Three- Engined Aeroplanes [MENT. ")HE completion and initial flying tests of the first Handley Page three-engined commercial aeroplane, which is de scribed and illustrated elsewhere in this issue of FLIGHT, bring into prominence the question of reliability in its relation to economical as well as to safe and regular flying. Although the three- engined type has yet to prove itself in actual every day service, there are both theoretical and sound grounds for believing that this division of the power plant will practically give immunity from total engine failure, and probably immunity from forced landings. This is, of course, merely another way of saying that the safety of flying will be increased, as the risk of a crash on a terminal aerodrome, or even on a properly prepared intermediate aerodrome, is very small indeed. Increased safety is not, how ever, the only gain to be expected from the three- engined arrangement. The very fact that engine failure sufficiently serious to necessitate a forced landing is not likely to occur should mean that, when navigation instruments, turn indicators, etc., are further developed, pilots will be willing to fly in foggy weather, or even at night. The time when that is possible is not yet, but it does appear that the three-engined aeroplane has brought that day con siderably nearer. To this subject we shall return presently. That a price, and a not inconsiderable price, has to be paid for this reliability cannot be denied. Thus, in the case of the Handley Page W. 8 F, the paying load consists of 10 passengers only, with, it is true, rather more than the usual quota of luggage. The total engine power is approximately 800 h.p., so that the horsepower expenditure per passenger carried is 80 b.h.p. This cannot, of course, be regarded as economical flying, but under the peculiar conditions obtaining in the Congo, freedom from breakdown was regarded as of greater importance than economy. In fact, absence of forced landings is essential, and if the price that has to be paid for reliability is high there is nothing for it but to face
