How should the pilot make a VOR receiver check when the aircraft is located on the designated checkpoint on the airport surface? Operators will have a requirement in their SOPs however. there will be a zero-centered meter. the full-scale deflection is plus or minus one nautical mile, thereby making each dot a fixed-distance deviation of a mere plus or minus 0.2 nautical miles. More modern units are driven by a converter that is standalone or integrated with the radio. When the CDI is centered, the OBS should read _ degrees (FROM), or it should read _ degrees (TO), with a max error of 4 degrees. But, that is academic and does not address the actual question posed.
