How to get FAA's streamlined Part 91.113 waiver for public safety UAS operations

How Pilots Avoid Mid-Air Collisions – TCAS in Action This diagram shows how the Traffic Collision Avoidance System (TCAS) works to keep aircraft safe in the skies. Caution Area (TA – Traffic Advisory, 20–48 sec) The system alerts pilots of nearby traffic so they’re aware early. Warning Area (RA – Resolution Advisory, 15–35 sec) If another aircraft gets too close, TCAS gives direct instructions like “Climb” or “Descend” to maintain safe separation. Collision Area If nothing is done, this is where two aircraft paths would intersect—something TCAS is designed to prevent. Fun fact: TCAS works independently of Air Traffic Control, providing pilots with a final safety net against mid-air collisions. Aviation safety is all about layers of protection—and TCAS is one of the most important.

✈️ Day 32: Aircraft Navigation Lights – Have You Noticed These Colours in the Sky? Ever looked up at an aircraft during dusk or night and spotted red, green, or white lights? These aren't just for show — they’re navigation lights, and they play a crucial role in aviation safety. 🔍 Let’s break it down: 🔴 Red Light – Mounted on the port side (left wingtip) 🟢 Green Light – Mounted on the starboard side (right wingtip) ⚪ White Light – Positioned at the tail (rear) ✅ From the rear, only the white light is visible. ✅ The red and green lights are visible from the front and sides, helping observers determine the aircraft’s direction and orientation. 🛫 Why are these lights important? Preventing Mid-Air Collisions – Helps other pilots identify aircraft heading and position. Night-Time Visibility – Ensures aircraft are visible to others in the sky and on the ground. Orientation Awareness – ATC and ground crew can instantly tell which way the aircraft is facing.

🛑 TCAS Protection Zones – Stay Alert, Stay Safe! Modern aircraft are equipped with TCAS (Traffic Collision Avoidance System) to prevent mid-air collisions by alerting pilots about nearby traffic. Let’s break down the 3 Safety Zones shown in this graphic: 🔵 1. Caution Area – TA (Traffic Advisory) 📍 Triggered 20–48 seconds before a potential conflict 👂 You’ll hear: “Traffic, Traffic” 🧠 Pilot should be aware of the traffic but no immediate action is required. 🟠 2. Warning Area – RA (Resolution Advisory) 📍 Triggered 15–35 seconds before conflict 🚨 You’ll hear: “Climb! Climb Now!” or “Descend!” 🧭 Immediate vertical manoeuvre required to avoid collision. 👨✈️ Follow the RA, even if ATC has given a conflicting clearance. 🔴 3. Collision Area ❌ This is the danger zone – too close for comfort! If you end up here, it’s already a near miss or worse. 🧠 Final Tip: RAs override ATC instructions. In case of conflict: 🚫 Ignore ATC, ✅ Obey the TCAS. 🧡 Safety begins with awareness!

The CAA has published a consultation on our proposed policy concept for Command and Control (C2) links used by Uncrewed Aircraft Systems (UAS) operating Beyond Visual Line of Sight (BVLOS). This document outlines some early proposals to support compliance with UK SORA and explores how existing telecoms and aviation standards could be applied to C2 link design and delivery. They are seeking feedback from UAS operators, equipment manufacturers, telecoms providers, and other stakeholders. You can read the consultation and share your views here: https://lnkd.in/eVC7cwrs

FAA published updated D.C. helicopter route charts to add separation and remove ambiguity after the January 29 midair collision. At DCA, Routes 1 and 5 remain for priority medical and law enforcement unless ATC authorizes otherwise, and Zones 1, 2, and 5 are reduced with clearer notes. BWI's Route 12 shifts north of I-95; IAD's Route 7 crossing altitude increases by 500 feet to protect go-around margins. Outcome: wider buffers between rotorcraft and fixed-wing traffic with minimal schedule impact. @FederalAviationAdministration #AviationSafety #DCA #AirTravel https://lnkd.in/gjYYwKaf

Mid-Air Collision Avoidance – How Modern Jets Stay Safely Apart One of the biggest fears people have when flying is the thought of two airplanes colliding mid-air. Thankfully, modern aviation has multiple layers of protection to make this incredibly rare. How it works, simply: Mid-air collision avoidance relies on strict air traffic control (ATC) rules and onboard systems. Pilots follow ATC instructions to stay on safe routes and maintain assigned altitudes. On top of that, jets have a Traffic Collision Avoidance System (TCAS) — a smart radar that scans for nearby aircraft and alerts pilots if another plane gets too close. TCAS can even issue automatic instructions to climb or descend to avoid a conflict. 🔹 Key points: 🔹 ATC separates aircraft using designated flight levels and routes. 🔹 TCAS is an independent last line of defense if human or radar errors occur. 🔹 Pilots are trained to respond instantly to TCAS alerts, even if it means ignoring ATC for a moment. ⭕️ Did you know? The introduction of TCAS in the 1980s drastically reduced mid-air collisions between commercial airliners. ✈️ Behind the scenes: Controllers use radar and satellite tracking to keep planes safely spaced — even across oceanic routes where radar coverage is sparse, pilots report positions regularly to maintain safe distances. 🗳️ Poll: What do you think is the most important factor for safe skies? * Air Traffic Control * Pilot training * Advanced onboard tech like TCAS * Good weather conditions

✈️ Understanding Marshalling Signals – The Language of Aircraft Ground Handling! 🦺 Ground marshalling is one of the most crucial aspects of safe aircraft movement on the apron. Communication between the pilot and ground crew happens through standardized hand signals, ensuring clear instructions even in noisy airport environments. This chart shows the most common marshalling signals, such as: 👋 Wing walker (Guide) – Guides the aircraft safely around obstacles. ➡️ Straight Ahead / Turn Left / Turn Right – Directs aircraft movement. 🛑 Normal Stop / Chocks Inserted – Indicates when to stop and secure the aircraft. 🌀 Start Engine / Cut Engine – Communicates engine operation status. 🐢 Slow Down – Reduces taxiing speed for safety. From the pilot’s perspective, signals like Brakes Engaged, Insert Chocks, Ready to Start Engine, and Remove Chocks help coordinate perfectly with the ground crew. Marshalling signals are a silent yet powerful language of aviation safety, ensuring precision, coordination, and protection for both crew and aircraft. #AviationSafety #AircraftMarshalling #GroundHandling #AviationKnowledge #AirportOperations #AviationEnthusiast #SafetyFirst #iPint

For years, if you wanted to fly beyond visual line of sight, you had to submit a waiver for each operation. Part 108 is the FAA’s Notice of Proposed Rulemaking (NPRM) that aims to change that. It creates a framework, a rulebook, for how companies could operate beyond the horizon. It is important to note: Part 108 is not final yet. The proposed rule is open for comment, and the details will likely shift before it becomes official. What will not change are the fundamentals. A light package delivery drone will never face the same requirements as a 100-pound system crossing state lines. Safety management systems, documentation, and uniform training will remain essential. Without them, companies cannot scale and they cannot stay compliant. At USI, we have spent more than a decade helping enterprises prepare for exactly this kind of shift. No matter how Part 108 evolves, we are ready to adapt and ensure organizations are in the best position to grow safely and responsibly.
