This specification covers established metric manufacturing tolerances applicable to copper and copper alloy seamless tubing ordered to metric (SI) dimensions. These tolerances apply to all conditions, unless otherwise noted. The term "exclusive" is used to apply only to the higher figure of a specified range.
This specification covers a nickel alloy in the form of wire, rod, strip, foil, and powder and a viscous mixture (paste) of the powder in a suitable binder. This filler metal has been used typically for joining nonferrous alloys and corrosion and heat resistant steels and alloys where low flow point and corrosion and oxidation resistant joints with good strength at elevated temperatures are required, but usage is not limited to such applications. Also may be used as a corrosion and oxidation resistant hard coating.
This document recommends criteria for the design and installation of Head-Up Display (HUD) systems. The recommendations are applicable to HUD systems which display flight information focused at infinity in the forward field of view. This annex does not address devices for peripheral vision or displays worn by the pilot (goggles, helmet sights).
