Pilot's tip of the week

Flying By Trim

Featuring

Subscriber question:

"Some pilots are told by their instructors to fly by the trim. My instructor religiously says to trim after you find your appropriate angle of climb, descent, or cruise. Which is true, and which is false?" - Craig T.

Bob:

The idea is to trim off control pressures after power and attitude are set. Attempting to fly the aircraft with trim will result in a wide divergence of airspeed and trim before the proper setting is achieved. Trim tabs are not a primary flight control. Remember that trim is both power and airspeed sensitive. Therefore trim can only be accurately set after the power and airspeed stabilize. This applies in climbs, cruise, and descents.”

(NEW) VFR Mastery scenario #95 “Iconic Adventure” is now available. You’re a sport pilot who took a friend for a day of splash and dashing in your Icon A5. After lunch, you met some folks with an XCub on amphibs, and your friend got some stick time with the pilot of that plane, who is also a CFI. Unfortunately, the XCub got stuck on the runway where you were supposed to swap passengers. After some loitering, there’s a plan to move it, but the clock is ticking toward civil twilight—after which you can’t legally fly. Pretty soon you won’t have time to get home. Is there a way to retrieve your friend without excessive risk or busting a reg? Watch the Intro video.
