the pressure altitude and the actual altitude seems to be a little on the high side.
Thanks for help.

Given the low altitude that answer would be ok in an interview situation with no aids. In reality the number you got is a little on the low side. The conversion changes with altitude:
1 mb = 27 feet at sea level
1 mb = 50 feet at 18000 feet
1 mb = 100 feet at 39000 feet
Correct answer would be 3640.7 feet using the real formula.
h2 - h1 = 221.1T (logP1 -logP2)

April AKL
Hey everyone, wow this is a long forum to read. Anyone going to the April interview in Auckland? I'm hoping to nail it to get out of this disaster zone we call Christchurch. Any tips would be greatly appreciated, especially these sample questions! Keep em coming!

No medical only in Stage 3 in HK.Although you will get a medical form to fillout and list any injuries or defects you may have. Be wary of this because if there is something on there that they dont like, you wont be invited back for Stage 2 even if you ace the whole thing.

773 and 77W
Hey James,
Here's my input into the forum in return maybe someone can help me.
747-400 uses either the RR (Rolls Royce) Rb211 or the PW4056 (Pratt and Whitney)
777-300 uses the RR Trent 892
777-300ER uses GE90-115B's
777-200's use RR Trent 877's
A340's use CFM56's
A330's use RR Trent 772's
One word of advice- Wikipedia.
Now as for everyone else, can someone please point out how would I identify the difference between a 777-300 and 777-300ER as they are the same length etc. Only difference I can think of is slightly bigger wings and bigger engines on the ER but how would you know if only one model is on the table...
Come to think of it, how does the -200 differ, (33.3ft smaller?) Should I count doors or something?
Cheers

greatbattle, i can't see anything wrong with your calculation other than you have used a rounded figure of 30ft per 1mb (which is used for simplicity) 
chchflyboy
if you think about what makes the 300ER wings longer, then u will be able to spot the difference
as for the difference between 200 and 300, counting the doors is a very easy way to tell, and if you look at enough pictures of the 200 and 300, you will see the difference clear enough

Hey guys,
Quick question! I got an interview on april 14th in San Fran. Since I don't have 1000tt and haven't done ATP written, I applied (in Nov 2010) for the cadet program. But this is what I recieved: "Cathay Pacific Airways is pleased to invite you to attend our Second Officer Initial Selection in San Francisco"
So, is this going to be a cadet or s/o interview? I'm confused.
Thanks

Hi guys,
What are the GCSE requirements? I have a C in science and a D in maths. Does this mean I'm not eligible? A few months ago I knew nothing about flying but taught myself using microsoft flight simulator, well followed the lessons and I have learnt a lot since and absolutely love it. Got a real flight coming up soon as I know real flying is a lot different from simulator flying.
Thanks.
