Photogrammetric Take-off and Landing Measurements
This is a 1929 NACA technical memorandum on photogrammetric measurement of aircraft take-off and landing, issued by the NASA Technical Reports Server collection for engineers and aeronautical researchers. The first page shows instrument photographs with dial gauges, a tripod-mounted camera-like device, and field test settings, while the second shows a geometric diagram and two plotted graphs of speed and height against distance. A designer might draw from the crisp line diagrams, the sepia photographic panels, and the grid-plotted charts as clean technical documentation motifs.
