3 Microflo-L ™ Although not required by the FAA, it is recommended that this manual be attached to th e FAA-a pproved Flight Manual, or always kept on board for reference. 1. GENERAL DESCRIPTION Microflo-L™ is a Digita l Fuel Management System designed to provide complete fuel management information under real flight conditions without any manu[...]

4 1.1 THE SYSTEM PROVIDES 1.1.1 SPECIFIC RANGE Specific Range (NM/GAL) = Ground Speed (Kt.)/Fuel Flow per hour. This is an indication of how efficient the cruise is and the optimum cruise speed can be determined by selecting the power setting, which yields the highest nautical miles per gallon. 1.1.2 FUEL TO DESTINATION Microflo-L™ calculates (un[...]

5 1.1.5 FUEL FLOW The system provides a digital re adout of the fuel per hour to a tenth of a gallon up to 100 gallons and to the nearest gallon above 100 gallons. For the pounds version, the readout is to the nearest pound up to 999 lbs./hour and to the nearest 10 lbs. above 999 lbs./hour. 1.1.6 FUEL USED The system keeps track of the fuel used si[...]

6 1.2 SYSTEM COMPONENTS The system consists of three (3) basic units: the fuel flow transducer, the navigatio n receiver (Loran-C or GPS) and the panel mounted unit. 1.2.1 FUEL FLOW TRANSDUCER The fuel flow transducer mounted in the fuel line measures the flow of fuel and genera tes electrical pulses directly proportional to the fuel flow. The tran[...]

7 1.3 TEST FUNCTION Diagnostic software is built into the system. To activate it, press the ENTER/TEST button until all of the display digits fill with a checkerboard pattern, and then release it. This display will flash on and off three (3) times. Next, all digits will be filled with a second checkerboard pattern, the inverse of the f irst, which [...]

8 2. PREFLIGHT PROCEDURES MICROFLO-L is a fuel flow measuring system and NOT a quantity-sensing device. A visual inspec tion and positive determination of the usable f uel in the fuel tanks is a ne cessity. Therefore, it is imperative tha t the determ ined available usable fu el be manually entered into the system . 2.1. INITIAL PROGRAMMING The fun[...]

9 6. After reaching the correct total usable fuel figure, press the ENTER/TEST button and the comput er will store that number as full fuel. The word “ FUL” disappears and the com puter will return to the opera ting mode. Release the ADD/FULL toggle switch. 7. To verify that the data is stored properly, pres s the ENTER/TEST button. The comput [...]

10 Move the USED/REM toggle swit ch to the REM position. The system will display the fuel rem a ining on board. The pilot should confirm this figure with the actual fuel on board. 2.3 NO FUEL ADDED This automatically stores inform ation concerning previous fu el levels, even in the case of a pow er down. If no fuel is added, no action is needed in [...]

11 2.5 PARTIAL FUEL ADDED There are two methods to enter partial fuel: Ramping Method Add the amount of fuel from the refueling m eter to the amount of fuel remaining. Enter the total using the following steps: 1. Move USED/REM toggle switch to REM position and hold. 2. Press and hold ENTER/TEST button to increm ent fuel remaining until figure to b[...]

12 switch in the USED position and u se the ENTER/TEST button to control the decrem enting. Note: Adding or subtracting fuel by any method resets the fuel used value to zero. 3. INFLIGHT OPERATIONS 3.1 INSTRUMENT OPERATION 3.1.1 FUEL FLOW For Single Engine Aircraft: FUEL FLOW is displayed continuously on the left display window. For Twin Engine Air[...]

13 3.1.5 NAUTICAL MILES PER GALLON Nautical miles per gallo n is selected by rotating the rotary switch to the NM/GAL position. The inf ormation is shown on the right display window. 3.1.6 FUEL TO DESTINATION Fuel to destination is selected by rotating the ro tary switch to the FUEL TO DEST. position. The information is shown on the right display w[...]

14 3.2 WARNINGS 3.2.1 NOT ENOUGH FUEL When the rotary switch is in FUEL TO DEST. position, the information in the display window flashes if fuel on board is insufficient to reach either th e destination se lected as the active waypoint or the final dest ination (if that total distance record is provided in the seri al message). Display window shows[...]

15 3.3 BRIGHTNESS CONTROL The display brightness is cont rolled by the BRIGHT/DIM toggle switch. Moving the BRIGHT/DIM toggle switch to BRIGHT repeatedly will make the disp lay brighter; moving it to DIM repeatedly will dim the display. Th e default brightness after power up is full brightness. 4. EMERGENC Y PROCEDURES In case of electrical power f[...]

This refers to Error 1, Group 1. The flow m eter will not continue to function after this point, and will continue flashing E1 , alerting the flow meter must be serviced[...]

17 6. CONFIGURATION DATA ENTRY Manual Entry Mode Ordinarily, the fuel flow indicator has been set up by the factory to match the K-factor of the supplied transducers and other set-up information. However, there are built-in provisions to change the set-up. Please be sure to define and document initial set-up before attempting to make changes. Overv[...]

18 Group 1: Generally, Group 1 is set up by the distributor and contains information defined by the part number. However, although functions are defined here , do not change them without proper knowledge or they will affect perform ance of the indicator. Group 2: Group 2 must be set up by programming the unit in Manual Entry Mode . Group 2 settings[...]
