pilot balloon

There were two methods of piloting balloons: free flight or captive.

Description: Provides basic pilot knowledge and skills essential for piloting balloons.

Both cuffs are inflated through a single small lumen line and pilot balloon.

He quickly moved on to piloting balloons himself, and shortly thereafter to designing his own balloons.

In addition, it maintains 13 pilot balloon observatories, 10 Rawin stations and 1 Radiosonde station.

Often the operators would first launch a "pilot balloon" and follow its trajectory to see what the prevalent wind and weather would allow.

Examples include pilot balloons (Pibal).

However, during twilight it may be impossible to use the ceiling projector and then a pibal (pilot balloon) light may be used.

He tracked pilot balloons, also known as pibals (balloons used to determine upper level winds), as they rose into the atmosphere.

Also present was Joseph Montgolfier, whom Charles honoured by asking him to release the small, bright green, pilot balloon to assess the wind and weather conditions.

Description: Created by the Federal Aviation Administration (FAA), this handbook is provides the basic pilot knowledge and skills that are essential for piloting balloons.

In addition to surface weather observations, the weather ships would launch radiosondes and pilot balloons, or PIBALs, to determine weather conditions aloft.

The Sky Anchor system, originally developed at Texas A&M University in 1976, is usually applied to unmanned balloons, but the concept was also applied to a piloted balloon.

During the long winter stay, they and two helpers performed 275 pilot balloon soundings, 98 tethered balloon soundings and 19 probe launches with the help of a hang glider.

Barry Bellinger suggests that the telescope was used to track pilot balloons released into the air, before releasing any main balloons; however, a telescope of this size and type seems unsuited to such a task.

Dr. Strong's controversial claim in 1964 of detecting water vapor in the atmosphere of Venus was based on data from instruments he sent to an altitude of 87,500 feet on a piloted balloon.

The pilot will also send up a helium pilot balloon, known as a met-balloon in the UK and pibal in the USA, prior to launch to get information about what the wind is actually doing.

From a site near Mount Fuji, he tracked pilot balloons, also known as pibals (balloons used to determine upper level winds using a theodolite and the balloon's known ascension rate due to its internal gas),Martin Brenner.

The observatory, which was issuing the Madras Daily Weather Report since October 1893 and supplying the time signal throughout the Indian Telegraph system, was reduced to the status of an ordinary pilot balloon observatory in 1931.
