Cessna 421C – MOCCA


The Met Office Civil Contingency Aircraft (MOCCA) is a Cessna 421C aircraft by DO Systems & Cranfield Aerospace for use by the Met Office & Civil Aviation Authority. The aircraft is designed to monitor and measure gases and aerosols in the atmosphere, such as pollutants like volcanic ash, dust and smoke. The aircraft will be used to monitor ash during any future volcanic ash incidents. It will also be scrambled to operate in a range of situations where expert sampling of air pollutants may be required, such as large fires, ensuring the safety of those in the air and on the ground. The aircraft will be on static display at the Air Show, alongside an exhibition from the Met Office.
