Minimum Fuel

IMHO, I believe that minimum fuel should include enough fuel for a go around from the flare, and, after declaring an emergency for fuel, fly an expedited ILS pattern and land with enough fuel for engine reversing and runway clearing. Not necessarily with enough to taxi to the gate.
If you don't have enough for the go around, then declare emergency fuel.

And too this will include some factors for the aircraft. Some machines will have cautions that at low fuel states, the fuel pumps may be uncovered and cavitate.

In the military - those fuels are often listed in a squadron (or HHQ) SOP. For instance - our NATOPS lists 1,500# of fuel on deck. If you think that you will be on deck with less than that amount - declare EMERGENCY fuel and expect that ATC will handle accordingly. Minimum fuel is a fairly loose term for us. We all learn about it but it isn't a hard number often times. It means that any undue delay will probably drive me into an EMERGENCY fuel siutaiton. We are briefed not to expect any special handling from ATC, but a smart controller/pilot team will realize what is going to happen soon and usually there is some action taken to prevent the situation from deteriorating further.

And yes, min fuel is a loose term and for that reason I am trying to determine what the average line pilot uses. That amount will vary but what does the average line pilot use for min fuel and what does s/he expect?
I have declared min fuel a few times and it was interesting how the controllers responded. One asked what airport was I diverting to.
Also, in the ASRs, there are some reports of controllers declaring flights as 'emergency fuel' when there was no declaration by the crew. ??

I am familiar with part 91, 135 and 121 for dispatch and the considerations for dispatch.
"The definition is in the AIM.
There is also no definition of emergency fuel in the FARs."
http://www.faa.gov/other_visit/aviat.../info08004.pdf
"What do you use for emergency fuel and how is that determined?"
Several factors, should be defined in your company's flight operation manual

Yes, I have the PDF from the FAA on my desk. But it is an INFO for operators and not an FAR.
[quote ]** This is where I became very suspicious:
"Situation:
You have been dispatched from KATL to KLAX. Your flight plan is for FL350 but due to turb/wx/ATC, you are initially given FL290. You are over VUZ (Vulcan) in Alabama, level at FL290. You run your fuel log and see that you will arrive at KLAX with min fuel. What do you do while over VUZ? (or if you want, EMB-145 KATL-KPHL.. and over GSO)
Where did you determine the flight level numbers going from Atlanta to Los Angeles? [/quote]
Suspicious of what? And FL350 is a relatively routine altitude for long distance flights and a fat 737 is not going to be much higher than that initially. I know on the Airbus we didn't get much higher than that initially.
So, what would you flight plan at? And as for the route, change it. Change it to CLT-LAX (USAir) or BUR-MHT (SW)and we will put you in a 737-NG with winglets and plan it at 380 but you can't get it due to moderate turbulence. SAN-ORD(United). I would suggest a BBJ but this is an airline forum. Does that make it better?

f you want something for the newspaper:
"Pilots' first concern is safety, the amount of fuel they carry to landing is based primarily on that with a degree or two of comfort level, experience, judgement and good business practices."
"Pilots' first concern is safety, the amount of fuel they carry to landing is based primarily on that with a degree or two of comfort level, experience, judgement and good business practices."
FWIW, with more than a few type ratings, experience in gen/av, military and airlines ops, I know what I think about min fuel and emergency fuel. I know what I will do but the story is not about what I think or will do. It is a sampling from the ranks. I don't need someone citing FARs and FAA info letters. I have that.

One problem with any minimum fuel planning is the trust that you really have the minimum fuel you are counting on. If you go around truly believing you only have enough fuel for an expedited ILS and not even enough to taxi in, can you count on your ability to determining exactly how much fuel you will burn to fly that procedure and, more importantly, do you trust the gauges to show how much fuel you really have.
Its one thing to base your TOGW on a company provided ZFW and add up the gauges. Its another to put your life, your crew and passengers lives on the line trusting that a gauge that reads 1200lbs really has 1200 lbs in it (especially when you've never seen less than than, say 4000 lbs on it).
Everyone has some true minimum level that that wont allow the fuel level to reach. Experience with holding, trusting ATC (or more likely not trusting) their EFC's, believing your companies fuel planning ,and harrowing tales of near (fuel) starvation, all play into our psyche of how little fuel you allow loading on your aircraft.
And do you frequently talk to your dispatcher before departing or do you just sign the releases and go with the planned fuel?

Again, there is a difference between planned and actual.
As I see it, there are (at least) three levels of ACTUAL fuel planning:
I hope this helps. Please feel free to add your thoughts...

Please keep the TCAS on TA/RA on that westbound flight at 350.

Why wouldn't it be okay if hard IFR? What is the reserve fuel?
Again it's a judgement call made in the moment, not by some journalist fishing for a story.

Was.
Actually line pilot first and writer second. I don't 'journal'. And for me it is a cockpit, not a flight deck to show how long I have been aviating.
It is not a matter of being treated professionally by ATC but I had not read or known of a flight being declared an 'emergency fuel' by a controller until I read through some of the ARSs.
And if I add my name or the magazine to the post, does that validate anything? At this point, let me say it is a known publication and I would not besmirch its reputation with a slam or goofy story.
If a reporter, investigative, etc. You should disclose. Personally would be suspicious of providing info and wacked in the press. Press doesn't like us to much. Anonymous promises are pretty weak unfortunately.
Also, ATC treats us very professionally and complies with the request from the pilots complying with all due regulations.

In the ASRs, pilots declare min fuel and then divert rather than continue to destination. ?? Also, some ASRs report crews are reluctant to declare emergency fuel and then some say nothing and then declare emergency fuel. The questions arise then as to why they didn't first declare min fuel.
The few times I declared min fuel, I had to decline 'best forward' and had to remind the controllers at times I was min fuel, especially when changing freqs. I am not disparaging anyone but there are gaps in the system.
As for FL350 being the wrong altitude, my error. I will file a NASA

I jumpseated a long time ago on Frontier, not the one now flying but the one with Convairs and 737-200s and we took off for ABQ on a short flight with less fuel than I wanted to land with. They were very comfortable with the fuel state. So yes, some companies operate thinner than others. And some Capts take lower fuel loads than others.
So what do you fly and what is your min?
And do you frequently talk to your dispatcher before departing or do you just sign the releases and go with the planned fuel?

As far as talking to dispatch. I'll do so when I feel they either could or should know something I don't have access to (big picture) or to educate them on something I think they either don't see from reports or believe they are too optimistic about. I've never had a disagreement, but than I haven't made a name for myself pushing (them) to give me fuel they didn't feel was warranted.
