Apollo SL30 NAV/COM radio Ver 1.0

UPS Aviation Technologies description:
Combining powerful 760 channel VHF communications with 200 channel VOR,
Glideslope and Localizer receivers, the SL30 provides a fullfunctioned
navigation and communications solution in a small footprint at a very affordable
price. Besides traditional Nav/Comm features, the SL30 also incorporates
workload-reducing functions such as automatic decoding of the Morse code station
identifier for VOR/LOC/ILS, most-used frequency storage in unit memory,
built-in course deviation indicator and more.

The SL30, the smallest Nav/Comm on the market, is loaded with features and
functionality. The only Nav/Comm with the ability to monitor the standby comm
frequency, the SL30 VHF receiver operates from 108MHz to 117.95 MHz—decoding
both the VHF Omni Range and Localizer navigation signals. The built in
Glideslope receiver will automatically tune the corresponding glideslope paired
frequencies (328 MHz to 335 MHz) when the localizer is tuned. The SL30 includes
the powerful yet efficient 8 watt comm transmitter used in the other Apollo
Slimline and GX avionics.

Description:
This gauge is a combined NAV/COM radio. It provides the traditionell FS NAV and
COM features as well as built-in course deviation indicator, OBS mode, preselect
emergency frequency and more.

This gauge has functional buttons like the real instrument.

The Buttons and Knobs:
See the picture ExplSL30.bmp which gives an overview of the functions.

The power knob switches the radio on and off.
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 <--> button swaps COM and NAV frequencies from standby to frequency in use.

The COM button sets the radio to COM mode. The display shows on the left side
the COM frequency in use an the COM standby frequency indicated with a "s".
In COM mode the NAV data are also displayed on the right side.

The NAV button sets the radio to NAV mode. The display shows on the left side
the NAV frequency in use an the NAV standby frequency indicated with a "s". On
the right side NAV data indicated as "vor", the TO/FROM indicator and the
bearing to, respective the radial from the station are visible. If the frequency
in use is an ILS localizer, the display shows "loc" and no other data. If the
NAV signal is low you see "- - -" at the place of the bearing/radial value.

The SYS button opens/closes the FS ATC window.

The OBS button sets the radio to OBS mode. While in OBS mode the SL30 turns the
OBS knob of the VOR instrument, the OBS value is displayed and the CDI is
showing the current deviation left or right. If the current NAV frequency is an
ILS localizer, the display shows "loc" and OBS mode is locked.

The T/F button toggles the TO/FROM indicators. TO indicates the bearing to the
station and FROM indicates the current radial from the station.

The ID button toggles the sound of the Morse ident code on and off. This button
interacts with the Apollo audio selector panels SL10-MS and SL15.

The SEL button has two tasks:
- while in COM mode you can quick select the stored emergency frequency 121.50.
- while in NAV mode you can select the display for the DME data.

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

The volume knob on the left side of the radio turns power on or off.
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 selector knob at the right side of the radio has two parts: a large knob
and a small knob. Depending on the current mode 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 increases/decreases the whole digits and the
  small knob increases/decreases the fractal digits of the NAV standby frequency.

- while in OBS mode the large knob increases/decreases the OBS in ten degree
  steps and the small knob increases/decreases the OBS in 1 degree steps.
  
- while SEL is pressed the large knob let you select one of the stored values.
  To interrupt any selection press COM or NAV.

How to get the stored emergency frequency:
Press COM to set the radio in COM mode. Press SEL to reach the selection menu.
The display now shows "select COM?". Click the large knob to show the stored
channel. "emergncy 121.50" will then be dislayed. Press the <--> button to make
the emergency frequency the frequency in use.

How to get the DME data:
Press NAV to set the radio in NAV mode. Press SEL to reach the selection menu.
The display now shows "select NAV?". Click the large knob to show the stored
menu entry. "show dme data?" will then be dislayed. Press the ENT button to
select the DME diplay. If the current NAV channel is providing DME information,
on the right side of the display these values are now showing up. If no DME data
is available, the display is blank.
Repeat this procedure to remove the DME data display.

How to use the course deviation indicator (CDI):
Press NAV and select a VOR frequency. Press OBS to set the radio in OBS mode.
Click the large and/or small knob to dial the desired VOR radial. Watch the CDI
on the right side of the display. The little aircraft indicates the TO/FROM flag.
If you proceed TO the station, the aircraft points ahead, if you proceed FROM
the station, the aircraft points back. The course deviation is indicated by
little bars on the right or left side of the little aircraft. Each bar
represents a value of 2.5 degress. To intercept the desired radial "fly into the
 bars".
This feature is avaible only for VOR stations and not so for ILS localizers. If
the NAV signal strength is low, "flagged" will be displayed instead of the CDI.


Notes:
This is version 1.0 of this gauge and if any updates are required I will release
them. Send me an email if anything doesn't work as expected.

This gauge is programmed completely new with EASYGauge, a wonderful easy to use
