What is fuel bias?
Fuel bias is as you described it. As the engine ages, it burns more fuel than a brand new one. The fuel flow (and drag) corrections are entered into the FMS. This would allow the FMS calculated quantity not to disagree with the tanks totalizer. The figures are based off previous flights and engine tests.
How is aircraft fuel contingency calculated?
In general terms, the minimum contingency fuel is the greater of 5% of the trip fuel or 5 minutes holding consumption at 1500′ above destination airfield elevation computed based on calculated arrival weight.
What is fuel bias JB4?
This bias allows the JB4 to effectively change the air/fuel ratio target. A higher bias means a richer targeted air/fuel ratio. And the DME will generally hit its air/fuel target provided the fuel trims are within range.
What is DME BT?
DME BT is the factory boost target and the JB4 can’t change that. So if your DME BT is lower it’s the factory programming requesting it.

Is Min fuel declaring an emergency?
This is not an emergency situation but merely an advisory that indicates an emergency situation is possible should any undue delay occur. A minimum fuel advisory does not imply a need for traffic priority.
How many miles will 5 litres of petrol do?
We have converted 5 Litres per 100 kilometres to 56 Miles per Gallon.
How much fuel does a 25 hp outboard use?
As a point of departure on the search for an answer; there is a rule of thumb that outboards consume about 1 gallon per hour for every 10 horsepower. That equates to roughly 2.5 gallons per hour at full throttle with a 25 HP motor. You will hardly ever run your motor at full throttle for an hour.
What does JB4 stand for?
JB4 is a piggy back system for tuning, basically controls engine paremeters from the ECU to the Engine. Its a rather dirty but functional way to tune a car. Many short comings to a piggy back system that are often overlooked due to the ease of installation and removal.
What do you mean by ” fuel bias ” in aviation?
Airbus and Boeing seemed to have different terms for this, PERF Factor, Fuel factor. The seem to be close in definition but I’m not really sure. Fuel bias is as you described it. As the engine ages, it burns more fuel than a brand new one.
How are fuel biases entered into the FMS?
Fuel bias is as you described it. As the engine ages, it burns more fuel than a brand new one. The fuel flow (and drag) corrections are entered into the FMS.
Are there any biases in a flight plan?
There are also “biases” to consider, depending on the make and model of aircraft. For example with Gulfstream aircraft, our flight planning experts typically add a 16% bias for flights of less than three hours. However, biases depend on the age of the aircraft, how the operator flies it, planned flight level, and speed.
