Aircraft
ADF provides you with a GPS based aircraft radio magnetic indicator
(RMI) instrument shown as a typical Bendix/King KI-227 instrument.
It lets you 'tune' aircraft navigation non-directional beacons (NDB) and gives you bearing and distance information to that NDB.
It uses a worldwide navigation database (downloaded on first use) and is not restricted by radio range.
It uses your device GPS position and heading to calculate bearing and distance to the tuned NDB.
Features:
- Bendix/King KI-227 face
- Worldwide NDB navigation database (downloaded on firt use)
- Digital Bearing and distance to station indications
- Option to operate as rotable compass card (just rotate with your finger!)
- Filtered and smoothed display - no jitter or jumping!
- Support for portrait and landscape screens
- Support for multiple screen resolutions
Usage
IMPORTANT
POINT 1 - Please ensure you have an active data connection when
starting the app for the first time as it will attempt to download the
radio navigation database.
IMPORTANT POINT 2- To function
correctly, the application requires not only a GPS position fix but also
a valid GPS groundtrack. It may be necessary to move your device to
give the GPS the data it requires to make this calculation.
Don't use it until you know its working!
Until
a GPS fix is obtained, or in case of GPS fix being lost, the ADF will
'park' itself at 90 degrees and '---' will be shown in both the bearing
and distance text boxes.
Tuning a station
Use the app menu to
select 'Tune NDB'. You will be presented with all the NDB stations
within 200 nautical miles of your current location. Selecting a NDB will
tune it up. Hit your devices 'Back' button when you have selected your
desired VOR.
Interpreting the display
If you have a valid GPS
fix, the bearing to the NDB will be shown by the ADF needle and the top
(or left in landscape mode) digital text box will show a digital bearing
indication - the course you need to fly to travel towards the beacon.
The distance in nautical miles to the NDB will be shown in the bottom
(or right in landscape mode) digital text box.
Rotatable compass card
By
default, the ADF compass card will slave itself to the GPS groundtrack,
making the instrument a true single-needle Radio Magnetic
Indicator(RMI). However, you can manually turn the ADF into a rotatable
compass card instrument using the toggle option in the app menu. Once
toggled, you can easily rotate the card using your finger.
