HAZARDOUSWEATHER
RESPONSIBILITY
Cooperative and concerted action is required by pilots,meteorologists and
ATS to ensure themost accurate information is promulgated to assist pilots in
the avoidanceof hazardousweather, particularly thosephenomena associated
with thunderstorms - icing, hail and turbulence.
Meteorologists are responsible for the observationofweather phenomena
and forecasting their occurrence, development andmovement, in terms
applicable to aircraft operations. These forecasts need to beproduced in
sufficient time for avoiding action to be taken.
ATS is responsible for distributing reports of hazardousmeteorological
conditions topilots as a part of the Flight InformationService. ATS also
makes visual and limited radarweather observations for the informationof
meteorologists and pilots, and is responsible for relayingpilotweather reports
to theBoM. At some locations, ATS is providedwithMETRAD or RAPIC
whichmay supplementweather adviceby theATS. Details aregiven inAIP
GEN 3.3.
Whilstmanoeuvring inhazardousweather situations, pilots are responsible for
the safety of their own aircraft using advices and clearances passedbyATS
and informationobtained from their own visual or airborne radar observations.
They are also responsible for passing visual and airborne radar observations of
hazardousweather toATS.
PILOTACTION
Outside controlled airspace all hazardousweather avoidance action is the
sole responsibility of the pilot in command. However, inorder to preserve the
safety of the aircraft and other air traffic, thepilot in command is requested to
adviseATS of intended actions.
Thepilot in command, both inside and outside controlled airspace,must
adviseATS promptly of any hazardousweather encountered, or observed
either visually or by radar.Whenever practicable, those observations should
include asmuch detail as possible, including location and severity. Hazardous
weather includes, in particular, thunderstorms, severe turbulence, hail, icing
and line squalls, and volcanic ash cloud.
