Hot air balloons have a gas heater attached to them the pilot can turn the heater on the balloon and the balloon will go high why?

Hot air balloons have a gas heater that is generally powered by propane. When the pilot turns the heater on, the balloon will fly high due to the hydrocarbon chamber that allows the pilot control of ascent and descent of the hot air balloon.

If the air balloon needs to carry more people. how can the pilot get the heavier load off the ground?
I think it drops the ballast (sand filled bags) which are attached to the basket
How do you land a hotair balloon?
Well All hot air balloons have a variable release valve in the top of the balloon which the pilot can use to control the altitude of the balloon..This valve when opened to a certain point allows hot air to slowly escape from the top of the balloon and the balloon will slowly decend,the exchange is controlled so the balloon maintains its size...by use of the release valve and the burners the pilot can control the rate of decent to a nice soft landing....The release valve is also used to quickly deflate the ballon once it has landed...
What are the disadvantages of hot air balloons?
Hot air balloons have no forward propulsion or steering mechanism. The pilot only has control over the vertical travel of the aircraft. In order to achieve travel in any given direction, the pilot must find an altitude in which the wind is blowing the desired direction. There is a large amount of luck involved in navigating a hot air balloon. Hot air balloons can be extremely difficult to launch and/or land, and doing so safely requires a large team of personnel.
How does a hot air balloon maneuver?
Piloting a balloon takes skill, but the controls are actually very simple. To lift the balloon, the pilot moves a control that opens up the propane valve. This lever works just like the knobs on a gas grill or stove: As you turn it, the flow of gas increases, so the flame grows in size. The pilot can increase the vertical speed by blasting a larger flame to heat the air more rapidly.Additionally, many hot air balloons have a control that opens a second propane valve. This valve sends propane through a hose that bypasses the heating coils. This lets the pilot burn liquid propane, instead of propane in gas form. Burning liquid propane produces a less efficient, weaker flame, but is much quieter than burning gas. Pilots often use this second valve over livestock farms, to keep from scaring the animals.Hot air balloons also have a cord to open the parachute valve at the top of the envelope. When the pilot pulls the attached cord, some hot air can escape from the envelope, decreasing the inner air temperature. This causes the balloon to slow its ascent. If the pilot keeps the valve open long enough, the balloon will sink. Essentially, these are the only controls -- heat to make the balloon rise and venting to make it sink. This raises an interesting question: If pilots can only move hot air balloons up and down, how do they get the balloon from place to place? As it turns out, pilots can maneuver horizontally by changing their vertical position, because wind blows in different directions at different altitudes. To move in a particular direction, a pilot ascends and descends to the appropriate level, and rides with the wind. Since wind speed generally increases as you get higher in the atmosphere, pilots can also control horizontal speed by changing altitude.
Why does a hot air balloon need ballast?
Hot air balloons DON'T need any ballast. However gas balloons which get their lift from lighter-than-air gases, typically helium or hydrogen, do need ballast. The ballast allows the pilot to control the altitude at which the balloon flies. To gain altitude the pilot releases some ballast or vents out some gas to descend. During flight some gas will be lost through natural losses through the material of the gas envelope and the pilot counters the loss of lift by releasing ballast to maintain the altitude he wants. On long distance flights the variation between night and day time temperatures affects the amount of lift the gas exerts of the balloon. This requires further adjustment of gas venting or release of ballast to maintain the desired altitude.
What are people driving hot air balloons called?
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.
What does a air balloon tattoo mean?
An air balloon tattoo may mean that a person likes air balloons. It may also mean that they pilot air balloons.
What makes hot-air balloon drift downwards?
Balloons start to lose altitude when the air inside the envelope cools off. In order to keep the balloon aloft the balloon pilot uses a burner to heat up the gases inside.
What is free lift in pilot balloon?
The free lift of the Pilot Balloon is defined as the difference between the total lift and the weight of the balloon and its load. The free lift is really the net buoyancy of the balloon. Thus free lift is the force tending to drive the balloon (Hydrogen filled) upward, which depends upon the amount of hydrogen gas filled in it. If a hydrogen balloon is inflated until it floats with certain weight attached to it, than it indicates that the attached weight balances the upward force acting on it. This weight is called free lift of the balloon and if weight is removed, the balloon rises up (with fixed rate of ascent corresponding to weight attached while inflating).
What is a hot-air balloon pilot called?
A hot air balloon pilot is called an aeronaut.
Does a tethered helium balloon require a licensed pilot?
Yes. The pilot has to obtain atleast a Bronze certificate to pilot the balloon alone.
How does a balloon pilot control BOTH acsent and descent of a balloon?
A balloon pilot controls ascent by heating the air inside the balloon with a burner and descent by allowing the air to cool or venting it.
What is the name for the pilot of a hot-air balloon or light aircraft?
The pilot is just 'the pilot'

Why do hot air balloons fly at high altitudes?
Hot air balloons can fly at almost any altitude they choose. The height of the balloon flight is determined primarily by the pilot. Most balloon flights are tourist sightseeing flights or just fun flying by sport pilots. These flights are typically performed between 500 and 2000 feet above the ground. Also balloons must comply with the air traffic control regulations which limit where and how high balloons may fly unless they carry special navigation and communication equipment. On November 26, 2005, Vijaypat Singhania set the world altitude record for highest hot air balloon flight, reaching 21,027 meters (68,986 feet) above sea level. This flight was done in India under special permission from Indian authorities using a specially designed hot air balloon. Don Boyer Hot Air Balloon Pilot New Mexico, USA
