Oat, Flight Time, Fuel; Direction Indicator - Kanardia Nesis III User Manual

Nesis III User's Manual
• The endurance is a derived value based on the available fuel quantity,
average fuel consumption (depends on the fuel computer mode) and
endurance reserve. It represents the engine time left assuming average
fuel consumption. At the bottom, specified endurance reserve is shown.
Once the reserve is reached, the range and endurance text are shown in
red and the reserved endurance remaining is shown.
• Range is a derived value, which is based on the available fuel quantity,
average fuel consumption, current ground speed and the specified en-
durance reserve. Once endurance reserve is reached, range is zero and
it is shown in red.
When no fuel level probes are connected to DAQU, Nesis provides a simulated
fuel tank where Nesis calculates the available fuel based on the information
entered before the flight or updated during the flight. The fuel level is reduced
by subtracting the fuel flow integrated in time. Both, the initial information
and the fuel flow integration, may be source of significant error, which can
quickly lead to a completely wrong fuel level indication. An indication higher
than actual represents a dangerous situation, where the fuel computer displays
more fuel than it actually is. This gives wrong and unsafe information to the
pilot. Therefore, the pilot must frequently compare the fuel level indicated by
the fuel computer with the independent external fuel gauges and indicators
and update the Nesis fuel level.

OAT, Flight Time, Fuel

The fuel computer window can be replaced by OAT, flight time, time and fuel
quantity information. Illustration of this window is given on Figure 26.
