Operational Procedures - BPL Hot Air - Balloon Pilot License

Question 1

At temperature below 0 °C the pressure at the burner is at 0.2 MPa (2 bar). Is take-off permissible with the hot air balloon?

Accepted Answer

No, pressure at burner is too low

Answer

Only with double-burner system installed

Answer

Yes, at low temperatures a low hull temperature is sufficient

Answer

Yes, not a problem

Question 2

At high altitude, the complete heating system of a hot-air balloon fails. What maximum rate of descent has to be expected upon reaching ground?

Accepted Answer

Approximately 6.5 m/s

Answer

Approximately 2.5 m/s

Answer

Approximately 4.5 m/s

Answer

Approximately 8.5 m/s

Question 7

What action has to be considered by the pilot of a hot-air balloon with a double-burner installation, in case one burner valve fails?

Accepted Answer

The ride can be continued by use of the remaining burner

Answer

An emergency call should be made

Answer

Both burner valves have to be shut down immediately

Answer

The ride has to be stopped immediately

Question 8

What is the consequence if the pressure at the burner valve is lower than 0.28 MPa (lower than 2.8 bar)?

Accepted Answer

Take-off is prohibited

Answer

The gas container should be heated by the flame

Answer

The heating system may be damaged

Answer

The pressure in the gas container may be increased by use of acetylene

Question 9

What has to be considered at moderate wind speeds during a balloon ride across mountainous area with cloud-free sky?

Accepted Answer

Lee waves and severe up- and downdrafts

Answer

Decreasing burner power

Answer

Altimeter indication too low

Answer

Icing conditions

Question 10

What has to be expected by the balloon pilot during descent in deeply cooled layers close to the ground?

Accepted Answer

Floating on top of the cold air layer

Answer

Balloon starts to climb

Answer
