Hello everyone,
I was flying from KLAX to VHHH and had loaded in a route before T/O. Everything was working fine until I saw that the route I had loaded was not the most efficient due to strong Pacific Winds. I went back to simbrief and reset a new route unchecking plan stepclimbs. When I went into the route page and requested a new route, everything loaded fine except for the VNAV data. The route was there and I could change the altitude in the VNAV cruise page, but none of the data was on the route. The Perf init page was still in order, but I couldn't arm VNAV. It kept saying VNAV perf unavailable. I searched this around a bit, but could not find a solution.
Thanks in advance!
