34. Unless otherwise authorized by the airport manager, no person shall drive a motor vehicle on an apron at a rate of speed in excess of 15 mph (25 km/h).

(2) Every Class C ship propelled by internal combustion machinery shall, in the compartment containing that machinery, be provided with a fixed gas smothering system that complies with the requirements set out in Schedule III, except that where the machinery space is so open to the atmosphere as to make the use of a fixed system ineffective, no such system need be fitted.

Air Canada's Boeing 777 engines are sent to Air France, where the three services are centralized: the company takes care of engines, the aircraft and their components.

Sampling points targeted at the protection of vegetation and natural ecosystems shall be sited more than 20 km away from agglomerations or more than 5 km away from other built-up areas, industrial installations or motorways or major roads with traffic counts of more than 50 000 vehicles per day, which means that a sampling point must be sited in such a way that the air sampled is representative of air quality in a surrounding area of at least 1 000 km. A Member State may provide for a sampling point to be sited at a lesser distance or ...[+++] to be representative of air quality in a less extended area, taking account of geographical conditions or of the opportunities to protect particularly vulnerable areas.

Sampling points shall in general be sited in such a way as to avoid measuring very small micro-environments in their immediate vicinity, which means that a sampling point must be sited in such a way that the air sampled is representative of air quality for a street segment no less than 100 m length at traffic-orientated sites and at least 250 m × 250 m at industrial sites, where feasible.
