Weather Radar System helps pilots avoid hail and lightning.

Press Release Summary:

Aug 20, 2012 - To help optimize pilot's in-flight situational awareness and decision-making, IntuVue 3-D Weather Radar can detect turbulence, hail, and lightning, up to 10 minutes in advance of approaching storm cells in flight path of aircraft. Long turbulence detection range at 60 nm enables pilots to reroute or initiate turbulence avoidance procedures. With REACT system, pilots receive visible alert on radar screen when radar signal is losing strength.

Major upgrade of Honeywell IntuVue 3-D Weather Radar helps increase pilot in-flight situational awareness and improves decision-making around adverse weather

PHOENIX, -- Honeywell (NYSE:HON) has unveiled the latest updates to its IntuVue 3-D Weather Radar, which include new capabilities to detect turbulence, hail and lightning, up to 10 minutes in advance of approaching storm cells in the flight path of the aircraft.

Previously, pilots could not readily anticipate which storms in their flight path had either hail or lightning, or which storms contained turbulence at a long range. With this upgrade, flight crews are now better equipped to avoid hail, lightning, turbulence and other severe weather to keep flights on time, passengers safe and comfortable, and avoid potential aircraft damage.

According to the FAA, inclement weather accounts for almost 70 percent of all aircraft delays(1) and cost the U.S. economy alone more than $18 billion in 2008(2). Turbulence-related incidents cost airlines, on average, approximately $200,000 per incident according to the Bureau of Transportation Statistics.

Benefits of the IntuVue Upgrade
The latest version of the IntuVue 3-D weather radar builds on a history of providing pilots with accurate weather information. This upgrade helps pilots predict the probability of hail or lightning in storm cells, enabling enough time to make a safe flight path correction if required. In addition:

-- The predictive hail and lightning system uses complex algorithms that analyze data captured from constant scanning by the radar from ground level to 60,000 feet and out to 320 nautical miles (nm). Weather is also shown in a unique color pattern (red for most severe, yellow for moderately severe, green for less severe, magenta for turbulence) on a display screen, allowing a pilot to know more precisely what is around the aircraft.
-- After running the captured data through the new algorithms, the radar can identify storm cells that have the characteristics of hail and lightning and display a hail or lightning icon on top of the respective storm, giving pilots a clear idea of where the severe weather is in relation to the plane.
-- Also new is the industry's longest turbulence detection range at 60 nm, affording pilots more time to reroute or initiate turbulence avoidance procedures. Due to its unique design, the IntuVue lowers cost of operation through increased reliability of aircraft, lower fuel costs by smart flight paths and reduced maintenance cost by avoiding storms that could damage a plane.
-- Honeywell's new REACT system gives pilots a visible alert on the radar screen when the radar signal is losing strength. The alert shows pilots how far out from the aircraft the radar is losing strength and at what direction, so pilots have a better understanding of where potential storms could exist beyond radar's reach.

The IntuVue 3-D Weather Radar is available on a wide range of commercial, business and military applications. IntuVue has already received its first FAA Supplemental Type Certification (STC) approval and is the first and only radar certified to the FAA's new enhanced Minimum Operational Performance Standard (MOPS).

-- The new upgrade will initially be offered to customers as a retrofit option on Boeing 737-NG aircraft.
-- Honeywell is working with OEMs on further international certifications and forward-fit options for all platforms certified to use the IntuVue 3-D radar system, which include the B777, B737, A320, A330, A340, A350, A380 and Gulfstream G650 aircraft.

-- John Bolton, President Air Transport & Regional, Honeywell Aerospace
"Until now, aircraft damage and unstable flights resulting from hail and lightning were problems airlines and passengers had to accept. This new radar upgrade empowers pilots to avoid storm cells that have the potential to produce hail and lightning, spot turbulence earlier, and identify the precise location of heavy rain clouds to maximize passenger comfort and safety."

-- Dr. Ratan Khatwa, Senior Chief Engineer -- Human Factors, Honeywell Aerospace
"The IntuVue was designed from the ground up to provide pilots with superior information about the location of true weather threats, such as hail and lightning, relative to their aircraft. The much simplified weather information and radar operation results in reduced pilot workload levels compared to other radar systems, thus allowing the flight crew to focus on flying the aircraft safely."
