'Cos I'm ignorant, what is the CoPiLoT check?
While the Tommy checks are entertaining for cat lovers, they leave out a few points which could catch you out on an aircraft with dual magnetos, a primer and flaps. If you use TTMMPPFFGGHH, you should cover everything. I then add PLC, for Pitot heat as needed, Lights (strobes, nav lights...), Controls - full and free.
Never found a mnemonic for it all, though......
