HC Deb 21 April 1937 vol 322 c1743
43. Mr. Chorlton

asked the Under-Secretary of State for Air, in view of the risks to aircraft from ice, whether he can state to what extent de-icing arrangements have been fitted to the leading edges and control edges of civil aircraft in this country; and whether this practice is a standard one for all machines in the United States?

Sir P. Sassoon

At the present time, eight aircraft on the British register are fitted with de-icing devices on leading edges, six being fitted with the Goodrich device and two with the Dunlop. I should, however, draw attention to the reply which I gave last Wednesday to my hon. Friend the Member for Stroud (Mr. Perkins) in which I explained that deicing problems are at present receiving close attention. The fitting of de-icers on all passenger carrying aircraft is not compulsory in the United States, but I am informed that no aircraft is allowed to fly under known icing weather conditions without equipment approved by the Bureau of Air Commerce.

Mr. Chorlton

In effect, does that not mean that all civil aircraft are fitted with this device? From my own personal experience all that I have seen are so fitted.

Sir P. Sassoon

Unfortunately that has not prevented several very serious accidents taking place in the United States under conditions which are attributable to icing.

Mr. Perkins

Surely any safety device is better than no safety device?
