Rev. 2.1
allowing only one left for the squat switch input if desired.
2.10.2
The predetermined functions of the switches on the 11 position dialer are:
2.10.2.1
Emergency - typically to declare and aircraft emergency.
2.10.2.2
Code - used mostly by EMS operators to declare a patient emergency.
2.10.2.3
Position - mark a position of interest to the pilot or crew.
2.10.2.4
Dialer - 4 event switches are used to dial the programmed numbers.
The MMU does not use any of the event switches so all 8 are available.
2.10.3
Suggested uses for the event switches would be:
2.10.3.1
Connect to an oil pressure switch to automatically send an event report when
oil pressure is lost, to the ground.
2.10.3.2
Connect to a low rotor RPM warning when rotor speed is insufficient, to the
ground.
2.10.3.3
Connect to an over temp/torque light to report this event to the ground.
2.10.3.4
Connect to a relay to let the ground know a circuit breaker has been pulled.
This has been used in the past on lease aircraft to allow the leaser to know
when the pilot has made an attempt to disable the time reporting system,
being the Sky Connect system itself.
Any event the operator would wish to know has occurred in flight, can be recorded
to the ground by the use of a switch closure. The logic can be inverse by the use of a
relay. More than one event can be grouped to one event switch by the use of diodes.
Example: the ground might want to know that an event has occurred that would
require ground maintenance. You might not need to know that a specific event has
occurred immediately, but that something has occurred. Connecting all the engine
events to one input isolated by diodes would report such an event.
Note: Connection of aircraft “required systems” through the tracker (a nonessential
system) will require FAA or other airworthiness approval. Engineering showing
compliance with XX.1309 will have to be completed. Minor or major
change/alteration determination is up to the installer.
