Fuel Planning bouton

[HawxNS]

Hello,
Why isn't the Fuel Planning button active? Do I need to do anything special?

Hello,

Have you imported a F-PLN? 

Thank you

Thank you for your reply,

Yes, I've done it!
I've noticed that you have to manually fill ZFW and EFWCG for the button to activate and fill the block. However, the quantity of block is wrong and does not correspond to what is in the aircraft.

Hello,

The "FUEL PLANNING" button becomes available after you also have imported the fuel and weight information via the OIS. That setup needs to be done prior to filling in the details. Can you grab me a screenshot of your weight & fuel screen on the OIS then the MCDU?

Thank you 🙂

There are 6 requirements for the button to become available: Engines are off, a flight plan is inserted, a cruise level is inserted, ZFW and ZFWCG are inserted, no block value is inserted. There might be a discrepancy between the calculated value and your actual value since there are 4 factors to calculating the block value. If you change any of these 6 factors after using the FUEL PLANNING button it'll cause it to be different.

Thank you,
What are the 6 factors taken into account?

I don't change them afterwards, it's at the time of setting up the aircraft before departure, whatever my flight plan, follow the steps in the init, enter the perfs... and once I've set ZFW & ZFWCG, the block is wrong. I then change it manually.
I'm going to test again and make some screens.

Ini probaby use the the wrong formula to calculate the block fuel with the button, the correct one is: BLOCK = TAXI + TRIP + RTE RSV + MIN FUEL AT DEST. Can you show these 4 values in your fuel and load page?

Here we go:

After import, I have modified the Fuel Load because by default, is to low !

Alright, so the following is the case: iniBuilds use completely incorrect ways to calculate MCDU values like block fuel, min fuel at dest, TOW, LW, etc. Assuming you didn't enter the "MIN FUEL AT DEST" value, the plane should've been unable to calculate it.

@Eddie Will we get this reworked please?

Exactly, the basic problem is that the performance comes from Simbrief (it's a shame it's not the LIDO EFB flight plan that's used, it's more accurate and reliable).
My process :
I generate the flight plan on the aircraft's OIS (which is only a replication of SimBrief and doesn't use the LIDO EFB at all), then, in the loading and fuel section, I import directly and there the fuel quantity is far too low, it only includes what is necessary for the flight, no extracts. I then modify it, and it's displayed correctly in the FOB.
I enter the ZFW & ZFWCG, then press the Fuel Planning button, all the fields fill in but are wrong, and above all, the block seems to correspond to the initial data from SimBrief and not to the FOB modified afterwards.

In short, it's not accurate.

Hello,

Thank you for the feedback. We'll take a look! 🙂 
(Have seen your other thread as well) 

Have a lovely weekend!
