Hi hmb77;
There are Bristow, who still has a B206 Jetranger special IFR equipped. Their course is fully done on the Jetranger ..
Also the school I attend in Denmark at the moment, Billund AirCenter, has just recieved a B206 Longranger IFR equipped and approved for JAA-SE-IR(H) training. Their course is a combination of R22, SIM and Longranger ..
These two schools prices are fairly similary, Bristow a bit more expensive on the ab-initio course, but UK-CAA acknowledge ICAO IR(H)'s for a reduction in hours ..
The Danish CAA doesn't, each case has to be evaluated, so no guarantee with them ..
The B206 should be the only single engine approved for IFR training in JAA - so no R22/44 or EC120 or other helicopters can be used for the checkride ..
Talking commercial, you can only use a single-engine JAA-IR for upgradring / training ..
There are also CHC, but we are talking IFR training on a Super Puma SIM - better get the big VISA-card with you in that one ..
