This is the operator's rules, applicable to dispatch the A/C. No legal reasons to get ATC dragged into this, or put it into the flight plan. Only on the OFP it must be.
True or false?
Engine failure may be one reason....
For IFR flights, the pilot-in-command shall specify at least one weather-permissible take-off alternate aerodrome in the flight plan if the weather conditions at the aerodrome of departure are at or below the applicable aerodrome operating minima or it would not be possible to return to the aerodrome of departure for other reasons.
