12 Advertisements. FLIGHT JUNE I6TH, 1949 EXIT THE ASTRODOME Xhe introduction of the HUGHES PERISCOPIC SEXTANT, designed especially for pressurised aircraft, heralds the exit of the astrodome. In its place a sextant mounting is built into the aircraft as a permanent fixture. This has a sealing piece interconnected with safety locks to hold the sextant in position and maintain cabin pressure. The sextant itself is a portable unit stowed in a transit case when not in use. In operation the periscope tube protrudes only three inches above the skin of the aircraft. When the sextant is retracted the sealing piece is flush and streamlined with the aircraft's skin. Literature describing the Hughes Periscopic Sextant is obtainable on request.
