In the USA, controlled airspaces at major airports extend to 12,500 feet or even higher. This creates considerable operational difficulties for aerial survey aircraft above and around large cities. No doubt that in turn this also generates considerable challenges for Air Traffic Controllers to manage airline traffic around a small survey aircraft going back and forth in the middle of their airspace. It is not uncommon that ATC will turn down a survey plane because of excessive workload in their area.
On the other hand, Dat’Air oblique cameras, equipped with longer focal length lenses specially modified and adapted for aerial photography, allow the aircraft to be flown right above the ceiling of the controlled area (+ 500 feet) without disturbing air traffic and often without the need to even request a clearance. Recently one of Dat’Air aircraft flew a large survey within the extremely busy New York airspace at 7,500 feet, just above JFK airport without the requirement to obtain an ATC clearance. This allowed Dat’Air aircraft to fly a very large continuous block of photography uninterrupted, instead of having to cut the area into manageable small blocks around restricted and controlled areas.
Our high altitude approach is considerably more efficient and therefore less time consuming. A mission can be completed in exactly the time allocated to fly it. Dat’Air services include planning, logistics, acquisition, image QC/QA and post processing to the client’s deliverable standards.
“Knowing that these capabilities require very specialized equipment and knowledge as well as a careful, continuous calibration process, Dat’Air services are normally offered as a turnkey solution that our clients can offer to their customers. “
