You are a commander of a flight, where an anti-icing and de-icing procedure has been applied. There is freezing precipitation. Because you have to use a different runway for take-off, there is a delay. You can see a film of contamination on the wing, but the holdover time is not yet exceeded. Your next action is:
  • A
    Switch on all the aircraft anti-icing and de-icing systems until clear of icing conditions when airborne.
  • B
    You taxi back for de-icing and anti-icing.
  • C
    You contact ATC and ask for further advice.
  • D
    You continue to the take-off position and take-off, provided the holdover time is not exceeded.

EASA AIR OPS
Regulation (EU) No 965/2012
CAT.OP.MPA.250 Ice and other contaminants — ground procedures

(a) The operator shall establish procedures to be followed when ground de-icing and anti-icing and related inspections of the aircraft are necessary to allow the safe operation of the aircraft.

(b) The commander shall only commence take-off if the aircraft is clear of any deposit that might adversely affect the performance or controllability of the aircraft, except as permitted under (a) and in accordance with the AFM.

  • In line with the above regulation, any contamination found on the aircraft's surfaces shall be removed by further de-icing and/or anti-icing treatment.

Note: Initially, we received feedback stating that the option "You continue to the take-off position and take-off, provided the holdover time is not exceeded." had been marked correct in official exams. However, we have received inconsistent feedback on this question, and as we do not agree with that answer, the correct option has been changed. Please let us know if you come across this question in your official exam so that we can update it accordingly.
