Crop Circle / Jejak UFO di Yogyakarta

Beruntung sekali bisa menyaksikan fenomena crop circle ini secara langsung dari udara. Pengalaman yang mengasyikan. Gambar ini di ambil tadi pagi saat terbang di Yogya. Bentuknya yang artistic dan mulus berbentuk lingkaran membuat saya asyik menyaksikannya. Beberapa kali saya terbang mengelilinginya seolah tidak mau rasanya untuk beranjak, benar benar sempurna, subhanallah. Fenomena yang sangat langka ini belum terpecahkan bagaimana proses terjadinya, namun apabila dilihat dari bentuk dan polanya sangat sulit apabila jejak itu di buat oleh tangan manusia. Percaya gak percaya ini nyata ada. Menjadi saksi mata yang melihat dari udara menyimpan...

Transponder Code

Transponder codes are four digit numbers transmitted by the transponder in an aircraft in response to a secondary surveillance radar interrogation signal to assist air traffic controllers in traffic separation. A discrete transponder code (often called a squawk code) is assigned by air traffic controllers to uniquely identify an aircraft. This allows easy identity of the aircraft on radar. Squawk codes are four-digit octal numbers; the dials on a transponder read from zero to seven inclusive. Thus the lowest possible squawk is 0000 and the highest is 7777. There are 4096 permutations of these four digit codes, which is why they are...

Transponder ( Transmitter Responder)

A transponder (short-for Transmitter-responder and sometimes abbreviated to XPDR, XPNDR, TPDRor TP) is an electronic device that produces a response when it receives a radio-frequency interrogation. In aviation, aircraft have transponders to assist in identifying them on radar and on other aircraft's collision avoidance systems. Air traffic control units use the term "squawk" when they are assigning an aircraft a transponder code, e.g. "Squawk 7421". Squawk or squawking thus can be said to mean "select transponder code" or "I have selected transponder code xxx...
