Introduction

The FF-5 is a 3 1/8” sunlight readable color display instrument intended for efficient monitoring of fuel related information

for single or dual fuel tanks. The FF-5 has many display configurations based on single/dual flow senders, single/dual

level senders and a fuel pressure sender.

Full functionality is available with a fuel flow and level sender or only with a fuel flow sender using calculated fuel levels

based on fuel usage. Differential fuel flow calculations are also supported for fuel return systems. Fuel injector systems

are also supported. Standard automotive fuel level senders can be used, even with odd shaped tanks due to a

comprehensive, multi-point calibration system. Most fuel flow senders can be used as the K-factor of the sender can be

entered into the system for simple calibration.

MGL Avionics supplies a lightweight dual range fuel flow sender that is ideally suited for the FF-5. Fuel flow senders from

other manufactures (e.g. Floscan) are equally suitable.

In addition, the FF-5 can use the actual ground speed from a RS232 NMEA enabled GPS receiver to determine fuel

range.

The FF-5 can also be interfaced via the CAN bus to an external RDAC unit (Remote Data Acquisition Computer). This

allows for easier installation as the RDAC unit is normally mounted in the engine compartment.

3.9 Enter cruising speed (Mode dependent)

Press the F1 key during the main display screen to manually enter your aircraft’s cruising

speed. This value will be used to calculate the fuel range, i.e. how far you can fly with the

remaining fuel at zero wind speed. For this calculation, your current remaining fuel, your

current fuel flow and the speed entered here are taken into account. You can easily

change the speed during flight to reflect changes in ground speed or cruising speed. Use

this function with care and do not use it to extend your range. You must at all times have

a secondary indication of available fuel. Note that flow senders and level senders may be

subject to malfunction that may result in incorrect fuel levels being displayed or

calculated. This function is only available in certain display modes.

3.10 Enter starting level of fuel tanks (Mode dependent)

Press the F2 key during the main display screen to manually enter your current fuel level

after fueling or defueling your aircraft. This function is only available if you have a mode

selected where fuel level is calculated from fuel flow. Press the F2 key again as a “quick

fill button” to the full level.

Note:It is good airmanship to take into account a “silent” fuel reserve. For example, if you

have a 50 Litre tank and you fill it, enter 40 or 45 Litres as your available fuel.

3.11 Fuel Totals (Mode dependent)

This display can be accessed by rotating the rotary control during the normal display

mode. Press the F1/Up button when the fuel totals display is showing to reset the

totalisers.

These are 2 independent accumulators for fuel tank 1 and fuel tank 2 that totalize the

amount of fuel burn since the last time the accumulators were reset to zero.

3.12 Incorrect fuel setup message

The following message will be displayed if the FF-5 is incorrectly setup. For example if

both fuel flow senders are disabled and a single/dual fuel level(s) are setup for calculated

fuel tanks.

4.2.1 Tank 1 / 2 Setup menu

Fuel level setup. (Only tank 1 setup is shown, follow the same steps

for tank 2 setup)

Tank:

Select if fuel tank 1 has a physical fuel level sender connected to it or if the FF-5 must use a calculation based virtual fuel

tank. If you do not want any fuel level information then set this parameter to off.

Tank Size:

Enter the size of the fuel tank in your system. It is recommended to choose a size that is slightly less than actual size so

you can compensate for sender inaccuracies and give you a measure of reserve fuel.

Low Caution:

Enter the fuel level value for your fuel caution. Note that the fuel caution level will be displayed as a yellow bar on your

fuel level display.

Low Alarm:

Select whether to turn the fuel tank 1 low level alarm on or off.

Low Alarm:

Enter your desired minimum fuel value that you would like to trigger the fuel low alarm. The fuel low alarm will result in the

flashing of the fuel level display and remaining fuel readout. You can also connect a warning lamp to the external alarm

output (see installation diagram). Note that the fuel low level will be displayed as a red bar on your fuel level display. This

level is over and above your “silent” fuel reserve.

Add To Range:

Select whether this tank adds to the fuel range calculation

Calibrate Tank:

See section 4.2.2 on how to calibrate the fuel level senders.

Tank Filter:

Select the damping factor for the fuel level. A selection of none, low, med or high can be made.

Litre Res:

Select the resolution of the Litre unit. 1L or 0.1L
