Its wing has a 3 ft ( 910 mm ) greater span, with vortex generators over the whole upper leading edge, and the fin is square cornered and 8 in ( 200 mm ) taller.

During installation of the Aviation Partners Inc . winglets ( as the G-IISP ), the vortex generators and midspan fence were removed and replaced with six leading edge vortilons similar to those found on the Gulfstream IV.

An ATR-42 had shown problems with ice buildup while on autopilot in 1988, and to solve the problem the FAA ordered installation of devices on the wings called vortex generators to prevent dangerous changes in air flow.

This is the principle behind the dimpling on golf balls, as well as vortex generators on aircraft . Special wing sections have also been designed which tailor the pressure recovery so laminar separation is reduced or even eliminated.

An ATR-42 had shown problems with ice buildup while on autopilot in 1988, and to solve the problem the FAA ordered installation of devices on the wings called vortex generators to prevent dangerous changes in the air flow.
36.
To simplify construction the wing has no washout and instead has two composite vortex generators of a unique design, outboard on each wing, to ensure that the inboard portion of the wing stalls first, thus retaining aileron control through the stall.
37.
An ATR-42 had shown problems with ice buildup while on autopilot in 1988, and to solve the problem the FAA ordered installation of devices on the wings of the ATR-42 planes called vortex generators to prevent dangerous changes in the air flow.
38.
The IX MR retained the features of the Evolution VIII MR, like Bilstein shocks, a 6-speed manual transmission, a rooftop vortex generator, BBS forged wheels, HID xenon headlights, foglights, accessory gauge package, " zero lift " kit, special badging and an aluminum roof.
39.
One the most important applications of metasurfaces is to control the wavefront of electromagnetic waves by imparting local, gradient phase shift to the incoming waves, which leads to a generalization of the ancient laws of reflection and refraction . vortex generator, beam deflector, axicon and so on.
40.
After 1991, the airworthiness certification requirements in the USA specify the one-engine-inoperative climb requirement as a gradient independent of stalling speed, so there is less opportunity for vortex generators to increase the maximum takeoff weight of multi-engine airplanes whose certification basis is FAR 23 at amendment 23-42 or later.
