Embraer Executive Jets (Booth N3932) announced Wednesday at NBAA 2015 that its Legacy 450 and 500 received Brazilian ANAC certification for steep approaches. That certification is a prerequisite for similar approvals forthcoming from both EASA and London City Airport (LCY).
The company has been conducting steep approach testing at LCY, where the airport must approve aircraft for both steep takeoffs and approaches, which is part of the airport’s unique noise abatement program. Company sources stated that they expect EASA certification imminently.
LCY is one of a handful of airports around the world that employ steep approaches, in this case 5.5 degrees. The Legacy 450/500 steep approach mode is modeled after that in Embraer’s EJets, except that the Legacy’s system estimates the mass of the airplane for spoiler deflection using flight mechanics formulas based on angle-of-attack and airspeed. It can fly approaches with glideslopes as steep as 7.5 degrees.
