I have just noticed recently that the range for some widebody aircraft have changed but don't seem realistic.

 

For example, the Boeing 777-200ER in game now has range between 9,200-10,900 miles when realistically it can only fly a full payload at 7700 miles. This applies for the Boeing 777-200, 777-300, and Airbus A340-600 as well which all seem to have non realistic ranges. 

 

What is going on?

A346 doesn't seem to be wrong, but all versions of 777 (-200LR and -300ER as well) now have some very weird range numbers, up from normal by some 15%.

wtf?

I do believe our favorite Oliy is currently in the process of sorting this.

I'm not sure, but from looking at the performance charts, I think the old numbers were in nautical miles (it's what they use in the performance charts), and they're being converted to statute miles to fix the numbers. I'm guessing Oliy can confirm or deny that.

I put in the numbers AE wants me to put in, AE gives you those range figures back after it calculates what it thinks the range should be. But yes, some stuff was in Nautical Miles instead of miles and I have corrected this along with other minor details I spot when I'm editing.

I also question these changes too. Mostly with the Boeings, Airbus is fine. No way does the 777-200ER have 9,000 miles of range, Boeing says the 777-200ER has 7,065 nautical miles of range, when converted that is 8,130 statute miles. In addition, I don't see much point to the 777-300ER now because the 777-300 has just about 200 miles less in range while having a significantly less amount of "fuel flow", with about 20,000 less "fuel flow" per engine. I understand that Oliy is putting the values that AE says to, but those values do not always correspond to reality unfortunately. .

This is ridiculous, something is obviously screwed up, seriously, this can't stay this way. 

 

It was fine before, only -300 non-ER needed a correction by some 1000 miles, but not like this 3000 miles longer, now it's almost the same as -ER. 

 

This needs to be re-worked ASAP.

 

AE won't make much sense if the most important airplanes start getting fantasy features.

Just go with the flow now. Imagine bob marley and fly high.  :)

Feel free to redesign AE.

I believe the 9000 mile 777 is the 200LR, not ER. Plus, you have to realize AE's realism isn't perfect. Yet....

The ranges AE use is the MAX FUEL range and not the MAX PAYLOAD range, therfore as AE use calculations to get up with max payload range there will be odd numbers.

 

this will however be fixed in AE4 when realistic Payload/Range capability have been added.

untill then there will be odd numbers at AE untill furter notice on how AE Data is beeing collected.

For every aircraft, there are two ranges listed in the game: the smaller one is the max payload range (the point after which you will see weight restrictions), and the bigger one is the max fuel range (at which point you will have 0 payload). Data collectors enter the max fuel range (in statute miles, not nautical miles), and the game makes a rough estimate of the max payload range. As such, the max payload range is not designed to be accurate to payload-range charts. In AE 4, we will use more comprehensive payload/range data and payload calculations, but for now, that's the way it is.

 

I just verified the (data-collector-entered) max fuel ranges of all 777 models in the game against Boeing specifications and found them to be correct:

 

The 777-200LR with 3 aux tanks has a max fuel range of about 10450 nautical miles, which is 12083 statute miles. In AE it's 12080 statute miles.

The 777-300ER has a max fuel range of just under 8500nm, which is 9782mi. In AE it's 9825mi.

The 777-200 has a max fuel range of 7000nm, which is 8055mi. In AE it's 8055mi.

The 777-200ER has a max fuel range of 9600nm, which is 11048mi. In AE it's 11025mi.

The 777-300 has a max fuel range of 8350nm, which is 9609mi. In AE it's 9609mi.

 

The "weird" numbers you're seeing are either:

 

1) estimated max payload ranges that don't match real-world payload/range charts (this is a game limitation as explained above)

2) stale data in older game worlds (range is never decreased in the middle of a game, so any data updates that decrease range will not take effect until the next reset)

Well, okay, the game has its limitations, but I don't understand why must total max fuel range be the measure in AE3 when 90% of players put either maximum economy seats or max-2 or max-3-class? Why not rather tweak the max range numbers to fit into max load range, just for the while until the engine is reworked??

 

Now the 777-300ER seems to be useless compared to -300 -.- ... so we got another miraculous fantasy plane similar to 737-600.

the f, now 787-8 also has 1300 mi longer full-load range than it should have...

So I hate to sound snarky or otherwise ungrateful at the work everyone at AE does, because I most certainly I am quite grateful for the work everyone does here, but are we actually going to do anything about the range calculations in game? Because as it stands the max-payload range of the 777-300is literally off by 3,000nm according to those charts. (4,300nm in real life vs. over 7,300nm in game)

at first thanks for the range updates. now are some aircrafts having a reasonable range, like the concorde and the a340-500. But now compared to the B747 range, is the a380 range now a bit short? qantans flys syd-den, and the a380 is for this quite much "under range", and on the other side, the b747-400er can do it without any limitations, but in reality this wasn't the case.... is this prob a mile/nautical mile mistake?

but still thanks for your work :)

it wondered me too but when i think about this...

what´s your problem? they have bigger not smaller range all routes that are flown with this aircrats in RL can be flown in AE too with this aircrafts...

it can stay so and i thik it is a lot of work to chgange the range from so much important aircrafts and many airlines will have prolems with this

All aircraft are being updated in good time, my friend, I've done the whole 747 series recently.
