GPS signal
Hi Sham
I have always found BA very good about hand held GPS rx. Like you, I always ask the CC when boarding if they will ask the Capt, and have never had a problem.
I have a Garmin III and find it works fine just sitting on the table in front of me when in a window seat, I don't even have to hold it up to the window - I have not tried in an aisle seat. If I sit on the aisle, it is because I am more interested in the drinks trolley on that particular flight.
I always try and be discreet, not because I think I will be thought a terrorist, but I don't want to appear a GPS geek, although I am really!
