Reproduction: this happens every time I attempt a landing challenge on Out Skerries or Southampton. Other landing challenges appear to be not affected.
@Habu2u2 do you see this same behavior? It would be very odd (and downright mean) if this was on purpose. In the Halloween challenge, it was obvious what was going on with the steam gauges because they weren’t blank, they were going haywire.
To have the PFD and MFD both go dark sounds like a bug. There have been similar bugs reported in other aircraft over various patch releases.
