AIR LAWS

A helicopter is on a 150 NM leg to an off-shore oil rig. Its TAS is 130 kt with a 20 kt tailwind, its endurance is 3h30min without reserve. Upon reaching destination, it is asked to proceed outbound to locate a ship in distress, on a track which gives a 15 kt tailwind. Maintaining zero reserve on return to the oil rig, the helicopter can fly outbound for distance of:

• A 160.3 NM
• B224.5 NM
• C158.6 NM
• D222.1 NM

On the readability scale what does ""readability 1"" mean ?

• AUnreadable.
• BReadable.
• CPerfectly readable.
• DReadable but with difficulty.

The procedure to be followed in the event of decompression when flying above 10,000 ft must :

• Aallow for the rapid supply of oxygen in order to prevent the pilot becoming hypoxic
• Ballow for a rapid descent independent from sufficient supply of oxygen in order to prevent disorders due to hypoxia
• Cmake it possible to prevent hyperventilation owing to the inhalation of 100 % oxygen
• D make it possible to eliminate the risk of fogging due to the sudden pressure changes
