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 NAV source "GPS" is 
indicated in the lower right corner of the display.

The display contains eight lines of data with the upper right line
displaying three XTK modes and two CDI scales when in the CDI mode.

LINE        DESCRIPTION             EXAMPLE
Line 1L     Waypoint ID         --  -> RQZ      (next waypoint)
Line 2L     Bearing to Waypoint --  BRG 025     (degrees)
Line 3L     Ground Speed        --  GS 129 KT   (knots)
Line 4L     Track               --  TK 004      (degrees)

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

    Mode    Information Displayed 
    CDI --  same information format as HSI
            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 data      --  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 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 standard ident of ident=GPS_PANEL.

The user know 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 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 kln90bro!gpsro and the updown addon as 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

TK      - Actual Track (degrees)
WPT     - Waypoint
XTK     - Cross Track Error Correction (nm) displayed as

NOTES :

This is the first version of this gauge and I will release an update if any updates are required.  Please send me an email if anything doesn't work as expected or if there is 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.
