Running out of fuel 737-800 whats the procedure?

Hi guys was on a flight last night mostly across water, when i suddenly realised that at the rate i was burning fuel i wouldn't make my destination and in fact would be lucky to make any land at all - I'm running with FSPassengers 2016 with instant save on, so actually really cared about saving my pilot and aircraft, so panic began.

 

so i proceeded to cancel my IFR with ATC, and gain as much altitude as i could getting up to 35,000ft  to give me as high glide slope as i could once power went.

 

looked at my GPS and changed course for the nearest land while trying to find my nearest airport, sure enough there was one at the island i was headed for.

 

anyway pretty soon all engines stopped and in order to keep up air speed i started my decent, in actual fact as it happened i had to circle three times in effort to lose altitude and speed to be able to land safely come the end!.  However my biggest challenge actually came when all the power went off, literally everything. switched off about 5 mins before i needed it all to land. i clicked for the APU to come on but nothing happened i thought this would buy me a little time with electrics, but it didn't.

 

so my question, could I of done anything better in this situation? I considered shutting one engine down when i realised i was low to safe fuel but then with the drop in speed would i have gained anything ? i was cruising at mach .78 at 31,000 feet when I knew i wasn't going to make it. i went for keeping the speed up and gain altitude.

 

also when the power went could I of done anything to get power / or save power  ?

 

I was in default 737-800, but with Advanced VC cockpit from rikoooo and I'm using P3D for what it matters.

 

I have googled this, but find most people are questing the range of the 737 on FSX / P3D where as i want a procedure once you run out. . 

 

anyway thought this would be a fun topic of conversation .. :)

 

oh yes saved the plane,  pilot and all passengers after a lovely smooth but slightly fast landing after pumping Ctrl G to get the gear to come down lol . . .;)

Hi uksfpred,

 

I have no real or virtual experience managing a 737 that has run out of fuel, I suspect that the flight was mismanaged by your co-pilot (a strong reprimand is in order). You should have enough fuel onboard for an alternate field and 30-40min of fuel for weather & holding pattern approach.  You could just open the back door and remove some of the cattle class passengers, or open the realism settings to check unlimited fuel or adjust the fuel and payload on the fly, so to speak.

 

I saw a movie once where the plane was running low on fuel over water at night, they weren't going to make land, they were over weight and under fuelled. I Cant remember the name of the movie but it had all the usual drama of a 1930's classic (killer with a gun, an alcoholic that couldn't wait to end it all, a pretty curvaceous blond, a sick child, a war hero, a pilot with a faultless record, and a cop), it was an old 2 engine Viscount or something like that. If I remember the plot, they threw out all the luggage, then the old and infirmed, then the seats that the remaining passengers did not need, then the co-pilot, they made it to the threshold with some losses.....  (Well wadyyaknow) the pilot saved the plane and the pretty blond, a heroes welcome.

How you could have improved it? Before the flight ever left the ground, by assuring you had enough fuel for the route, alternative, and reserve. You need to take en route weather, headwind component and so on into account when loading fuel. You should plan your fuel load to land with at least your final reserve on board. I do not know of any specific procedure: "What to do if you do not plan enough fuel for your journey".

but shouldn't I of been able to turn the APU on to give me power again ? even if for a limited time ?

 

and yes I will plan better next time! . . . i couldnt make any changes to the fuel mid flight because I didn't think FSpassengers would allow it due to the reaslism settings

Some aircraft used to have an wind blow generator that you could extend into the slip stream in the case of generator failure. The 737 is not so equipped. You could have gotten some juice from the batteries through the standby power but I do not think the default 737 would model that. I wonder if you used more fuel in the climb that you would have used holding altitude until the you lost power and gotten closer to land. However you landed so you were correct. I think you check list should have been:

 

1. Pray

2. Bend over grab your ankles and kiss you A-- goodbye.

3. If you survive kiss your airman's certificate goodbye.

APU won't work without fuel so you would have deployed the Ram Air Turbine (RAT) to get hydraulics and on some systems power, as you are using the NGX it doesn't use a RAT so this system is missing. Reason for this is the 737 is smaller so the pilot will muscle the controls and battery will provide some basic power, this will make for an extreme white knuckle landing with heavy controls and limited systems (It is kind of like your steering wheel on your car with no power steering when the car is off, the steering becomes heavy).

 

On other aircraft this is a description of the RAT:

Edit: When deployed the RAT makes a very loud humming noise and adds to the fear factor for the passengers who would know very little of what is happening

Interesting scenario. I am not a tube liner pilot, so I do not have much to offer other than a pat on the back for getting your aircraft and simulated passengers down safely. I am a GA flyer, and only a simulated one at that. I do on occasion fly the venerable A2A B-17 G Flying Fortress, but that is as large as I will go, and the systems in that fine plane are nothing at all like what you are dealing with in a modern 737. My ONLY question is similar to what Greg said above. That is I wonder how much fuel you used gaining more altitude vs. staying at your current cruise altitude.

 

But, all in all, you made it, so a big thumbs up! Oh, and I agree with several of the others on the better planning comments. ;)

Brilliant I just read both those links. I

 

interesting how an experienced crew didn't check that the fuel imbalance was not caused by a fuel leak before opening the cross-feed valve :o

 

 

Would you not get a little suspicious when Engine one has X hundred's of gallons left and engine 2 has none ?

You shouldn't have climbed once you realized you were facing a fuel starvation issue. That just 1) Burned more fuel and 2) Made your powerless descent more challenging.

 

Didn't your FMC show well ahead of time that you weren't going to make your destination?

True story...

 

A friend of mine in Northern Australia has a Cessna and when he does cross country he lands it on the road and pulls into a gas station to refuel. On this one occasion he landed and pulled into the gas station to find a police cruiser at the gas station. Officer didn't like what he did so he wrote him a ticket for driving an unregistered vehicle on an Australian Highway.

I have run the default 738 and 744s out of fuel several times, but I cheat!:huh::o:lol:

 

I have never realised just how many extras they have to allow for as this interesting clip explains.

Lucky he did not land in Victoria or they would have booked him for speeding too!
