Hello to all:
I am new to X-Plane and very new to the B737-300.
I have a puzzling problem that I am unable to diagnose. I have searched the forum and I apologize if I missed an existing response.
The issue is the IAS. After take off, with the aircraft fully cleaned (and confirmed externally) the speed tape shows red, above 227 kts, regardless of the altitude.
VNAV will not exceed that speed. any stting of A/P will not exceed it either and sometimes, I manage to manually increase the speed.
Invariably, the IAS window will revert to 227 KTS with the flashing symbol in front and the aircraft will slow down if going any faster. As a matter of fact, the flashing symbol does not stop, regardless of the speed I select.
My system is:
Windows 7 Pro 64 bit (with all required updates)
GeForce GTX780 graphic card
I have a number of GoFlight modules. Only the MCP and TQ6-ADV Throttle Quadrant, are mapped to X-Plane.
One throttle lever is mapped to all throttles.
I have a few other add-ons (PMDG DC-6 and FlightFactor B757, that are operating OK.
Any help and guidance are greatly appreciated.
Regards to all
Roberto
