KLN 90B GPS Readout

(turn on word wrap)
This gauge is a readout for the FS2000/FS2002 GPS. It displays the
current navigation data from the built-in FS2000 GPS and provides GPS map display switching
and GPS/NAV switching. The data formats displayed are based on the ones provided by the
Bendix/King KLN 90B GPS.

This gauge does not simulate a GPS, it only provides display and switching functions.

This gauge displays the data needed to navigate and fly using the
built-in MSFS GPS in a realistic display without having to use the
built-in GPS display except when changing GPS modes.

The D-> button toggles the GPS display on and off and the ENT button
replaces the GPS/NAV switch normally used when using the GPS to
drive the autopilot. When the GPS is the autopilotNAV source "GPS" is
indicated in the lower right corner of the display.

The display contains four lines of data with the upper right line
displaying two XTK modes and an expanded CDI scale when in the CDI mode.

LINE DESCRIPTION EXAMPLE
Line 1L scale factor and left half of expanded CDI
Line 2L Bearing to Waypoint -- BRG 025 (degrees)
Line 3L Ground Speed -- GS 129 KT (knots)
Line 4L Waypoint ID -- -> RQZ (next waypoint)

Line 1R XTK information displayed in one of three modes.

Mode Information Displayed
CDI -- right half of expanded CDI
two scale factors +/- 5 NM and +/- 1 NM
XTK -- XTK -1.7 NM
distance off track in NM (- means track is to left of aircraft)
FLY TO -- FLY L 1.2 NM ( L = left / R = right )

Line 2R Distance to Waypoint -- DIS 13.1 NM (nautical miles)
Line 3R Estimated Time to Wpt -- ETE 00:06:02(hh:mm:ss)
Line 4C Desired Track to Wpt -- DTK 032 (degrees)
Line 4R Autopilot NAV source -- GPS or NAV

CDI MODE SYMBOLOGY

| -- desired track
^ -- aircraft track if not same as desired track
+ -- each mark is 1 NM or 0.2 NM

CONTROLS

In this version there are four active controls.

D-> button -- toggles GPS display on and off

ENT button -- toggles autopilot NAV source between GPS and NAV1

CDI/XTK/FLY knob -- selects XTK display modes

right CRSR button -- toggles CDI mode senstivity between 0.2 NM per mark and 1.0 NM per mark

ASSUMPTIONS :

GPS window is defined for panel that gauge will be used with.

In panel.cfg the gps window uses the standard "ident" of
ident=GPS_PANEL.

The user knows how to install gauges in a panel.

NOTE : Since the actual control is performed by the built-in GPS, this
gauge may be installed on a secondary window and the window may be
closed except when checking the readings, although for realism it
will be better to have this gauge installed on the main panel.

INSTALLATION :

The master gauge is named cad_kln90bro and it contains two gauges. The gps readout gauge (gpsro), and a small gauge which is an addon
for the Bendix/King KAP140 autopilot which implements the
up/down buttons for additional realism (apupdn).

The GPS gauge is addressed in panel.cfg as cad_kln90bro!gpsro and
the updown addon as cad_kln90bro!apupdn.

It is not necessary to use the updown addon, I just included
it since FS2000 gauges are multiple gauges by design and I
like having the updown buttons on the KAP140 autopilot.


NAVIGATIONAL TERMS from Bendix/King KLN 90B manual

BRG - Bearing to waypoint (degrees)
DIS - Distance to waypoint (nm)
DTK - Desired Track (degrees)
GS - Groundspeed (nm/hr)
TK - Actual Track (degrees)
WPT - Waypoint
XTK - Cross Track Error Correction (nm) displayed as
"FLY L 2.3 nm" or "XTK -2.3 NM"
ETE - Estimated Time Enroute (hrs:min)
CDI - Coarse Deviation Indicator

NOTES :

This is version 1.3 of this gauge and I will release
an update if any more updates are required. Please send me an email
if anything doesn't work as expected or if there are any questions.
I am always open for suggestions if you have any ideas on
improvements that can be made.

This gauge is a completely new work, although it is based upon
ideas I got from the GPS integration method used by FSD International
in their Commander 115 and information provided by Dai, Arne Bartels,
and all the others which are so helpful at the FlightSim Panel
Design Forum and the AvSim MSFS Aircraft and Panel Design Forum.
No part of any other person's gauges is included in these gauges.
