|
|
# From Dave Perry:
|
||
|
|
# Patch goals:
|
||
|
|
# 1. Implement instrument and pannel lights controled by the nav-light switch.
|
||
|
|
# 2. Use Instruments-3d/vor which includes GS flag and filters for smooth movement of cdi and gs needles to and from parked position.
|
||
|
|
# 3. Adjust model and pilot view per the agreed to changes in Re: [Flightgear-devel] c172p pitch at cruise question, 12/06/2008 02:27 PM. These changes were never committed.

# Dave PERRY:
|
||
|
|
#
|
||
|
|
# "This patch adds instrument lights to the radio stack and a repaint of
|
||
|
|
# the fuselage and tail to look better with osg."

# Revision 1.1 2008/11/03 16:18:06 torsten
|
||
|
|
# added ki266 3d-instrument, see ki266.xml for help
|
||
|
|
#
|
||
|
|
#
|
||
|
|
# Basically, we check the "time to station", "distance to station" and "speed"
|
||
|
|
# properties and generate the values to show on the displays, based on the switch-
|
||
|
|
# setting.
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# just create one instance of ki266 class for each dme you have in your aircraft
|
||
|
|
# like this:
|
||
|
|
# ki266.new(0);
