The aircraft deploys a refueling probe to couple with the FA-18 fighters for simulated refueling.
The KC-135 operates on the same track as other aircraft. Using the B key or Action Trigger setting 10, the tanker lifts above the track by 7 metres and deploys the probe.
The FA-18 approaches from the rear and couples with the probe at its own refueling probe. A second trigger further along the track retracts the probe, and after you decouple the FA-18, they operate separately again.
