August 4, 2011 – Last week while all eyes were on AirVenture Oshkosh, ICON Aircraft tested a new spin-resistant wing design that does not include flaps or wing cuffs for its A5 amphibian LSA. The flight occurred July 28 and is part of a design enhancement that ICON says will reduce aircraft complexity and improve safety. The new wing design will allow pilots to maintain control even through an inadvertent stall, while the flaps were removed because LSA speed restrictions mostly negated their benefit on the aircraft.
“Although these enhancements are not required by the FAA or ASTM … it make[s] it simultaneously one of the safest and easiest [aircraft] to fly,” said ICON CEO Kirk Hawkins. ICON also features an Angle of Attack (AOA) indicator, which, combined with the new wing, will keep the wings level in the event of a stall, the company says. According to ICON, the removal of the flaps was to reduce complexity since LSA are required to stall no faster than 45 knots without flaps.
On the same day of the wing test flight, ICON also announced at AirVenture a partnership with Horizon Hobby to sell a line of R/C models of the ICON A5. The launch model, which was on display in Oshkosh, is being sold under Horizon’s ParkZone brand and is currently available for purchase with shipping beginning in September.
