Who is responsible for making the de-frost/defrost request and when should it be made?

The pilot in command is responsible for initiating the de-ice/defrost process, and that request should be made just before engine start. This ensures the aircraft surfaces are cleared of frost, ice, or snow before any power is applied, which is crucial for safe takeoff and proper performance of flight controls and anti-ice systems. If you wait until after starting the engines, you risk ingesting ice, reduced visibility, or compromised control surfaces, and it can complicate engine startup and performance. Ground crew perform the actual de-icing, but only after the PIC requests it and coordinates with operations; flight attendants don’t handle de-icing, and requesting de-icing after engines are running or by ground crew alone would not meet the safety procedure.
