According to OPS regulations, for operations under IFR or under VFR over routes not navigated by reference to visual landmarks, the minimum navigation equipment is:
  • A
    One VOR receiving system and one DME.
  • B
    One ADF system and one DME.
  • C
    One VOR receiving system and one ADF system.
  • D
    One VOR receiving system, one ADF system and two DME.

AMC2 CAT.IDE.A.345 Communication and navigation equipment for operations under IFR or under VFR over routes not navigated by reference to visual landmarks
ACCEPTABLE NUMBER AND TYPE OF COMMUNICATION AND NAVIGATION EQUIPMENT

(a) An acceptable number and type of communication and navigation equipment is:

(1) one VHF omnidirectional radio range (VOR) receiving system, one automatic direction finder (ADF) system, one distance measuring equipment (DME), except that an ADF system need not be installed provided that the use of ADF is not required in any phase of the planned flight;
(2) one instrument landing system (ILS) or microwave landing system (MLS) where ILS or MLS is required for approach navigation purposes;
(3) one marker beacon receiving system where a marker beacon is required for approach navigation purposes;
(4) area navigation equipment when area navigation is required for the route being flown (e.g. equipment required by Part-SPA);
(5) an additional DME system on any route, or part thereof, where navigation is based only on DME signals;
(6) an additional VOR receiving system on any route, or part thereof, where navigation is based only on VOR signals; and
(7) an additional ADF system on any route, or part thereof, where navigation is based only on non-directional beacon (NDB) signals.


Note that there are 2 versions of this question:

  • One where the correct option is "One VOR receiving system, one ADF system, one DME."; and

  • this one, where the correct option is "One VOR receiving system and one DME."

ADF is not part of the standard equipment ("S"). However, it is still required to be carried as a basic navigation equipment device, unless the flight is operated along a route where NDBs are not available.
