Last week, a user of my default FSX B737 Flaps Indicator in Italy asked if the gauge could be modified to cope with the PMDG B737. Since there were similar requests, I finally made a purchase of the aircraft to check the possibility.
After some modifications, the Flaps Indicator and Wet compass of the B737 gauges are now compatible with the PMDG 737 via extra versions customized for
the aircraft. However, the back light effect recently implemented on the B737 gauges is still ONLY good for the FSX Default B737.
Regarding the backup Altimeter with Airspeed Indicator in the B737 series, it is verified to be compatible with the PMDG B737 as well, although the gauge doesn’t exist on the PMDG.
As always, existing users of the B737 Flaps Indicators and Wet Compass should have received the updates in their mailboxes by now.
