IFR Minimum Equipment

EU Nr. 800/2013 will supercede national regulations (if they existed before) and this is  a big step towards simpler and better rules for General Aviation. It will become effective by 25.08.2016 in Switzerland. The important parts concerning IFR minimum equipment of EU Nr. 800/2013 for airplanes are as follows:

NCO.IDE.A.125, IFR minimum equipment in Switzerland:

  1. magnetic compass
  2. clock* displaying h, min, s
  3. altimeter
  4. airspeed indicator
  5. vertical speed indicator
  6. turn and slip indicator
  7. attitude indicator
  8. directional gyro
  9. outside air temperature
  10. vacuum pressure gauge
  11. pitot heat

NCO.IDE.A.190, Radio communication equipment required:

  1. two-way radio if required by airspace or stations (at least one 8.33Mhz spaced radio)
  2. radio which is able to reach 121.5 Mhz
  3. when more than one comm is required they have to be independent

NCO.IDE.A.195, Navigation Equipment required:

  1. navigation equipment enabling to proceed according to ATS flight plan and airspace requirements (except VFR by reference to landmarks)
  2. sufficient navigation equipment to have a backup (e.g. two VORs, VOR/ADF, VOR/IFR GPS, etc.)
  3. if landing in IMC, the applicable equipment for the approach

NCO.IDE.A.200, Transponder:

  1. Transponder if required by the airspace.

Thanks to the high regulatory burdens that used to exist, most Swiss general aviation aircraft should be able to receive their IFR certification they intially had when the airplane had been built (look up your airplane’s Type Certificate Data Sheet, TCDS, in CFR23 or CS-23 certification). Remember, what’s legal isn’t necessarily safe. Plan your flight according to the equipment you have. With the minimum IFR equipment you might be limited to fair-weather IFR with just a few stratus clouds to climb through.

*EASA accepts a wrist watch to fulfill this requirement, see Consolidated (unofficial) AMC&GM to Annex VII (Part-NCO)

    Hi Florian, I see a vacuum gauge as part of the IFR min equipment list, but what if the aircraft has no vacuum system? Does one just need a gauge stuck in a hole in the panel with nothing behind, with the indicator fixed in the green zone ??? 😉

    1. Hi Vince

      Good idea! Not sure if your mechanic would sign that off, though… 😉

      I probably over-simplified what NCO.IDE.A.125 actually says. In proper EASA English the regulation says, quote: a means of indicating when the supply of power to the gyroscopic instruments is not adequate;

      I suppose you always have some kind of indication, even with ram air suction. Never flew with anything other than electric gyros w/ INOP flag and vacuum gyros with vacuum gauge.

      Thanks for your comment!
