FCU Speed Lvars no longer available #57

Closed scotflieger closed 2 years ago

scotflieger commented 2 years ago

The FCU speed Lvars used to define the VRi FCU SPD display are no longer available in the latest development release.

These are defined in the Flight Deck API include:

A32NX_AUTOPILOT_SPEED_SELECTED
A32NX_FCU_SPD_MANAGED_DASHES
A32NX_FCU_SPD_MANAGED_DOT

Function A32NX_DspSPD is affected and will only display dashes.

The problem appears to be related to when an alternative livery (eg. British Airways OperatorLand468-a320NeoBA_FBW) is loaded.

The problem is related to how FSUIPC7 (7.2.15) loads Lvars. MSFS takes a finite time to scan and make Lvars available. It is essential to add LvarScanDelay=45 to the FSUIPC_WASM.ini file to cause FSUIPC7 to wait before scanning for Lvars.
