Sir - I refer to the article "UK CAA insists on stick-shaker for Falcon 2000" (Flight International, 22-28 January).

I am particularly concerned with David Antrobus' attitude that "-The CAA [UK Civil Aviation Authority] is in the JAA [European Joint Aviation Authorities] 'club' and in principle it should not introduce any modifications not required by the JAA, unless an accident or incident highlights a specific requirement".

Surely an important piece of safety equipment such as a stick-shaker has been well-proven in the past - and it has obviously been deemed important, otherwise the CAA would not have insisted upon it. I had believed that the notion of waiting for an accident to happen before things were changed had stopped a long time ago.
