A300-600RF: PROF mode, Autoflight target airspeed zero & no top of descent.

[Haseen]

Dear:

I was doing a short flight from VGJR to VGHS, ILS RW 32, 79 nm. Cruising at FL130. No top of descent. PROF mode engaged. During descend, FCU speed window is dashed, but in PFD speed target goes to 0 (zero). I have to quit PROF and use VS and manual speed select. Please help.

The dashed speed window is probably due to a bug where it dashes itself if the CPT side DH window is active.

Dear Nico,

Thanks for replying!

Yes, but the AT target speed goes  down to 0 (zero) which is dangerous! Please take this into account.

As a temporary workaround for the time being use the FO DH and all works fine 😉

By the way, I tried the same flight with IniBuilds A310-300. That was great, no such issues with PROF, speed target etc.!

The autoflight system of A310 and A300 are same. But why the autoflight of A300, a paid add-on, is causing issues?

As I said, it is currently a known issue and will be fixed with the next patch 🙂
