This tutorial will take you across how to decode a METAR in Infinite Flight. have a great learning !
WHAT IS METAR ?
METAR is an abbreviation standing for Meteorological Aerodrome Report. It is generally auto generates every 30 minutes. It is used by pilots to check the weather of the airport before takeoff or landing.
AIRPORT NAME, DATE AND TIME -
The highlighted portion starts with a 4 letter ICAO code of the airport you are looking the METAR for. In this case, it is VIDP standing for Delhi. It is followed by date and time the METAR is generated.
VIDP - Delhi airport
311500Z - 31st of the month, 1500 Z is the time
WINDS AND VISIBILITY-
The highlighted portion first consists of the speed and direction of winds. It is followed by the visibility and condition.
13004KT - 130 degrees at 4 knots. The direction of winds are always true headings and not the magnetic
2500 - Visibility of the airport is 2500 meters or 2.5 km
BR - This stands for mist conditions at the airport
The highlighted portion tells about the condition of clouds in the aerodrome. Before decoding it, have a look at the abbreviations used to describe clouds -
Abbreviation for clouds -
NCD - No clouds detected or SKC - Sky clear
FEW - Few clouds
SCT - Scattered clouds
BKN - Broken clouds
OVC - Overcast
SCT030 - scattered clouds at 3000 ft
FEW035 - Few clouds at 3500 ft
BKN - broken clouds at 10000 ft
TEMPERATURE AND PRESSURE
The highlighted portion tells you about the temperature and pressure conditions of the airport.
29/26 - Current temperature / dew point
Q1001 - It is pressure which currently is shows 1001 hectopascals. The Q stands for QNH, which is the Q-code for what pressure you set on the altimeter subscale in order to read elevation above mean sea level. It’s not necessarily the pressure at sea level though - that is QFF (QNH adjusted for temperature deviations from ISA).
NOSIG - This is abbreviation for ‘No Significant Change’. This means that there is no significant change is detected in the weather of airport from quite a long time
