migueis 0 Posted November 19, 2015 Share Posted November 19, 2015 I use P3D And REX Essentials+Overdrive as weather engine. Sometimes (everytime) the metar on REX says e.g. QNH 1029 and even if i press the B key it shows in the plane for e.g 1021. The values are completly diferents. This occurs everitimes in the destination airport. Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted November 21, 2015 Deputy Sheriffs Share Posted November 21, 2015 Then do not press B, we do not have this possibility in the real plane, and just enter/select the correct QNH yourself. Do make sure that when you are on the ground, and you enter the REX QNH, that your altimeter also shows the correct airport elevation. If this is not the case then your main problem will be with REX instead of the Bus. Link to comment Share on other sites More sharing options...
migueis 0 Posted November 21, 2015 Author Share Posted November 21, 2015 But if i check the REX QNH it was equal to the IVAO QNH but the copilot in the checklist set another diferent QNH of both:s Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted November 21, 2015 Deputy Sheriffs Share Posted November 21, 2015 In this case I will move this topic to the Right MCDU sub forum. The people there have more knowledge of the co pilot functions than me. Link to comment Share on other sites More sharing options...
Deputy Sheriffs Hanse 216 Posted November 22, 2015 Deputy Sheriffs Share Posted November 22, 2015 Hi, I do not have REX but ASN and no problem with this issue. Are you inserting the DEST AP QNH (like in your example 1029) on the MCDU PERF APP page? If the problem then still occurs did you try it without REX e. g. setting in QNH value in P3D?

migueis 0 Posted November 23, 2015 Author Share Posted November 23, 2015 I think is REX issue because if i close REX and load it again the QNH is correct. Link to comment Share on other sites More sharing options...
