The track-line on the Electronic Horizontal Situation Indicator (EHSI) or Navigation Display of an Electronic Flight Instrument System:
In the conventional MLS path-geometry model, without DME/P the approach is normally:
With otherwise comparable low-altitude LF/MF groundwave conditions, coastal-refraction bearing errors are typically most significant when the NDB is:
A VOR is sited at position A (45°00'N, 010°00'E). An aircraft is located at position B (44°00'N, 010°00'E). Assuming that the magnetic variation at A is 10°W and at B is 15°W, the aircraft is on VOR radial:
An aircraft is flying on a heading of 270°(M). The VOR OBS is also set to 270° with the full left deflection and FROM flag displayed. In which sector is the aircraft from the VOR ground station?
A pilot flying an aircraft at FL 80, tunes in a VOR which has an elevation of 313 m. Given ISA conditions, what is the maximum theoretical distance at which a pilot might expect to receive the VOR signals?
The OBS is set to 235°. The indications of the VOR are half full scale deflection left and 'to'. The aircraft is on the radial:
A typical frequency employed in Distance Measuring Equipment (DME) is:
The aircraft DME receiver cannot lock on to interrogation signals reflected from the ground because:
For a civil aircraft with conventional VOR/DME equipment but no TACAN azimuth receiver, a compatible military TACAN station can provide:
