Raas System Aircraft - ROAAS does not guarantee successful recovery from a pending runway overrun due to variability in factors such as pilot response, actual aircraft performance, and actual runway length and condition. Moreover, ROAAS may not be available at all runways worldwide, depending on database inclusion.
Germany's Lufthansa becomes the seventh airline to buy the system, after companies including Air France-KLM, United Airlines, Alaska Airlines and FedEx, according to Honeywell spokesman Bill Reavis. Reavis said that under its agreement with Lufthansa, Honeywell may not disclose financial terms of the contract.

And business jet pilots aren't immune either! Your passengers' most popular destinations have the most stressful landing and takeoff conditions. Rifle Garfield County Airport in Colorado, and Bert Mooney Airport in Butte, Montana, have challenges like high density altitude, short runways, box canyons, limited airspace with dense traffic, and extreme weather conditions – a nasty combination.
Precautions For Use
White knuckles for sure. Honeywell's aerospace division, based in Phoenix, said installation of the safety equipment, called the Runway Awareness and Advisory System, should begin during the second quarter of this year. The system is designed to prevent runway incursions and accidents by alerting cockpit crews about runway distances, the presence of other aircraft or other potential problems.
Runway overruns upon landing are largely considered as one of the greatest operational risks in commercial air transport and to date they are still a major contributor to accidents. Over the last 10 years, significant rulemaking efforts and industry activities have been committed to reduce runway excursions.
Airline pilots flying into popular destinations like New York, San Diego and Washington, D.C., often have difficult approaches because of their busy airspace. LaGuardia Airport is one of three airports around New York City, so pilots must negotiate multiple runways with many jets landing in quick succession.
San Diego International's busy and steep approach brings pilots right over the city skyline. And flying into Ronald Reagan Washington National Airport in Washington, D.C., requires navigating around several no-fly zones and executing a 30- to 40-degree turn close to the Potomac River to line up with the runway.
Roaas Operations
The system "will provide us with an extra margin of safety during ground operations," Claus Richter, vice president for operational support and deputy chief pilot for Lufthansa, said in a statement. The airline's formal name is Deutsche Lufthansa AG.
The result is an intuitive, graphical display that provides real-time indications of contextualised, energy-based aircraft stopping points, accompanied by timely alerts if a pilot response is required. Systems that provide flight crew alerting of an impending runway overrun have previously been developed on other airplanes.
The next evolution of Honeywell's Runway Awareness and Advisory System - RAAS, SmartRunway and SmartLanding are software options for the Enhanced Ground Proximity Warning System (EGPWS) which increase flight crew situational awareness during taxi, take-off and landing.
The RAAS system works by using global positioning technology to compare the aircraft's location with a database of airport runways to determine the plane's exact location on the airfield. The system can alert pilots when they enter a runway and provide audio alerts in situations such as landing or takeoff on a short runway, an inadvertent attempt to take off from a taxiway or an aborted takeoff or long landing, when it can call out remaining runway
distance. EUROCONTROL's European Action Plan for the Prevention of Runway Excursions of January 2013 states that “on-board real time performance monitoring and alerting systems that will assist the flight crew with the land/go-around decision and warn when more deceleration force is needed should be
made widely available". There are a number of commercial solutions available to address this need and Gulfstream and Honeywell have developed one solution, the runway overrun awareness and alerting system (ROAAS), which acts as a safety enhancement tool to flight crews during the approach and landing phases of flight
operations in order to prevent runway excursions. Other commercial offerings by Boeing and Airbus are discussed in separate articles. RAAS provides the flight crew with five 'routine advisories'. Three of these announcements will be heard by the crew in normal operations, providing increased position awareness relative to the runway during taxi and flight operations.
They are intended to reduce the risk of a runway incursion. The two remaining 'routine' advisories provide information about the aircraft location along the runway, and are intended to reduce the risk of overruns. The five advisories are:
ROAAS is not intended to be used as the sole landing or go-around decision making tool and does not substitute for landing distance assessments or normal flight management system (FMS) take-off and landing data (TOLD) calculations based on the airplane flight manual
(AFM) and operator specific standard operating procedures (SOP) for stabilized approach criteria. The pilots should be able to manually inhibit aural warnings in order to avoid false and/or nuisance warnings due to a faulty or incomplete database, MEL-items, local NOTAMs, etc.
The use of the ROAAS should be part of pilot initial and recurrent training. The ROAAS equipped aircraft operators should develop clear and unambiguous SOPs and callouts for ROAAS operations. In addition to the aural announcements provided, visual caution indications may be activated if the appropriate criteria are met.
Visual text announcements can also be configured so they are overlaid on the terrain display for a period of time after the warning is generated. The Runway Awareness and Advisory System (RAAS) is one of a number of related software enhancements available on later-model Enhanced Ground Proximity Warning Systems.
RAAS is designed to improve flight crew situational awareness, thereby reducing the risks of runway incursion, runway confusion and runway excursions. The pilot monitoring (PM) should use the ROAAS indications to provide succinct verbal approach updates to the pilot flying (PF) throughout the approach and landing (including roll-out).
These crew callouts include an initial callout when the display becomes visible (“ROAAS is green”, or “ROAAS is amber, etc.). ROAAS can be used in a wide variety of scenarios and approaches, while accurately alerting the crew of potential opportunities for runway overruns and allowing enough time for an appropriate preventive action to be taken.
The ROAAS display and corresponding aural alerts act as a tertiary source for determining if the aircraft would stop within the runway length and, if so, a stopping point within those limitations. Honeywell, with corporate headquarters in Morris Township, N.J., has about $26 billion in annual revenue from products in avionics, aircraft engines and other systems, engineered materials such as chemicals and fibers, automotive equipment and advanced materials.
The company is one of the 30 stocks in the Dow Jones Industrial Average. In addition, RAAS provides the flight crew with several 'non-routine' advisories/cautions. These announcements are designed to enhance safety and situational awareness in specific situations not routinely encountered during normal aircraft operations.
Some of the RAAS advisories include distance information. The unit of measure used for distance can be configured to be either meters or feet. An additional contributory factor to runway overruns has to do with the wrong or late decisions to adjust the aircraft energy state and/or configuration, and/or wrong or late decision to conduct a go-around or apply maximum deceleration.
Runway Awareness and Advisory System uses airport data stored in the EGPWS database, coupled with GPS and other onboard sensors, to monitor the movement of an aircraft around the airport. It provides visual/aural announcements at critical points, such as "Approaching Runway 09 Left and confirmation when an aircraft is lined up on the runway prior to takeoff: for example, "On Runway 09 Right, 2,450 meters remaining." In a scenario where
a crew inadvertently lines up on a parallel taxiway and begins a take off, an aural alert "On Taxiway, On Taxiway" is provided if the aircraft speed exceeds 40 kts. On approach and after touchdown, the system continues to announce the distance to go
until the end of the runway is reached.
