October 17, 20223 yr I was having an issue with the Fenix A320 and could not find a solution elsewhere. Essentially, my Fenix A320 sometimes slows down to green dot speed while near the top of descent. Gear up, flaps retracted, no ecam messages and everything should be configured properly. I've done dozens of complete flights with this plane and only recently have I encountered this. It causes the plane to slow way down to under 220kts, which turns off my nav mode and flight directors. It then goes into heading mode, and vertical speed. MCDU said something like "no nav intercept" which I cleared by going direct to my next waypoint. Manually setting the speed does nothing. Then, seemly on it's own, the auto throttle begins to work and goes to the magenta arrow and not green dot once at cruising altitude for a few minutes. Here is a before and after:before and after

Here is a before and after:before and after It will decelerate to green dot at TOD if you don‘t descent, so you lose some kinetic energy and have an easier time getting back onto the descent path. So it‘s working as designed. You should, well, just descent at TOD. Why wouldn‘t you? If you want to descent later, just move the TOD by choosing a higher descent speed in the desc phase in the FMC. Or go selected speed if you don‘t want to follow the path anyway. Edited October 18, 20223 yr by Fiorentoni For transparency: I'm a community mentor at the BATC discord. However, I do not get paid for it in any way.
