One town, two adjacent cells: 400 feet and zero.
Manassas measures 21.5 NM from the DCA VOR/DME, inside the DC Special Flight Rules Area — and Manassas Regional's Class D sits in the middle of it. We verify your parcel's airspace, cell ceiling and authorization path both, before we promise a date. Then we fly radiometric thermal and high-resolution visual capture across 100% of the surveyed surface: the data-center and manufacturing campuses off the Route 28 spine, the airport industrial corridor, the commercial core, and the town's older townhome rows.
- FROM DCA
- 21.5 NM
- STANDING
- Inside the DC SFRA
- POSTURE
- Served with FAA authorization
- CELLS
- Per-parcel. The Manassas city cell was logged at 400 ft; the cell over Manassas Regional's core was logged at 0 ft with no automated approval — adjacent cells, opposite answers.
- COUNTY
- Prince William County
Manassas sits inside the DC SFRA, and Manassas Regional (HEF) is Class D airspace — both require prior FAA authorization under 14 CFR 107.41. Inside the SFRA the standing UAS security NOTAM is VMC-only and bars night as defined in 14 CFR 1.1, so flights are scheduled in daytime and twilight windows. Altitude is set by your parcel's cell or Part 107's 400-foot limit, whichever is lower. A 0-ft cell routes to the manual FAA path; it is not a refusal.

What we inspect in Manassas.
Data-center and manufacturing campuses
The industrial spine along Route 28 and the Prince William Parkway carries data halls, semiconductor and precision-manufacturing plants, and the electrical yards that feed them. Thermal capture reads wet insulation, cooling losses, and connections running warm across roofs and switchyards that never fully stop.
The Manassas Regional industrial corridor
Hangars, maintenance buildings, and low-slope flex roofs packed tight around a Class D field. This is where our per-parcel check does the most work — the corridor sits under cells that range from a full ceiling down to zero, and the answer changes block by block.
Commercial and retail parcels
Center-aisle retail, Old Town commercial roofs, and the service buildings around them. Large flat assemblies over conditioned space show moisture plainly in thermal — located by section, long before a leak announces itself indoors.
Older townhome communities
Manassas holds a deep stock of townhome and garden-apartment roofs, many now past their first replacement cycle. One aerial pass produces a per-building condition record a board can budget against, with no roof access and no ladders.
Substations and switchgear
Findings ranked to NFPA 70B severity classes — the standard your maintenance team already runs — so the report maps directly onto work orders instead of needing translation.

We come back with your parcel's cell reading, the authorization path that applies — including whether the airport's Class D puts you on the manual route — and the flight windows for that specific property, before anyone talks about scheduling.
Manassas, answered.
Can you fly in Manassas? The town is inside the DC SFRA.
Yes. Manassas measures 21.5 NM from the DCA VOR/DME, inside the 30-mile Special Flight Rules Area, and it is core service area for us. SFRA operations run under FAA authorization with NOTAM discipline, which is part of every site's setup rather than an afterthought. We verify the specific parcel before we commit to a date.
Manassas Regional Airport is a few blocks away. Does that change what you can fly?
It sets the rules. HEF is Class D, so the FAA requires prior authorization for our operations there, and the airport's core cell logged a 0-foot ceiling with no automated approval. That means the manual FAA path — filed early, not promised on a date — rather than an automated approval. One cell over, in the city, the ceiling was logged at 400 feet. Same town, two adjacent cells, opposite answers, which is exactly why we read your parcel and never quote the town a single number.
So what altitude will you actually fly over our building?
Whatever your parcel's grid cell allows, or Part 107's 400-foot limit, whichever is lower. We pull the cell at your parcel's centroid and at its corners, because a property line can sit across two cells. Where the profile needs to sit above the cell ceiling, the request goes through a manual FAA path and we file early.
Can you fly at night over a Manassas roof?
Inside the SFRA, no — the standing UAS security NOTAM limits operations to clear-weather daylight and bars night as defined in 14 CFR 1.1. Thermal contrast does peak in the hours after sunset, so for parcels verified outside the SFRA we schedule night capture; for Manassas parcels we plan around twilight and dry-day windows, which still produce strong ΔT separation on a wet roof.
We manage a townhome association here. Is an aerial survey practical at that scale?
It is the practical case. A townhome cluster is surveyed in one aerial pass rather than a roof-by-roof climb, and you get a per-building record — which roofs are dry, which are carrying moisture, and how the findings rank. Boards use it to decide where next year's roof budget goes, and nothing on the report requires anyone to walk a ladder.
Do you publish findings, or name us anywhere?
No. You get a mutual NDA by default, findings are prepared for you and your contractors, and we do not publish client sites, tenant names, or findings. The severity-ranked report is written as scope, not as a sales pitch. Jinki inspects only and performs no remediation, so every finding arrives with the image pair and measurement attached and no conflict of interest behind it.
