Maximum thrust

[fernandafenelon]

Hello everyone,

is there a variable that outputs the maximum thrust on a specified altitude and speed?

Pretty sure there isn't. However you can get the information from the engine file, e.g. take a look at:

jsbsim/engine/CFM56.xml

Lines 14 to 15 in db4d967

	<turbine_engine name="CFM56">
	<milthrust> 20000.0 </milthrust>

jsbsim/engine/CFM56.xml

Lines 42 to 57 in db4d967

	<function name="MilThrust">
