When I click "Aircraft" in the top of the toolbar a little menu appears, when I choose and click on "New Aircraft Performance" (to create a new performance for a new aircraft) no screen appears to fill in. What to do?

This is like MS Word. When you click "New Document" there you get an empty document and have to fill that out yourself.

Same for the "new flight plan" function in LNM.

Now about editing: You can click in the main menu "Aircraft" -> "Edit Aircraft Performance" (Alt+Shift+E) to edit a new one. Or, even better choose "Collect Aircraft performance", do a flight and let LNM calculate and collect all aircraft parameters. See here in the manual: Aircraft Performance

It's not the same like in MS Word. In MS Word after clicking "New Document", an empty document appears on your screen (to fill out). When I click "New Aircraft Performance" I don't get a new empty document (which is supposed to appear on my screen, I presume) at all.

So, still no empty aircraft performance document visible to fill in a new performance for a new aircraft (apart from your editing tip).

The empty document is on the tab "Aircraft". Well ... I could open the edit dialog after creating a new one to avoid confusion. Let's see.

I've made a new aircraft performance for the Cessna 172 and saved it. So next, above the Toolbar I click Aircraft /Open aircraft performance. A new screen appears in which I choose "Cessna 172.Inmperf", I click Open but nothing happens: no screen of the Cessna 172 Aircraft performance appears.

The values are displayed on the aircraft tab together with a fuel prediction/plan after loading. I'll change this to show and raise the aircraft ab after loading or creating a new perf file to make clear what was loaded or changed.

I've found out that when opening an aircraft performance file to get it visible, the file being visible is only possible when you have loaded a flightplan. That is why - I suppose -  I did not succeed so far to get the loaded performance file of an aircraft visible (see my earlier mails). Do you recognize this? I suggest you do the same as I did (without loading a flight plan) then you will not see the content of a loaded performance file.

Another issue: I've tried to run "Collect Performance for Flight" with a Cessna 172 from the very beginning to the very end (typical flight). However the performance information, when collecting, is stuck in the climb segment. No further information after the climb segment appears. When I'm cruising that segment does not show, neither the descent and landing segment. The only thing I see is that in the climb segment the foot per minute descent rate digit decreases and that is all. After touchdown and engine shutoff LNM does not switch to the default fuel report mode. What could be the reason that the performance collecting process stops in the climb segment?

It shows only the header (aircraft type, etc. - if entered) because all other information is based on the flight plan. Open the edit dialog if you still want to look at the values. All shown on this performance report depends on the flight plan.

Flight plan was missing and therefore no cruise altitude. This already changed some time ago here in my development version where you can collect performance without a plan. Also, performance collection will run permanently in the background and allows to merge values into a present plan in the next release.

There were quite a few changes in this performance stuff.

Okay, let's get this straight: flight plan was not missing, despite cruise altitude. I've made another flightplan in LNM, in my case (but is does not really matter) a VFR flight from EDDT (Tegel) to EDUF (Lonnewitz): 61 nm, DCT. A/C: a Cessna 172. I've activated Edit Aircraft Performance. After starting up and take-off, aircraft tab of flightplan window shows the climb segment (so far so good...).Then when the climb is finished and I continue at cruise altitude of 3000ft, no cruise performance info is collected or shown. So for clarity: I've loaded a flightplan in LNM and in the flightplanner of FSX, the flightplan is visible in the GPS of the A/C and is active, but as I've already said in my earlier mails: the performance information does only show the climb segment and that is all. It just does not work: why?

Does the flight plan that shows in LNM also list 3000 ft as the flight level?

Airernie, your question triggered the solution: when I opened the saved flightplan (EDDT-EDUF), the Flightplan Dock window shows under tab Plan 3.500 ft VFR. Till now I flew this trip at 3.000ft not realizing the 3.500ft showing in the flightplan (I did not set that altitude in the flightplan myself, it was just there believe it or not). Well just to make sure, I've made a new flightplan and now I set a choosen altitude of 2000ft in the Flightplan Dock Window tab Plan. Started the A/C, clicked Collect Performance for flight and took off. First the flightplan window shows the climb segment and when reaching 1.900 ft approaching the cruise altitude of 3000ft, the cruise segment appeared in the flight plan window (!) and then the descent segments (hurrah). 

The reason that the performance information stopped when I was in climb segment (in the 3.000ft-scenario) will be that when flying  I did not reach the 3.500ft altitude of the flightplan for cruise. I flew in fact only at 3.000 ft. So I think LNM is only triggered to go in the next segment (descent) when you first have flown your cruise altitude of 3500ft according to the flight plan.

Sometimes solutions are for the taking...thanks (and Alex) for your help.

STRANGE THINGS... in Littlenavmap fuel calculation in LITTLENAVMAP PROFILES

Hi mates.

I've made several flights with Airbus 319 by Toliss and I've collected the performance.

The final results: Everything seems to be fine. Littlenavmap calculates the fuel consume in a satisfactory way.

However I´ve made the flight from LEXJ to LEPA with FlighFactor A320 and Fslabs A320 and the results are very strange: The fuel consumed should be 3546 kg, but the results with Littlenavmap are surprisingly high.

(I have used a Cost Index of 45)

- Initial Block Fuel in depots: 5786 Kg

- Time from LEXJ to LEPA: 1:16 M
- Fuel remained in depots: 2240 KG
- And the results should be: 5786 Kg-2240 Kg= 3546 Kg burned fuel.

And Little Nav Map has collected profiles in which of them, the consumes are 8000 kg or 9000 Kg.

It's absolutely abnormal. The plane was loaded with 5786 Kg of Fuel.

Would do anybody cast me some light about this matter? I don't understand a word.

Thanks in advance.

HOWEVEEEEERRRRRR! If we take a look at Littlenavmap Logbook, everything

seems to be OK: Fuel consumed: 3.140 kg, 3.912 l

QUESTION: Why the results shown in Logbook seems to be fine and the calculated profile differs from the logic burned fuel? Average fuel flow: 2.692 kg/h, 3.353 l/h vs 7194 kg/h.

All of these matter seems doesn't make any sense???

I answer to myself.

Question solved!

I was doing the calcs badly. It's necessary firstly click on "new aircraft performance" and then " collect performance for flight"

I had the toliss A319 profile selected and when click on " collect performance for flight", the data the programm gave me was something odd, because I didn't select the option "new aircraft performance"

Hi ALex

For now when i click right on  airport : show procedures  SID STAR and TRANS.... no information on all airport in little NAv MAP .

What i can do for recovering  ??

 

Thanks

and all my friends have the same issu we are 14 guys .

Have you installed the AIRAC 1909? That problem happened with AIRAC 1909.

Something is wrong in the new AIRAC. Come back to the 1908 AIRAC and your problem will be solved.

Hi mates!

Another again with New Performance Profile.

Making the FlightFactor A320 Profile Performance!

Something that I think It doesn't work propertly.

LittleNavMap is indicating that the plane in Cruise Altitud is burning 7000 Kg of fuel/hour.

However the fuel burned is actually of 2000 Kg/hour

Does LittleNavMap work propertly?

Update Navdata to r2. This is already fixed. But a bit offtopic in this thread ....

Sorry, did not read all above. But it might be that the Airbus is limited by FSX/P3D FDE and "doctors" the fuel flow. I can only read the values from SimConnect. What the Airbus displays in the cockpit might be tuned and be different from what the Simulator reports to applications. There are a few complex aircraft which have to do this in FSX/P3D.

Sure it does. Always. :wink:

Try again with units set to lbs/gallons. There might be a conversion missing but this is unlikely.

Try to compare indications in other aircraft.

BTW: The whole performance stuff has change for the next version.

Thanks Alex.

Yes it must be that, because LittleNavMap works like a charm with the Toliss A319 CFM.

I´m looking forward to seeing the next version. More over I´m looking for a true Logbook.

Thank you for your quick answer and thank you for your time and effort.

I have tried several times with Fslabs A320 and FF A320(In Kg and Pounds ) and finally:  nothing.

Eventhough the logbook entries do show the correct data (the correct fuel burned in both planes), however the flow fuel is pretty low on collecting performance profiles and consecuently the profiles of these two planes are not correct. These two planes seems to be little friendly to show their truly data, Lol.

On the other hand, the performance profile of the Toliss Airbus A319  seems to be pretty, pretty exact.

The good thing is that the information contained in the logbook is absolutely exact: Zero fuel Weight, Initial Block Fuel, Fuel Burned, etc...

 

As far as a logbook for tracking and save every flight with every data, righ now I´m using ProjectFly, but this doesn't show the amount of data and fidelity of Littlenavmap.

I hope We can see soon a true logbook in the next incoming version of LittleNavMap or another future ones. 😉

@papelino The logbook simply uses the difference in fuel weight between takeoff and landing. This did not change.

The performance collection uses the average fuel flow from the simulator not looking at flight time. Therefore you can pause the sim, move the aircraft to TOD and it is still correct (if you stay a few minutes at cruise).

You can ignore the measured fuel burn and modify the numbers manually. Keep all measure numbers except fuel burn.

A very good idea! I'm going to do it right now.
