BVLOS waivers exist today but are rare, site-specific, and take 60–90 days to get. Each waiver is for a specific location, operational procedure, and aircraft. You must demonstrate that your operation is at least as safe as standard VLOS operations without the waiver.

What a waiver application must address:
— How you maintain awareness of your drone's position without visual contact
— How you detect and avoid other aircraft (detect-and-avoid system, visual observers, ADSB tracking)
— What airspace you're operating in and why the risk is acceptable
— Your communication and command-link reliability plan
— Emergency procedures for lost link, fly-away, or battery failure
— Population density and ground risk analysis for your specific site

For construction sites specifically: Access-controlled sites are favorable for waiver approval because you can keep uninvolved people out of the operational area, reducing ground risk. This is one of the industry's main objections to the Part 108 draft — it doesn't fully credit these on-site mitigations.

Part 108 shifts from per-mission waivers to an operator certification model. Instead of justifying each flight, you certify your organization's capability to run BVLOS programs.

Key differences from Part 107:
— Operator certificate (not pilot certificate) — your organization gets certified, not just you
— Two tiers: Operating Permit (smaller, simpler ops) and Operator Certificate (larger-scale, higher risk)
— Drones must have a Declaration of Compliance for BVLOS-specific airworthiness requirements
— New roles defined: Operations Supervisor and Flight Coordinator — training provided by your org, no new FAA certificate
— Part 107 Remote Pilot Certificate is NOT required by the rule (though still useful)
— Automated Data Service Providers (ADSPs) required for larger ops — essentially a UTM traffic management system
— Site-by-site FAA approval still required in the current NPRM draft (industry pushed back hard on this)

Good news for construction/industrial: "Shielded operations" (flying near structures) are explicitly addressed in Part 108 — though the initial 50-ft definition is narrower than current waivers allow. Operations at access-controlled sites may get credit for ground risk mitigation in the final rule.

You don't need separate BVLOS study materials to take the Part 107 exam — BVLOS waiver knowledge is not tested. But here's what to learn alongside your Part 107 prep to stay ahead:

Airspace integration concepts: ADS-B (Automatic Dependent Surveillance–Broadcast) — how manned aircraft broadcast position, and how UAS can use ADS-B receivers to detect traffic. Remote ID as a baseline. UTM (UAS Traffic Management) concepts.

Detect and Avoid (DAA): The core technical requirement for BVLOS. Understand the difference between strategic deconfliction (pre-flight planning) and tactical separation (in-flight collision avoidance). Ping transponders, radar-based DAA, visual observer networks.

Risk models: SORA (Specific Operations Risk Assessment) — the international standard for UAS risk evaluation. FAA has been influenced by this framework in drafting Part 108. Understand ground risk class (population density × lethality) and air risk class (airspace type × traffic density).

Operational design: How to structure a repeatable BVLOS program — standard operating procedures, contingency management, crew roles, communication plans. This is what Part 108 operator certification will evaluate.

Global shutter vs. rolling shutter: For photogrammetry (building 3D models from photos), a global shutter captures the entire frame at once — no motion distortion. Rolling shutter cameras (like most phone cameras) capture line by line, which causes "jello" in point cloud reconstructions. Freefly Astro has a global shutter by default. Skydio X10 uses rolling shutter, which limits some high-precision mapping use cases but is acceptable for progress monitoring and inspection.

RTK vs. PPK GPS: RTK (Real-Time Kinematic) gives centimeter-accurate positioning in real time using a base station or NTRIP network. PPK (Post-Processed Kinematic) applies corrections after the flight. Both eliminate the need for ground control points (GCPs) in most workflows. For construction sites, RTK lets you fly without placing survey markers — huge time saver.

LiDAR vs. photogrammetry: LiDAR shoots laser pulses and records point returns — sees through vegetation and gives true surface elevation. Photogrammetry builds 3D models from overlapping photos — cheaper, higher color resolution, but struggles with dense vegetation. For site monitoring and equipment inspection, photogrammetry is usually sufficient. For topographic surveys with vegetation, LiDAR wins.
