qualifying in a hot air balloon and a pilots license.
Yes, you need a Balloon Pilot Certificate issued by the Federal Aviation Administration in the USA. Yes, you need a Balloon Pilot Certificate issued by the Federal Aviation Administration in the USA.
yes
Yes, if the craft is manned- or even carries animals- i was thinking of a sky-born type of Hat-trick with Rabbits, perhaps. The FAA requires a specialized balloonist or Balloon pilot license for all manned aerostation-Balloon flight except a captive or tethered balloon which does not really fly but is suspended on cables.
it took about a year for the first hot air balloon to be made.
If you have children, it should be illegal to have a balloon ready to jump into and take off.
yes
Yes. You have to have a Pilot's license. And usually a radio license to be able to communicate with any airports in the area.
No, a hot air balloon does not need CO2 to lift. Hot air balloons work on the principle that hot air is less dense than cooler air, causing it to rise. When the air inside the balloon is heated, it becomes lighter than the surrounding air, allowing the balloon to lift off the ground.
a hot air balloon
To weigh air in a balloon, you would first need to weigh the balloon when it is empty. Next, fill the balloon with air and weigh it again. The difference in the weights would give you an approximation of the weight of the air in the balloon. However, this method would not provide an accurate measurement of the weight of the air due to factors like the weight of the balloon material and the presence of air inside the balloon.
A hot air balloon needs a flame to heat the air inside the balloon, making it less dense than the surrounding air. This temperature difference creates lift, allowing the balloon to float upwards. Without the flame, the air inside the balloon would cool down and the balloon would descend.
