Test 10 Questions Quiz BPL Gas - Balloon Pilot License - Flight Performance and Planning, no time limit

1 - What effect has the elevation above MSL of an airfield on the carrying force and maximum take-off mass of a balloon?
2 - Given the following masses: Empty mass 260 kg Instruments 20 kg per gas container (full): 30 kg per person: 80 kg Assuming temperature ISA+10, how many persons may be carried in the basket at maximum, if the balloon with 4 gas containers has to climb up to pressure altitude 12.000 ft ?

3 - While overflying a waypoint, it is stated that a distance of 2 NM has been taken 10 min. What will be the expected time of endurance for the complete distance of 18 NM?
4 - What is the purpose of "interception lines" in visual navigation?
5 - At time of take-off, ground wind speed is 3 m/s. Along take-off flight path, at a distance of 360 m obstacles erect up to 40 m. What is the minimum rate of climb to keep a clearance of 50 m above the obstacles? (Consider double the ground wind speed for the flight path)
6 - While overflying a waypoint, it is stated that a distance of 3 NM has been taken 10 min. What will be the expected time of endurance for the remaining distance of 18 NM?
7 - Before take-off, the balloon pilot realises that the maximum take-off mass has been exceeded by 5%. What has to be done?
8 - At time of take-off, ground wind speed is 3 m/s. Along take-off flight path, at a distance of 270 m obstacles erect up to 40 m. What is the minimum rate of climb to keep a clearance of 50 m above the obstacles? (Consider double the ground wind speed for the flight path)
9 - What effect has the elevation above MSL of an airfield on the carrying force and maximum take-off mass of a balloon?
10 - Given the following masses: Empty mass 240 kg Instruments 20 kg per gas container (full): 30 kg per person: 80 kg Up to which pressure altitude can the balloon climb with 5 persons and 4 gas containers in the basket, assuming temperatures 10° below ISA?
