For crying out loud change the tune and read what the posts actually say.
There is a standby machine at Stornoway, Sumburgh and Lee. (Shared with Portland.) All this you well know from previous posts. The standby machines are not LN450 fitted. Training is carried out on the main machine, LN450 fitted, or if that is off line off line for maintenance, then training is carried out on the standby, none LN450, machine.
The only thing that will change when/if CHC take over is that all aircraft, S92 and AW139, (where are they?)will be to the same standard. At least that is what the MCA have been told.
