THE US Government is concerned about airlines being required by certain countries to spray aircraft cabins with insecticide just before arriving. More than a dozen countries in Latin America, as well as Australia, New Zealand and some Caribbean destinations follow the practice, which is aimed at preventing pests entering that might pose an agricultural threat. The insecticide, d-phenothrin, is not considered highly toxic to humans. However, it has caused reactions in sensitive passengers. US officials believe the risk to passengers outweighs the benefits against insects. The Transportation Department plans to require US airlines to warn passengers at the time of booking that the insecticide will be sprayed prior to arrival. ALWAYS wanted to take the cockpit controls? Well, you can at Zurich Airport. Unfortunately, though, you won't become airborne. Swissair has made a surplus flight simulator available to the general public for hourly rental. A Swissair pilot and instructor are made available to explain the various controls. Flying buffs are able to simulate take-off, landing and other manoeuvres. The simulator can be hired for SF500-800 per hour (HK$2,600-$4,150). Airline pilots now complete most of their training using simulators.
