We keep hearing that 6000 of these units have been used without incident but how many of the Mark 2 version are in service?
A really good question! I would hope that the 6000 figure Honeywell claimed when this started relates to 6000 of the same model as is fitted to the 787, it would be very far from honest of Honeywell to have claimed that if, for example there are 5900 Mk1 and 100 MkII in use and those are all shipped to 787s!
