2.8.7.1 Electric engine Data
This menu is divided in two sections:
The Engine data displays, in real-time, the Throttle commanded to the engine, the main
battery voltage, the amperage consumed by the system and the wattage.
As different autopilots have different main battery channel assigments, a drop-down select
box is provided to select the proper main battery channel. This selector affects only the
wattage calculation and the graphical plotter of wattage against IAS.
A real-time plot of the IAS (Indicated Air Speed) of the plane vs the Wattage of the engine
can be shown with the Graphs button on this section. The IAS is shown on the horizontal
axis with unit indication in the right bottom corner while the instantaneous power is shown
on the vertical axis in Watts.
The Battery data section shows data about the battery capacity status: the information
shown corresponds to the mAh left on the battery, and the percentage of battery left. For
that it is necessary to set the maximum battery Amperage on the Max [mAh] box, before
the mission starts. With this data is possible to know the amount of consumed battery with
an error lower than 3%.
