EMS Operation

5-12 SkyView Pilot’s User Guide - Revision Q

The column to the left of the circuit name is blank when the circuit is turned off, displays a

green checkmark when it is turned on, and displays a red “X” when there is a fault condition.

The column to the right of the circuit depicts contextual information about the circuit.

Nominally, this is the current draw - in Amps - for circuits that are powered on.

If the circuit is in a fault condition, the fault condition is described. Possible fault conditions for

circuits include:

 OVERV: Over Voltage Limit (alternator only)

 SHORT: Shot Circuit

 OVERC: Over Current

 OPEN: Open Circuit

Additional information that is only displayed for flaps/trim includes:

 RUNWY: Runaway trim or flaps

 ACTVE: Actively moving trim or flaps

 DSABL: Trim or flaps disabled

Circuit Control

Whenever the VP-X page is being displayed, the joystick underneath that page lets you highlight

and select each circuit. Simply rotate or move the joystick up and down to select a circuit. If a

fault exists, the first faulted circuit will be automatically highlighted.

When a circuit is selected the menu at the bottom of the SkyView screen automatically changes

to allow control of the circuit.

All Circuits

 RESET button: Press this button to reset any circuit that has a fault condition that the

VP-X will allow to be reset. This button will be grayed out and unavailable if the circuit is

not in a fault condition.

Flaps and Trim Circuit Controls

 UP and DOWN buttons:

o For Elevator Trim: Moves the elevator trim up or down as described in the VP-X

documentation. This button can be held down for continuous trim movement.

o For Flaps: Moves flaps up or down as described in the VP-X documentation.

Depending on the VP-X configuration, a single quick press of the UP or DOWN

button may move the flaps to a preconfigured angle or notch of flaps. Or, it may

only move the flaps momentarily. This button can be held down for continuous

trim movement.

 LEFT and RIGHT buttons:

o For Roll Trim: Moves the roll trim left or right as described in the VP-X

documentation. This button can be held down for continuous trim movement.
