FlightSaver User s Manual To get a general idea of the functions provided by the FlightSaver it may help to review the FlightSaver brochure before reading this document l The Main Display Screen The most important information displayed by the FlightSaver appears on the main display screen so no button pushing is required The main screen is organized as follows Fuel Totalizer Hottest CHT 2 hottest CHT A typical fuel totalizer display looks like this eee oe ee e ee e ee e ee e 3 cooo eo ph ee oe 3s se e e e ga 00009 e oe e oe e eecoe e e eecccee e eccce e 2 8 e e 8 i e aa of ee 3 oo ar ee oe e eco oo k e eo eeoee o This means that The current fuel flow is 10 24 gph the last digit is smaller since it is rarely important There are 76 3 gallons remaining For more than 100 gallons the tenths are not shown You will be able to fly to the currently selected GPS waypoint and 4 2 hours more before the fuel is exhausted assuming the current power setting course and winds remain constant The letter signifies Reserve If you have not entered a GPS waypoint the display shows the hours of fuel currently remaining in the tanks followed by the letter i signifying Hours remaining A typical CDI CCI display looks like this The upper part is the CDI course deviation indicator In this figure it is showing a full scale 5 nm deflection to the rig
