Metar gives METAR and TAF information of more than 2000 airports all over the earth, it also computes the Flight rules near the airports. Airports information can be downloaded from the nelix-dev site :

This application uses the available METAR information to compute the Flight rules :
- VFR : Visual Flight Rules if ceiling is above 3000 feet and visibility better than 8 kilometers.
- mVFR : marginal VFR
- IFR : Instruments Flight Rules
- mIFR : marginal IFR
- no Flight : very bad flight conditions
- no Status : when METAR information is not available.
VFR state is represented on the Flight Rules map by a green pin, a red pin indicates mVFR, IFR, mIFR, and no Flight, a purple pin indicates no available information.
When the network is not available, for example if the Iphone is in plane mode, the information captured is still available. The application keeps last METAR and TAF information on the disk.
The default airports download site can be modified, the user can create its own airports file and use an internet address to made it available to the Metar application.
The airports files must be in ASCII character, one airport per line, each information are separated by one semi colon ";". First field : four capital letters the OACI code, second field the airport name, third is latitude and fourth longitude.
For example :
KLAX;Los angeles international;33.9425;-118.4081;
The airports must be sorted in alphabetic order of the name (second field).
