SkyView Pilot’s User Guide - Revision M
The
Flight Trip Timer
- labeled
FLT TRIP
when displayed on an Engine Page -runs any time that
SkyView determines that the aircraft is in flight, just like the Total Flight Timer. Unlike the Total
Flight Timer, it can be reset by pressing ENGINE > CLR TMR.
Fuel Computer
The Fuel Remaining, Fuel Used, Fuel Efficiency, Fuel at Waypoint, and Range values
are not directly measured. These values are calculated based upon measured flow
rates and
user input
of fuel quantity. Do not use these values as primary indicators.
By using the optional fuel flow sensor and GPS information together, SkyView can generate and
display different info items that pertain to your aircraft’s computed fuel state and performance.
They are available for placement on the Engine Pages via the Screen Layout Editor. For more
information regarding the Screen Layout Editor, reference the SkyView System Installation
Guide.
The Fuel Remaining info item displays the current amount of fuel computed on board, based on
your input of the aircraft’s starting fuel state and the amount of fuel that has the fuel flow
sensor has seen flow through it.
The Fuel Used info item displays the amount of fuel that has been used during your flight. Note
that Fuel Used resets itself when the unit detects that oil pressure has exceeded 15 PSI for the
first time after being powered on. This allows you to view the fuel used value from your last
flight before engine start.
The Time Remaining info item displays how much time is estimated remaining before the
aircraft is out of fuel.
The Fuel Efficiency info item displays how efficiently the aircraft is using fuel with respect to the
speed it is traveling over the ground (mi/gal, kt/gal, km/ltr).
The Fuel at Waypoint info item displays how much fuel will remain at the next waypoint. This
info item uses the current HSI navigation source for waypoint information, and only displays
information when there is a waypoint being navigated to. It assumes you are flying directly at
the waypoint and does not adjust for non-direct flights.
The Fuel Range info item displays the distance the aircraft can travel at its current GPS ground
speed before it is out of fuel.
Fuel Menu (Adjusting the Fuel Computer)
To obtain accurate data, you must reset the fuel computer every time you add fuel
to the aircraft. SkyView can assist with this through the Fuel Auto Detect setting
described in this section.
