What is the difference between soaring and gliding
While gliding, one does have some control over their movements, however not too much. Once something is launched in the air, it may change direction or manipulate its movement to change its landing point.
Once we launch it, it usually flies straight, however, at times it may land halfway across the room from where we intended. We might have been aiming at the table, but it may land on a chair opposite the table. This is mainly because either the direction of the air changed or the position of the airplane change. In any case, the movement changed the relation of the air currents and the airplane.
Hence, the airplane was forced to follow the air current or if it was opposite the air current, then it would have just crashed. While, almost all birds fly, there are many that glide from one place to another over short distances, usually from one tree to another.
They do this by just extending their wings and allowing the air current to carry them. There are also some mammals that glide from one tree to another. A prime example of this is the flying squirrel, wrongly named as it does not fly but glides. Soaring, on the other hand, is a state of flight exercised by many different birds. Have you ever seen a bird high up in the sky, all alone and it seems to be flying without flapping its wings.
That bird is actually soaring. Soaring can be used to describe two different types of flying patterns. What they often do not realize is that when flying from the back seat, there are no flight instruments, just a second microphone jack for the radio. You do not need instruments, you can get all your information from looking outside, the noise, and the feel of the controls.
It gives a great sense of freedom from "things"; you only have wings. There are also unexplained phenomena. Once I encountered a very brutal bump, so sharp I was glad to be tied to the glider by a four-point harness, in air that was otherwise quiet. Also, towards the end of one day, in ultra-smooth air above a marshy park, I was drifting down lazily at minimum sink rate towards the airport, except that the altitude would just not wind down.
I thought the altimeter had jammed, but no, for half an hour I remained at the same altitude, not in a thermal, but possibly in humid air released from between the trees. Some benefits of Soaring Soaring is one of the few human activities where the older you get the better you are at it; where else can an year old repeatedly beat a year old? I always viewed this activity as ideal for retirement but living in the USA, I don't know if I'll ever be able to afford to retire It also puts a welcome pressure on the pilot not to gain too much weight over the years, as there is a payload limit for all gliders.

Beyond decision-making, it is also learning to partition what is important from what is not, especially for details. I consider a Glider Pilot license to be a requirement for the good education of children. Flying gliders is actually much more fun than flying airplanes with the exception of flying seaplanes, but that's another story. If I had to do it all again, I would never have learned to fly powered airplanes and also saved significant monies.
In Europe, flying gliders is much more common than flying airplanes, mostly because of cost. In the USA, it is the opposite; it is the glider pilots who are the happy few. If you also fly powered planes, flying gliders will definitely make you a better pilot.
Even the infamous "engine failure" becomes trivial. When extending the dive brakes on a Schweizer trainer, you happen to glide down at the same vertical speed and airspeed as a Cessna without power. It is a good exercise to reach the runway after having promised yourself not to retract the dive brakes until a few feet above the runway.
Engine failures become second nature in no time. Some dangers of Soaring I am often asked if flying gliders is dangerous. I used to reply with the classic "driving to the airport is more risky", but now I say that "you can make it as dangerous as you want". When in competition or trying to break some record, one is naturally prone to stretch limits and gamble with marginal odds, although in Illinois the whole countryside is a runway. On the other hand, training and judgment can also make soaring very safe.
What most car drivers do not realize is that cruising along a road lined with trees, turning the steering wheel a couple degrees, and hitting one, survival is very unlikely. This is the same in gliders, if you do not control your pitch within a couple of degrees when about to land, you are not likely to survive either. As a glider pilot driving a car, now I instinctively see trees, bridges, utility poles, and parked cars along the road as deadly reinforced concrete pillars.
Also, you have no control on the many drunk and other rogue drivers, even if you drive perfectly yourself. A glider crash or even a plain off-airport landing will make the front page of the local newspaper, yet in the USA car accidents kill 40, people a year without a second thought. My th glider flight had an exciting moment. Dragged down to a pattern altitude, I hit a strong and narrow updraft and decided to go for it. Banking at 60 degrees to remain in the narrow core, the glider suddenly got spat out of the thermal.
No more wind noise, no pressure on the controls, full stall. I remember clearly looking straight down at corn stalks, with more curiosity than disbelief. Training pays off in those rare occasions. Seeing the familiar earth drop away and become ever smaller creates a profound feeling of awe as your sailplane climbs toward the clouds. And the clouds themselves take on new meaning and importance as the earth becomes divided into friendly areas of lift or unfriendly areas of sink.
The pilot can enjoy a special kind of relaxation, too. The gain in altitude seems to leave mundane cares on the surface of the earth far below. It is an exercise in relativity: a sailplane typically sinks feet per minute about 2 mph through the air that surrounds it.
If that air is moving upwards faster than 2 mph, the glider rises relative to the ground. In the early s, glider pioneers were doubtful that consistent large upward currents of 2 mph could reliably develop in the atmosphere and be exploited by pilots. Perhaps soaring was only for the birds, slow and maneuverable as they were.
Once they tried, they soon found out that useful lift is quite common and it is a rare day that a glider cannot do at least a little soaring. Most instructors feel that 30 to 35 flights are the minimum needed for most people with no previous flight experience. An experienced power airplane pilot can generally solo a sailplane in less than 10 flights. Gliders and glider pilots are regulated by the Federal Aviation Administration FAA who set the minimum requirements for pilot certificates.
The cost to become a Private Pilot-Glider varies greatly from person-to-person depending on the amount of time needed to master the necessary skills. In addition, each soaring club offers different rates both for instruction and for aircraft rentals. Call your local soaring club for detailed information.
After solo, student pilots may qualify as a Private Pilot-Glider provided they are at least 16 years of age. Once airborne, a glider or sailplane uses only atmospheric uplift rising air to gain height and can usually fly faster than the wind. Soaring is the art of developing skills and knowledge as a pilot to use this rising air for flight. Jan 8. Southwest Soaring Museum. Jan Sunflower Soaring Center.
