When a plane is going into land the computerised voice thing is calling out numbers.... why does it say MINIMULS, MINIMULS just before touch down?

  1. M&Ms?


  2. "Minimums" is plural.  On a precision instrument approach it is a callout at decision height which prompts the pilots to consider the minimums [(1) the aircraft's height and (2) the minimum flight visibility for continuing the approach] and decide to continue the approach or fly the missed approach procedure.  The (DH and visibility) minimums are given on the approach procedure chart.  [Seeing the runway is not required in order to continue the approach below DH].  

    If you heard "Minimums" shortly before touchdown maybe the pilot was using an Instrument Landing System.  

    "ILS Minimums

       1.  The lowest authorized ILS minimums......are:

       Category I.  Decision height 200 feet and Runway Visual Range 2400 feet;

       Category II.  DH 100 feet and RVR 1,200 feet.

       Category IIIa.  No DH, or DH below 100 feet and RVR not less than 700 feet.

       Category IIIb.  No DH, or DH below 50 feet and RVR less than 700 feet......

       Category IIIc.  No DH and no RVR limitation."

    Military pilots can have a ceiling minimum, too.  

    Many approaches in Latin America (especially Brazil)  also specify a ceiling minimum.

  3. the guy who answered first is right it says 'minimums'.

  4. It actually says "Minimums". The decision altitude for the approach (that is, the height by which the pilots have to see the runway) is programmed into the aircraft computers, and when the aeroplane reaches that height, it announces "minimums", because by that point the pilots need to have made a decision as to whether they intend to land or do a missed approach.
