PFPX planning early descent when step climb enabled

Recommended Posts

An early descent and level-off is planned shortly before the actual TOD.

Any idea on why this would happen? No restrictions are shown in the route. Disabling step climb (setting it to "no") prevents this from happening.

Not sure if this is a remnant of pre-release early decent function or an error with the step climb function which exhibits other issues.

Not sure if this helps, but this bug appears to only occur when the flight doesn't require a step climb. It looks like when a step climb isn't required, PFPX sets an excessively low initial altitude and an early descent.

I've noticed this too.  Get FL240 in the for the FSL Airbus YMHB-YMML, where optimum is FL340-360 depending on weight.  I have to manually change altitude to find the most fuel-efficient.

 

This altitude stuff in PFPX does need to be rectified.

It seems that a work-around is to set step climb to no for short flights, and only turn it on for longer flights.
