4 - The ideal wind speed for hot air balloon flights - To provide the best conditions for a safe balloon flight landing the maximum surface wind speed on the day of the balloon ride must not exceed 10 miles an hour.
A common speed limit encountered by all aeroplanes is the restriction to fly at 250 knots (288mph) or less when under an altitude of 10,000 feet, which falls into the Class B airspace level. In some cases the Class B level can extend a little higher.
