Aircraft stopping distances on wet runways are accurately predicted by measurements taken with a conventional automobile equipped with diagonal braking system and simple instrumentation for recording stopping distances.
Circuit handles data, regardless of polarity and amplitude, in 10-line decimal form or in any form of binary coded decimal. When measuring instruments have common chassis grounds, Zener diodes prevent low-leak circulating currents from unbalancing the circuit.
