Agree with MJ, nice airfield, also has an ILS, NDB and lighting should you ever need it.
Plenty of space and places to go for sightseeing and Navexes in the Central belt as said before. Try a zone transit through PH and go down to the Borders if its a nice day and the cloudbase is decent, or go North, e.g. Pitlochry, Loch Tay etc. Also you'll need to fly down the length of the bonny banks of Loch Lomond.
A nice route is to follow the corridor between Edinburgh and Weegie past Falkirk, Motherwell and Strathaven (watch for the microlight strip there though) and pop in to Prestwick. Plenty nice Wx and scenery down there too.
