Definition
A pre-computed engineering study, performed for a specific aircraft type at a specific runway, that determines the maximum allowable takeoff weight and the procedure to follow if an engine fails after V1, ensuring the aircraft can either stop on the remaining runway or continue the takeoff and clear all obstacles along a defined departure path with one engine inoperative.
Plain English
It is a runway-by-runway calculation done in advance that tells the crew the heaviest weight they can safely take off at, and the exact path to fly if an engine quits, so the aircraft will still clear terrain and obstacles on the remaining engine.
Context Anchor
You will see this term in turbine and multi-engine operations when planning a takeoff from a runway that may be limited by runway length, obstacles, temperature, or engine-out climb performance.
Derivation
Analysis comes from a Greek idea meaning to break something apart to understand it. That fits here because the takeoff problem is broken into pieces: the airplane, the runway, the weather, the weight, and the obstacles.
Why Pilots Care
It confirms the aircraft meets regulatory climb requirements and clears all obstacles if an engine fails after liftoff.
Grounding Statement
Before takeoff, the analysis answers the practical question: if an engine fails at the worst time, can this aircraft still stop or continue safely from this runway?
Intuition Check
Do not read “analysis” here as a casual look or general opinion. In this context, it means a specific performance calculation using the aircraft, runway, weather, and obstacle information.
Example Sentence 1
Before departing the mountain airport, the crew checked the airport/runway analysis and found their takeoff weight was limited by obstacle clearance on the engine-out departure path.
Example Sentence 2
Airport/runway analysis showed the climb gradient was sufficient to clear the terrain beyond the runway end.
