tankers, fuel tanks or fuel storage areas;
(c) persons or cargo;
(d) any other aircraft or aircraft hangar.
Note   For each radar installation the sector area should be defined in terms of readily distinguishable dimensions preferably related to some feature of the aircraft and should appear in the Aircraft Maintenance Manual.
       6.2.2The equipment is not energised with the antenna stationary and the beam directed towards any of the objects specified in paragraph 6.2.1 unless the distance separating them from the antenna is in excess of 60 metres (200 ft).
       6.2.3The distance specified in paragraphs 6.2.1 and 6.2.2 may be reduced by 75 per cent when an approved beam attenuating device is used between the antenna and any object specified in paragraph 6.2.1.
       6.2.4The equipment is not energised in any radiating mode of operation when the aircraft in which the equipment is fitted is in a hangar or other enclosure unless a suitable microwave energy absorbing shield is fitted over the antenna.
       6.2.5The equipment is not to be operated in any aircraft which is being refuelled or defuelled.
Note   During all testing of aircraft radar equipment the beam should, whenever possible, be directed with maximum upward tilt toward a clear area.

Appendix I

Fire safety requirements to be met by mechanical and electrical equipment within 15 metres (50 ft) of an aircraft's fuel tank filling points and vent outlets during fuelling operations

1 Application
      1.1 The requirements of this Appendix are applicable to all mechanical and electrical equipment used within 15 metres (50 ft) of an aircraft's fuel tank filling points and vent outlets during fuelling operations.
      1.2 Compliance with these requirements is the responsibility of the operator of the equipment.

2 Vehicles and plant
Note   Because a higher standard of safety can be more readily achieved on diesel engines than petrol engines, it is recommended that diesel engines be used on all vehicles, pumping plants, etc., used within 15 metres (50 ft) of an aircraft's fuel tank filling points and outlet vents during fuelling operations.
      2.1 All equipment shall be of good automotive design, and shall receive proper maintenance to ensure that it is kept in good state of repair. All reasonable means shall be taken to limit the hazard from fire. Particular attention shall be given to possible sources of ignition such as:
(a) incandescent carbon or naked flame which could be emitted from the engine or associated equipment; and
(b) arcing between metallic parts of electrical circuits and components caused by:
 (i) operation of switch contacts; and
 (ii) faulty cable terminations; and
 (iii) breakdown of electrical insulation; and
 (iv) moving contacts or rotary electrical equipment; and
 (v) accidental short circuiting or open circuiting; and
(c) exposure of hot
