thanks to andyy
for the backup, however a review of the IDP aircraft build standard states that civil variants will use the CT7 and Military will use the T700 (effectively the same engine), there is no mention of RTM322 in the EH101 development plan. It was added when 'Merlin' was specified as a modified IDP EH101 variant that used a 'legacy' (ie IDP devloped) MGB.
