Thanks, chaps. If you look at 'Rotorheads' topic Autorotation you'll see I've chipped into that debate. I was at work at the time...paradoxically without my tps notes, with which I have now refreshed my memory.
I don't have BCAR here, but my extracts from 00-970, which refer specifically to (rotorcraft)FCS failures strike the odd chord. Furthermore, the 2 seconds for engine failures is cited as the 00-970 requirement 'as a realistic reaction time for the average pilot to identify a total power loss under unfavourable conditions and then to lower the lever'; 'active'response time is 1 sec but 'attentive hands on' pilot response time is given at 1.5 secs.
The JAR requirement for engine failures is given as 1 sec 'or normal pilot response time, whichever is the greater'. Mmm, very useful if normal PRT is not defined!
Since JAR are very close now to FAR, I suppose the FAR standard may be followed.
Incidentally , on the subject of 'lever delays'in the R22 even a planned 1 sec delay in the climb at 60 KIAS was, to say the least, exciting.....
Any more comments, please?
