Best flight/fuel planner?

Recommended Posts

hi guys!I use all pmdg products all of which are amazing! i also use active sky which ive got tweaked and is working well! no s turns and winds spot on etc etc etc!What fuel or flight planners do you use? for pmdg 747/737ngx/md11 and level d 767? Thanks guys!Andrew

I use TOPCAT, it's really great.
Doesn't TOPCAT usually give an over-the top fuel estimate?

The MD-11 has a built in fuel planner. There are some instructions somewhere on AVSIM by Dr. Vaos if I remember correctly. Here is the link: http://forum.avsim.net/topic/124419-md-11-calculating-fuel/page__hl__guess++fuel . See Reply #4 for his instructions. The 747 has detailed instructions in the manual. Chapter 2.

For fuelplanning I use this freeware programm, which is really precise! For takeoff planning I use TOPCAT, but I don't like the fuel amount estimated. It is without reserves...

There is also a fuel estimating option, but it is not as accurate as the freeware I posted above.

I use the fuelplanner I got from the PMDG website (downloads -> misc).

FSbuild is best for accurate fuel planning, TOPCAT admittedly from a few sources is known to not be as accurate as it dose not take into effect winds allot and is also can calculate taxi, alternatives, hold time etc. Most my 747/MD11 and now 737-800 flights planned with FSbuild have been within a few 100lb at the planned fuel along on route. I just use TOPCAT for loading of the aircraft and takeoff planned in regards to CG% MTOW etc

For the 747 I use my own custom made planner, check my signature for the link. The 747 manuals, ahh, what simpler times...happy.png I hope to be able to do the same for the 737 once I gather the many many (repeat that as many times as needed) pages of data provided.

Regarding MD11 and NGX, if you will fill all data required, winds aloft, destination forecast etc, you will get very precise fuel estimation. I can't say that for other aircraft you mentioned because I don't own them.

Here's a great one for PMDG's 747 http://www.supercell.nl/747FP/ Here's one that is fairly accurate and can be used for various types of A/C http://fuel.aerotexas.com/ I used this one for the Wilco PIC 737. Works really well and integrates perfectly with FSX. Haven't tried it with the NGX yet though. http://www.volny.cz/...FPL/B737FPL.htm Here's an old Fuel Planer for a 767 http://www.avsimrus....ion=download= And http://nofuel.thatssailing.com/flightsimulator/fuelplannerb763/default.asp

I use the FMC.
That is what I have been doing as well, and to tremendous results. The FMC on the NGX is no joke, it really is darn accurate, especially when you enter the winds in and the ISA deviation.

ISA deviation.
Can you elaborate on this please? Where do you insert this in the FMC and how do you calculate it? Thanks!

It is in the init page when doing pre-flight. Same page where you enter the ZFW, the fuel, the Crz Alt. One the left side you can either enter a TOC temperature and let the FMS calculate the ISA deviation, or enter the ISA yourself. You can also enter an ISA deviation, as well as arrival QNH, and up to three winds aloft in the descent forecast page to help calculate a better TOD and descent path.

Will have to take a better look at this... Thanks Scott!

I think "pen and paper" is usually the most accurate (freeware) way to calculate your fuel. :)

On Init 1 page.To calculate your ISA deviation, here's a good rule of thumb, which will also help you with your Take off performance when setting up your Flex Temperatures for your engines..It's simple (I'm using celsius here, but I think that's the unit the FMC uses anyways):- Consider a 2ºC temperature decrease for each 1000' feet above Sea Level for your departing airfield.- Exemple: Guarulhos (SBGR): Field Elevation 2500' ASL, so for every 1000' we consider a 2ºC temp loss, so ISA Temp for SBGR is 10ºC.- Then you check your actual OAT, that's visible at the upper DU, or at your Metar report.. Let's use 25ºC for this case.. So, ISA OAT is supposed to be 10º, but actual OAT is 25ºC, so you're 15ºC above ISA..And there's your ISA Dev. right there.. Cheers

Um just trial and error with the FMC PROG page?
I'd take that would be on the ground. Would hate to have a pilot learning on the job... But that's just me.
