Allow for multiple frequency for Controll airspace #250

Open www2000 opened 6 years ago

www2000 commented 6 years ago

Hi i wand to report that there is is a problem that little navmap support only one frequency for Controll airspace, where for example Amsterdam CTR have 5 frequency for INF, 5 frequency for ACC, 1 frequency for VOL, 2 for MIL ACC, 1 for MIL INF and 5 for UAC. Where are 10 on the VHF frequency and 9 on UHF frequency. There are areas there are using frequency on the VF band.

My propose is that a new table be create call boundary_freq that have the foaling information: ID boundary_id name com_type freq freq_band mil Mandatory com_name min/max_altitude_type *min/max_altitude

*: i don't know the this is required information for use in this table the values for freq_band are H for the HF band (3000 kHz - 30,000 kHz)( this the encoding for 123.456MHz) V for the VHF band (30,000 kHz - 200 MHz) U for the UHF band (200 MHz - 3000 MHz) C For 8.33KHz communication channels

The values for freq are: HF band 12345 (12345 kHz) VHF 123456 (123.456MHz) UHF 123456 (1234.56MHz)

This can be backward compatible with older version of little navmap if nothing change in the "boundary" table. edit : add the mil and mandatory column

Thank you for the proposal. I'm already selecting a single frequency from the Navigraph data which is only a workaround so far. Compatibility is important. LNM usually checks if columns or tables exist or not if the schema is older. Alex

I have edit my early post to add a entry for 8.33 KHz communication channels

Removed from 2.4. This is too much work for such a small feature. If affects all database compiler including Navigraph and you cannot use the real world frequencies in the simulator anyway.

www2000 commented 5 years ago

No problem with postpone so long that this is on the roadmap. Where can i read the code for the database compiler and if its public the Navigraph compiler?

albar965 commented 5 years ago

Compiler code for all platforms (FSX, P3D, X-Plane and Navigraph) is in the atools library. The top level class used to compile is the navdatabase.h. You could think of it as a facade (pattern) to the rest. Database schema documentation is in the create_*.sql scripts in the resources folder. The Navdatareader is a command line tool that can be used to create scenery databases without LNM. Alex

He any updates on this issue?

No.
