3.4. Rotor mode profiles
A profile configures the user interface for a particular type of aircraft or
scenario. Each profile specifies a few values that can modify how jobs are
displayed. Profiles can currently contain these values:
sensorOffsets An array of four values that specify the angle offsets
(rotations) of the accelerometer axes (X, Y, X2, Y2) from
the datum position. The datum position is normally taken
to be when the master blade is pointing forward. Having
a non-zero angle offset for an axis will rotate the polar
points for that axis around the centre of the chart in a
clockwise direction.
tachoOffset The angle the rotor sweeps through between the rotor
position when the tacho triggers and the rotor position
when the master blade is in the datum position. If the
tacho and the tape are aligned when the master blade is
in the datum position, this angle will be 0. Having a
non-zero tacho offset will rotate all the points around the
centre of the chart in an anti-clockwise direction.
If a second accelerometer is mounted near the front of the machine, it is
expected to be orientated such that its X axis is pointing to the right and its
Y axis is pointing vertically upwards.
The following table lists the supplied profiles. The user can also define their
own profiles (see Appendix B ).
tachoOffset sensorOffsets Description Profile Name
0 [0, 0, 0, 0] A profile that doesn't have any
effect.
None
0 [90, 0, 90, 0] These profiles are currently all
identical. They all set
Standard,
AutoGyro, ELA,
Magni sensorOffsets so that the X
and X2 polar points rotate 90°
clockwise on the chart. This is
applicable when the
accelerometer mounted on the
mast is orientated such that
its X axis is pointing
horizontally to the right and
the Y axis is pointing
horizontally forward. This is
the standard accelerometer
orientation recommended by
