Dubai’s ruling family is set to acquire a series of aerospace and defence businesses across the US which will test the country’s readiness to entertain Arab owners of infrastructure assets in a deal which could be valued at more than $1.5bn.

Dubai Aerospace Enterprise, which aims to create a $15bn aerospace and aviation services company, is in advanced talks with Carlyle, the private equity firm, about acquiring part of Landmark Aviation and Standard Aero, which both provide engine repair and overhaul aviation services.
