Metar application 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 :
- http://www.nelix-dev.com/airport/xx.txt,
xx stand for the country tag :
alaska.txt = the US Alaska state
as.txt = Austria and Swizerland
au.txt = Australia
bnl.txt = Benelux (Belgium, Netherlands, Luxemburg)
cae.txt = the east of Canada
caw.txt = the west of Canada
es.txt = Spain
fr.txt = France
gd.txt = Germany, Denmark
....
uk.txt = United Kingdom and Ireland
use.txt = the east coast of USA
usce.txt = the center east of USA
uscw.txt = the center west of USA
usw.txt = the west of USA
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
- I IFR : Intensive IFR
- VI IFR : Very Intensive 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 internal memory.
