M1 Discuss the types of adverse weather that may affect
aviation operations in the UK.
The weather forecast is a key element of the pilot's pre-flight checks
and flight crew will continually update their weather information
throughout a flight. It is possible to prevent the adverse effects of
weather on the industry if airlines and the industry as a whole work
together to help clarify this natural phenomenon. Some of the causes
that result to accidents include turbulence, low ceiling and reduced
visibility, thunderstorms, snowstorms and ice, blustery weather,
thunderstorms, icy and wet runways can lead to crash landings.
Various airlines have gathered weather reports and are constantly
updating them on the changes in weather patterns. Fog, snow, ice, and
crosswinds mean that air traffic controllers need to widen the distance
between aircraft arriving, restricting the number of aircraft that an
airport can accommodate. The same conditions can make it slower and
more difficult for aircraft to taxi between the runway and the terminal
building. Reduced visibility can dramatically reduce an airport's
potential, resulting in airborne or ground delays resulting in diversions,
cancellations, missed connections and additional operating costs. The
five key aspects that climate change is anticipated to affect aviation
are increases in temperature, precipitation, storm patterns, sea level
and wind patterns. The change in temperature affects aircraft
performance, infrastructure, and patterns of demand. Delays and
cancellations can be increased by changed precipitation patterns. More
intense storms are predicted, with increased disruption of the
schedule. Increasing sea levels could decrease airport capacity and
cause disruption of the network. Changing wind patterns may increase
turbulence, impact travel times and cause disruption.

Heavy snow- As snow can be unpredictable sometimes, and
cleaning off the runways and planes take time, you may have to
wait several hours to days before you can get a flight out on any
airline. To predict snow, many forecasting techniques and models
are used. Although overall accuracy in predicting snow conditions
has improved over the years, accurate forecasting of snow levels
can still be a challenge. On METARs and TAFs, snow is indicated
by the descriptor "SN." On the ground, as well as during landing
and take-off, snow and blowing snow can greatly affect the
aircraft. When visibility is significantly reduced, aircraft
acceptance rates are also reduced as a consequence of snow
activity. This generates operational delays, and aircraft can often
need to be diverted to alternative airfields. Airport operations can
be impacted by heavy snow accumulation, and runways can be
closed for plowing. If the rate of snowfall is such that runways
cannot be held clear by plowing and treatment, a specific airfield
can be forced to close. Snow and slush freezing on the aircraft
brakes is a problem for operators landing at airports experiencing
snow events, so it is advised to avoid disembarking through loose
snow, slush, or puddles that may stick to the brakes and freeze.
Snow can strongly impact visibility and has the ability to instantly
decrease visibility. This is particularly true in circumstances in
which the snowfall rate is rising. When snow is blown around by
powerful winds already on the ground, this also contributes to a
drastic decrease in visibility. Operators should give serious
attention to the possibility for major snow events during the trip
planning phases. With the development of today's more reliable
long-range global weather models, 7-10 days before service,
snow events are now accurately predicted. While generally
predictable, major snow events have the potential to evolve
rapidly. It is necessary for flight crews to be aware of how
visibility can be affected by these atmospheric phenomena. In
certain situations, diverting to an alternative airfield or deciding
to work on separate days to prevent a snow event is the safest
course of action.
