Hi,
I read the latest longitude FDE mod change log and they state in relation to the longitude:
"Important note 2: Asobo have implemented a mach meter and mach hold setting indicator in the PFD speed tape. They have also fixed the Mach Hold functionality to work properly as altitude changes. These are welcome fixes / improvements. However, the barber pole in the speed tape is now further bugged and is now tied to the Mach meter transition speed (transition between True Airspeed indication and Mach). This is set to Mach 0.78 in the mod (0.79 in Asobo’s latest update). This means that once transitioned to Mach readout above approximately Mach 0.78, your airspeed will be in the red. There is no clear fix for this other than doing away with the mach meter except when above Mmo overspeed (Mach 0.84). I’ve elected to leave this alone for now so we have a functional Mach meter and hope that Asobo will correct in a future update. "
Perhaps this issue/bug is also on the TBM as well?
Also I notice you have 29.92 and 29.97 on the backup.
