of 257,895 Lbs of fuel. With a full load of fuel the MD-11 is capable of flying over 8,000
nautical miles. One gallon of Jet A fuel weighs approximately 6.70 lbs.
Range: 7,200 NM
Fuel Burn Rate Factor: 31.6 lbs/NM
Fuel Base Amount: 40,000 lbs
Fuel Loading Formula: (Fuel Base Amount + (Distance * Fuel Burn
Factor)) Calculation of this formula gives you the correct amount of fuel for
your trip.
As an example, for a 2000 nautical mile flight leg the Fuel Loading Formula
would be (40,000 lbs + (2000NM x 31.6)) = 103,200 lbs. Please note that
this does not take into account the 45 minute reserve required; approximately
15,000 lbs.
To load fuel into your aircraft, select Aircraft, then Fuel and place the correct
fuel amounts in the correct tanks.
Look at three typical flight examples:
KMCO (Orlando, Florida) to KATL (Atlanta, Georgia) 450 nm would require
approximately 54,000 lbs of fuel.
KATL to EGLW (London-Gatwick, United Kingdom) (NAT route) 4,000 nm would
require approximately 166,000 lbs of fuel.
KLAX (Los Angeles, California) to NRT (Tokyo-Narita, Japan) (PACOT route)
5,200 nm would require approximately 204,000 lbs of fuel.
Captains ordering fuel for Delta Virtual Airlines flights should remember that more fuel
equates into more drag, requiring more power. An unnecessary overabundance of fuel
will only cost the company money. Fuel should be kept as close to the trip fuel required
as possible. With that said, it is always the pilot's responsibility to ensure that
there is enough legal fuel for the flight. Any incident that was the result of miscalculating
the fuel load will always be the fault and sole responsibility of that flights
captain and crew. When in doubt, take more.
Delta Virtual Airlines aircraft shall always carry a minimum fuel load for the trip to the
destination, and at least 60 min reserve in cruise at low altitude (Fuel Base amount) plus
a 45 min reserve for diversion to the designated alternate landing site.
Any trip estimations that you see in this manual are for calm winds and standard outside
air temperatures. Deviation from standard winds or temperatures will result in different
actual performance for your aircraft. When flying over long bodies of water, remember
that in the event of pressurization problem or an engine failure that requires descent to
14,000 feet MSL for passenger comfort, the fuel burn for the aircraft will increase
significantly and may leave you short of your initial destination. Plan accordingly!

TIP: This equation doesn’t consider wind. This is of special importance when crossing
the ocean. If you fly Atlanta-Gatwick with the fuel indicated by the equation you will
reach destination with enough fuel to fly to your alternate. By contrast, flying Gatwick –
Atlanta, you will be having strong head winds, and this equation will surely leave you
short on fuel. This is a quick way to crosscheck the fuel quantity. At cruise, the average
fuel consumption of the iFDG MD-11 is 2,800 Kg/h per engine. This is approximately
6,200lbs. The total average is 18,600 Lbs/h. Now you should go to the timetable and
check the estimated flying time and multiply the hours by 18,600. That leaves you with
a rough estimate for you flight. The following procedure should only be done when
flying long flights with strong head winds.
Example:
Frankfurt to Atlanta. Approximately 10 hours. 4053 miles.
The equation: (40,000 + (4053 * 31.6)) = 168,075 lbs.
Now, we multiply our average fuel consumption by the timetable flight length.
18,600 * 10 = 186,000 lbs
In this situation you can see that there is a big difference between the values, if you
would have loaded the fuel given by the first equation, you may have been short. Other
than this situation the equation works fine, the problem is when you have a long flight
with strong head winds. These winds will make your fuel consumption increase greatly.
