Make sure the
Airspeed Sensor
is working, before using features that require a
minimum flight speed to operate. If the system is not operating properly, you may
inadvertently shut off your engine, in flight. To verify that the
Airspeed Sensor
is
functioning, apply a little air pressure and note the change in “
Airspeed
” on the
run
menu display.
Two examples:
Example 1 –
Hold-Speed
function
SpdCtrl SW0 Act
assigned to “
Hold-Speed
” and
AUX
switch set in the
SW0
position:
1. Flight speed is measured and stored, when the
AUX
switch is moved to the
SW0
position. Thrust is then regulated automatically, to maintain this memorized
speed, despite the throttle stick position. This regulator function is turned off
immediately, by returning the
AUX
switch to the
SW1
position (normal
thrust
control
).
2. If this function is activated while flight speed < 40 km/h, turbine will shut off,
immediately (normal
Off
function).
Example 2 –
Linear speed
regulation
SpdCtrl SW2 Act
assigned to “
Lin-SpeedCtrl
” and
AUX
switch set in the
SW2
position:
Cruise Control
mode becomes active, featuring linear speed regulation to the throttle
stick position.
1. The minimum throttle stick position corresponds to the parameter “Min AirSpeed”
and the maximum throttle stick position corresponds to the parameter “Max
AirSpeed”.
2. If flight speed < 40 km/h when this function is activated, the turbine will shut off
(normal
AutoOff
function).
Airspeed Sensor Mounting:
Experiments indicate that the
Airspeed Sensor
is more accurate when the pitot tube is
side-mounted on the widest part of the fuselage. In this configuration, the pitot tube
should stand off from the fuselage, by at least two (2) inches. Because each model
installation is different, JetCat will have additional mounting information for review, as
auxiliary data becomes available.
