Abstract: In considering problems of recording navigational data, the first question to be answered is: Why should such data be recorded? If the navigational problem is considered to be one of merely determining the position of the aircraft at each moment during a flight, it might be argued that continuous indications of such information to the pilot (human or robot) would suffice. This argument is not well received by most navigators, or pilot-navigators, however, since this presupposes that completely reliable automatic navigational computers or radio aids are operative at all times, and that there is no need of keeping a flight log or of having a capability of falling back on dead reckoning techniques in the event of failure of the automatic position indicating devices.
