hi, for an upcoming university project I would like to
add autoflight/fms functionality to a flightgear aircraft.
Two essential features for this project would be a
working implementation of the VNAV SPD/PTH and LNAV modes.
However, in real life the flight management computer
uses a performance database that contains tables
describing the aircrafts performance in various
situations (configuration,weight,fuel,altitude,winds etc)
Without such data it is practically impossible to be
able to predict whether the aircraft can accomplish
certain waypoints/restrictions. Particularly the VNAV
PATH and SPEED modes are quite tricky without any such
data. So, I was wondering if there is any way to have
JsbSim sort of predict the performance it can provide
to the simulator.
