FUJI.....
That was a pointless comment. Why did you make it?
To highlight the stupidity of your comment.
Have a word with the CAA old chap - they have thought otherwise for the last 40 years. Be in no doubt with an IMCr you are qualified to fly on instruments
It's no where near as comprehesive as an IR no matter how you look at it otherwise why do we have 2 seperate ratings

...period.
You raised the issue of cost, no one else
Wrong... You said:
40 years service with excellent safety record in an enviroment in which the CAA / JAA IR have proved practically unobtainable by most private pilots
If you refering to an average PPL's ability not budget to pass an IR then you have answered for me.
If you really had both I doubt you would make that comment
Don't insult me, it's certainly clear you don't have either!....Just two of many........Ask any American IR instructor how many times they fly a proc. NDB, then ask any UK IR instructor to fly an ILS backcourse.
Look......... I hope you enjoy safe flying in the UK and VFR abroad but I don't need to present you with any proof! It is NOT a recognised qualification outside the UK, get over it.......GET AN IR if you want IR privilages! There is a huge difference between them, sorry old chap!
