Ace the Skies with FAR 135 Oral Test 2026 - Elevate Your Aviation Dream!

The activity authorized is conducting a pretakeoff contamination check. This specification allows an operator to perform a procedure before takeoff to verify that the aircraft is free of ice, frost, snow, or other contaminants on critical surfaces and air data sensing equipment that could affect performance and safety. It ensures that airspeed indications and control effectiveness will be reliable for takeoff, especially in icing or potential contamination conditions.

The other items listed aren’t what this Ops Spec covers: they relate to other areas (weight and balance programs, security screening, or oxygen requirements) that aren’t authorized by this particular specification.
