Thunderstorms in missed approach path
 

Question for you experienced types out there.....

If you have a thunderstorm cell on a pre-defined missed approach path but nothing on the actual approach itself, would it be permissable to go for landing knowing that if you had to do a missed approach you would end up very close to or under an active cell?

The reason I ask is I see major airports have pre defined missed approach procedures, can these be altered suddenly if you actually had to go around to avoid weather, or are they set in stone?

Personally

(1) I would tell ATC (it they didn't know) of the CB cell in the go-around track,
(2) I would negotiate with them what I would do in the event of a go-around and what would be acceptable to them, this would obviously be subject to terrain,
(3) If that required an early turn before the threshold, then I would advise them of the need for landing clearance at x nm,
(4) If all of the above agreed I would be prepared to continue the approach and land.

As a rider to all the above, I would consider fuel state and the general weather pattern and the speed of movement of the cells. If delaying the approach for 10-15 minutes would 'solve' the problem, then I would also have that option.

To answer your questions,
'Is it permissable?' YES
'Can the G/A procedures be altered?' YES

This hapened one stormy night going into LHR about 10 years ago. The go-around on 09L east of LHR was too covered in red radar returns to contemplate. We simply asked in the event of a go-around, would it be permissable to carry out an immediate left turn- ATC will happily co-operate or advise another preferential course of action.
