Planned STEP CLIMB does not consider new vertical profile

Recommended Posts

I'm trying to plan a step climb with the A320 Pro 1.2.3. Doing so, the flight plan shows a S/C pseudo waypoint, but does not reflect the new vertical profile, as it should do according to the Thales FMS Pilot Guide. Is the STEP ALTS function not yet fully implemented? I have something like this in mind, but couldn't find it in the forum anymore.

 

Performing a step climb during the flight manually by just changing to the new cruise altitude in PROG page and on FCU works fine. Flight phase switches to CLIMB and returns to CRUISE, when the new flight level is reached. So, no issue here. It's a planning and fuel and time monitoring issue only.

 

See the following screenshots:

  • STEP ALTS defined and accepted (question: what does the message "OPT STEP: ENTER ALT ONLY" mean?)

  • resulting changed flight plan, showing the S/C pseudo waypoint, but an unchanged flight level and no T/C pseudo waypoint, where the new flight level will be reached

If you enter only an alt, the FMC should compute the optimal location for the S/C.

 

And yes, there are still a bunch of bugs.

All known. We are working on.
