Hi Milt,
"Anti-Dets" are Anti Deterioration checks. We do them at 14 and 28 day intervals to prevent the aircraft degrading when not in constant flight use. Replenishment of gases and fluids, lubrication and some system run ups to exercise seals and equipments etc. At 28 days we take the aircraft for a wee waddle to the engine running area and run the engines, the Auxiliary Airborne Power unit (AAPP), the Powered Flying Controls (PFCU) and such other systems as/when deemed necessary, e.g. Airbrakes, bomb doors, VHF radios etc, as detailed by the approved schedule from Marshalls of Cambridge.
These anti-dets are performed by TVOC full-time personnel under delegated authorities from Marshalls of Cambridge. All very enjoyable for TVOC engineers and also a part of our ongoing training towards operations in the flying season.
Hope that helps
