Is refueling modeled in aircraft delays?
« on: August 06, 2019, 07:44:11 AM »
For example:   Aircraft A and B fly the same routes.  They are config'd to carry 19 passengers each.  Both are using 25-minute turn-times.  However, aircraft A has a range of 340 nm (shorter if an IFR reserve is deducted from usable fuel...is it???) .  Aircraft B has a range of 1200 nm.  The average leg length is 165 nm. 

Recognizing there are other factors affecting range, for this example, Aircraft A would have to refuel after the first round trip, or 4 times for 4 daily round trips.  Aircraft B wouldn't have to refuel until after 3.5 round trips, or once for the 4 daily flights, theoretically allowing it to turn quicker.

Since both aircraft have the same minimum turn times and are both turning at 10 minutes more than their minimum, does the aircraft delay algorithm increase delays for an aircraft that MUST refuel more frequently than others due to its routing and usable range/fuel?

no.

I can't answer for Sami and whats in the code but I've never seen this mentioned and think it is at such a micro-level of detail that it is unlikely to be modelled.

usually refueling is not the time critical process during a turnaround, but to chase the pax out and back into the plane...

Also, generally aircraft will refuel far more often than they "need" to.  Just because aircraft B has a maximum range of 1200 miles, doesn't mean it will usually take off with enough fuel to do that. In fact it almost never would. It isn't like your car where you maybe fill the tank and then drive until the red light comes on. If aircraft B were flying a 165 mile route it would usually carry just enough (plus reserves of course) for what is required - or maybe enough for one round-trip. Anything else would be wasted weight being carried around, thus increasing overall fuel burn. Of course there are many other things that would influence this (Is the fuel a lot cheaper or very expensive at the other end of the route? Is it even available? How likely is a weather diversion? What are the takeoff/engine-out considerations at each airport, are there already delays requiring a quicker than usual turn?).In summary, the longer range aircraft will probably end up refueling almost as often as the shorter range one. Add this to the fact that the fueling is done at the same time as other servicing and it probably isn't worth modelling.

Thanks for the replies.  Things I hadn't considered.
