Anomaly detection including system leaks and probe damage. Probe covers, insect habitation, ice, probe/port damage are easily discovered and reported as a source of bad air data. Single full time driven sensor for ease of integration into air data equipment. Can be utilised in air, ground, sea and industrial applications where fluid flow measurements are mission critical. The core sensor ideology may be implemented in gas, liquid and solid materials making it ideal for 'on the go' non-destructive testing. ABOUT -------------------------------------------------------------------------------- While developing the system we have always had in mind that we want to alleviate confusion on the flight deck by presenting clear information that when air speed indication is not correct on one or more air speed indicator (ASI), the pilot can know the moment it is happening and focus on either a good ASI, or refer to the aircraft manual on correct procedures for loss of air speed indication, saving valuable time. Bad air data and the confusion that can arise when pilots and/or automated systems are presented with information not known to be false, can start a chain of events which may threaten the safety of the aircraft. Pitot Guardian® technology incorporates our robust IP and know how and is designed to be embedded within next generation air data computers where it continuously monitors the architecture of the Pitot probe and static port, with various other configuration options such as 'in line' for aftermarket installation to pneumatic systems. It also has the capacity to become an integrated component of the Pitot probe and static port itself. With our anomaly sensing technology 'on-board', crucial and timely information concerning the state of the aircrafts' vital air data components can be presented to the flight crew saving valuable time in the event of an unreliable air speed situation. Potential cost savings over and above the obvious include; avoidance of aborted take off situations and expedited service time of the Pitot Static system where self test can be included in the sensor software. The devices have been tested in simulated flight conditions including wind tunnel and extreme vibration analysis, where they continue to operate and report as designed. Capabilities include (but not limited to); High speed in flight and ground detection of port / probe blockage before start up, early warning of impending full blockage, port covers attached, Insect Habitation such as keyhole wasp, Pitot Icing (high altitude and flash), Volcanic ash ingress and erosion or other types of probe damage likely to present false air speed data. Shortly after the loss of Air France flight 447 in June 2009 we set about developing a robust means of detecting anomalies in Pitot static systems which give rise to false air speed data being presented to pilots. Looking into existing efforts in this field it was decided that not enough was being done to address the issue, and some attempts were looking at over-complicated or impractical solutions. By late 2009 a broad patent was filed while working 'proof of principle' prototypes were being put together. During 2013 we began liaising with the aerospace industry on how best to proceed and we've been working hard building more and more robust devices all the while shrinking the required hardware and further developing our unique operating software to where it is today. Our sensor technology also has a place in mission critical industrial applications where the effectiveness of fluid flow measurement devices in a process is vital. Licensing options available upon request. RECENT -------------------------------------------------------------------------------- Between 9th June 2021 and 19th July 2021, several aircraft at London Heathrow Airport (LHR) were affected by abnormal pitot/static events, two of which resulted in rejected takeoffs. It was discovered later that in all cases, various Pitot tubes were blocked by insect activity. The AAIB Bulletin of March 2022 lists this as a 'Serious Incident'. Airbus A320-232, G-EUUO Airbus A320-251N, G-TTNH Boeing 777-236. G-YMMR Airbus A330-343, G-VKSS Boeing 787-9, G-ZBKJ Boeing 777-336ER, G-STBJ Boeing 787-8, G-ZBJF Airbus A319-131, G-DBCG PAST RELATED INCIDENTS -------------------------------------------------------------------------------- Aircraft incidents where unreliable airspeed has been a contributing factor; (This is not a comprehensive list) 1st December 1974: Northwest Airlines Flight 6231. Boeing 727 Pitot probes succumbed to atmospheric icing, subsequent loss of reliable air speed data caused the flight crew to lose control and crashed North West of JFK international airport. 6th February 1996: Birgenair Flight 301 crashed into the sea shortly after take-off due to unreliable air speed indication. The suspected cause was Mud-Dawber wasp infestation of one of the Pitot probes. 2nd October 1996: Aeroperu Flight 603 crashed due to unreliable air speed / altitude data having been caused by masking tape covering the ports. This should have been removed after the aircraft was cleaned and waxed. 12th May 2005: A Midwest Boeing 717-200 suffered temporary loss of control after the crew responded incorrectly to ice build up on the Pitot probes. 19th March 2006: A Qantas Airbus A300-303 Pilot in command rejected take off after a significant discrepancy was noticed between airspeed indicators. The heavy braking and heat build up caused the tyres' fuse plugs to blow out. 23rd February 2008: B2 Spirit Bomber crashed in Guam after moisture build up on three of the 24 air pressure sensors caused inaccurate data to reach the flight computer. The flight crew believed they were rotating at the correct speed of 140knts when in fact the speed was 10knts slower. The data also caused incorrect pitch information. The aircraft stalled and veered to the left. 28th January 2009: A Boeing B752 Astraeus Airlines being operated for Ghana Airways en-route Northern Ghana suffered temporary loss of control being caused by uncertainty regarding the presented air speed. A discrepancy was noticed during the take off roll but the pilot in command decided to continue and deal with the situation later on. 1st June 2009: Air France Flight AF447 Airbus A330 from Rio de Janeiro to Paris exited controlled flight and crashed into the sea. This was attributed to the inappropriate response by flight crew to the transient loss off airspeed indications in the cruise caused by high altitude ice crystals blocking the Pitot probes. 20th April 2012: Airbus A321-231 Registration G-EUXM encountered atmospheric conditions on two occasions which resulted in temporary loss of reliable air speed data. A PAN Was declared and the aircraft diverted to Stansted for an uneventful landing. While during the events it was not known what was causing the erroneous data due to additional problems being presented to flight crew and the distraction of a bright flash due to electrical discharge phenomena. Pitot icing, it was concluded, was the likely cause of the problems. 21st November 2013: Etihad A330-200 Flight EY473 Brisbane to Singapore. The pilot in command rejected take off due to airspeed discrepancy. After some troubleshooting back at the gate, another take off was attempted. A discrepancy was once again noted after V1 decision speed, the aircraft rotated and shortly after issued a Mayday. The aircraft returned to Brisbane for an overweight landing. The captains Pitot probe was later found to have been totally blocked by Mud-Dawber wasp activity occurring in just a two hour turn around period. 12th February 2018: Antonov AN-148-100B operated by Saratov Airlines had departed Moscow's Domodedovo airport en-route to Orsk when it crashed. It is reported, but yet to be confirmed, the Pitot heat had not been switched on as part of the take off check list. The Pitot probes were likely to have been iced up with a loss of reliable air speed information. (The following three incidents all took place on the same morning and are thought to be all attributed to heavy icing and pitot blockage) 26th February 2018 : Airbus A321-200 Registration HA-LXD Unreliable air speed indication while climbing out of Sofia, PAN Declared. Returned to Sofia. 26th February 2018 : Airbus A321-200 Registration HA-LXL Rejected take off from Sofia at 80 knots due to unreliable air speed indication. The aircraft slowed safely and returned to the apron. 26th February 2018: Airbus A321-200 Registration HA-LXP While climbing out of sofia the crew requested stop climb at 10,000 feet MSL, Climbed on to 12,000 due terrain, subsequently declared PAN,PAN,PAN emergency; reporting unreliable airspeed. Diverted to Budapest for a safe landing. 20th July 2018: Malaysia Flight MH134 Airbus A330-300 was released with all three Pitot covers left in place. After take off, the aircraft safely returned to Brisbane having declared a Pan Pan Pan emergency. 9th January 2019: UNMANNED vehicle ScanEagle X200 performing aerial work in the Woleebee Creek area of Queensland collided with terrain after a number of attempts to regain control by the ground flying pilots. Unreliable air speed due to blockage in the Pitot Static static was found to be the cause. 22nd May 2020: Wizz Air Airbus A320-200 on a scheduled flight between Bucharest and Stockholm was forced to stop climbing at 3000ft as the aircraft had 'issues' with airspeed indications, the crew burned fuel to reduce landing weight and returned to Bucharest Otopeni Airport. 16th June 2020: Wizz Air – Airbus A321 departing Doncaster Sheffield Airport after LONG STORAGE. The crew rejected take off and returned to the apron. The AAIB rated this as a Serious Incident and opened an investigation. 4th October 2020: TUI Boeing 737-800 flight number OR-695 from Amsterdam to Funchal with 189 people on board was at FL360 over the English Channel, crew made the decision to return to Amsterdam having reported unreliable airspeed, the cause is not yet known. 10th October 2020: A Lufthansa Cargo Boeing 777-200 freighter, registration D-ALFG performing flight GEC-8402 from Frankfurt/Main (Germany) to Shanghai Pudong (China), was in the initial climb out of Frankfurt's runway 25C when the crew declared Mayday reporting unreliable airspeed.
