I visited the guys at Scottish Information last weekend and would highly recommend it to everyone!
They're really friendly, very enthusiastic and eager to explain what they do and tell all about the information they can give us while airborne. It's definitely worth a visit, so that you can appreciate just what goes on at Prestwick House, and how much they have to deal with. They give an excellent service and are keen to do as much as they can to help PPLs as well as the professionals.
D & D are based there too, and if you want you can get to see what goes on in there too.
It's definitely encouraged me to speak to them more when I'm flying.
Get in touch with Fisbangwallop and ask for a visit. That's what I did, and he was only too pleased to help.
