Two flights for Greg today, both in a DH.6, which was his principal basic training aircraft:
Date: 15.3.18 Hour: 10.30 Instructor: [Thomas] Machine Type and No: DH7666 Passenger: CE Gregory Time: 50 min Height: 1200 Course: [Aerodrome] Remarks: Dual
Flight’s log book entry
Date: 15.3.18 Hour: 5.10 Instructor: [Thomas] Machine Type and No: DH7666 Passenger: CE Gregory Time: 25 min Height: 1200 Course: [Aerodrome] Remarks: Dual
So today was the first day of instruction proper, as opposed to air experience.
Quite possibly it was today that the photograph that’s used for the main image for this blog was taken:
This seems to a posed shot taken of student pilots generally. Greg’s co-student Albert Gertrey is seen here in the same pose, and probably the same aircraft.
The DH.6 was designed by Geoffrey de Havilland, who had moved to The Aircraft Manufacturing Company Limited (‘Airco’). Airco’s successor in business today is BAE Systems, who have this to say about it:
The DH6 was first flown in late 1916 and was an angular tractor biplane with a resolutely rectangular wing plan-form allowing the individual wing panels to be interchangeable. As a result, the 1919 edition of Jane’s All the World’s Aircraft conferred the following description: ‘it has rather the appearance of having been built by the mile and cut off to order’. Performance was limited by the low power and the high drag of the rather crude engine installation.Most aircraft used the Royal Aircraft Factory 1A engine but supply shortages led to the 90hp Curtiss OX-5 and 80hp Renault engine being used is some production batches.The two prototypes A5175 and A5176 were fitted with fins and rudders of the archetypal de Havilland shape, whereas production machines featured a more angular rudder, without an aerodynamic balance.
The type also featured a heavily cambered wing leading edge to ensure benign stalling characteristics. This (and possibly the low performance) led to the type acquiring the soubriquet ‘Clutching Hand’ although many also considered this appropriate due to its forgiving nature when flown by inexperienced pilots. Other nicknames included ‘skyhook’ and ‘flying coffin’ (the latter not on account of its safety record, but rather because of the shape of the cockpit opening). In fact some maverick instructors actually claimed it to be useless as a trainer because it was too easy to fly.At least 2,282 DH6 were built, including those sub-contracted to the following companies: The Gloucestershire Aircraft Co. Ltd; The Grahame-White Aviation Co. Ltd; Harland & Wolff; Kingsbury Aviation Co. Ltd; Morgan & Co. Ltd; Ransomes, Sims & Jeffries Ltd; and Savages Ltd.In 1917, the training role within the RFC was revamped with the aim of making flight instructors into specially trained pilots. After initial use of the DH6, it was replaced with the much larger Avro 504K and surplus aircraft were transferred to the Royal Naval Air Service as anti-submarine patrol aircraft. It was in this role that the DH6 found another surprising accolade as it was found that in the unfortunate occurance of an enforced ‘ditching’, the aircraft remained afloat for up to 10 hours.However, it was severly underpowered which resulted in the majority of convoy escorts being flown solo, a complicated arrangement considering most air to ship communication was via an Aldis lamp. By the end of the conflict over 1,000 aircraft were still in service albeit in second-line roles.
