SimonK,
The policy is summarised on the BGS website here;
ATPL Distance Learning for Qualified Military Pilots | Bristol Groundschool
To quote the website;
"In the case of military pilots, QMPs with more 70 hours PIC/PICUS/P1 and an unrestricted Green Instrument Rating are exempt any training requirement before the IR test is attempted, although some training would still be considered wise."
Looks like you're enjoying the new job fella....
