I live on the Glasgow airport flight path and when a plane lands I lose signal quality, so that I have no picture for two or four seconds. Seems to only happen on BBCB transmissions. Any ideas what I can do?

We are going to need a full postcode to look at predicted reception at your location before we can offer any constructive advice.

Hmm, tricky one. According to the DigitalUK checker for your postcode, see About us | Freeview reception of the BBCB multiplex is excellent. Are you not getting any issues with other HD channels on the COMs 7&8 muxes?
Whether slight repositioning of the aerial may help is difficult to say, if you can check that it's pointing at 106deg. (16deg. S of E) - borrow a compass? Whether tilting it slightly up may help, or just alter the problem to just before they touch-down again is almost impossible to say. If you can easily and safely get to your aerial, experimenting is really the option.

Chris I now seem to have BBCB on 530.005 MHz, this was previously 626.000 MHz. Still have the same issue. Not able to reposition aerial. Any thoughts as to why?

You have BBCB on 530MHz which is UHF28 because you are picking it up from Darvel and it's lower power than Black Hill as well as further away, this will not be helping.
What wasn't clear is how long you've had the problem, if it's just since a retune in/since September when only the Local mux moved, then you've been unlucky.
It's also possible your aerial is not pointing in quite the direction it should be, although the beam-width may be sufficient to allow sufficient reception from Darvel. Can you not at least check the angle your aerial is pointing?
It should be 16deg. S of E (106deg) for Black Hill. Darvel is 178deg. almost due S.
I suggest that you unplug the aerial and do an automatic tune - this should clear all previous tuning as no signals are being received. Then plug the aerial back in and do a manual tune for each of the UHF channels from Black Hill. You should see channels from the coverage checker, but for clarity they are - Ch.no:(MHz) -
46 (674), 43 (650), 40 (626), 41+ (634.167), 44 (658), 47 (682), 55 (746), 56 (754), 30 (546) in the order
PSB1/BBCA, PSB2/D3&4, PSB3/BBCB, COM4/SDN, COM5/ArqA, COM6/ArqB, COM7, COM8, Local.

Hi Chris, I've checked alignment and it is same as others in the street , approx 106, it could be 103, would that have an influence? Magnetic of course.

That minor difference is unlikely to make much difference. But once you are tuned to the correct transmitter, as I'd said previously, it may be a case of experimenting and if you can't get to your aerial easily, it's difficult to say what might be best.
From your location, what direction is the runway in and where they touch down?
Do any of your neighbours get a similar problem?
