The other thing to watch out for is taking off from a high airfield underneath airspace with QFE set. Crosland Moor at Huddersfield is a good one for that, there's class A at 3,500 and class D at 3,000. Field is at 800 odd feet, easy to forget on the climb out, seen it happen.
The answer to this problem is to discontinue use of QFE, as previously discussed in
this thread.
Which is why I would prefer, in the case of QNE to not bother with the added calculation of QFE. That way a single QNH derived alt reading would do for anywhere & the pilot can add elevation as required.
