How do you steer a balloon?
Before the hot air balloon flight all the safety precautions must be taken by the pilot of hot air balloon. The pilot get all the related information regarding hot air balloon from different sources, like from government or private reports about weather. Before the hot air balloon flight pilot releases small helium balloons in the air to determine the wind direction and speed.
After anaylizing all the information like weather condtions and as well as the actual condition that he observed regarding hot air balloon flight, the hot air balloon pilot will make a decision to fly or not as well as selecting a launch site appropriate for that flight. The hot air balloon floats with the wind or you can say that according to the direction of the wind, the Pilot knows which direction the hot air balloon will travel so the launch site is selected which will allow the balloon to fly into an area with appropriate landing sites.
Once airborne, the pilot can move the balloon up and down to utilize the varying directions of wind to change course. Some time the change in direction of wind is quite significant, while at other times there may be little or no change in direction at any altitude. All these factors are taken into account when the pilot determines if the flight will take place or not.
There are even days when there may not be enough wind movement above the earth to fly at all. If there is little or no wind, or if the wind direction is constantly changing, the pilot may decide it isn’t safe to fly. If the balloon just sits overhead with little movement, it may be very difficult for the pilot to find a suitable landing spot.
