INTRODUCTION The purpose of this standard is to assure that new transport type aircraft will provide adequate visibility from the flight deck. A thorough evaluation of the flight deck visibility angles existing in transport aircraft produced up to 1963 was made by SAE Committee S-7@ whose members represent a good cross section of operations personnel of the airlines@ manufacturers@ and general aviation aircraft operators. A philosophy has been generated and is applied throughout the specifications in this document which takes into account the 1963 evaluation of visibility provisions in existing transport aircraft. In addition@ it encompasses the visibility objectives for supersonic transport aircraft including consideration for variable geometry nose requirements. The philosophy is that the minimum visibility provisions must permit the pilot to see that which need to be seen and in useful during any phase of the aircraft's operation@ block to block@ with complete consideration of its geometric features@ operating attitudes@ and speeds. Good visibility in this philosophy is also that which affords an unobstructed view of the flight instruments at the same time that it provides this external vision from the same eye position. In consideration of the Supersonic Transport (SST)@ the following paragraphs 2 through 10 shall apply to all aircraft@ including the SST@ while operating at all subsonic speeds up to at least Mach 0.90. Paragraph 11 applies to the SST while operating at transonic and supersonic speeds. Effective with this revision@ the design objectives in this document which deal with transonic and supersonic portions of the flight operational spectra@ are to be classified as Aerospace Recommended Practice (ARP). The remainder@ which treat the subsonic operations@ will continue as an Aerospace Standard. The latter shall apply to both subsonic and supersonic aircraft while operating subsonically.
