Sullivan, INICAO KSIV · FAA SIV

If things change. Want flight following after departure? Call Hulman Approach on 135.35 once clear of the pattern: identification, type, position, altitude, destination, "request VFR flight following" (AIM 4-1-18 a 3). Do not use "any traffic in the area, please advise"; the AIM says it is not to be used under any condition (AIM 4-1-9 g 1).
