Aircraft
After takeoff; and just after gear retraction; we experienced a loss of the A system hydraulic pressure and quantity. We climbed to a safe altitude and notified ATC. We ran the appropriate checklist for the loss of A hydraulics. We requested delay vectors to complete the checklist. We briefed the passengers; and diverted to ZZZ. ATC advised that ZZZ was the longest runway nearby. We informed them that we would be stopping on the runway using emergency brakes. We were vectored to a right downwind for Runway XX by ATC. On the first attempt of landing; we were turned in too soon; resulting in an unstabilized approach. We executed a missed approach; and entered right traffic pattern as directed by ATC. On the second attempt; the landing was stabilized and completed with the use of emergency brakes. We stopped on the runway and were met by fire personnel. They gave us the all clear sign. We had the FBO come and grab the passengers to take them to the FBO. They then towed us into their ramp.
