Using Trim = Smoother Landings

There’s no “perfect way” to trim an airplane. But using trim is an excellent way to reduce your workload in the cockpit, and make your flights more comfortable.

Practice trimming during every phase of flight, so you can fly with fingertip pressure. Just remember that if you’re trimmed for your threshold crossing speed, you’ll need to add extra forward control pressure during a go-around.
