There are no Katana's in INV there was one plane which never moved until it disappeared.
Staying completely away from the Schools at various places I will make a few comments about the WX in scotland based on 2 years VFR flying up here.
Inverness
Moray Firth has a micro climate which lends its self to good VFR training 15-20 knot winds are not uncommon but it never seemed to bother the students as they didn't know any different and it wasn't uncommon to send students solo in those conditions. Good viz (20k-45k) is the norm you can see Wick from the circuit on CAVOK days.
Perth
Can be good but suffered from low cloud and !!!!e viz at times microlights can be a right pain in the arse. And weekends in the summer you need your wits about you flying anywhere near the circuit.
Dundee
Suffers from sea fog certain times of year and low cloud.
Fife
Similar to Dundee apart from its in Fife and a bit higher and can get effects coming in from the Forth.
Aberdeen
Can be very windy and sea fog and low cloud are common.
Glasgow
Can't comment never had a big enough wallet to land there.
Edi.
Similar to all the East coast airfields low cloud, sea fog and strong winds which can last for days.
Wick
Can be bloody horrible strong winds low clouds. When it nice it very nice but when its horrible its very bad. Only advantage is that most of the wx only lasts a day or 2 then it changes again.
Prestwick
Similar to the Moray Firth local micro climate can allow you to fly when everywhere else in the region is closed for VFR training.
Cum
WX similar to Perth but with worse viz. Nothing wrong with the runway size or shape.
If your wanting to do a intensive PPL, Inverness is proberly your best bet (July and August is best). All the exams studied for, 3 weeks is do able.
And remember there is nothing stopping you chopping and changing schools. ie up to circuit level in one school while studying for the exams then changing to complete the circuit and x-country lessons. What ever the school says training records are transferable. I have had several "transfers" when getting the records has been some what of a trial, but after the threat of the CAA it all sorted its self out. But after seeing the student records I could see why they didn't want another school looking at them.
