## How is aviation fuel calculated?

The amount of fuel needed for a given flight can be calculated by multiplying the estimated flight time by the rate of consumption. For example, a flight of 400 NM at 100 knots GS takes 4 hours to complete.

## How do you calculate fuel takeoff?

Subtract the total amount of fuel you have on takeoff from the amount you will use during your flight. What will be your takeoff fuel weight? To calculate your takeoff fuel weight, multiply your takeoff gallons by the weight of fuel.

## 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.

## How is minimum diversion fuel calculated?

Minimum Diversion or Reserve Fuel is the sum of the Alternate Fuel and the Final Reserve Fuel.

## How much fuel does a helicopter use?

Now converting the fuel efficiency of the helicopter in kmpl, suppose if the helicopter is cruising at its 167 kmph speed and if it consumes roughly 8 gallons or roughly 30 litres of fuel per hour, then the answer comes out to be around 5.5 kmpl.

## How do you calculate takeoff speed?

Ask the Captain: How is takeoff speed determined?

- Question: When a plane is speeding down the runway, what determines when liftoff occurs.
- Answer: The speed at which the airplane lifts off is determined by the weight, temperature, altitude of the runway and the slat/flap setting.

## How much does Plane Fuel weigh?

Unless the specific weight for an item is known, the standard weights used in aircraft weight and balance are as follows: Aviation gasoline 6 lb/gal. Turbine fuel 6.7 lb/gal.

## How do airplanes calculate speed?

Mach Number:

- Formula: Mach Number = Aircraft Speed / Speed of Sound (dependent on altitude)
- Example: Aircraft is flying at 30,000′ Speed of sound at 30,000′ = 589.4 knots. The airspeed is 489.3 knots.
- Calculate: 489.3/589.5 = 0.83 Mach.

## What is minimum fuel in aviation?

Use of the term “ minimum fuel ” indicates recognition by a pilot that the fuel supply has reached a state where, upon reaching destination, the pilot cannot accept any undue delay. This is not an emergency situation but merely an advisory that indicates an emergency situation is possible should any undue delay occur.

## What is the minimum fuel reserve for day VFR?

General Aviation 3.6 ” Fuel and oil supply” requires: For IFR, enough fuel to reach destination, then alternate (if required), plus 45 minutes. For day VFR, enough fuel to reach destination plus 30 minutes. For night VFR, enough fuel to reach destination plus 45 minutes.

## How much reserve fuel does a plane carry?

For any instrument flight (IFR) 14 CFR 91.167 tells us we need a minimum of 45 minutes of fuel in reserve, which means the ability to fly all the way to the intended airport, then from the intended airport to the planned alternate airport and then an additional 45 minutes.

## What is alternate route?

En- route alternate: An alternate aerodrome at which an aircraft would be able to land in the event that a diversion becomes necessary while en route (may also be the takeoff and/or destination aerodromes).

## How do you divert in aviation?

THE Diversion Checklist

- Sync Heading Indicator.
- Fix your location.
- Note the Time.
- Turn on to an approximate Heading.
- Draw a Line and determine the Distance.
- Determine True Track.
- Assess the drift from the Wind Correction Angle.
- Determine the Variation.

## Which fuel is used in airplane?

Aviation kerosene, also known as QAV-1, is the fuel used by airplanes and helicopters equipped with turbine engines, such as pure jet, turboprops, or turbofans.
