The Avenger T1 is a standard Beechcraft King Air 350ER (Extended Range) that provides an extra 1,000lb of fuel. Its main modifications are the multimode telephonic radar and internal Tactical Mission Trainer (Air) system.
The squadron's flight hours are contracted to 2,500 hours per year at present, although that may increase to 3,100.
A team of ten experienced Cobham Aviation engineers is responsible for maintaining the four Avengers. Maintenance includes a phase check every 200 hours and four phased inspections.
