Design and development

The Topaz is a development of the Ekolot JK-05L Junior and was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever high wing in place of the Junior's strut-braced wing, a two-seats-in-side-by-side configuration enclosed cockpit, fixed tricycle landing gear and a single engine in tractor configuration.[1][2]

Like the Junior, the Topaz is made from composites. Its 10.76 m (35.3 ft) span wing employs an NN-1817 airfoil, has an area of 10.24 m2 (110.2 sq ft) and flaps. Dual 35 litres (7.7 imp gal; 9.2 US gal) fuel tanks are located behind the seats. A ballistic parachute is an available option. The standard engine available is the 80 hp (60 kW) Rotax 912UL four-stroke powerplant.[1][2][3]

The use of a one-piece wing without struts gives the Topaz a 20 km/h (12.4 mph) higher cruise speed than the Junior, while resulting in the same empty weight.[1][2]

The Topaz has been accepted by the US Federal Aviation Administration as a light-sport aircraft.[4]

gollark: ↓ you
gollark: As can be seen, I have demolished all objections and thus am right.
gollark: This can be shown to be valid:
gollark: I CLEARLY said `= (maybe)`.
gollark: However, apiohax = P = (maybe) NP = 0 (mod N). Therefore, as rings may be noncommutative, it is the case that the left ideal, 7, is an eigenvalue of the matrix expansion of the general bee formula. By basic applications of previously proven lemmas, it can be shown that this makes apiohax isomorphic to the group (ℤ, +). The implications are obvious.
