For <name>, if <name> ends with .fgdata it is treated as the local path of the recording file; otherwise we form the local path by prepending <name> with the tape directory and appending ".fgtape". For <url> (starting with http:// or https://) we download the remote recording (which must be a Continuous recording) in the background to a url-dependent filename while replaying it; if the url-dependent filename already exists it is assumed to be a truncated download and we only download any remaining data. Specify which logging class(es) to use Log to directory DIR. The special value 'desktop' causes logging to the desktop (OS-dependent location).

Please report this to the add-on developers. This aircraft (%VALUE%) contains errors. This may include visual issues, or the aircraft might not fly at all. Check for an updated version of the aircraft from its developers. The selected aircraft (%VALUE%) contains errors. This may cause visual issues, or the aircraft might not fly at all. Please report the information below to the aircraft hangar's maintainers. The custom scenery at '%VALUE%' contains errors. Parts may be missing, or the scenery may not load at all. Check for an updated version of the scenery. Errors were found loading the core simulator files (FGData). This usually indicates a problem with the installation, or your local disk. The joystick (input device) '%VALUE%' couldn't be loaded correctly. This usually means its configuration file is incorrect. Loading a model for another pilot (via multi-player) failed. The other pilot will appear as a default model. (You can disable these errors from the multiplayer settings dialog) Allocating memory failed. Some resources will not be loaded. Adjust your settings to reduce view distance or number of objects loaded. The scenario '%VALUE%' contains errors, and may not work correctly. Problems occurred loading visual effects (shaders). This can cause objects to be invisible or appear incorrect. It can sometimes be fixed by changing rendering settings inside FlightGear, or occasionally, by updating the drivers for your graphics card. Scenery downloaded via TerraSync is not loading correctly. The usually indicates a problem with your network connection or local disk. Problems occured loading simulated aircaft traffic: some traffic may not appear. Errors occurred in an unknown part of FlightGear. Please report this bug to the FlightGear development team.

Border of a high pressure region The border of a low pressure region, in which the airmass is unstable and convective clouds start to form layers and merge into stratiform clouds. Border of a low pressure region If you just got your IFR rating, this is what you are allowed to do. But can you? CAT I minimum This is expert level. You will barely see the taxiway from the cockpit, even if you are on ground. Fog and light drizzle, freezing level at 1000ft. CAT IIIb minimum With just a 1/4 mile visibility and clouds at 100ft, you don't see much of the runway until seconds before touchdown. Trust your instruments to stay alive. CAT II minimum The center of a high pressure region, characterized by descending air and hence only weak cloud development with high visibility. Core high pressure region The core of a low pressure region, characterized by overcast clouds, bad visibility on the ground and significant rainfall. Core low pressure region Fog developed this autumn's morning. Expect good visibility above the layer. However - getting through it can be a challenge. Stay alive for a 500' climb and you'll see the sun! Early morning fog A lovely day for trip to your favorite 100$ hamburger airfield Fair weather A high pressure region, characterized by moderate to strong Cumulus development in the afternoon and fairly good visibility conditions. High pressure region Fetch live weather data for your nearest airport from noaa.gov. You need a working internet connection. Weather is generated automatically, once a valid METAR is received. Live data A low pressure region, characterized by rising air, widespread formation of stratiform clouds and beginning rain. Low pressure region Enter your favorite METAR weather. A valid METAR syntax is required. Manual input After the storm - limited visibility and some showers. Go or No-Go? Marginal VFR You're out for an adventure? Gusty winds blowing from the west and isolated thunderstorms should be avoided. Fasten your seatbelt! Stormy Monday A hot and damp summer day with thunderstorms developing in the afternoon. Be prepared for reduction of visibility in showers and strong gusts near thunderstorms Thunderstorm A warm sector, characterized by high moisture in the air and haze extending up to high altitudes, but otherwise largely convective cloud development.
