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 (under real wind conditions) the

fuel necessary to reach the destination as selected on the

Loran-C or GPS receiver by multiplying the fuel flow by the

estimated time en route to the destination. (If an

intermediate waypoint is selected for navigation purposes,

the displayed fuel to destination represents the fuel needed

to reach the intermediate waypoint unless the distance to the

destination is in the serial message.)

1.1.3 FUEL RESERVE

Microflo-L™ calculates the amount of fuel which will be

available on board when the aircraft reaches the destination

or waypoint indicated on the Loran-C or GPS receiver. This

feature provides the pilot with accurate information so that

the reserve fuel situation can be evaluated and action can be

taken if necessary. (If an intermediate waypoint is selected

for navigation purposes, the displayed fuel reserve

represents the fuel reserve at the intermediate waypoint

unless the distance to the destination is in the serial

message.) Fuel Reserve = Fuel Remaining – Fuel to Reach

Destination.

1.1.4 ENDURANCE

Microflo-L™ calculates the time left to fly in hours and

minutes based on the fuel remaining and the present fuel

flow.
