Abstract : It was demonstrated that pilots can make takeoffs and landings with a high level of proficiency using a periscope to show flight attitudes and the flight path. Image magnification of the display had little effect on the safety with which pilots made takeoffs. Magnification decreased the accuracy and possibly the safety with which they made periscope landings. Practice in flying by periscope resulted in a rapid improvement in accuracy and in increase in confidence. Flight by periscope is practical and safe at least in slow speed planes. It indicates that a radar or television method for presenting ground reference information offers a practical aid to instrument flight. (Author)
