Hello all,
Today in ground school our professor gave us an extra credit assignment to have by Monday. Someone over the Thanksgiving break was flying home, and their 737 did a missed approach due to snow-plowing equipment on the runway. The question we have to answer is: what is the cost of a go-around in a 737. Assuming that you don't fly the hold as published and instead just do the traffic pattern and land. The costs I can think of are fuel, pilots pay, and flight attendants pay. I'm sure I'm forgetting something.

What is the cost of Jet-A gas to begin? And then I'd need to know the average rate of fuel consumption.

Thanks if anyone can answer this by Monday!

Nick

you're forgetting extra wear and tear on the aircraft due to the extra time in the air.
Possible liability claims from passengers who were late for their thanksgiving turkey (though you might be able to pass those on to the airport).
Extra cost due to crew having to work overtime to handle the delayed aircraft (especially if it is the last flight of the day into that destination).

I just checked Airnav. Jet-A is doing $2.34 on average over the entire USA, with prices varrying between $1.05 and $4.50 a gallon.
Note that that is probably a spotmarket price paid mainly by small consumers (visiting businessjets, etc.) and airlines most likely get a good discount on bulk purchases.

Well, an acquaintence of mine flew his Twin Comanche into MCO to pick me up off a Delta flight; and I know he caused an American MD-82 to go-around because he didn't get off the runway in time. I don't think they just flew the pattern and landed; I think they had to be sequenced again; which hopefully we didn't cost them too much money...

I don't know the cost of a go-around in a 737 but I roughly know the cost of NOT doing a required go-around:

50-400 people dead
$10mm to $300mm in wrecked airplanes
$20mm to $100mm in airport downtime, rerouted flights, lost revenue
$500mm and up in lawsuits

I'm by no means qualified to answer this question, but I was hoping to respond exactly like ThirtyEcho did.

I think that is the only thing to think about when figuring the cost, what is the cost of NOT going around?

Amen ThirtyEcho, Amen. Considering the opportunity costs, a go-around should never be discouraged if one is needed.

Actually that was not the question asked, was it?

I emailed a 737 captain I know, he also happens to be #1 seniority for Continental at EWR on the 737. Here's his response:

Regarding your question about a go-around in a 737, let's consider in round numbers that it might take 500 to 1000 pounds of fuel (6.7 pounds per gallon; maybe 80 cents to $1.00 per gallon these days, depending on where you are) depending on whether or not you can just do an overhead pattern with the tower or get cycled back into a radar pattern with approach control. Yes, there is the crew cost per minute....I'd say a go around might add 10 minutes to 25 minutes onto the flight. My pay at Continental is $166 per hour. Maybe the first officer is $120 per hour.....I am really guessing here.....and the flight attendant pay something much less. Anyway, there is also maintenance costs that a factored in per hour, as the extra flight time on a go-around would put the airplane that much closer to the next scheduled inspection. There would be some maintenance cost per hour to consider as well as direct operating costs like the fuel and crew costs.

There might be other costs to the airline if the go-around resulted in mis-connecting passengers. You could probably extrapolate your problem and let it have various subcategories of consideration. If the prof only wants direct operating costs, you can probably do a credible job of estimating those. Realize the crew costs are much higher at a Delta, American, or United Airlines, by the way.

ThirtyEcho said it.

And, as for figuring out the cost of a go-around, you’re forgetting one of the most important things. The cost of write-offs.

Take the price of your airliner, distribute it over the time the airline expects it to pay off in. You’ll end up at quite a few dollars per minute.

Ever wonder why airlines don’t like having their aircraft standing around on the ramps? Stop wondering… they have to be up in the air making money or the write-offs will put the net income in the negatives every day. That’s the way the reflected sound of underground spirits (echo-gnomics) works in the airline business.

Cheers,
Fred



I thought I was doing good trying to avoid those airport hotels... and look at me now.

Aircraft are written off based on hours of flighttime, not callendar years.
So an aircraft on the ramp doesn't age (except due to possible weather of course, but that's covered under maintenance expense).

Apart from the loss of revenue when an aircraft isn't flying, the main cost factor of having an aircraft parked is the parking fees. At a major airport those can be huge for an airliner (hundreds to thousands an hour at really expensive airports for a 747).

If you asked my old boss, it cost about a million to do a go-around in a Baron. "Professional Pilots shouldn't have to do go-arounds" he said. Remind me why I don't work there anymore? And professional pilots shouldn't have 2 gear up landings, either. Oops, did I say that out loud?

And Jwenting, not being picky, but there are some time limited parts on aircraft. You're correct saying that the whole aircraft isn't "calendar year limited", but there are certain parts of them that are.
