How to Register Your Drone with FAA TRUST and B4UFLY

The two foundational compliance steps for every US drone operator are: (1) TRUST — The Recreational UAS Safety Test, required for recreational flyers under 49 U.S.C. § 44809 — and (2) aircraft registration via FAA DroneZone for any aircraft weighing 0.55 lb (250 g) or more, plus all commercial Part 107 aircraft regardless of weight. The B4UFLY app is the FAA-recognized companion tool for airspace situational awareness.

This guide walks through the complete workflow step-by-step for 2026, with the regulatory citations that define each requirement.

1. The Three Pillars — TRUST, Registration, B4UFLY

2. TRUST — Step-by-Step

What is TRUST?

The Recreational UAS Safety Test is the credential required for recreational drone operators under 49 U.S.C. § 44809(a)(3). It is free, online, takes approximately 20 minutes, has no expiration, and the operator must carry proof of completion during flight.

The FAA's TRUST overview is at https://www.faa.gov/uas/recreational_flyers/knowledge_test_updates. The official portal is at https://uas-trust.faa.gov/.

Step 1 — Choose an FAA-Approved Test Administrator

TRUST is administered by FAA-approved Test Administrators only. Visit the TRUST portal at https://uas-trust.faa.gov/ to select an approved administrator. Common administrators include the Academy of Model Aeronautics (AMA), AOPA, and several drone manufacturer partners. All administrators offer the test free of charge.

Step 2 — Complete the Test

The test contains a series of multiple-choice questions on:

• Federal regulations governing recreational drone use
• Airspace classes and authorization
• Visual line of sight
• Right of way
• Maximum altitude
• Restricted airspace
• Reporting obligations

If you answer a question incorrectly, the system explains the correct answer and you continue. You must answer all questions correctly to receive the certificate.

Step 3 — Save the Completion Certificate

On completion, download the TRUST certificate. Save it on your phone, in cloud storage, and as a printed copy. You must carry this proof during every recreational flight.

Step 4 — Note: TRUST Does Not Expire

Once issued, TRUST is valid for life. There is no recurrent test requirement.

3. Aircraft Registration via FAA DroneZone — Step-by-Step

Who Must Register

Under 14 CFR § 107.13 and 49 U.S.C. § 44101:

• Commercial Part 107 operations: ALL aircraft, regardless of weight
• Recreational operations: Aircraft ≥ 0.55 lb (250 g)
• Recreational operations, < 0.55 lb: Not required

Reference: https://www.faa.gov/uas/getting_started/register_drone

Fee Structure

• Part 107 commercial: $5 per aircraft
• Recreational: $5 per owner (covering all aircraft owned by that individual)

Validity

3 years; renewal required after expiration.

Step 1 — Create a DroneZone Account

Visit FAA DroneZone at https://faadronezone-access.faa.gov/. Click "Create Account" and follow the prompts. You will need an email address, name, and basic contact information.

Step 2 — Choose Registration Type

Select either "Part 107" (commercial) or "Recreational." This selection determines:

• Fee structure ($5/aircraft for Part 107; $5/owner for recreational)
• Required documentation
• The compliance pathway

Step 3 — Enter Aircraft Information

For each aircraft (Part 107) or for the owner profile (recreational), enter:

• Aircraft make and model
• Serial number (from manufacturer documentation)
• Aircraft weight category

Step 4 — Pay the $5 Fee

Pay the registration fee. Credit card or debit card accepted.

Step 5 — Receive Your Registration Number

The system issues a registration number in the format FA-XXXXXXXX. This number must be:

• Displayed legibly on the aircraft's exterior
• Visible without disassembly of the aircraft
• Permanent (not easily removed by ordinary handling)

Step 6 — Mark the Aircraft

Permanently mark the registration number on the aircraft exterior. Common methods: engraved/etched plate, weather-resistant decal, or industrial label maker.

Step 7 — Document the Registration

Save the DroneZone confirmation, expiration date, and registration number. Set a reminder 60 days before the 3-year expiration.

4. Remote ID Compliance Connection

Aircraft registration is necessary but not sufficient. Under 14 CFR Part 89 (effective broadcast enforcement since 2023-09-16), virtually all registered drones must broadcast Remote ID during flight.

Three pathways under § 89.110:

• Standard Remote ID drone with manufacturer DOC
• Broadcast module (FAA-accepted, attached to the aircraft)
• FRIA (FAA-Recognized Identification Area) — flight only

5. B4UFLY — Pre-Flight Airspace Check

What is B4UFLY?

B4UFLY is the FAA-recognized smartphone application for airspace situational awareness. Operated by Aloft (formerly Kittyhawk), B4UFLY shows controlled airspace, restricted/prohibited areas, TFRs, NOTAMs, and the LAANC altitude grid for any location.

The B4UFLY portal is at https://b4ufly.aloft.ai/.

Step 1 — Install the App

B4UFLY is available for iOS and Android. Free download. Account creation is free.

Step 2 — Open Before Every Flight

For every operation, open B4UFLY and:

• Pin your operating location
• Review the airspace class (Class G uncontrolled vs Class B/C/D/E controlled)
• Check the LAANC grid altitude ceiling for your location
• Review active TFRs and NOTAMs
• Verify no restricted/prohibited area conflicts

Step 3 — Submit LAANC Authorization When Required

If your operation is in Class B/C/D/E controlled airspace, submit a LAANC authorization request through B4UFLY (or another LAANC-approved app). For Class G operations at or below 400 ft AGL, no authorization is required.

The full LAANC information page is at https://www.faa.gov/uas/getting_started/laanc.

Step 4 — Save the Authorization

If LAANC issues an authorization, save the unique authorization ID. Document it in your flight log.

6. Common Errors — A Gyoseishoshi Compliance Lens

As MmowW Drone is operated by a licensed Gyoseishoshi (行政書士) office, we observe these recurring errors:

Error 1 — Believing TRUST is sufficient for commercial work TRUST is the recreational credential. Commercial work requires the Part 107 Remote Pilot Certificate.

Error 2 — Failing to mark the registration number on the aircraft The registration number must be visible on the exterior. Operators with paperwork registration but unmarked aircraft fail this requirement.

Error 3 — Confusing the recreational $5/owner with $5/aircraft Recreational operators pay $5 per owner (covering all aircraft). Part 107 commercial operators pay $5 per aircraft. A commercial operator with 5 aircraft pays $25 total.

Error 4 — Letting registration lapse after 3 years Registration expires after 3 years. Operators discovering expired registration must re-register before flying.

Error 5 — Treating B4UFLY as a substitute for LAANC B4UFLY surfaces information about airspace; it does not by itself authorize flight. Authorization is via LAANC submission.

Error 6 — Operating without checking active TFRs NOTAMs and TFRs change frequently — sporting events, presidential movements, disasters. B4UFLY refreshes these at every check; the operator should refresh immediately before flight.

7. Special Cases

Sub-250 g Drones for Recreational Use

Drones weighing less than 0.55 lb (250 g) flown for personal recreational purposes are exempt from registration. However:

• TRUST is still required for the operator
• Remote ID is generally required (some narrow exceptions)
• All other operational rules apply

Foreign Operators

Foreign-registered drones require FAA recognition before commercial flight in US airspace. Foreign pilots conducting commercial operations need separate FAA authorization beyond the TRUST/Part 107 framework.

Self-Built or Modified Drones

Home-built drones or significantly modified aircraft cannot be used in standard operations. They must be operated within an FRIA (FAA-Recognized Identification Area) and follow CBO (Community-Based Organization) safety guidelines.

8. The Best Practice Onboarding Workflow

For a new recreational drone operator:

1. Take the TRUST online (15-30 minutes, free)
2. Save TRUST certificate to phone, cloud, and printed copy
3. If aircraft ≥ 250 g, register via FAA DroneZone ($5/owner, 3 years)
4. Mark the registration number on the aircraft exterior
5. Verify Remote ID compliance (Standard drone, module, or FRIA-only)
6. Install B4UFLY for airspace checking
7. Build the habit of pre-flight B4UFLY check before every operation

For a new commercial Part 107 operator:

1. Pass the UAG knowledge test (~$175, FAA-approved Knowledge Testing Center)
2. Apply for Remote Pilot Certificate via IACRA
3. Register each aircraft via FAA DroneZone ($5/aircraft, 3 years)
4. Mark each aircraft's registration number on the exterior
5. Verify Remote ID compliance
6. Install B4UFLY (or another LAANC-approved app)
7. Submit LAANC authorization for each controlled airspace operation
8. Maintain ALC-677 recurrent training every 24 calendar months
