I will test it as soon I will have the next Package.

Last post by pierre - Sep 06, 2023, 11:14 AMHere is the last message from Navigraph :
Hi Pierre,
just an short update - we are ready so far with the CPS-NG adapter and it´s now in our QM state system. We have only one thing which is missing at the moment and which need more attention: it´s the runway slope ... this value isn´t in the source data and we calculate it in the old parser but we don´t calculate it in the new parser. So, we must implement this feature and therefore we need a few more days. I´m on a training from today on till saturday, so not so much time but this part is hand-over to a college of mine to implement the slope-feature in the new parser too.
Hope that´s ok ... but all other things are ready and when the slope is included, we can move the adapter to production ...
Cheers & thank you very much,
Richard

Last post by pierre - Sep 04, 2023, 04:16 PMIt is actually impossible to test CFM, as X-Plane real weather doesn't work.
Waiting for fix....

Last post by pierre - Sep 04, 2023, 08:03 AMI don't know how are made the X-Plane flight models.
Increasing weight has no sens because this reduce again the ceiling. Same result decreasing engines power
An aircraft has always a max ceiling depending of weight, thrust and of air density, itself depending of pressure and of temperature.

Last post by gastonreif - Sep 03, 2023, 07:13 PMThat means we need to redesign the flightmodel or increase weight or decrease the engine power.

Last post by pierre - Sep 03, 2023, 06:25 PMMay be a little bit.
With Philippe Gleize, in 2010, we made hundreds test flights to adjust the virtual FE behavior and the fuel burn using CFM.
Finally, the curve (red) was very near the black one during the main part of flight. Through the descent and destination subsonic step the red curve passed below the black one then rejoined it at landing with a less than 2000kg difference.
I think the main improvement for Concorde Colimata and Heritage should be that the bird can't reach FL 500 before having a weight of 155t. (ISA 0) and FL 600 only with a weight of 98.6t. (ISA 0) or less.

Last post by gastonreif - Sep 03, 2023, 06:02 PMDoes this mean i should change fuel consumption? how much up?
