2.10.4          Given typical weather briefing, evaluate weather information applicable to a flight, and:
(a)           assess likely changes in weather during the flight (both improving and deteriorating); and
(b)           list phenomena which may adversely affect the flight.
2.10.5          List the conditions that require a pilot to submit a short AIREP.
2.10.6          State the purpose of VOLMET and ATIS broadcasts indicate how this information is obtained and apply this information to practical scenarios.
2.10.7          State what is meant by a Hazard Alert service.

(a)           visibility (good/poor); and
(b)           prevailing winds; and
(c)           typical cloud patterns and precipitation; and
