What is the difference between minimum fuel and emergency fuel?
Declare “minimum fuel” when, in your best judgment, any additional delay will cause you to burn into your reserve fuel. Declaration of a fuel emergency is an explicit statement that priority handling by ATC is necessary and expected.
What is Mayday fuel?
The pilot-in-command shall declare a situation of fuel emergency ”MAYDAY FUEL”, when the calculated usable fuel predicted to be available upon landing at the nearest aerodrome where a safe landing can be made is less than the planned final reserve fuel.
What is the minimum fuel requirement for VFR day conditions?
Day: You need enough fuel to fly to your first landing point and then still have 30 minutes of fuel remaining at a normal cruise speed. Night: Same as above, but you need 45 minutes after reaching your first point. Helicopters: Same as above but you need 20 minutes regardless of day or night conditions.
How do you calculate minimum fuel?
For example, if a forward adverse condition check was being done on a piston engine powered twin, with each engine having a METO horsepower of 500, the minimum fuel would be 250 lb (500 METO Hp ÷ 2). For turbine engine powered aircraft, minimum fuel is not based on engine horsepower.
What is the minimum fuel reserve after landing?
Contingency Fuel / Route Reserve According to ICAO Annex 6, the recommended 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 holding fuel?
Holding fuel is a quanity of fuel which will permit an aircraft to hold for a time, at the holding fuel consumption rate and configuration, at a level not greater than Flight Level 200 at the forecast temperature.
When to use Mayday fuel instead of minimum fuel?
This situation is not yet an emergency and ATC does not need to give you any priority, but they know that keeping you in a holding pattern could result in you declaring an emergency. The term Mayday Fuel should be used when it is clear that you will land with less than the minimum fuel reserves.
When do you use the term minimum fuel?
The term Minimum Fuel should be used when you currently expect to land with more than the minimum fuel reserves (so everything is OK right now), but any further delay would result in being below minimum reserves when landing.
What does the declaration of minimum fuel do?
(PANS-ATM, Doc 4444) The declaration of “MINIMUM FUEL” informs ATC that, for a specific aerodrome of intended landing, the aircraft has sufficient fuel remaining to follow the cleared routing, execute an arrival and approach procedure and land with the required fuel reserves.
How long do you have to hold reserve fuel?
If the flight is planned without alternate, the final reserve fuel should be no less than 60 minutes holding fuel. Reserve fuel or Minimum Diversion fuel is the sum of Alternate fuel plus Final Reserve fuel.
