DEAR SIR, Flight‐Sergeant Wright's article on ‘Flight on asymmetrical engine power’, published in your December issue, dealt with the subject primarily from the point of view of military practice and service aircraft. On the civil side, the ability of transport aeroplanes to perform satisfactorily in the event of engine failure at the critical point at take‐off has for some time not only been a design requirement which has to be met as a condition of certification for new aeroplanes, but also an international operating regulation. It would appear from your leading article that these facts are not generally known.
