Changing flight plan

Does anyone know if you can change a flight plan whilst in mid air. Specifically after you are given a runway to land. Thanks in advance.

At this point I think it depends on the aircraft and whether you are using any mods. In the Mooney with the GNS530 mod, yes you can.

There are active mods for the GNS530, G1000, G3000, and the A320. They are all works in progress that are gradually aligning the sim with RL functionality where able. There are limitations based on what Asobo has exposed in the SDK. The devs seem to be coordinating fairly well to prevent adverse interactions between mods.

Thanks guys, but as I fly only the DR400 which has steam gauges I was thinking maybe importing a new flight plan via LNM and somehow refreshing the current flight plan in MSFS.
