rules to play hot air ballooning

Preflight preparation
1. Before a safe hot air balloon flight can begin, the pilot must check the weather and select a suitable take off point. The current and forecast weather must have sufficient visibility for the pilot to see and avoid obstructions (little or no fog or low clouds) and sufficiently slow winds to allow take off and landing (less than 5 or 10 mph depending on skill and experience of pilot, passengers, and ground crew).The take off point must be large en .....
Set up
2. The next step in a hot air balloon flight is unpacking the balloon from its carrying bag, laying it out on the ground, and connecting it to the basket and burner. A fan, often gasoline powered, is used to blow cold (outside) air into the envelope. The cold air partially inflates the balloon to establish its basic shape before the burner flame is aimed into the mouth heating the air inside. A crew member stationed opposite the mouth, holds a rope .....
Flight
3. During the flight, the pilots only ability to steer the balloon is the ability to climb or descend into wind currents going different directions. Thus, it is important for the pilot to determine what direction the wind is blowing at altitudes other than the balloons altitude. To do this, the pilot uses a variety of techniques. For example, to determine wind directions beneath the balloon a pilot might simply spit or release a squirt of shaving cr .....
Control
4. The direction of flight depends on the wind, but the altitude of the balloon can be controlled by changing the temperature of the air inside the envelope. The pilot may open one or more burner blast valves to increase the temperature inside the envelope, thereby increasing lift, and thus ascend or slow or stop a descent. The pilot may also open a vent, if the envelope is so equipped, to let hot air escape, decreasing the temperature inside the en .....
Delayed response
5. One of the tricks involved in flying a balloon is learning to deal with the delayed response. To slow or stop a descent requires the pilot to open a burner blast valve. This sends hot combustion exhaust through the mouth into the envelope where it expands and forces some cooler air out of the mouth. This lightens the total weight of the system and increases its buoyancy, but not immediately. From the time that the burner is lit until the balloon .....
Steerage
6. The ability to change direction with altitude is called steerage. In the ideal case, in the northern hemisphere, wind direction turns to the right with an increase in altitude. This is due to the Coriolis effect. Winds spiral clockwise, when seen from above, out of a high pressure system and counter clockwise into a low pressure system. However, air traveling close to the ground will tend to move in more of a straight line from high to low pressu .....
Level flight
7. The burner is designed to create enough heat to warm up the balloon quickly. It is most efficient only when wide open. There is no good way to maintain the exact temperature required to maintain equilibrium. Add to that the fact that when a hot air balloon is not actively being heated, it is cooling off. This means that it is in perfect equilibrium only momentarily. The rest of the time it is either too warm or too cool and so either climbing or .....
Chase
8. While it is certainly possible to enjoy the sport of hot air ballooning without a chase vehicle, returning from the landing site by foot, bicycle, or hitch hiking, many balloonists opt to be followed by their ground crew in some sort of chase vehicle. Crew at the landing site can aid with the landing itself, by catching a drop line and guiding the balloon into a tight space; with extracting the balloon system from a remote location, such as deep .....
Landing
9. Most pilots try to perform as smooth a landing as possible. This becomes difficult if the air at ground level is moving at more than 5 mph (2.2 m/s) or so. If the balloon is moving at this speed or more when it contacts the ground, the basket (which usually does not have wheels of any kind on the bottom) may drag for a bit or even tip over. Even the presence of ground crew may not help much. The combined weight (for an average passenger carrying .....
Competition
10. In competition, the pilots need to be able to read different wind directions at different altitudes. Balloon competitions are often called races but theyre most often a test of accuracy, not speed. For most competitive balloon flights, the goal is to fly as close as possible to one or more exact points called targets. Once a pilot has directed the balloon as close as possible to a target, a weighted marker with an identifying number written on it .....
Hazards
11. The dangers of the sport include excessive (vertical or horizontal) speed during landing, mid air collisions that may collapse the balloon, and colliding with high voltage power lines. It is the last of these, contact with power lines, that poses the greatest danger. One of the most common causes of serious ballooning accidents in the US is power line strikes. One reason for the high frequency of such incidents is the fact that pilots often attem .....
Night flight
12. In the United States, the FAA requires balloons to fly under visual flight rules. If equipped with lights that make it visible to other aircraft, balloons can fly in the dark. However, such flights are usually limited to either dawn patrol flights that begin before sunrise with landings made after there is sufficient light to see any obstacles or to race/record flights that typically go throughout the night and the landing again made during dayli .....
Winter flight
13. The ability to fly hot air balloons in the winter is limited mostly by the ability of the participants to withstand the cold. The balloons themselves fly well in cold air. Because the temperature difference between inside and outside the balloon, not the absolute inside temperature, determines the lift it develops, a much lower internal temperature is sufficient to fly in cold weather.However, if the liquid propane in the fuel tanks is too cold ( .....
Tethering
14. Sometimes, especially at balloon festivals or other special events, balloons are flown while tied to the ground with ropes (tethers). This enables quick rides to many passengers, instead of long rides drifting with the wind away from the event with one load of passengers. Tethering techniques depend on the balloon manufacturers instructions and wind conditions. Tethers can be attached to the basket, burner support, or the top of the envelope. A n .....
Winds aloft
15. The winds on the surface are just one of our concerns. We have to think three dimensionally and consider what the wind is doing at altitude as well. This is perhaps the most confusing aspect for our passengers. There is not even a hint of a breeze on the ground and your flight has just been cancelled due to wind, how come? We look at winds at the surface (the wind you can feel) and the winds at 1 to 9,000 feet. We are not going to 9,000 feet, bu .....
Poor visibility
16. How far can we see? Our aircraft are designated by the Federal Aviation Administration (FAA) as Visual Flight Rules (VFR) certified. That means we must have a certain amount of visibility to fly legally. The visibility must be 1 to 3 miles, depending on where we are flying. If we dont have it, we cant fly. .....
Rain and storms
17. The decision not to fly in rain or storms seems a simple one of course we dont! What isnt so simple is why your flight may be cancelled when no storm or rain actually happens in the area. We must often make our decision based on a forecast. Despite the many advances in weather prediction, forecasting remains an imprecise science. We often refer to forecasts as horoscopes with numbers. Our idea of long range forecasting is 4 hours and we dont pl .....

Balloon fiesta
19. The Albuquerque International Balloon Fiesta is a world renowned attraction and destination for kids of all ages. For more than three decades, the first week in October brings the smell of roasting chiles and the beautiful, magical moving picture show of hot air balloons sailing silently through the crisp fall air. Guests from all over the world come to Albuquerque to celebrate ballooning. Literally hundreds of balloons will be taking flight from .....
Temperature
20. Since hot air balloons fly by changing the temperature inside the balloon with heat, it stands to reason that outside air temperature is going to affect balloon flights, and it does! When the air in the balloon is heated, it becomes hotter and thus less dense than the surrounding outside air. This hotter air is lighter and the balloon will float upward. The more heat, the higher up you go. A balloon will fly when its temperature is around 140 deg .....
Weather sources we use
21. We use a vast array of sources to arrive at our go, no go decision. Most of our information comes from FAA mandated briefing sites that require a pilots license to access and a log in. You should know that we are required, by Federal Air Regulations, to obtain a complete weather briefing prior to every flight. Many passengers obtain their own weather information from one of the many sites available on the internet we encourage you to t .....
Events
22. There are many regular gatherings of balloons and balloonists around the world. Most of these events are held on an annual basis. The festivities provide both a place for balloonists to interact as well as a venue for entertaining spectators. Events range in size from a few balloons and no spectators to hundreds of balloons with hundreds of thousands of spectators. Two such events are the Albuquerque International Balloon Fiesta and the Bristol B .....
Eligibility
23. Open only to legal residents of the 50 United States and the District of Columbia (U.S.) and Canada (excluding Quebec) who are 18 years of age or older at time of entry. Employees, officers and directors of Albuquerque Convention And Visitors Bureau, Simpleview, Miles Media and McKee Wallwork and company (the Sponsor), its parents, subsidiaries, affiliates, advertising and promotion agencies, webmasters/suppliers, and members of the immediate fam .....
Hot air balloon physics operation
24. If the balloon operator wishes to lower the hot air balloon, he can either stop firing the burner, which causes the hot air in the envelope to cool (decreasing the buoyant force), or he opens a small vent at the top of the balloon envelope (via a control line). This releases some of the hot air, which decreases the buoyant force, which also causes the balloon to descend. To maintain a steady altitude, the balloon operator intermittently fires a .....
Hot air balloon physics analysis
25. Lets examine the physics of a hot air balloon using a sample calculation. The heated air inside the envelope is at roughly the same pressure as the outside air. With this in mind we can calculate the density of the heated air at a given temperature, using the Ideal gas law, as follows: P = ?RT Where: P is the absolute pressure of the gas, in Pa ? is the density of the gas, in kg/m3 R is the gas constant, in Joules/kg.K T is the abso .....
