Thanks for the input: Simply putting the suit on by the aeroplane is a good shout. Alternatively and as suggested, I could consider a more subtle (though expensive) approach:
Lower:
Pioner Nomex Comfort Flame Resistant Cargo Trousers from Greenham [www.greenham.com]
Upper:
Alpinestars Nomex Top - Demon Tweeks
Interesting post from Genghis that leather does a similar job. Therefore:
RAF Leather Flying Gloves
BPF: All emergency checks are committed to memory. PFLs practiced every 6 weeks or so. So are diversions. I do not practice spin recovery however (that is a separate thread).
I must admit, the design of the PA28 access hatch (singular) leaves a lot to be desired...
