Safety recommendation SL No. 2013/05T

At one time, between two METARs, visibility dropped from more than 10 km to 2 000 metres without this being reflected in published observations. When METARs are issued every half hour, there is no requirement for a SPECI to be issued even in the event of significantly reduced visibility. Delays in communicating information are unfortunate in a country such as Norway, where the weather changes rapidly due to the topographical conditions.

The Accident Investigation Board Norway recommends that the Norwegian Civil Aviation Authority considers whether the aviation weather service provisions should be amended to include requirements for faster announcement of significant weather changes.

Safety recommendation No. 2012/01T

If the rescue parachute is deployed during the flight, the aircraft is in a serious emergency. The probability of the emergency and position being noticed by the alarm and rescue services increases if the emergency locator transmitter (ELT) is triggered automatically at the same time. 

The AIBN recommends that Cirrus Aircraft develops an automatic system that ensures that the ELT is triggered when the Cirrus Aircraft Parachute System (CAPS) is engaged.
