I decided that I would give a P3D aircraft from CaptainSim a shot, and I am feeling massively let down again. The VNAV is nonsensical, it ignores altitude restrictions and constantly commands a -6000fpm descent. The approach mode on the autopilot is also broken, it doesn't show a glideslope or localizer on the display yet it says they're captured. After the aircraft said it had captured the glideslope, it still continued to command -1800fpm down, and I crashed into the ground ahead of the runway.

Definitely wishing I could ask for a refund, I have been burned by CaptainSim twice now on completely non-functional products and I will never be buying from them again.
