Horizon Aircraft signed a letter of intent on 29 September with Ontario-based Great Lakes Helicopter covering pilot training, MRO services and a tentative order for the Canadian developer's hybrid-electric Cavorite X7 vertical take-off and landing aircraft — with certification and revenue service no earlier than the early 2030s.

The LOI commits Great Lakes to "facilitate pilot training programmes to support future X7 operators" and to provide MRO support for the X7 once it enters service. It also documents a non-binding commitment for an undisclosed number of airframes, leaving the orderbook headline open-ended.

What will X7 pilot training actually look like?

Horizon says the syllabus "will be very traditional in nature" and remains under development.

"It will involve initial computer-based training that will include all systems, followed by a comprehensive computer program that works from [conventional take-off and landing] back into transition and VTOL flight regimes," the company tells FlightGlobal.

"From there, a traditional type-rating programme will follow, with focus on VTOL and transition flight regimes, tailored of course to the type of underpinning commercial flight licence, fixed- or rotary-wing, the owner possesses."

The structure mirrors a conventional rotorcraft or regional type-rating — CBT, a device-based phase, then a check ride — but layers in transition flight, the segment that separates VTOL aircraft operating in both conventional and vertical modes from helicopters or fixed-wing platforms.

Tailoring the syllabus to the pilot's existing licence keeps the conversion path short for both helicopter and fixed-wing operators — a useful commercial lever for a type aimed at two distinct customer pools.

Why a helicopter operator as training anchor?

Great Lakes Helicopter is an Ontario-based operator working in the regional and utility segment Horizon has identified as the X7's natural early customer base. Chief executive Brandon Robinson calls the deal a vital step to "build the ecosystem needed to support the Cavorite X7 and its future customers".

For an early-stage VTOL programme, locking in a training and MRO partner answers two procurement questions that drive orderbook conversion: where pilots will be trained, and who keeps the airframe airworthy once revenue flying starts.

The same line of work also gives Great Lakes a foothold in hybrid-electric VTOL operations without committing to a large firm order at the prototype stage.

How far is the programme from flight?

No Cavorite X7 has flown publicly. Certification and revenue service remain targeted for the early 2030s, leaving several years between today's LOI and the first paying flight.

The LOI itself is non-binding, and the airframe count is undisclosed — the kind of paperwork that builds backlog headlines without committing either side to payments or deliveries until a definitive contract is signed.

For Horizon, that gap matters: an LOI is not a deposit, a delivery slot or a training invoice.

What does this change today?

In commercial terms, very little. A letter of intent does not move metal, generate training revenue or commit Great Lakes to a purchase. It does, however, give Horizon a tangible answer to a routine customer question before a prototype has flown.

The next verifiable milestones will be a first flight of the X7 prototype and a published certification basis — both of which Horizon has yet to detail publicly. Until those land, Great Lakes' role remains a roadmap entry rather than a binding contract.

If Horizon holds the early-2030s service entry target, the operator's training and MRO capability will need to mature alongside a programme that today exists only as computer-based training outlines and a non-binding letter of intent.
