Support overload. We are currently seeing 65% more demand for support then we normally see. We can only assume this is because more people are at home due to the corona crises. Our complete support staff is online and they are working flat out, but it will take some days before we can scale up resources. Please be patient.

OPT FL Always FL240 ?

Recommended Posts

Hi

I have just created two routes, EGKK - EGNT (280 miles) and EGKK -EGPH (350 miles) using upper airways.

The aircraft is the PMDG 737-800, so performance is not a problem. OPT is selected in the Aircraft - Cruise Altitude/FL box and as I said before the route is constructed with upper airways from the official UK Standard IFR Routes. I have selected 'No' in the Step Climb box so assume I would climb straight up to the Optimum Flight Level.

After the flight is computed, in both cases I only get FL240 as the Optimum FL when checked in the OFP tab after I have computed the flight. This is well below the Optimum flight level for both routes.

What am I doing wrong ?

Look down in OFP!

Behind "INIT ALT" is only INITIAL ALT!

But when you look into the flightplan, you may be see the cruiselevel.

I added this in OFP-Template:

FINAL CRZ ALT: <&FinalCruiseAlt:10>

But this Shows NOT!! the MAX CRZ ALT or the CRZ LVL (for FMC)

Solution is only to look through the OFP and search the Flightlevels behind the Navaids!!

Flying the 737-800WL...I have used optimal for cruise and I have gotten from FL360 to FL390, so it seems to work fine for me.

Selecting no step climb forces PFPX to climb to the initial optimimum/allowed altitude (in your case 240) and then maintain this altitude until final descent.
