10If an engine begins to run roughly due to vaporisation of fuel during flight the appropriate pilot action would be

11When increasing power on an engine fitted with a CSU it is good practice to

17Battery compartments are vented because
- Aheat from the battery can cause pressure build up in the compartment
- Bthe battery needs air to help keep it cool
- Cdangerous gases such as hydrogen are released when the battery is charged
- Dvents allow water to drain away from the battery compartment
18Fuel tank vents should be inspected before flight because
