Exam BPL Gas - Balloon Pilot License: Flight Performance and Planning 10 Questions no time limit

1 - What is the purpose of "interception lines" in visual navigation?
2 - After take-off with a balloon, obstacles at a distance of 300 m erect in expected flight path up to 40 m height. Rate of climb is expected with 1.5 m/s. What maximum actual wind speed can be accepted to maintain a clearance of 50 m above obstacles, assuming double the actual wind speed for calculation?
3 - What difference will be experienced during take-off in presence of a strong surface inversion, compared to a take-off with decreasing temperature with height?
4 - What effect has the elevation above MSL of an airfield on the carrying force and maximum take-off mass of a balloon?
5 - A cross-country flight is made using the ICAO 1 : 500.000 aeronautical chart. An overflight crosscheck shows that a distance of 6 cm in the chart has been passed within 9 minutes. After how many more minutes, the overflight of another waypoint at a chart distance of additional 4 cm can be expected?
6 - What must be considered for cross-border flights?
7 - What effect has air temperature on the carrying force and on maximum take-off mass of a balloon?
8 - A cross-country flight is made using the ICAO 1 : 500.000 aeronautical chart. An overflight crosscheck shows that a distance of 4 cm in the chart has been passed within 12 minutes. After how many more minutes, the overflight of another waypoint at a chart distance of additional 6 cm can be expected?
9 - The Empty Mass of a gas balloon includes:
10 - Up to which altitude is an overflight prohibited according to the NOTAM? See figure (PFP-024)
