In the AAC we used to cruise at 135 kts and there was an 'intermediate pitch stop'
Trouble with the IPS Rosev, was that it was a fixed power (ok - pitch) setting so the actual IAS achieved varied with AUM (and other stuff, like how good the donk was).
135-ish was a good average, but (readies hat, coat and flak vest) I suppose "ish" was OK for the AAC!
