Pilot workload is reduced with five functions of Davtron's Model 655. Davtron’s Model 655 is a computer-based product that computes density altitude automatically. No longer does the pilot need to retrieve outside air temperature and pressure altitude, then enter this into a flight computer. The Model 655 measures outside air temperature, and accepts pressure altitude information from the blind encoder or encoding altimeter, then converts this information to a direct read-out of density altitude. The density altitude is computed using U.S. standard atmosphere tabulation. Take-off roll, maximum rate of climb, and fuel consumption are determined easily from density altitude and the aircraft’s flight manual.
A single push-button on Model 303 causes the digital display in automatic rotation to show its three functions of: voltage, outside air temperature (Fahrenheit), outside air temperature (Centigrade). When the radio master switch of the aircraft is first turned on, The Model 303 always readsout the aircraft voltage to the nearest tenth of a volt. A code letter E indicates it is in the voltage function (EMF). To display outside air temperature in degrees Fahrenheit, the button is pressed, and the letter F appears to indicate this mode. The next press of the button displays C for outside temperature in degrees Centigrade.
