Spring is almost here - are you looking forward to landing on soft fields again? If you're planning to touch down on a grass or dirt strip soon, it's time to brush up on your soft-field landing skills. Here's how you'll do it.
How Soft Field Landings
Are Different Soft field landings are pretty much the same as normal landings until you cross the runway threshold. That's where you need to put your soft field landing technique into place.
So what are the steps of a good soft field landing? We'll break it down into three phases: approach to landing, touchdown, and rollout.
Approach To Landing
To make a great soft field landing, you need to start with a stabilized approach. Being stabilized ensures that you touch down where you want, and that you transfer your aircraft's weight from the wings to the wheels as gently as possible.
You should fly your traffic pattern the same as a normal landing. The Airplane Flying Handbook recommends flying your final approach with full flaps at 1.3 Vso, unless your POH recommends a different configuration and speed.
The difference between a normal and soft field landing really comes into play once you cross the runway threshold. That's because as you get close to touchdown, you want to hold the aircraft 1-2 feet off the runway in ground effect.
By holding your plane off the runway, you dissipate your forward speed, and allow your wheels to touch down at a slower speed. This is important for a very good reason: it reduces the nose-over force on your aircraft when it touches down.
Next up is the moment you and your passengers have been waiting for: touchdown. As you enter ground effect, you can use a small amount of power to level off and make sure you touchdown as slow as possible (though power isn't necessary).
Your goal is to fly the airplane to the ground, with your wings supporting the weight of the aircraft as long as possible. Making this happen in a low-wing vs. high-wing aircraft can vary significantly. Low-wing aircraft will have more pronounced ground effect because the wing is closer to the ground, and it may not take as much power manipulation than it will to keep a high-wing aircraft in ground effect.
After your main wheels touch down gently (nice landing, by the way), you want to slowly remove power, if you had any in, and hold the nose wheel off the runway.
Since your main gear are much stronger than the nose wheel, you want to keep the nose off the soft/rough surface until your plane has slowed down to a safer speed. By maintaining back pressure on the yoke, you can hold the nose off until you've reached that safer speed, and your nose wheel will thank you.
You also want to be very gentle on the brakes. On many soft field landings, because of the soft surface, you don't need to use brakes at all. If you're too aggressive on the brakes, your nose wheel tends to touchdown earlier and harder than you want.
Once you've touched the nose down, you'll want to maintain back pressure (typically full back pressure) as you continue your rollout and taxi, minimizing weight on the nose. Keep the back pressure in until you've reached a harder surface, or when you've stopped to park.
Then, when you're parked, take a moment to pat yourself on the back for a job well done on your soft field landing.
