Possible Hypoxia at Altitude
Practice communicating this situation: While cruising at altitude, you notice difficulty concentrating and blurred vision.
Your scenario
You are flying Evektor, registration N827EV. Your position is 12 miles east of Paine Field, indicated altitude 3500 feet. You are tuned to Seattle Approach. Your planned destination is Arlington.
Practice goals
- While cruising at altitude, you notice difficulty concentrating and blurred vision. You remain able to control the airplane and communicate, but continued flight at this altitude feels unsafe. The cause is unconfirmed.
- State the problem and requested assistance without inventing aircraft handling or a successful outcome.
Respond aloud during each ten-second practice window, then compare with the example. Replay any exchange you want to practice.
