What do spoilers do on a glider?

What do spoilers do on a glider?

Spoilers were used by most gliders (sailplanes) until the 1960s to control their rate of descent and thus achieve a controlled landing. Since then spoilers have almost entirely been replaced by airbrakes, usually of the Schempp-Hirth type. Spoilers are used to increase descent rate without increasing speed.

Are spoilers speed brakes?

Spoilers and Speedbrakes are secondary flight control surfaces that can be deployed manually by the pilot or, under certain circumstances, that extend automatically. Speedbrakes are purely drag devices while spoilers simultaneously increase drag and reduce lift.

Is the 767 400 Safe?

The 767 is one of the strongest and safest airliners ever built. When we test it and the 777, we inflate the cabin with pressure equivalent to flying to 80,000 feet. We do this to every airplane to make sure it will be safe at high altitude.

Why are there spoilers on a Boeing 767?

A view of the right wing of a Boeing 767-300ER during descent with spoilers partially deployed. Spoilers deployed to slow down for descent on a Qantas Boeing 737-800. Extended spoilers are intended to increase the lift-induced drag by spoiling the spanwise lift distribution across the wing.

How long has the Boeing 767 been in production?

The Boeing 767 has been in production now for 33 years and was planned to be phased out and replaced by the very popular Boeing 787 Dreamliner. The 787 suffered many delays and some airlines chose to take the Boeing 767 300ER in its place as they could no longer wait.

What kind of engine does the Boeing 767 have?

The Boeing 767 is a mid- to large-size, mid- to long-range, wide-body twin-engine jet airliner built by Boeing Commercial Airplanes. It was Boeing’s first wide-body twinjet and its first airliner with a two-crew glass cockpit. The aircraft has two turbofan engines, a conventional tail, and, for reduced aerodynamic drag, a supercritical wing design.

Who are the subcontractors for the Boeing 767?

Production and testing. To produce the 767, Boeing formed a network of subcontractors which included domestic suppliers and international contributions from Italy’s Aeritalia and Japan’s CTDC. The wings and cabin floor were produced in-house, while Aeritalia provided control surfaces, Boeing Vertol made the leading edge for the wings,…
