5.3.2. Fuel planning

Fuel can be added to any stage and any tank by adding a figure in the right-hand (green) field.

In the above example there is currently 26 USG on board. To fill the tank full of fuel:

• tap in the green field
• type in 56 (no need to enter USG or LT etc)
• tap the Return key.
  

If a higher figure than the maximum size is entered, the row’s text will turn red.

Also, if you haven’t got enough fuel on board to complete the stage, the text in the Margin row within the fuel table will turn red.

Extra fuel requirements

Within the fuel planning table, there are several fields that details can be amended or entered.

This includes the Holding row, the Approach row and the Taxi row.

For example: If you’d like to add 30 minutes holding fuel, type 30 in the Holding row. If your aircraft burns 2 USG for startup and taxi, enter 2 in the Taxi row.

*Fuel is burned from top to bottom in the order the tanks appear in the load stations list.

To alter the fuel tank burn order, rearrange the order in which they appear within the Weight and Balance section within the aircraft type profile. Tap Settings > Aircraft Type Database > [your type] > Weight and balance.

Multi-Stage Refuelling

Any unused fuel for a stage in the plan automatically appears as the tank contents for the next stage. Swipe the page from right-to-left to view the loading and fuel for the next stage. Do the same again to view Stage 3, and so forth.

The unused fuel can be amended accordingly if you are planning to add fuel at that particular landing point. Simply amend the figure(s) to the amount of fuel you will have on board after refuelling the aircraft.

Changing the fuel units

If your aircraft profile is currently set up with the wrong units you wish to operate with (i.e. it’s in USG rather than litres, or LBS rather than KG), you can use the setup shortcut button in the top-right corner.

Select the correct units by tapping the Fuel units row, then placing a tick next to the correct one. Dismiss the menu by tapping away from it.

There’s no need to alter the setup figures, as AvPlan EFB always stores the figures in a standard unit, then displays whatever is selected.

*If you wish for AvPlan EFB to automatically enter a standard fuel state (e.g. full fuel, or tabs, etc) and the correct taxi fuel, they can be set as a default for that aircraft.

Margin Time

Margin time in minutes is calculated based on the margin fuel being burned at a rate equal to the weighted average of the planned climb and cruise burns. This is more conservative than simply using the cruise burn rate.
