Auto pilot calculation incorrect


f-ger_cmd

Recommended Posts

I loaded a flightplan from 2016 from EDDF to LDDP

Distance is 1653 miles and the sim indicated 1:33 flying time which makes no sense

I checked in the MCDU and found a strange calculation between QPD and (T/D) with 1020 Miles to go in 17 minutes ...?

 

Can you check if this is the load or just wrong?

Thanks, cmd

Time time looks correct for a flight from Frankfurt to Croatia, but the distance is certainly not.

Could you give us your full flightplan and payload details so that we can try to replicate this one?

EDDF to LPPD is Acores ... (I mis-spelled above LDDP, apologies)

Load:

PAX 156

Cargo 6.0

Fuel 12.0

 

Init page: EDDF/LPPD, CI 50, CRZ 340

F-PLN: EDDF 25C, WIB, ELU, TOC, REM, LHO, QPR, TOD, LPPD

 

see picture above, 1658 Miles, Time calculated 134

Between QPR and (T/D) is 1016 Miles but time calculated is 114 to 132 ???

 

Miles differ a bit as still on ground versus picture which was shortly after take off

I entered this time plan manually, so it is not a load issue

 

Thanks for checking ..

After entering now an arrival runway, time goes to 348 for 1664 Miles ...

 

But it should calculate flight time even without runway information ... or?

Hi Mathijs,

 

just checked, I think it is a wider issue not fixed with 1.1.0.0 release

INIT page added eddf/lppd, CI 40, FL 360

see left active sky flight planner

right F-PLN, even with discontinuity, distance and time wrong with no way points inserted:

now I remove discontinuity and distance corrects itself but time incorrect:

now I added the arrival runway 30 in lppd and time changes to correct duration:

I hope that helps, I would expect estimated time and distance to be correct even if you have a flightplan discontinuity, or is that not correct?

 

Thanks

Just to add on my story

Flight KBOS to EGLL

all fuel and weight inputs done

even added a runway at egll (27L)

In flightplan page, it predicts landindg on EGLL27L at 0018 UTC

But one row below, it says DEST EGLL27L with 1459? Am I missreading this?

I know you are working on this but wanted to share more facts ..

Thanks

Christoph

Let me know if you need any more information

 

By the way, when I recorded this, it was UTC 21:15 roughly ..

so landing prediction of 00:18 is about right, maybe only a display issue for DEST UTC display?

 

I really like to help and not complain :) 

Thanks

Have a good weekend

now on final, DEST time was corrected, see picture

but referring to other posts

flightplan indicated for a descend from FL340 to 3000 ft only 89m causing these steep descen rates of more than 4000fpm

in real life, a flight would descend at 120 nm or?

I only managed to get to EGLL with speed brakes out right after TOD .. why?
