Definition
Airspeed restrictions, beyond those marked on the airspeed indicator, that apply to specific aircraft configurations or operations. These include limits such as maximum landing gear operating speed, maximum landing gear extended speed, maximum flap extended speed, maneuvering speed, and best rate or angle of climb speeds. They are published in the Pilot's Operating Handbook (POH) or Airplane Flight Manual (AFM) rather than shown by color-coded arcs on the airspeed indicator.
Plain English
Speed limits that aren't painted on the airspeed indicator dial but that the pilot still has to respect. They're listed in the aircraft's handbook and apply when doing certain things, like extending the landing gear or flying through rough air.
Context Anchor
Seen in the aircraft operating handbook, cockpit placards, and airspeed limitation discussions when checking what speeds are safe or legal for a specific aircraft.
Derivation
“Limitation” comes from “limit,” meaning a boundary. In this context, it helps to think of the speed as a boundary the pilot must stay within, not as a rough suggestion.
Why Pilots Care
Exceeding these limits can cause structural damage, loss of control, or unsafe flight conditions, so pilots must observe them during every phase of flight involving configuration changes.
Intuition Check
“Other” does not mean less important. “Limitations” does not mean helpful advice; it means published operating boundaries for that aircraft.
Example Sentence 1
Before extending the gear, the pilot slowed to below the maximum landing gear operating speed listed in the POH.
Example Sentence 2
During the preflight briefing, the instructor reviewed the other airspeed limitations for gear extension on the training aircraft.
