1. Fly inexperienced, nervous, and nausea-prone passengers only under smooth conditions — if this means going earlier or later in the day, or even postponing the flight, so be it.
2. Keep your cockpit temperature cool. (Again, this may mean flying early or late in the day.) I counsel my passengers before takeoff to advise me if they feel warm. If that happens I open all the vents and have them remove any outerwear. Sometimes it helps pressing a cold can or bottle from the cooler against the face, and I have been known to open windows in flight to cool things off. If someone does get sick, getting them promptly on the ground is usually the best cure.
3. When possible, point out anticipated bumps ahead of time (like under windy conditions, downwind of ridges, flying low over barren or paved terrain in summertime, in the vicinity of cumulus clouds, etc.). When passengers know turbulence is coming and see that you can predict it, they are less bothered by it.
4. Keep your feet firmly on the rudder pedals during turbulence to counteract yaw. Since the center of gravity in most light aircraft is near the front seats, yaw in turbulence is generally far worse in the back seat. So in addition to serving as a human yaw damper, put your least-experienced or most nervous passenger in the front seat.
5. During the preflight briefing say something like, “you’re not likely to get sick on this flight, but on the rare chance you do get uncomfortable, there are sick sacks located here… Keep in mind that there is nothing embarrassing about using a sick sack if you need it. It’s not using one that’s embarrassing!” Say it with a nonchalant smile on your face, but say it!
6. Most importantly, if a passenger does get sick, do not get distracted from flying the airplane! Your passengers’ safety is more important than their comfort! (For a story about the hazards of this, see “Bowling Alley Hot Dogs” in my book, Flying Carpet.)
7. Many pilot friends report good results with ginger chews to relieve/prevent nausea. If all else fails, have your passengers see their pharmacist or doctor for one of the very effective oral and skin-patch over-the-counter anti-motion-sickness meds. (Most if not all of these are not FAA-approved for pilots, so be sure to check in advance if relevant.)
8. Sinus and ear congestion can cause vertigo, so flyers and passengers suffering such symptoms should appropriately pre-medicate to relieve symptoms before flying. (Pilots within FAA guidelines, of course.)
Finally, I’d like to offer encouragement that if airsickness plagues you as a new pilot, be patient. Your “air legs” will rapidly improve the longer you fly. Almost no one is entirely immune to occasional discomfort if it’s hot and bumpy enough, but as pilot and passenger experience grows such discomfort grows exceedingly rare. Again, the trick is to keep your temperature down. In summertime always carry ice water in your cockpit; a touch to the face with a cold bottle or a few sips will help keep you and your passengers from overheating.
