Aerial survey is a method of collecting geomatics or other imagery data using airplanes, helicopters, UAVs, balloons, or other aerial methods. Typical data collected includes aerial photography , Lidar , remote sensing (using various visible and invisible bands of the electromagnetic spectrum , such as infrared , gamma , or ultraviolet ) and ...
The mystery object flying overhead might be an airplane, not a mystery drone. In New Jersey's case, many airplanes pass overhead on their journeys to and from the New York City region.
Royal Observer Corps aircraft spotters during World War II. It was the creed of the British War Department and the Air Ministry, at the start of the war, that accurate recognition of high-flying and fast-moving aircraft was not possible. The spare-time volunteers of the Observer Corps disagreed and between 1938 and 1939 they started developing ...
People come in and hand you the film and say: 'Be careful with these. We ran outside with our camera because something was flying over our house." [4] As of September 1984, Gersten's group was offering a $1,000 reward for information of the pilots flying the light aircraft out of the Stormville airport. [10]
Flight plans are highly recommended, especially when flying over inhospitable areas such as water, as they provide a way of alerting rescuers if the flight is overdue. In the United States and Canada, when an aircraft is crossing the Air Defense Identification Zone (ADIZ), either an IFR or a special type of VFR flight plan called a DVFR ...
A discrete transponder code (often called a squawk code) is assigned by air traffic controllers to identify an aircraft uniquely in a flight information region (FIR). This allows easy identification of aircraft on radar. [6] [7] Codes are made of four octal digits; the dials on a transponder read from zero to seven, inclusive. Four octal digits ...
[1] A high-flying aircraft can be detected by defense systems at long range, giving an air defense system time to react, alerting surface-to-air missile and anti-aircraft systems and fighter aircraft. Using NOE flight, the approach may be undetected; the aircraft "pops up" to attack the target and then turns to escape before the enemy can respond.
Using this technology planes were able to call in accurate artillery fire and act as forward observers. [1] In 1912 the Royal Flying Corps had begun experimenting with "wireless telegraphy" in aircraft. Lieutenant B.T James was a leading pioneer of wireless (radio) in aircraft. In the spring 1913, he had begun to experiment with radios in a B.E.2a.
