@ TeeS:

I do have a flight manual for a B2.

Max transient tq = 107%
Max takeoff continuous tq = 100%
Max cruise continuous tq = 94%
Max transient Ng = 107.5%
Max takeoff rating Ng (no bleeds) = MTP = 101.9%
Max continuous Ng = 98%

Anyways; these values give me places to put the red marks on the gauges, but no way to make the gauges respond correctly to atmospheric changes. It is starting to look like the only way to correctly calibrate a simulated VEMD is to take a test flight. Using the power check chart would be nice, if it was easily discernable: see http://www.pprune.org/rotorheads/540...eck-chart.html for that discussion.

Not too worried about T4/TOT, because French engines are designed to not be temp limited is what I've been told.

An interesting side note about the flight manual: it says that MTP = 101.9% = 0 delta Ng. It also says that MCP = 98% = -3.5 delta Ng, but 3.5 + 98 = 101.5???
