Ok i am currently enroute(for a while now) with the 744 from CYUL to EHAM i'm still cruizing at FL330 my ZFW 274.9 (i know to heavy but i like it :))I am looking at my fuel flow on the lower eicas screen and it indicates that it's using 3100kg per hour per engine so right now i'm using 12400kg per hourMy research about the MD-11 cames out that each engine uses between 2200 till 2500 kilograms per hour with a 45000kg payload(roughly a fully loaded pax)The MD-11 has a maximum range of 6840NM with a total fuel of 146115 kilograms the 747-400 can reach 7240nm with full tanks means 173600kg so yes the 747-400 can fly further then the MD-11 does but can also hold more fuel and pax if the MD-11 would have had the same fuel capacity as the 747-400 then the MD-11 could fly further based on how much fuel each engine usesThat's my result correct me if i made a mistake

Hi Guys,Since I was the other person to dream up this challenge for you I thought I'd better kick it off with what I've got. This hole thing is just a challenge to see whom of all of you PMDG users that are the most fuel effecient. First flight done: EGLL to LSZH using the MD11ZFW: 164,8tonFuel: 17500kgsFlight time: 1H13MFuel used: 9720kgsNOW - Bring me those numbers so we can handle someone that Trophy

Hi,First flight completed here. Heathrow to Zurich.Flight time 1 hr 05 mins.ZFW: 377,796 lbs (~171.72 tons)FOB: 38,500 lbs (~17.5 tons)TOGW: 414,796 lbs (~188.5 tons)Fuel Used: 21,670 lbs (~9,850 kg)Martin's Fuel Index: 0.0589Robin's Fuel Index: 0.0573The fuel index is fuel burned divided by aircraft ZFW. Lower is better.Calculated against TOGW:Martin's Fuel Index: 0.0533Robin's Fuel Index: 0.0523Best regards,Robin.

No-one? :( Best regards,Robin.

I'm flying currently from amsterdam to denver but i am going to participate

I'll try the London-Zürich route.

I flew the short route in the 747.90,000 lbs of payload62,600 lbs of fuel loaded.19,000 minimum landing fuel.7,200 lbs of alternate fuel.30 min reserve.26,000 lbs usedRoute was 477 nm.Flight lasted 1.1 hoursAverage GS: 433Fuel Consumption per hour: 23,63054 lbs/nmRobin and Martin: What aircraft were you in? The MD11?ADD: Answer to your post below. ZFW=484000, my fuel index is 0.1293

Hi,Yes - MD-11.yos233: Based on the above figure you have a fuel index of 0.0476** EDITED **Best regards,Robin.

Ohh, yeah. Fuel Burned, not what was loaded.

Ohh, yeah. Fuel Burned, not what was loaded.

ZFW, FOB, payload, fuel burned, and flight distance are great.I just looked - 747-400 OEW (FS9) is 387,288 lbs.EDIT: I edited my post further up to reflect your ZFW.Best regards,Robin.

Hey guys,Thanks to those of you who took up the challenge and interesting results so far. Keep it up Here are mine for the CPH to DXB run.MD11TOW: 253,7tonFuel 61000Flight time: 5H38MFuel used: 46780kgs

Those of you who visit the 747 portion of PMDG know that I am obsessed (its a healthy addiction) with Google Docs. So it is time for me to infect the general forum.This link takes you to an editable spreadsheet where you can edit your data which we can compare. I think I got everything that has been posted, but check over your data. (Everything is in Imperial units)

Hi Eric,That's an awesom tool. this will make comparison flights very easy. Now all people gotta do is fly them flights I apprechiate it

Interesting test. Of course the fuel burned is not the only indicator of the economy of the flight overall, since maintenance costs come into play too. For example, you can use a higher thrust setting on the engines when in the climb, making them run hotter, but that could still put less stress on the engines because they'll be at that climb thrust setting for less time by getting up to the cruise altitude quicker, where you can then throttle back sooner.It's nice that we can if we wish not worry about such wear and tear, but since the PMDG 737 NG for FSX will allow us to monitor such parameters, that's when we'll really be able to check the overall economy of things.Al

Hi Eric,Great! I added a new column (GW) and corrected the Fuel Index calculations.Best regards,Robin.
