Airmanship emphasis — deciding early
The judgement call in this lesson is when to decide, not how to react to something unmistakable — that's what makes it different from Lesson 17.
Ask — "If you were flying to get home for something important, what's one sign that would make you decide now rather than wait and see?"
Expect — a concrete answer (lowering cloud, reducing visibility, fuel getting tight, daylight running out, an oil pressure that won't settle, a passenger feeling unwell) rather than a generic one. The point is to name the sign while there's no pressure to get home, so it's easier to act on when there is.
Set expectations — tell the student plainly: we're flying today only to practise this, so there's no destination to get to and no reason to rush. Treat it as real: make the decision, make the PAN call, and fly the sequence. Add: if at any point you're uncomfortable, say so — we'll pause, talk, and try again.
Ask — "Talk me through the inspection pattern from memory."
Expect — PAN call and passenger brief, join on the normal crosswind and time the field on downwind, a wider 500 ft pass to time it again, then stay at 500 ft for the circuit, a first low pass ~200 ft to the right of the landing path (full power two-thirds of the way along the runway), circuit at 500 ft, second (dummy) pass ~50–100 ft, decide.
