PETALING JAYA: When it was first speculated that Flight MH370 could have been hijacked via remote control access, many dismissed it as far-fetched science fiction.
But the technology to navigate planes, ships, trains, buses and other vehicles by remote control has been around for about a decade.
The Boeing Company, the world’s leading aerospace company and the largest manufacturer of commercial jetliners and military aircraft, has the technology.
It owns a patent for a system that enables remote controlling of its aircraft to counter hijacking attempts.
Boeing applied for the patent for an “uninterruptible autopilot control system” about 11 years ago, and was awarded it in 2006.
The system can be activated when the security of onboard controls are jeopardised.
“The method and systems of the present invention provide techniques for automatically navigating, flying and landing an air vehicle,” states the report for the US patent number US7142971B2.
Once activated, an aircraft could be automatically navigated, flown and made to land without input from anyone on board.
“Any onboard capability to supercede the automatic control system may be disabled by disconnecting the onboard controls,” states the report.
Power is provided to the automatic control system “from an alternative power control element that is inaccessible (to anyone on board the vehicle)”.
According to the patent report, control commands could be received from a remote location and/or from predetermined control commands stored on board the plane.
Boeing applied for the patent on Feb 19, 2003, barely two years after the Sept 11 attack in which hijacked planes rammed into the World Trade Centre, reducing the gigantic buildings into rubble.
Eric D. Brown, Douglas C. Cameron, Krish R. Krothapalli, Walter von Klein Jr and Todd M. William invented the system for Boeing. The patent was awarded three years later on Nov 28, 2006.
When the automatic control system is activated, no one on board the aircraft would be capable of controlling its flight.
The patent report also states that a signal might be transmitted to at least one remote location from the plane to indicate that the uninterruptible autopilot mode of the air vehicle has been engaged.
The system includes a dedicated communication link between the aircraft and a remote location, distinct from any communication link established for other types of communication.
According to an independent analyst James Corbett, the US Federal Aviation Administration had reported on the Federal Registrar last November that the Boeing 777-200, -300 and –300ER aircraft were equipped with an electronics security system to check unauthorised internal access.
