Oh, those altitudes...

[TAROM 9]

Hello.

I was curious if the developers intend to release a update with an option allowing a simple way to get rid of those annoying altitude restrictions in the flight plans...

I'm really not happy withe the answers I've seen in the forums about the issue.

I know the developers tried to get a product as real as it gets, but they also need to consider  that many of us use  this program just as a tool in order to have an OFP for the really interesting part: the flight simulator and not because we are passionate about about being a dispatcher.

And what are the available flightlevels for the direction of flight on the airways in use in the AIRAC that your using? which is why the levels change.

PFPX meets those requirements generally very well, after all you are you the most advanced planner available to the community.

If you don't care about the altitude simply overwrite your cruise level and tell PFPX where you want to cruise.

Just change the INIT Cruise Alt/FL from OPT to a fixed number, say 360, then it'll plan the complete cruise at 360.

This kind of thing happens to me. Sometimes, in a 12 hour flight, the first altitude (generally FL310 or 330) will be... FL190. And also the "descend" in the middle of the flight, let's say... from FL360 to FL340 and then climb to FL380.

Starting a flight from São Paulo (Brazil) to Paris, for example, we use 4 flight levels (in real, i work in a company that flies B77W). The flight levels are 310, 330, 350 and, entering in Europe airspace, we climb to 360 and we stay in this Fl until the end of the flight.

It is not possible to fly at FL360 all the way down to Paris, in a 10h46 flight.

It's not a bug! PFPX always looks for the best winds vs Performance vs Cost Index. In case you don't like it, you can always override the automation of PFPX  in the advanced tab.. It's called "Speed/Alt restriction" I believe (I'm currently not on my computer)

Thanks for the answers.

Stephen, indeed they come from the AIRAC. But I have seen real OFPs from airlines form European flights and on none these intermediate descents and climbs don't appear. And the planes do not do that in reality.

Emmanuel, I've tried, it doesn't work.

Renato, I only do intra-european flights

Patrick, I will explore the Advanced Route Finder.

 

 

[srcooke 422]

I agree you are more likely to climb incrementally as suggested by Renato. Again as Patrick has pointed out PFPX will always use the optimum altitude, just peg the segments in the 'advanced tab', not the Advanced Route Finder.

Thanks, I'll check.
