Definition
The procedures, conditions, and precautions a pilot must observe when moving, parking, securing, fueling, or servicing a specific aircraft, as specified by the manufacturer in the Airplane Flight Manual or Pilot's Operating Handbook.
Plain English
The rules the manufacturer gives for how to physically move, park, tie down, and service the aircraft on the ground without damaging it or making it unsafe.
Context Anchor
Seen during preflight inspection, ramp operations, and in the airplane manual when checking how the airplane should be moved, tied down, or serviced.
Derivation
Handling comes from hand, meaning to manage or control something. Requirement comes from require, meaning something that must be done. Together, the phrase points to the required way of managing the airplane safely.
Why Pilots Care
Ignoring handling requirements can damage the aircraft in ways that aren't obvious until flight -- towing past a nose gear's turn limit, lifting at the wrong jack point, or fueling without proper grounding can all create hidden hazards.
Intuition Check
Do not read handling requirements as meaning how the airplane feels in flight. In this preflight context, it means the required ground procedures and precautions for dealing with the airplane safely.
Example Sentence 1
Before towing the aircraft into the hangar, the pilot reviewed the handling requirements to confirm the nose wheel steering limits.
Example Sentence 2
Before takeoff the pilot verified the loading met all handling requirements listed in the POH.
