Windshear warning messages are given in the arrival and departure ATIS broadcasts in one of
the three formats:
- “Windshear Forecast” (WSF) - when the meteorological conditions indicate that low level windshear on the approach or climb-out (below 2000ft) may be encountered.
- “Windshear Forecast and Reported” (WSRF) - as above, supported by a report from at least one aircraft of windshear on the approach or climb-out within the last hour.
- “Windshear Reported” (WSR) - when an aircraft has reported on the approach or climb-out within the last hour, but insufficient meteorological evidence exists for the issue of a forecast of wind shear. 不足的
Vertical visibility is not measured in the UK. In the UK when the sky is obscured “VV///” is reported in lieu of cloud information.
