Development

The two-seat DV20 Katana was based on the Super Dimona and was produced in Austria by HOAC (later changed its name to Diamond Aircraft). The Katana first flew in 1991 and gained certification in 1993.[2] The Katana was first shown in public at the 1993 Paris Air Show[3]

The company built a factory in Canada to produce the DV20 which was designated the DA20. The first DA20 was the Rotax 912 powered A1 Katana produced in Canada in 1994. It was the first Diamond aircraft available for sale in North America. Production of the Continental IO-240-B3B powered C1 Evolution and Eclipse models began in 1998, also in Canada. Production of the A1 Katana is complete but the DA20-C1 is still being constructed in 2010.[4]

The DA20-A1 and C1 are both certified under CAR 523[5] in Canada and under FAR 23 in the USA. The DA20 is certified in the utility category, and it is permissible to intentionally spin it with flaps in the full up position.[6] In 2004, Diamond received Chinese certification for the DA20. Both models also hold JAA certification.[7]

Although the DA20 is available with instrumentation and avionics suitable for flight under instrument flight rules (IFR), its plastic airframe lacks lightning protection and thus does not qualify for IFR certification.[8]

Design

The Katana is a low-wing cantilever monoplane with features control sticks (as opposed to yokes), composite construction, a bubble canopy, low-mounted wing, a single fuel tank, a T-tail, and a castering nosewheel. All models have composite airframes constructed of glass- and carbon-fiber reinforced plastic.[8] The nose wheel of the DA20 is not linked to the rudder pedals and turns while taxiing are made with differential braking, with rudder steering becoming more effective as airspeed increases.[9]

The Katana possesses a higher glide ratio than many of its competitors. The glide ratio of the DA20-C1 is 11:1 and the DA20-A1 is 14:1.[10]

In November 2008 the company announced that it would be offering an Aspen Avionics glass cockpit primary flight display as an option on the DA20. Diamond indicated the Aspen PFD was easy to incorporate into the existing instrument panel design because it mounts in a standard round instrument hole. In October 2009 the company introduced the Garmin G500 glass cockpit as an option.[11]

Operational history

United States

Embry-Riddle Aeronautical University provided the Academy Flight Screening (AFS) program for the United States Air Force Academy in DA20-C1 Falcons, which were specially ordered with slightly smaller fuel tanks to save weight and primary flight instruments on the right side of the aircraft. Embry-Riddle operated a fleet of DA-20s at the Academy.[12] The AFS program was discontinued in 2007.

Doss Aviation, under contract for the United States Air Force, currently operates a fleet of DA-20s at the Pueblo Memorial Airport in the Initial Flight Screening (IFS) program.[13] Potential USAF Pilots, Combat Systems Officers, and RPA pilots that do not have a private pilot's license must go through the Doss screening program and receive time in the DA20 before going on to their respective training programs.[14]

Variants

A DA-20A-1 in 2002
DV20-A1 Katana
Austrian-built development of the Rotax 912 and certified in 1993[15]
DA20-A1 Katana
Canadian-built DV20. Powered by a 80 hp (60 kW) Rotax 912 and introduced in 1995[15]
DA20-100 Katana 100
Factory refurbished and re-engined Katana for the European market. Powered by a 100 hp (75 kW) Rotax 912S. Introduced in 1999.[15]
DA20-C1 Katana and Katana Eclipse
Name used in marketing and some 1998 year model planes. The name "Katana" was actually painted on some planes. Powered by a 125 hp (93 kW) Continental IO-240 engine. In order to accommodate the extra 70 pounds of the IO-240, the Katana's battery was moved behind the baggage bay, to help move the empty cg aft, and the wing sweep has been changed from 1 degree aft to just 0.5 degrees back to shift the center of lift forward. Previous Katanas had simple hinged flaps — but at the higher maximum weight, more sophisticated slotted flaps were necessary to bring the stall speed to the JAR-VLA-specified 45 knots[16]
DA20-C1 Evolution
Stripped down C1, intended for flight schools as a trainer. No rear windows. Powered by a 125 hp (93 kW) Continental IO-240-B engine[15][16]
DA20-C1 Eclipse
Better equipped C1 for private use, with rear windows for better visibility. Powered by a 125 hp (93 kW) Continental IO-240-B engine Entered production in 1999.[15][16]
DA20-C1 Falcon
Military trainer version. Powered by a 125 hp (93 kW) Continental IO-240-B engine. Instruments moved in front of the right seat, where the student sits. This puts the stick in the student's right hand and throttle in the left, similar to fighter aircraft. Also equipped with a smaller fuel tank. Some Embry-Riddle Falcons have been sold to private owners and flight schools after being fitted with standard instrument panels and fuel tanks.[16]
