lieved from duty to return to his home

period. 

(g) A flight crewmember is not con-

sidered to be scheduled for flight time 
in excess of flight time limitations if 
the flights to which he is assigned are 
scheduled and normally terminate 
within the limitations, but due to cir-
cumstances beyond the control of the 
certificate holder (such as adverse 
weather conditions), are not at the 
time of departure expected to reach 
their destination within the scheduled 
time.
