Apollo II Morrow GX60 GPS readout/COM radio Ver 1.2

New with this version:
Now the MSA display shows correctly the value for Minimum Safe Altitude.
Also there is a better working for the power on selftest when power of the GPS
is on and the avionic main switch in the panel is off.

Description:
This gauge is a readout for the FS2002 GPS combined with the COM functions. It
displays the current GPS NAV data from the FS GPS and provides 14 display pages
with GPS CDI needle, minimum safe altitude, altitude hold feature, altimeter
setting, end altitude computing, flighttime, time in UTC and a
countdown timer. Also messages will be displayed for the countdown timer and GPS
functions. As the original this gauge has some "smart buttons".

The data displayed are based on some of the Apollo GX60 NAV pages. It does not
simulate a GPS with database and menu.

This gauge provides the data needed to navigate and fly using the values of the
MSFS GPS in a realistic display. You have to use the FS built-in GPS for
changing GPS modes.


The display, buttons and knobs:
See the picture ExplGX60.bmp which gives an overview of the display pages and
functions.

The display contains 14 pages with the GPS readouts, a CDI to intercept the
desired track to next waypoint, a flighttime/time page, a countdown timer and
more. In the lower part of the display the COM frequencies are allways visible.
Left hand showing the frequency in use marked with "a" and right hand the
standby frequency marked with "s".

The small knob on the upper right side turns the GX60 on and off. If the
instrument is turned on you will first see test screens for a few seconds.
You can have the power switch always set on and use a central avionic circuit
switch in your main panel to set the power of ALL radios in this package.

The buttons below the display are "soft coded" buttons.

The MSG button let you read the timer and GPS messages. If a message is
generated by the gauge an indicator is blinking above the MSG button.
Pressing the MSG button shows the belonging message. Pressing MSG again removes
the message from the screen.

The INT button is one of the smart buttons. It indicates "SKP" while the power
on selftest is in progress. Pushing the SKP button while the selftest is running,
will skip the test.

The COM button is the second of the smart buttons. It sets the radio to COM mode.
While in COM mode the button symbol "<-->" is shown. Pressing the button now
swaps between COM in use and COM standby frequency. Only the standby frequency
can be changed. Press NAV to leave the COM mode.

The buttons on the right side of the display are "hard coded" buttons.

The NAV button sets the radio to the so called NAV mode, this means that the GPS
functions are active and not that the GX60 provides NAV frequencies in addition.
Only in NAV mode the various display pages are selectable.

The D-> button toggles the FS GPS window on and off if GPS window is window02 in
the panel.cfg file.

The INFO button opens/closes the FS ATC window.

The SEL button works in the UTC time page, the Altimeter Setting page, the End
Altitude page, the Altitude Hold page and in the Countdown Timer page. Pressing
SEL starts a blinking cursor for the digits and you can change the values.

The ENT button let you finish the entries of the selected/changed values.

The selector knob at the lower right side of the radio has two parts: a large
knob and a small knob. Depending on the current mode and page the knobs have
different functions:
- while in COM mode the large knob increases/decreases the whole digits and the
  small knob increases/decreases the fractal digits of the COM standby
  frequency.

- while in NAV mode the large knob selects the displays for NAV, Altitude Assist,
  GPS position and the timer page. The small knob selects the various available
  pages for each kind of display.

- while in NAV mode on the previous described pages in context with the SEL
  button, and SEL is pressed, the large knob changes the cursor position and the
  small knob changes the values of the digits.

How to use the course deviation indicator (CDI):
Press NAV and click left/right on the small knob to select a page where the CDI
is shown in the upper part of the display. Watch the CDI while flying. The
little triangle as a symbol for your aircraft points always head up TO the next
waypoint. The course deviation is indicated by little arrows and they stand for
the left/right XTrack. If XTrack is less than +/- 0.05 nm, the arrow points
straight ahead. To intercept the desired track "follow the arrows". On the
left or right side of the CDI screen the XTrack in nautical miles is displayed.

How the flighttime timer works:
The built-in flighttime timer starts automatically when power is on and the
selfstest is finished.

How to set the UTC clock:
Press NAV and click left/right on the small knob to select the time UTC page in
the NAV display. Press SEL to activate the cursor on the hours position. Click
the small knob left/right to decrement/increment the hours. Click the large knob
to set the cursor over the minutes position. Click the small knob left/right to
decrement/increment the minutes. Press ENT to accept the new adjustment.

How the minimum safe altitude works:
In the original instrument there is a database which containes informations
about heights of terrain and obstacles. Because this gauge has no access to
such informations when flying over the FS scenery, we use a little trick to
simulate the minimum safe altitude. FS returnes an internal "radar height"
value meassured from aircraft to ground. This current value plus an addition of
2000 ft gives the minimum safe altitude rounded to the next 100 ft. If you are
proceeding in more or less "flat" terrain an addition of 1000 ft may be
sufficient.

How to set the local altimeter:
Press NAV and click left/right on the large knob to select the Altitude Assist
display and page. Press SEL to activate the cursor for the barometric pressure.
Click the small knob left/right to decrement/increment the value in steps of
0.3 mb. Press ENT to accept the new adjustment.

How to compute end of climb or point of descend:
Press NAV and click left/right on the small knob to select the End Alt page. The
default value is set to minimum safe altitude.
Press SEL to activate the cursor for the End Altitude. Click the small knob
left/right to decrement/increment the value in steps of 100 ft.
Press ENT to accept the new adjustment. While flying to the next waypoint the
GX60 computes the estimated distance from the waypoint when you reach the
desired end altitude. This is depending on current waypoint distance, current
vertical speed and current ground speed.

How to use the altitude hold feature:
Press NAV and click left/right on the large knob to select the Altitude Assist
display. Click the small knob to select the Altitude Hold page. The default
value is set to the current pressure altitude.Press SEL to activate the cursor
for the altitude to hold. Click the small knob left/right to decrement/increment
the value in steps of 100 ft. Press ENT to accept the new adjustment.
The altitude hold feature has a buffer of 300 ft. If this buffer exceeds, a
message will be indicated above the MSG button. You can watch the difference
between altitude hold an current altitude by selecting the page Baro Alt in the
NAV display.

How to use the countdown timer:
The built-in countdown timer can count down from 99:59:59 to 00:00:00. To adjust
the timer press NAV and click left/right on the large knob to select the
countdown timer page. Press SEL to activate the cursor. The default value of 3
minutes is set automatically. Click the small knob left/right to decrement/
increment the minutes. Click the large knob to set the cursor over the hours or
seconds position. Click the small knob left/right to decrement/increment the
digits. Press ENT to accept the timer adjustment. If the timer has count down to
00:00:00 the message indicator is blinking. Press MSG to read the message
"Countdown Timer Expired".
