Following are the excerpts from the DGCA circular
Provided that the Pilot-in-Command may permit the use of cellular
telephone by the passengers of a flight after the aircraft has landed and
cleared active runway, except when the landing takes place in low visibility
conditions as may be determined by the Director-General from time to time:
Will someone explain why 'except in low visibility' condition is mentioned ?
Is it because work load on the deck is more due to Low Visibility ?
And if so, are the passenger's really going to wait/care for the Captain's approval ?
