LETTERS One-Eleven maligned SIR —Your timely and infor mative survey "Quiet Jet Rules"; (Flight, December 31, 1983) presents an unjustified condemnation of the BAe One-Eleven in your Table 4: "The Condemned Jets". The factual position, which should be made clear, is as follows: BAe One-Eleven aircraft of all Series with hushkits installed meet Icao Annexe 16 Chapter 2 noise requirements. Series 200 and 400 Series aircraft with hushkits installed also meet American FAR Part 36 Stage 2 require ments (there being no 475 or 500 Series on the US register). BAe One-Eleven aircraft so modified can continue in operation indefinitely within the rules as currently prescribed, and indeed all aircraft deliveries since the end of 1975 have met this standard. Hush-kits have already been installed on, or ordered for, most of the BAe One- Eleven aircraft on the UK register. BAe One-Eleven aircraft operating on the US register are cleared untill January 1, 1988, under the so-called "village airport communities" rules and, if hushkitted, can continue in operation there after. Your Table 4 "Condemned Jets", is therefore incorrect, as it confuses aircraft such as the BAe One-Eleven, which, with hushkits installed, are noise-certificated, with those such as the Trident and Cara- velle, for which no hushkit is available.

February 8 London Society of Air- Britain: Historical aviation film show of wartime films from the Imperial War Pilot's choice SIR—While I can only support the conclusion of your editorial "Blind Leading the Blind" (Flight, December 17), the development you use to come to this conclusion is somewhat ambiguous. In the past 20 years less than 1 per cent of all fatal air accidents were due to Controller error. Nobody cleared the DC-9 into the active runway at Madrid as far as we know, and nobody cleared the 727 into a moun tain or cleared the 747 to take-off at Tenerife. Professional pilots took those initiatives.

But what are "professional pilots" doing flying into that airspace? If you think it is unsafe, refuse to fly there. Ultimate Air Safety does not exist because of the parameters you put into it: rentability, expeditiousness, scheduling, profit, and people. It is all calculated risks, and we all know the rules before hand. If professional pilots are caught taking the wrong risks they should not try to blame their neighbours. Pilots may lose their lives taking those risks, and the controller will spend his time in jail if caught, but it will not stop responsible people from con tinuing to issue recommen dations on how to maintain an expeditious and profitable flow of air traffic in dense fog.
