B747-400ER/ERF

Recommended Posts

Does PMDG have an upgrade to bring the -400/400F up to -400ER/ERF specifications? I would like to fly some of the long flights and the -400 comes up a couple hours short on fuel. I considered going into to *.cfg file and making the necessary adjustments, but I was afraid that might adversely affect the balance.Bill

There is a very good probability that altering the cfg will severely mess things up. The sim does not use the msfs datum for moments, it is modified to use the actual datum (arm length from the front of the plane instead of from the static cg).They don't have the ER modelled.

Dan,Thanks for the reply. Maybe the ER/ERF is the new mystery plane. :( Bill

Hmmm. A 747-400 can't fly far enough for ya? Talk about a tough customer. When's your birthday? I'll get you a 777-200LR or an A340-500.Paul

Loose a few passengers and throw their bags out too. Keep strictly to your step climbs and you too can easily fly LAX to Melbourne direct as QF93, or Sydney to San Fransisco, or Brunos Aires to Sydney. or whatever ER route you're wanting to fly :( Activesky only, as close to the real flight time as possible, with a real flighplan (Flightaware as much as possible, this is to get proper winds). Done it in the standard -400 plenty of times. (Theyre the routes QF use their -400ER's on mostly)Hong Kong to New York's also a fun one over the North Pole (or very very close to it at least)If you don't hit FL400/FL410 by the end, you're carrying too much stuff. Chuck some people off :(

I can easily do that with the 747 and the md-11 can do it nicely too even at 400.000lb zfw

Pretty amazing how far aviation has come. My first airplane ride was on a Super Connie KSFO to ROAH w/ two refueling stops, Pearl and Wake. Those were the days....... :( VincentP.S. as Jimmy Stewart once said "you use to take pride in ...Just getting there"

You can always add 6480 us gallons of fuel when it's low enough simulating the 2 x 3240 gallon tanks. Can't add to the weight though lolJohn E

I flew from LAX to Melbourne once, filled the old girl to the brink and then put as much passengers and cargo to MTOW. I got there, but less than 10,000lbs of fuel left at the end. Started chewing the fingernails halfway between Fiji and the east coast! Not as much as the virtual pax in the back, I guess.Cheers, Chris D

I was wondering the same thing about a modelled 747 400ER/ERF, and found nothing across the web..For your information, i did modify the .cfg file, and everything went well so far... I just modified the fuel center tanks capacity, by incrising it to a value that i don't remember, but you can find it on the Boeing website..Cheers,Daveoops "increasing it"... :-)

UA does LAX/SFO to SYD, IIRC that is a 400 not a ER. Even the ERs have to stop at SYD or NAN every blue moon for Jet A.

It doesn't seem to take PMDG a lot of work to create a 400ER model, why not do it?Sam

Found this thread in a search because I was wondering about the -400ER It looks to me that the -400ER is essentially the same as the -400 but with extra tanks (which increases the ZFW over the -400), so I can see that editing the .cfg to add additional fuel tanks would be disastrous. My question is, would there be any problem simply editing the .cfg file to add the fuel capacity to the existing center tanks? Dan Downs said it would screw everything up, but someone else said they've had no problems. Can someone from PMDG weigh in on this?Fidel Lopez

Well, it was more of a hunch based on incomplete information. Geeze.

Do not mess with the cfg, there's a ton of custom coding going on (especially with the fuel system) and if the panel doesn't see the right values in the cfg it's going to freak out and do weird things.

Personally i think you can do for example SYD-LAX with a 400 done that flight a couple of times just don't take full ZF fil it up with 1/3 of pax and full tanks you will mke it just fine

I've done LAX-SYD no problem. My neighbor's wife is from down under and they travel there every year with two small kids. At least I can sim it in my office chair, at a lot less cost. 'Course, I don't get to see the fauna and flora.

What I tend to do on my MD11 (since my 747 is currently in the post) is fill the pax cabin and empty the rear cargo hold leaving the five pallets in the forward. Then fill the fuel all the way up and ajust the cargo so your Zfw etc isn't red. Bang your done. I flew for 11 hours non stop with 7% left over try this and see the results you getDylan Leonard

Dan, I didn't mean anything negative! :( But I guess I should have been more careful with my wording because you had said "severely mess things up" not "screw everything up" as I said. :( Anyway, according to Ryan sounds like you were right. Based on what I've seen in the PMDG forum, your "hunches" are usually correct.Fidel Lopez

There are actually quite a few more differences between the 744 and the 744ER/ERF.Of course there is the two AUX tanks which everybody knows about. This means the ER has two AUX fuel pump switches on the fuel control panel. So a simple .cfg change will not give u a ER especially since the AUX tanks mean the fuel system has a different software loaded on the ER as it has different trigger points.(Boeing even had a team at LAX waiting for every ER arrival for a month to load up a new fuel system software as they were having some issues at first) Furthermore the tires are 1" larger (not that that you would notice that in FS :() Qantas ER's are also the only 6 744s with the new WXR-2100 Multiscan WX radar.Leo Calzoni

Leo, the addional switches and software are not surprising to me. Makes sense that you'd need more switches for more fuel tanks. It's very interesting, however, that the tires are 1" larger. Does that allow for more psi in the tires to account for the higher gross weight of the ER?Fidel Lopez

I do wish PMDG added weather radar, updated vc textures and modeling, and an ER/ERF variant. I would buy an expansion package for 30+ usd

Two Aux tanks are most definitely an option, but I haven't heard of anyone taking up that option. Qantas only has one Aux tank. The overhead panel Aux Fuel Tank switches arm the automatic fuel pumping process, but the Aux pumps may not necessarily be used to empty the tank. This can be done by differential air pressure. If the diff pressure is low, air pumps pressurise the aux tank to transfer fuel from the Aux Tank.
Qantas ER's are also the only 6 744s with the new WXR-2100 Multiscan WX radar.
I'm pretty sure I've seen Multiscan Radar panels on other non-ER airlines (e.g. Air New Zealand... and this was, perhaps, even prior to the introduction of the ER). Neither is the ISFD (LCD type standby instrument) exclusive to the ER's.The ER's also have a different cargo fire suppression system, different ignition system logic and hundreds of other minor logic/detail changes.Rgds.Q>
