Spray Missions & Flights in Known Icing (FIKI)

Aerial Dispersant application has changed platform in recent years with the introduction of worlds first jet platform; a Boeing 727 complete TERSUS dispersant delivery system. During development this platform, stringent measures were imposed to comply aviation standards, necessary obtain approval from authorities operate. Airframe icing occurs when ambient temperature is low enough allow water vapour visible moisture form layer ice on unprotected surface, can occur temperatures between 10°C and −40°C. A feasibility study was completed investigate affects it could have operations fixed spray boom. The approved for flights known (FIKI), boom not included within approval, meaning installed, restricted operation these conditions. With new platforms being developed regulatory requirements be met, challenges faced alleviate crucial remove residual risk unable This poster looks at change design ‘fixed' details how OSRL proceeded project identify risks, mitigations route restrictions.
