Flight Crew Air Transport Pilot (ATP)
Situational Awareness
Deviation - Altitude Excursion From Assigned Altitude; Inflight Event / Encounter Wake Vortex Encounter
Air Traffic Control Issued New Clearance; Air Traffic Control Separated Traffic; Flight Crew Regained Aircraft Control; Flight Crew Requested ATC Assistance / Clarification; Flight Crew Took Evasive Action
Environment - Non Weather Related; Procedure
This is a wake turbulence encounter at FL428. It occurred 102 north of JENKS. We were at FL410 and had requested FL430 but ATC was waiting for aircraft above us at FL430 to pass overhead. ATC issued a climb once the aircraft passed over us and was 10 miles in front of us. We looked at our fuel and thought it was adequate so we asked to stay at FL410. We were told to go to FL430 or down to FL400 - so we chose the climb for fuel conservation. We had been battling a 65 kt headwind that just slightly quartered our right nose. We started a fairly slow climb and the air got 'burbly' at FL425. We then experienced a roll to the left and I disengaged the autopilot. Shortly after we got the snap to the right. We ended up going to FL428 before leveling off at FL430. We immediately inquired about the well-being of passengers - they were ok. The copilot offset the route by 2 miles right of course (west). Later we found out that [it] was an A350 that passed overhead.10 miles was probably not enough room for wake separation. I will offset before climbing and note headwind if it is directly ahead of you because vortices will sink straight down.
While climbing through FL425; we started experiencing mild wake turbulence from the aircraft ahead at FL430. Shortly thereafter; the aircraft abruptly rolled left and then right. We regained control of the aircraft at FL438. We descended immediately back to our assigned altitude of FL430. No injuries occurred to the passengers or crewmembers. I asked how much distance was between us and the traffic ahead. ATC advised there was 10 nm between us. I asked ATC for a 2 nm offset right of our course to prevent any further chances of flying into more wake turbulence. ATC asked if we were experiencing wake turbulence from the heavy Airbus 350. I replied that we were experiencing some wake turbulence. ATC approved to 2 nm offset to the right. We continued to our destination with further incident.ATC never advised the type of aircraft we were following during the climb. If ATC had advised we were climbing into the path of a heavy jet aircraft; we would have offset our course preventing us to encounter the wake turbulence during our climb to FL430.
EMB-505 flight crew reported encountering wake turbulence 10 miles in trail of an A350 at FL425.
