Unless you have a concessionary rate agreed with the Glasgow Flying Club for the £15 quid a go then the fees will be based on a C150 type aeroplane :
£20 plus VAT Departure fee
£10 plus VAT CAA Nav fee
£40 plus VAT Handling fee
and yes PPR is required, mate I trained in the US also and got really used to those free landing fees but unfortunately not like that over here.
Hope that helps
