During every wet season there is a noticeable increase in the number of safety reports submitted

for aircraft;

deviating off route without a clearance; deviating off route by more than the cleared amount; or reporting back on route when they are not.

While the majority of these deviations are due to weather, and considered necessary by the pilot

for safety reasons, they have on occasion contributed to significant occurrences, including

breakdowns of separation.

In the Australian I!s, all airspace above "#$% is &lass A, with separation predicated on aircraft

operating along the defined centre line of their cleared route. Improvements in aircraft navigation

accuracy, increasing traffic levels and the re'uirement to improve operating efficiency has, over

time, led to a reduction in the separation standards re'uired between aircraft in non radar

airspace.

I&A( Doc $$$ ) Air *raffic +anagement re'uires lateral separation to be applied so that the

distance between those portions of the intended routes for which the aircraft are to be laterally

separated is never less than a distance that accounts for navigational inaccuracies plus a specified

buffer in Australia this buffer is -+/. *his means that if an aircraft deviates by more than -+

from its cleared route, allowing for navigation e'uipment and other inaccuracies, the probability

of infringing separation standards between aircraft is increased.

I&A( Doc $$$$ and AI0 Australia provide guidance to pilots in relation to weather deviations in

&ontrolled Airspace, including1

*he re'uirement to obtain a clearance from A*&, 2ow to obtain priority from A*&, and What to do if you cannot obtain a clearance from A*&.

DEVIATION AROUND WEATHER

It is acknowledged that all scenarios cannot be covered in I&A( publications or AI0 and that

under the rules of the air, and in the interests of safety, the pilot may deviate from route as

necessary.

2owever, by re'uesting clearance from A*& prior to commencing or increasing the diversion, the

likelihood of infringing the separation standard with another aircraft is significantly reduced. AI0states that if unable to obtain a clearance and the pilot in command considers the deviation

necessary, a 0A call specifying details of the deviation must be broadcast on the appropriate

fre'uencies.

It should also be noted that, even though your aircraft may be outside of radar surveillance

airspace, if AD345 or AD34& e'uipped, A*& will be aware of your position and your deviation off

route will be observed.

Summary

Deviating off route due to weather is a fre'uent re'uirement, particularly during the wet season,

and is often complicated by a range of factors. 0rocedures have been implemented regarding the

majority of scenarios that may eventuate when deviating, including the pilot6s overall

responsibility for the safety of their aircraft and the right to deviate without A*& clearance if

safety is jeopardised.

2owever, pilots should be aware that due to the reduced tolerances of today6s separation

standards, coupled with the sheer volume of aircraft operating within Australian airspace, to

preserve the safety of the airways system A*& should be contacted for a clearance prior to the

deviation being commenced.

Although volcanoes have the reputation of being very dangerous, (Volcanoes can kill peopleand animals. They can be very destructive.) there nevertheless are advantages of living near

a volcano.

Volcanoes provide resources for energy extraction, also called geothermal resources. Heatfrom the earth's crust is being converted to energy. The big advantages to this type of energy arethat it is very cleanand the resources are nearly inexhaustible.

When a volcano erupts it throws out a lot of ash. At short notice this ash can be very harmful

to the environment, but on the long term the ash layer, which contains many useful minerals, will beconverted to a very fertile soil.

Nearly everywhere volcanoes are located people use the rich soil for farming. Even afteran eruption people still return because of the fertile soil around the volcano.

Volcanoes can produce very spectacular scenery like the beautiful sunsets caused byexplosive eruptions. Other features include plant-rich environments, stunning eruptions, beautiful lavafountains etc.
