You don’t grab the controls to raise a concern — you climb a ladder of clarity, one firm rung at a time.
A junior crew member who spots a problem faces a real bind: stay silent and the risk grows; over-react and you undercut the captain over nothing. Graded assertiveness solves it with a ladder. You start with a gentle probe, then get firmer — alert, challenge — and only declare and act as a last resort.
The anchor is the two-challenge rule: if you clearly challenge a decision twice and get no adequate response, you presume the leader has lost the picture and you intervene. The captain’s job is the mirror image — invite the challenge, verbalise the plan, and never punish a good-faith flag.
Fly the challenge · unstable approach
Your move — pick a rung
Ladder climbed: —
Each rung says the same concern more plainly and leaves the leader less room to brush it off. You climb only as far as you need, escalating as time and altitude run down:
Probe a question that makes the leader notice "Do you see we're high?"
Alert name the concern and your discomfort "I'm not comfortable with this."
Challenge state the required action, directly "Captain, go around."
Emergency presume lost picture — act "Going around." (you fly it)
In the simulator the captain’s willingness to abandon the approach builds with each firmer message — and it crosses the line on your second clear challenge. That is the two-challenge rule, made visible:
willingness needed to go around ............ 100
probe +15 running total 15
alert +30 running total 45
challenge +45 running total 90 (challenge #1 — still fixated)
challenge +45 running total 135 -> over 100: captain calls the go-around
two clear challenges, no adequate response -> you are cleared to declare & act
| Rung | Reach for it when… |
|---|---|
| Probe | You first notice the deviation and there’s time — a question invites the leader to self-correct without a confrontation. |
| Alert | The probe didn’t land. Naming your discomfort raises the stakes while still respecting authority. |
| Challenge | Safety is now at risk. You state the required action plainly — no hedging, no hint. |
| Declare & act | Last resort. Two clear challenges got no adequate response, or there’s no time left. You act. The trade-off: use it early and you’ve lost the crew for a challenge that would have worked. |
An interviewer asks: “Tell me about a time you had to push back on someone more senior.” Walk the ladder. You noticed a client deck cited a revenue figure the night before the pitch (probe: “Is this the number from the latest close?”). The lead waved it off, so you alerted: “I’m not comfortable presenting a figure I can’t stand behind.” Still no fix, so you challenged plainly: “We need to correct slide 6 before this goes out.” When that landed, they fixed it — no controls grabbed, relationship intact. The structure is the answer: you escalated deliberately, gave the leader every chance to self-correct, and had a clear line where you’d have taken it to their manager.

You’ve now challenged twice — “Captain, go around” — and gotten no adequate response as the runway rushes up. What does the two-challenge rule ask of you?
