Flight Level Even-Odd numbers

Recommended Posts

So today Im flying as KLM Cargo from EHAM (Amsterdam) to KMIA (Miami) and I noticed from before and now that the flight level are incorrect in my plane... What do I mean by that?

 

From Amsterdam to Miami the flight level should be even numbers, but instead, my FMC is "autostep climb" to odd numbers. I set the FMC to FL300 and after when there was les weight due to the fuel compsumtion the plane auto-climb to FL310-FL330-FL350. 

 

Now.. I shoud be flying FL340-FL360... and so on. Why is that happening? Is there a setting on the FMC (I looked but found nothing) to fix this?

So I ended up flying only with LNAV, since VNAV will make the auto-step climb.

 

Thanks for any support and excuse my english for not being that good.

Possibly you left the Step Size on the PERF INIT page at ICAO. Change it to 2000 for FL320, FL340, FL360, etc.

It work as you said, but is rare that the FMC by having ICAO set will give you the opposite of what the real life is, in this case for example my 777 PMDG doesnt invert the steps, just the 747... But thank you!
