Daltonomous - Dependable Global Navigation’s Post

Now things are getting scary. What was once thought to be a distant threat in conflict zones is now rearing its head close to home. This invisible problem is already causing hundreds of millions of dollars of economic impact - and that's not even the full threat landscape that comes from nefarious electromagnetic interference. Solving this is a priority. It's what we are focused on right now. #GPS #Resiliency #defense #aerospace #priority

Question 1 is addressing SpaceX normal work Question 2 is addressing Federal Aviation Administration adaptation to reusable launch systems Question 3 is addressing International Civil Aviation Organization that as already started to think about better integration of #AirTrafficManagement and #SpaceTrafficManagement under the pressure of EASA - European Union Aviation Safety Agency, European Space Agency - ESA, European national space agencies and International Telecommunication Union

MANY THINGS TO EXPLAIN ABOUT THE STARSHIP MISHAP "The FAA also confirmed in its statement that debris from the incident fell outside of designated areas. “During the event, the FAA activated a Debris Response Area and briefly slowed aircraft outside the area where space vehicle debris was falling or stopped aircraft at their departure location. Several aircraft requested to divert due to low fuel levels while holding outside impacted areas,” the agency stated. “A Debris Response Area is activated only if the space vehicle experiences an anomaly with debris falling outside of the identified closed aircraft hazard areas,” the FAA added. “It allows the FAA to direct aircraft to exit the area and prevent others from entering.” Things to explain: 1) Why did the Autonomous Flight Termination System (AFTS) (apparently) fail to trigger the controlled explosion of Starship? 2) Why do launch regulations not include extra safety features for test launches vs. operational launches? 3) Why is ICAO not involved in the investigation of space mishaps of this kind impacting the international airspace under its jurisdiction?

How navigation safety can be enhanced by space weather forecasts Aircraft navigation is a complex process including satellite, reference, and management systems to determine position and guide planes to their destination. Despite the sophistication of Global Navigation Satellite Systems (GNSS), they remain error-prone. The Wide Area Augmentation System (WAAS) has been developed to enhance GPS performance, improving its accuracy, integrity, and availability for aviation needs. But what if it fails? The 2003 ‘Halloween Storms’ affected WAAS for nearly 30 hours. During the storms, the ionosphere was severely disturbed, causing the vertical error limit of WAAS to be exceeded. WAAS was unavailable for precision aircraft approaches, as it could not meet the accuracy requirements. For a successful flight in such conditions, a pilot would need higher visibility, more conservative fuel planning in case of diversions, and ground-based navigation aids like Instrument Landing Systems (ILS). Passengers may experience delays, cancellations, or diversions due to the reduced approach capabilities at airports relying on WAAS. While ILS is a widely used system, it is not universally installed at every airport. Smaller, lower-traffic facilities may not have ILS, as the infrastructure can be too costly for them. The other reason for the lack of ILS is the challenging terrain. An airport may be unable to meet the siting requirements for a full ILS installation. I think that the more we rely on satellite data and systems like GNSS/GPS, the more we need to enhance our space-weather infrastructure and implement widespread, accessible alert systems 📢 The safety of passenger, cargo, and noncommercial flights depends on a comprehensive plan to safeguard satellite-based navigation 🧭 #spaceweather #spacetech #aviation #GPS #space

How Pilots Navigate in Bad Weather: Mastering the Skies with Precision and Skill 🌧️✈️ Ever wonder how pilots handle those turbulent skies and stormy clouds? Navigating through bad weather is no easy task—it’s a blend of advanced technology, in-depth training, and an unwavering focus on passenger safety. When faced with challenging weather conditions, pilots rely on various navigation tools, including radar systems, satellite-based GPS, and onboard instruments to monitor changing conditions in real-time. They coordinate closely with Air Traffic Control (ATC) to adjust routes, altitude, and speed, ensuring the smoothest and safest flight path possible. The key to safe navigation in adverse weather lies in constant situational awareness, adaptability, and thorough pre-flight planning. Every pilot reviews weather forecasts, uses sophisticated flight management systems, and is trained to make split-second decisions that keep everyone on board safe. Pilots’ expertise, combined with cutting-edge aviation technology, allows them to stay calm and confident even when Mother Nature throws in a twist. It’s the art and science of flying at its best! 🔗 #Aviation #PilotSkills #WeatherNavigation #AviationSafety #FlightPlanning #Aerospace #AviationTech

"North Carolina is investing in its position in the rapidly evolving drone and Urban Air Mobility sector. . . The program’s scope extends beyond purely technical aspects, encompassing emergency response capabilities, regional air mobility solutions, and the development of essential infrastructure and workforce training programs." The integrated approach to this funding and the program is encouraging. In addition to essential infrastructure, it would be good to see a focus on airspace management and the airspace component of the ecosystem. https://lnkd.in/g3Nng4PH #evtol #bvlos

Understanding NOTAMs✈️ A NOTAM (Notice to Airmen or Notice to Air Missions) is a critical communication tool in aviation, distributed via telecommunications, that provides essential, time-sensitive information to flight crews, air traffic controllers, and other personnel involved in flight operations. It informs them about changes or updates to installations, services, procedures, or any potential hazards in the air or on the ground that could affect flight safety. Let’s break down the key parts of a NOTAM and what they mean: 1. Header: Serial Number: A unique identifier for each NOTAM. Type of NOTAM: It specifies whether the NOTAM is new 👎, a cancellation (C), or a replacement (R). Location: The ICAO code of the location associated with the NOTAM. 2. Text (Body): Q Line: This is the rating line, providing a detailed classification of the NOTAM, including location, condition, and type of restriction. Location Code: The FIR (Flight Information Region) where the NOTAM applies. Classification: Describes the type of information such as airspace restrictions, obstacles, or dangers. Condition: Details the nature of the restriction (e.g., closed runway, airspace change). Restriction Type: Indicates if it's a new restriction, modification, or cancellation. Altitude: Specifies the range of altitudes affected by the NOTAM. Airspace: Defines which portion of airspace is impacted. A Line: Specifies the airport or location directly affected. B Line: Indicates the start time of the NOTAM (format: YYMMDDHHMM). C Line: Indicates the end time of the NOTAM (format: YYMMDDHHMM). D Line: If applicable, specifies operational times if the restriction isn’t continuous. E Line: A free-text section offering more specific details about the restriction or condition. NOTAM Example: (A1234/23 NOTAMN Q) LECB/QFALT/IV/NBO/A/000/999/4120N00205E005 A) LEBL B) 2306250600 C) 2306251800 E) RWY 07L/25R CLSD DUE TO MAINTENANCE) Breaking Down the Example: A1234/23: The unique serial number for this NOTAM. NOTAMN: Indicates it's a new NOTAM. Q Line (LECB/QFALT/IV/NBO/A/000/999/4120N00205E005): LECB: The FIR, in this case, Barcelona. QFALT: Describes the classification, indicating a runway alteration. IV: Traffic classification (applicable to both VFR and IFR). NBO: Condition code, which provides more details on the situation. A: The restriction applies to an aerodrome. 000/999: Altitude affected (from ground level to FL999). 4120N00205E005: The geographic coordinates of the affected area. A) LEBL: Refers to Barcelona Airport. B) 2306250600: Start time (June 25, 2023, at 06:00 UTC). C) 2306251800: End time (June 25, 2023, at 18:00 UTC). E) RWY 07L/25R CLSD DUE TO MAINTENANCE: Free text specifying the runway closure due to maintenance. Why NOTAMs Matter NOTAMs are crucial because they communicate vital safety information quickly and efficiently, allowing flight crews and air traffic controllers to adapt operations accordingly.
