Designed by Harris Booth as a torpedo bomber in 1914, the A.D. Seaplane 1000 was a floatplane of wire braced, fabric covered wood construction. An unequal span biplane, the central glazed nacelle housed an engine and pusher propellor. Two tractor engines were mounted in the booms. The undercarriage was two main floats and two smaller rear floats. The outer wing panels had dihedral and were separated on each side by two sets of interplane struts. Overhanging ailerons, on the outboard trailing edges of the upper wing, were supported by kingposts and cables. Seven were ordered from J. Samuel White, but only one was completed. With poor performance further development was abandoned but the single type 1000 survived until 1916.

Designed by Harris Booth of the Air Department of the Admiralty as a single-seat anti-airship fighter, the A.D. Scout – later to become known unofficially as the ‘”Sparrow” – a single-bay staggered biplane intended to carry a Davis two-pounder recoilless gun. The rudders and outsize tailplane were carried by four parallel tailbooms. The gun was intended to be mounted in the bottom of the nacelle, to the tail of which was attached a 100hp nine-cylinder Gnome Monosoupape rotary engine driving a pusher propeller. Construction was of wood with fabric covering, and four prototypes were ordered and built (two by Hewlett & Blondeau and two by Blackburn) in 1915. Delivered to the RNAS, the A.D. Scouts proved seriously overweight and difficult to handle in the air. In consequence, all four aircraft were scrapped.
The narrow track main undercarriage was assisted by the lower booms set approximately 11 feet / 3.35 m apart.

The A.D. Navyplane was designed by Harold Bolas as a two seat pusher floatplane. Two were ordered in January 1916 for the Royal Naval Air Service and serial numbers were allocated for seven (9095-9096, N.1070-N.1074) but only one prototype was completed (9095). It was originally fitted with an American Smith Static ten cylinder single-row engine, and flight tested in August 1916 by Lt.Cdr John Seddon. The engine was later replaced by an AR.1 rotary (later redesignated BR.1 for Bentley Rotary 1) and retested in May 1917. The performance was found to be poor and the aircraft was oficially deleted on 27 August 1917.

Designed in 1915 to serve in patrol and reconnaissance roles, the AD Flying-Boat was a two seat, single engined, unequal-span braced biplane. The wings could be folded for stowage, and a braced ailplane had twin fins and rudders. Construction of two prototypes was begun in May 1915, with May, Harden & May of Southampton building the first hull. The hull being designed by Lieutenant Linton Hope. The first was then completed at Southampton by Pemberton-Billing Ltd, who also built the second prototype and the 27 production aircraft. The first prototype was powered initially by a 200 hp / 149kW Hispano-Suiza with a four blade pusher prop. The original order was for 85 aircraft but after the first 27 the remaining contracts were cancelled in March 1918. The aircraft were used by the Royal Naval Air Service, armed with one forward firing 0.303 in Lewis gun and provision for eight light bombs. All 27 production aircraft were declared obsolete in late 1918. Nineteen were repurchased by Supermarine soon after the war and converted for civil use as the Supermarine Channel.

The Airline Arrow was a 1922 major modification of a Standard J-1 by (John W) Rogers Aircraft Co, Los Angeles, for this aspiring LA-Imperial Valley airline proved unsatisfactory. Seating 8 inside the cabin, it was the second commercial airliner design, after Lawson Air-Liner. It and the fledgling company flew into obscurity in the Depression Era.
The Airdale is the production version of John Larsen’s “Pursang”. John took his original Avid MkIV “Hauler” and highly modified it to suit the 4 cycle, 4 cylinder horizontally opposed 100hp Subaru EA81 auto engine. Engine options now include Continental and Rotax. Modifications to the original Avid included: -Fuselage stretched by 16″ to give better ground handling and CG flexibility. -Two piece, easy to install, 74″ wide track aluminum landing gear. -Re-raked windshield. -Simplified control system which incorporated differential flaperon controls. -Redesign of cockpit structure to remove tubes from behind seats giving easier access to a larger baggage area (55 gal. drum size). -Individual, fully adjustable, easy to remove tilt and slide seats. -Belly structure in footwell area modified to give extra leg and head room. -Double tailspring for better resilience to rough terrain landings. -Wider cockpit and doors to accommodate larger pilot and passenger. -Redesigned cowling to accommodate greater range of engines. -Modifications to Avid wing to increase Gross Weight capability to 1400 lb. -Full stress analysis to comply with JAR regulations at 1400 lb. Maximum Takeoff Weight.
