Aircraft VOR Free
***
HEREEE!!!!
An aircraft navigation VOR receiver for you mobile device!
Aircraft VOR provides you with a GPS based aircraft VOR instrument shown as a typical Bendix/King KI-208A instrument.
It
lets you 'tune' aircraft navigation Very High Frequency Omni-direction
range (VOR) beacons via a worldwide database and allows you to select
and track a VOR radial to or from the VOR station.
It also optionally shows you your cross-track deviation in metres.
Features:
- Bendix/King KI-208A face
- Worldwide VOR navigation database (downloaded on first use)
- Digital CRS and distance to station indications
- Option to display cross-track error
- Filtered and smoothed display - no jitter or jumping!
- Support for portrait and landscape screens
- Support for multiple screen resolutions
This
is the free version of the app. It is supported by ads and has a five
minute time limit. Upgrading to the paid version removes both of these
restrictions.
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.
Don't use it until you know its working!
Until
a GPS fix is obtained, or in case of GPS fix being lost, the VOR on/off
indicator will be shown and the distance to station will show ----
Tuning a station
Use
the app menu to select 'Tune NAV'. You will be presented with all the
VOR stations within 200 nautical miles of your current location.
Selecting a VOR will tune it up. Hit your devices 'Back' button when you
have selected your desired VOR.
Finding out which radial you currently on
The
first thing to remember when trying to find out which radial you are on
is that all radials are from the station. The indicator is able to show
you which direction to track to the station but this is not directly
which radial you are on (it's 180 degrees out). To centre the needle and
find the radial you are currently on, rotate the instruments compass
card until
the needle centres with a FROM indication.
Finding out your current bearing to the station
Sometimes
it is necessary to obtain your current bearing to station. To obtain
the bearing from your current position to the station, rotate the
instruments compass card until the needle is centred and the TO flag is
showing.
Flying a specific radial
Sometimes it is necessary
to fly along a specific radial to/from the station. In this case, first
select the radial you wish to fly by rotating the instruments compass
card to that radial, ensuring the TO/FROM flag is in the correct sense.
The VOR needle will then indicate to you which direction you need to
move in order to intercept your desired radial. If the needle is to the
right, fly right. If it is to the left, fly left. Upon approaching your
desired radial, the needle will close into the centre. Each dot
indicated on the display is 2 degrees, so the needle will start to move
when you are within 10 degrees of the desired radial. You should begin
to turn onto a desired course, which matches your radial so that your
aircraft heading matches the desired radial when the needle is centred.
You will need to compensate for wind appropriately.
Displaying X-Track deviation
You
can display you current cross-track error in metres by toggling the
menu option. This will show you the number of metres left or right of
track when you close to less than 1km of your desired radial
