RVSM Heats Up

Honeywell and West Star Aviation have received Federal Aviation Administration (FAA) certification of a system enabling Learjet 35/36 series aircraft to meet the fast-approaching deadline for reduced vertical separation minimum (RVSM) capability. The RVSM package includes Honeywell’s AZ-252 advanced air data computer, AM-250 barometric altimeter/air data computer, BA-250 altimeter display and AL-800 attitude alerter control, as well as an Aerosonic standby altimeter and Rosemount pitot-static probes. West Star already has completed and delivered its first RVSM-certified Learjet.

Jet Aviation Dallas, an authorized Citation service center, also has completed four RVSM installations, including a 525, a 501 and two 560 Citation jets. All four modifications replaced existing air data computers and altimeters, and the majority of the RVSM work required preparing the aircraft skin for smooth air flow by the static ports.

BAE Systems’ Next-Gen RTOS

BAE Systems has unveiled a new version of its CsLEOS real-time operating system (RTOS)–certifiable to DO-178B, Level A–with integrated fault-tolerant and "hard" real-time features. BAE claims that CsLEOS is the first commercial RTOS "built from the ground up" with a native ARINC 653 interface. (The ARINC 653 standard defines partitions between applications, allowing applications with different levels of criticality to coexist on the same hardware.)

Though CsLEOS is a relative newcomer in the RTOS market–development started three years ago–the product is the first commercial, off-the-shelf, ARINC-653 RTOS to fly on flight-critical hardware, BAE says. CsLEOS "underpins" the integrated vehicle management system computer on the Pegasus X-47A unmanned combat aircraft, developed by Northrop Grumman for the U.S. Navy. The product also will be used on a new flight control computer for the C-17 transport aircraft.

The new version of the RTOS supports independently loadable applications and provides native support for OpenGL graphics, allowing secure two- and three-dimensional displays to run on the same processor alongside safety-critical applications. Visit

UAV Wins ‘National’ NAS Approval

The U.S. Air Force has received a national certificate of authorization (COA) from the Federal Aviation Administration (FAA). The COA will simplify the coordination process required to fly the high-altitude, long-endurance Global Hawk reconnaissance unmanned air vehicle (UAV) in the National Airspace System (NAS). To the Air Force the COA is a step along the way to achieving "routine" airspace access.

The Global Hawk–a UAV with a wingspan almost as large as a Boeing 737–became a household name, flying missions in operations Iraqi Freedom and Enduring Freedom. The UAV has flown more than 3,000 hours since its first flight in February 1998.

FAA consolidated all the existing Global Hawk COAs–issued for flying in different areas of the United States–into one document, says an agency official. The Air Force still has to brief FAA on the flight plan and emergency and contingency plans before takeoff, but processing and approval timelines will shrink from 60 to as few as five days. The new COA is for flight operations only, an FAA spokesman told our sister publication, Defense Daily, and such approvals will continue to be scrutinized on a case-by-case basis. The military has essentially vouched for the UAV’s airworthiness.

The Defense Department (DoD) is responsible for traffic "deconfliction" with other government assets above altitudes of around 60,000 feet. "Below that, we are on a flight plan, like any aircraft, but must provide a means to assure traffic safety," according to Global Hawk program officials. The streamlined coordination procedures, however, still "limit the long-term flexibility the Air Force requires to execute its mission." The service wants "file and fly" access to U.S. and international airspace.

Under the COA, Global Hawk officials must specify to FAA how it will provide a measure of safety equivalent to that of manned aircraft. FAA Order 7610.4, regarding special military operations, states various means by which this "equivalent level of safety" may be declared, including radar observation, electronic detection systems (such as cameras), visual observation from one or more ground sites, monitoring by patrol or chase aircraft, or a combination of these. Radar observation means using an external radar–provided by a command and control aircraft, by FAA/military surface radar, or even by an airborne escort–to clear the UAV flight path. Coordinating days in advance and taking a variety of these measures to assure safety mean Global Hawk access is still far from routine.

A big part of the plan to assure traffic safety in the future will be adding "see-and-avoid" sensors, which will enable a UAV "pilot" to detect traffic and act to avoid a collision. According to program officials, "An onboard see-and-avoid capability is required to achieve total global access to airspace." The Air Force is developing prospective technologies for implementation, beginning in FY 2008. Although there are individual sensors that may support a solution, a package integrated so as to operate in the UAV environment, and with the size, weight and power constraints of UAVS, does not yet exist.

The RQ-4 Global Hawk features such elements as a fully redundant flight control avionics architecture and air traffic control radios and data links. Global Hawk also can file instrument flight rules (IFR) flight plans. The Air Force is testing the use of Mode-S transponders, which will assist the UAV pilot, air traffic controllers and other aircraft. Northrop Grumman is working on a nose-mounted camera for monitoring what is in front of the UAV during takeoffs and landings, according to Defense Daily. This work eventually could lead to see-and-avoid capability. Under current Air Force contracts, the company also is developing a threat collision avoidance system.

The Air Force is making "many changes" in the production UAV system to assure it meets the same functional standards as manned aircraft, the Global Hawk program office says. This will include refinements to the navigation suite, communications systems and ground station. The traffic alert collision avoidance system (TCAS) "is under study, but [TCAS] is not approved for use on UAVs," officials say. Indeed, Global Hawk "will not be permitted to respond to TCAS alerts without specific ATC direction," they add. The Air Force also expects to implement the navigation and communications standards of the global air traffic management (GATM) program in the vehicles to be delivered in fiscal year 2006.
