I guess I just read correctly into the question rather than interpreting it to literally. I guess sometimes it pays to have an open mind.

I'm coming around to the view this is a wind up. But just on the off-chance you really didn't know, bose-x, density altitude is pressure altitude corrected for non-standard temperature. Oh, BTW, density altitude is what we use in performance calculations ... so performance calculations require the input of pressure altitude ... oh, WTF

Indeed but the question was not around performance it was a pretty simple question that it seems had a typo in it. Thanks for the condescending lecture though.

I just applied logic to see around the typo it appears some were unable to.

:rolleyes:

In instructor parlance we call that statement "a justification" :}

Just out of interest, how come the logic you applied to 'see around the typo' got you a different answer to their's (which was 338ft)?:D

Only asking, as they say. ;)

As you observed, it was a pretty simple question ... so the inability of an instructor to distinguish between QFE and QNH seems rather fundamental, especially after the error he was making had been pointed out on several occasions.

I got the same answer as them and gave the correct math for the problem. Perhaps I read the question in the right context rather than looking at it dogmatically. So I would probably say it is the ability of an Instructor to look at the big picture...

However as my teenagers say - 'whatever'......

Ermm, no. As DaveD said in response to your answer:

PPLQUIZ said 338 was the right answer http://static.pprune.org/images/smilies/wbored.gif http://static.pprune.org/images/smilies/wbored.gif http://static.pprune.org/images/smilies/wbored.gif

Not what he says below:

But like I said whatever, we will have to agree to disagree.

Thank you for your email.

You are correct, the question has now been changed to read:

An aerodrome elevation is 968ft and the QNH is 992mb, what is the
aerodrome pressure altitude? (1mb = 30ft).

With the answer being 1598ft

30 x 21 = 630ft

The QNH is lower than 1013 so you have to wind the Altimeter up to get
to 1013 so:

968 + 630 = 1598ft

Hope this make sense.

Most of our questions come from student feedback, which you can enter

If in the future you do come across a question which you feel needed
challenging please use the ID box on the top right hand side so we can
locate the question easier.

Kind regards

ATC: ”B-OX, descend and maintain 3000 feet, QFE 995”

B-OX: ”3000 ft, QFE 995, B-OX”

(Thinking: Hey, QFE? They always give QNH around here… and I have an open mind, so I’ll just correct that without pointing out their obvious mistake, without declaring my own assumption and without interpreting things too literally. Lesse… they want me 3000 feet above AD elevation, and the AD is at 1400 feet. Allright, here we go, level off at 4400 feet. Man I’m on top of things!)

AAIB: ”A Piper PA28 and a B737 collided after a private pilot with an open mind failed to comply with ATC instructions in a non-radar environment. Five crew members and 78 passengers onboard the B737 were killed, along with the open-minded private pilot.”

Literally is how we do things in this industry. It is a method of reaching old age which has been proven time and time again. If something does not make sense taken literally, we question it but do not, repeat, do not go off acting upon our own assumptions.

And if we mess up, we call the tower upon landing on the telephone number they kindly provided, apologize and admit our mistake. After all, we are all human and we all make mistakes. Trying to deny having made a mistake is generally not a good idea, especially if it is on record.

Oh god.....
