flipster,
to fit anticipators to Puma would require a re-engine. The Turmo 3C4 is not retro-fittable(?) with anticipators. This has not happened because the Puma has been "going out of service soon" for the last 20 years, so it has never been seen to be cost effective to spend the money on new engines.
However, if it is to stag on until 2022, then current airworthiness standards etc mean it is no longer acceptable to continue with no anticipators. This is the main driver behind the "upgrade". It is not an upgrade at all, it is a life extension programme, indeed anything that smacks of upgrade for upgrades sake will be, if not already has been, ruthlessly scrutinised out. It is, if you like, just a happy coincidence that the 1A1s are more powerful, have better fuel consumption etc etc.
Only that which is absolutely necessary to allow this 38 year old ac to soldier on for another 13 years will be included in the Puma 2.
If it ever goes ahead of course.
