KAP315 ANNUNCIATOR PANEL

1: Autopilot Mode Annunciators

The KAP315 Annunciator Panel provides the pilot with continuous information

on system operating status. It shows modes in operation, as well as modes „ar-

med” prior to capture. Clicking on the annunciator panel opens a zoomed auto-

pilot window.

Additional KFC300 Autopilot Operation Modes

IAS Hold mode (IAS)

The IAS HOLD mode is selected by depressing the IAS button (7) on the KMC 340

Mode Controller. „IAS HOLD“ will be lighted on the KAP 315 Mode Annunciator

Panel and the pitch command bars will be activated on the FCI to call pitch ma-

neuvers necessary to maintain a constant indicated airspeed. The reference air-

speed will be the indicated airspeed at the time of IAS HOLD engagement, and is

independent of power setting.

If the autopilot is engaged, airspeed will be automatically maintained, while ver-

tical speed is adjusted, and loss or gain of altitude will depend on power set-

ting.

The reference airspeed may be adjusted at a rate of two knots per second by use

of the Vertical Trim Knob on the KMC 340 Mode Controller.
