Plain English Meaning
Landings are where most training accidents happen, so the instructor has to keep the flight safe while still letting the student learn. This means watching closely, setting clear limits ahead of time, knowing when to step in, and teaching the student to spot trouble themselves.
Full Definition
An instructional approach in which the flight instructor actively identifies, assesses, and mitigates the elevated hazards present during landing instruction, while simultaneously teaching the student to recognize and manage those same hazards. It includes setting clear personal and student limits, briefing go-around criteria, monitoring student performance for signs of task saturation, and being ready to take the controls when safety margins are eroding.
