Definition
The performance-based restrictions placed on an aircraft's operation, derived from flight testing and certification, that define the conditions under which the aircraft can be flown safely and legally. These limitations cover takeoff and landing distances, climb performance, weight, altitude, temperature, runway requirements, and obstacle clearance, and are published in the Aircraft Flight Manual (AFM) or Pilot's Operating Handbook (POH).
Plain English
The official limits on how, where, and when an aircraft can be operated, based on what it has been proven to do during testing. These limits tell the pilot whether a planned flight is within the aircraft's capability for the conditions of the day.
Context Anchor
Seen during instrument flight planning and procedure review, especially when checking whether the aircraft can safely depart, climb, approach, or go around under the current conditions.
Derivation
“Limitation” comes from the idea of a boundary or limit. In this term, it helps to think of these as operating boundaries, not rough suggestions.
Why Pilots Care
Exceeding these limits can cause runway overruns, insufficient climb performance on a missed approach, or loss of control.
Grounding Statement
Before trusting the aircraft to meet a procedure, the pilot checks that the flight stays within the performance limits the aircraft was approved to meet.
Intuition Check
Do not read “limitations” as general advice or normal best practice. In this context, they are approved operating boundaries that affect whether the aircraft can safely perform the required task.
Example Sentence 1
Before departing the high-altitude airport on a hot afternoon, the pilot reviewed the aircraft performance operating limitations to confirm the runway was long enough for a safe takeoff.
Example Sentence 2
High density altitude forced the crew to reduce takeoff weight so the aircraft would remain within its performance operating limitations.
