there is a rope, much like the rope truckers pull for their horns, that you pull down, opening a flap on the top,letting the warm air out. this allows them to float back to earth...
By releasing some of the hot air in a very controlled manner.
What they do is blast cold air into the "hot" air and it makes the air molecules slow down... Thus it makes the air balloon decrease back to earth.
Hot air balloon pilots control the descent of the balloon by releasing hot air and using vents to control the descent rate. They aim to land in a suitable location, often communicating with a ground crew to assist in the landing process. Once on the ground, the crew helps to pack up the balloon for transport back to the launch site.
Hot air balloon pilots use propane to heat their balloons. It's inexpensive, very easy to obtain, and works.
Escaped balloons can only rise to the altitude where they are the same density as the surrounding air; they cannot go into space. Eventually the helium leaks out and they fall back down.
In the United States, a pilot of a hot air balloon must have a pilot certificate from the FAA and it must carry the rating of "Lighter-than-air free balloon", and unless the pilot is also qualified to fly gas balloons, will also carry this limitation: "Limited to hot air balloons with airborne heater". A pilot does not need a license to fly an ultralight aircraft, but training is highly advised, and some hot air balloons meet the criteria. To carry paying passengers for hire (and attend some balloon festivals), a pilot must have a commercial pilot certificate. Commercial hot air balloon pilots may also act as hot air balloon flight instructors. While most balloon pilots fly for the pure joy of floating through the air, many are able to make a living as a professional balloon pilot. Some professional pilots fly commercial passenger sightseeing flights, while others fly corporate advertising balloons.
a hot air balloon only works using thermals, which are currents of hot air rising because one area is heated more than the others. so hot air balloons depend on air to keep it airborne, specifically hot air. once it leaves the earths atmosphere, it is a vacuum. there is no air, so the hot air balloon will fall back into the earth. hence, we see that hot air balloons cannot leave the earth's atmosphere.
Pilots steer hot air balloons primarily by controlling the altitude of the balloon, as horizontal movement is largely dependent on wind currents. They can ascend by heating the air inside the envelope with a burner and descend by allowing the air to cool or by releasing hot air through a vent at the top of the balloon. By changing altitude, pilots can navigate different wind directions at varying heights, allowing them to steer towards their desired destination. However, precise steering is limited, making careful planning and understanding of weather patterns essential for successful navigation.
Yes, navy pilots and air force pilots are military pilots.
Hot air balloons typically fly in the troposphere, which is the lowest layer of Earth's atmosphere. This layer extends from the Earth's surface up to an average altitude of about 8-15 kilometers. The temperature decreases with altitude in the troposphere, which helps to create the temperature difference necessary for hot air balloons to generate lift.
Hot air balloons descend by either releasing hot air from the envelope or by using a vent at the top to let cool air in. Pilots can control the descent rate by adjusting the amount of hot or cool air in the envelope.
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
