[Instruments freeze and aircraft freezes]

Same worry here, Load on cold dark, import from simbref a VQPR to VQPR by BOGOP BOGO1A. Import simbref to the mcdu and change the arrival for RNAV-Z.

 

Same worry also with cold/dark, set VQPR/VQPR and select RNAX15-Z. When the rnav is selected the MFS freeze completely.

 

I used the last AIRAC 2103 rev01

[Instruments freeze and aircraft freezes]

Same here, bug when i set approach during flight or on the ground during the flight preparation. Only way to continue the flight is reset completely the aircraft with dev aircraft selector.
Any have found a solution ?
