Side Slipping An Aircraft - The age-old and time-honored art of hacking an airplane to achieve a desired flight path is a great tool to keep in your flight travel tool bag. Once often used to prepare for landing, gliding has become a less frequently used method, mainly because modern aircraft have advanced wings that can be used to increase power during landing. Sideslip is still important for crosswind maneuvering, and glide to landing is reserved for the private pilot test. However, many times pilots do not have a clear understanding of the process.
Open air flights are often flown from the back of the seat, located near or behind the lower wing root. Unfortunately, the pilot's vision during landing was hampered by the combination of wings, wings and wires in front, so it was common to slide sideways during the approach, use the rudder to hold the nose to one side and use the iron. lowering the wings and preventing the rudder from turning. This helped the pilot to see obstacles in the way and adjust the desired attitude. The pilot would then push the rudder back into neutral and level the wings during takeoff, keeping the plane on track by looking at the edge of the runway (the runways were wide and many were the "flying areas" of the day).
Side Slipping An Aircraft
The planes did not need flaps to control the landing, because they had a lot of drag and could land and take off easily. However, when low-glide aircraft became popular, "air brakes" were invented. Today we call them "ends". They loved God because they were able to lower the plane to land and shorten the landing distance. Pilots who were trained to fly, or in the early sons of Piper, who kept the biplane position back-to-back for PIC, still knew how to glide, even after graduating to folding planes.
How Do Planes Land?
Traveling on footpaths could make it difficult to choose which way to go, so crosswinds became a serious problem, so skids were used to prevent the inevitable crosswinds. This requires the use of a sidewall, first touching the bottom of the pneumatic tire. Straight and locked wheels replaced the old tails, and better brakes were developed to help control the ground. When tricycle landing gear replaced the old "regular" gear, pilots began to forget how to use the glider for takeoff and landing, mostly because they didn't need to use it as much as before.
There are two types of hacks, each defined by its purpose and effect, although both require the same control. The forward pitch is used to extend the approach, when the wing flaps are already down and not producing enough thrust, or when there are no flaps for some reason. On the other hand, sideslip is required when strong winds threaten to push the aircraft off the runway or when such equipment can be damaged by strong winds.
Both types of glide require rudder input versus aileron, an unnatural behavior that is often punished with a tongue-lashing from the instructor. However, in this case, crossing is a good thing, because we are intentionally flying out of line to get the right results. Modern aircraft designs, especially the helical gear types, do not get much control power - compared to flywheels, that is because the natural stability of the nose system does not require much control. By reducing the potential for steering, manufacturers can avoid many accidental entry accidents.
Therefore, it is the effectiveness of the rudder that limits the amount of glide that can be achieved, rather than the aircraft's ability to handle inputs. You will be out of control long before you reach the aileron limit.

As a first look at the flight ahead, let's assume we reach an excess of altitude that interferes with our ability to land on the existing runway. We can move to create an additional traffic lane for the next test or add more if available. Or we can try the respectable forward slide, which can save the day.
Since we're already aligned with the runway, we need to turn about 20 or 30 degrees by changing direction, point the nose to one side of the runway, then we'll hold the rudder guide and insert the craft, opposite the rudder. . The aircraft will follow a straight line from the long side of the aircraft, TOWARDS the same flight path as before, hence the name "glide forward". You can see the runway through the side window, but the plane is going that way.
As the aircraft flies sideways through the air, pointing the side of the fuselage towards the direction of the aircraft, more drag is created and downforce increases. Reassure each passenger that this is a normal escape route, as they may wonder why they are throwing the sides of the cabin. If it's not too low, increase the rudder and tiller as needed to handle it. Like we said, you're usually just pushing the steering wheel to avoid stalling at the limit. As you approach the ground or arrive at the runway, release the rudder well enough to allow the nose to swing around the runway and control the wings to descend.
Obviously this is the time to be careful not to stall the plane, as you are flying close to the ground, just reaching the surface. Continue to have the nose stance that was working before entering the pocket and be careful not to increase the offense. If the aircraft has one fixed gate, the airspeed indicator will be affected by the slip; the slope to a fixed spring increases the air pressure on the ram at launch, reducing the airspeed, while the additional slope increases the MSS. Keep the nose down and wait for the airspeed to return to normal as you recover from the glide. Aircraft with dual, rigidly coupled landing gear are not affected by slippage.

Unlike flaps, using forward slip to increase drag means you won't get the benefits of aerodynamic braking when you straighten up on the ground. The plane will stay on the ground until it decides to go down, so you may have to break hard to release it.
Does it matter how you do it forward, left wing down or right wing down? Not really; most pilots, sitting on the left side of the cockpit, push the nose to the right and slide to the lower left wing, for better visibility. And if you make the final left turn, it's natural to recognize the need to slide off and start going directly to the right of the runway. The planes don't care how you sneak. There is a possibility of a fuel tank leak during a short descent if you are foolish enough to descend with less fuel in the tank.
Instead of cloaking the aircraft to do more damage by knocking down obstacles on the approach path, it's also important to use your crosswind control skills. This is the true glide, causing the aircraft to move sideways down the runway in exactly the same direction as the cross section of the storm moves in the opposite direction, while ignoring the wind direction and rolling the landing gear in a straight, nose-down direction. on the center line. The wind tire will be touched first, the lower tire will be removed with the iron input for one second until it vibrates, and the output will continue to apply the control force until the anchors are reached.
Of course, avoiding the "my way is better" argument surrounding storm landings is inevitable. One side insists that there is no need to drop the wings down, that straightening from a crab approach with full boot and rudder down will make for a good touch down. And experts in the art argue and support the final descent with opposing obstacles, following the teachings of the venerable masters who teach the one-wing descent method.
Give It A Tick, Surely It Will Be Fine
The truth is that for those looking for real information, there are several ways to fly and all of them are correct. It is best to consider both methods of dealing with wind resistance when landing, recognizing the advantages and limitations of each. Some aircraft cannot glide aggressively on landing because the gentle slopes or shrouds of the engines reduce the available bank. For them, getting close to the crab and timing the tires to meet the runway is the best way. Multi-powered aircraft have stored inertia that keeps them moving until a collision occurs.
