Turnaround time is the ground time an aircraft needs between landing and its next takeoff. Even a "quick turn" has a fixed choreography: taxi in, shut down, deplane, refuel, service the lavatory, load catering and bags, file and brief the next leg, board, start, taxi out. On a light or midsize jet with everything pre-arranged and the fuel truck waiting, that compresses to about 30–45 minutes; a realistic planning figure at an unfamiliar or busy FBO is 45–60 minutes, and a heavy jet taking a large fuel load, or any aircraft on a snowy ramp waiting for de-icing, can need 90 minutes or more.
The variables are mundane but stack up. Fueling dominates — a super-midsize uplifting 1,200 gallons is a 25–40 minute pump job that usually cannot happen with passengers boarding, and at a busy field the truck itself may queue. International arrivals add customs clearance. Slot-controlled airports add the wait for the next available departure window. And the crew's own requirements ride along: the turnaround is working time inside their 14-hour duty day, so a multi-stop itinerary with four 45-minute turns spends three hours of the crew's legal clock on the ground.
For the customer, turnaround time matters most in two situations. Multi-stop days: a "quick meeting in three cities" itinerary should budget an honest hour per intermediate stop — planned at 20 minutes, it will run late by noon and collide with crew duty limits by evening. Waiting trips: if the aircraft drops you for a two-hour meeting and flies you home, the turnaround is baked into the day gracefully; but if your meeting stretches, remember the aircraft may have been resequenced behind other traffic for fuel or ramp space, so the departure doesn't always move minute-for-minute with you. Communicating delays early through the operator keeps the choreography intact — the crew can re-time fuel, slots, and catering around real information.
One useful distinction: turnaround for you (same aircraft, same passengers, continuing) is fast, because the crew keeps everything warm. Turnaround between charters — your flight ending and another customer's beginning — is slower, since cleaning, catering swap, and often a crew change intervene; operators typically plan 1.5–3 hours between unrelated trips. That gap is why a jet landing inbound at 3:00 p.m. isn't automatically available for your 3:30 departure even though it is sitting in view on the ramp, and why same-day recovery from earlier delays ripples the way it does. When timing is tight, the operator's dispatcher — reachable directly via the contacts on any Yond aircraft listing — can tell you what the realistic turn is for that tail, that airport, that day.
