What is an F215?
Low level aviation area forecasts (commonly known as a F215) are area weather forecasts provided specifically for UK general low level aviation.
What area does a TAF cover?
A TAF is a report valid for 5 statute mile radius around an airport. A TAF’s terminal area then extends out an additional 5 statute miles, so 10 statute miles total.
How long is METAR valid for?
an hour
The METAR only gives you a small snapshot in time. They are only good for an hour. They are usually refreshed around 55 past the hour. TAFs, on the other hand, cover a 24 to 30 hour period and they are published 6 times a day (0000, 0600, 1200, 1800).
What range does a METAR cover?
A metar report is good within 5 NM of the station. “VC” or vicinity of the airport is defined as between 5-10NM from the station. “DSNT” or Distant is used beyond 10NM from the station.
How long do METARs last?
The METAR only gives you a small snapshot in time. They are only good for an hour. They are usually refreshed around 55 past the hour. TAFs, on the other hand, cover a 24 to 30 hour period and they are published 6 times a day (0000, 0600, 1200, 1800).
How do you decode a Metar?
Decoding a METAR
- PHNL = the airfield, Honolulu’s Daniel K.
- 250953Z = the date and time of the report.
- 05007G17KT = the wind conditions.
- 10SM = visibility.
- FEW024 / FEW040 = cloud cover.
- 27/19 = the temperature and dewpoint.
- A3001 = the atmospheric pressure, a.k.a. altimeter setting.
What does VP mean in weather?
Visibility
| Value | Description |
|---|---|
| VP | Very poor – Less than 1 km |
| PO | Poor – Between 1-4 km |
| MO | Moderate – Between 4-10 km |
| GO | Good – Between 10-20 km |
What are TAFs and METARs?
They provide a concise description of the wind, visibility, cloud and weather conditions over periods ranging up to 30 hours ahead. TAF are routinely provided for over 50 UK airports. Like METARs they are provided in a coded format to ensure their content is broadly consistent with TAFs issued anywhere in the world.
What are METARS and who can use them?
They are primarily issued for aviation personnel (Pilots, Air Traffic Controllers, Airport Authorities, etc.) but can be used by anybody who knows how to decode them. A METAR is a coded text report of the current weather conditions observed at an airport, and is issued every 30 minutes in Ireland.
How much data is in a METAR?
The information from one round (cycle) of all approximately 4,200 measuring stations together is still about 3 Mb. Yet encrypted METAR and TAFs do have their limitations.Sometimes it is difficult to quickly visualize all the information it contains.
How do I find the METAR of a specific airfield?
Use the search function to find the METAR, TAF and NOTAM of a specific airfield. You can search by the name of the field or the ICAO code. Click to center on your current position. For this it’s of course necessary to share your location with us. Click again on to open the METAR of the nearest airport.
