To the best of my knowledge the BO-105 never had a published Cat 'A' performance. In fact, way back when the type was introduced in to the UK wasn't the single engine performance so bad that the UKCAA required a fuel dump system to ensure an adequate single engine performance, these modified helicopters were designated BO-105D.
A few years ago I was involved with a BO-105LS operation that ultimately failed because the operator couldn't satisify the clients Cat 'A' performance requirement. Yes, the BO-105LS has bags of power, but we wanted a manufacturers published Cat 'A' performance supplement that simply wasn't available.
I'm therefore surprised, Daddylynk, to learn you have a "supplemement section which talks about CAT A and VTOL" could you give further details.
