The pilot shall notify his Chief Pilot in writing of the election under this paragraph, which shall include:

a. The selection by the pilot of a non-FDA crew position that a junior pilot is activated in and currently holds; and

b. The pilot’s preferred exit date (i.e., the date upon which the pilot starts ITU training or when the pilot base transfers), which shall not be less than 6 months from the date of the notice. The preferred exit date must be after the completion of the pilot’s commitment period, plus 12 months.

The above deals with HKG or any other FDA that doesn't have a maximum time limit. I believe that if you're in CGN you're stuck until there's a bid or you hit that maximum limit.
