For example, all British civil aircraft have a five-letter call sign beginning with the letter G. Canadian aircraft have a call sign beginning with C–F or C–G, such as C–FABC. [1] Ground-effect vehicles (hovercraft) in Canada are eligible to receive C–Hxxx call signs, and ultralight aircraft receive C-Ixxx call signs. In days gone by ...
The natural outcome of this requirement is a wing design that is thin and wide, which has a low thickness-to-chord ratio. At lower speeds, undesirable parasitic drag is largely a function of the total surface area, which suggests using a wing with minimum chord, leading to the high aspect ratios seen on light aircraft and regional airliners ...
Aviator call signs nearly always must come from a member or members of the aviator's squadron, training class, or other cohort. It is considered bad form to try to give oneself a call sign and it is also common for aviators to be given a fairly derogatory call sign, and the more they complain about it, the more likely it is to stick.
The two aircraft had landed at Los Rodeos earlier in the day, and were among a number of aircraft diverted to Los Rodeos due to a bomb explosion at their intended destination of Gran Canaria Airport. The airport had become congested with parked airplanes blocking the only taxiway , forcing departing aircraft to taxi on the runway.
Aeronautical phraseology is a set of communication rules for simplified English language communication between an air traffic controller and the pilot in command of an aircraft. [1] In the majority of countries, the aeronautical phraseology in use is based on standards developed by the International Civil Aviation Organization .
Russian nuclear icebreaker Arktika with call sign UKTY. Merchant and naval vessels are assigned call signs by their national licensing authorities. In the case of states such as Liberia or Panama, which are flags of convenience for ship registration, call signs for larger vessels consist of the national prefix plus three letters (for example, 3LXY, and sometimes followed by a number, e.g. 3LXY2).
An ASH 31 glider with very high aspect ratio (AR=33.5) and lift-to-drag ratio (L/D=56) In aeronautics, the aspect ratio of a wing is the ratio of its span to its mean chord. It is equal to the square of the wingspan divided by the wing area. Thus, a long, narrow wing has a high aspect ratio, whereas a short, wide wing has a low aspect ratio. [1]
Aircraft position within a flight. Use if specific call sign is unknown. Data Standby for improved data modem (IDM) data message concerning (object) at stated location. Datum Last known position of a submarine contact after contact was lost. Deadeye Informative call by an airborne laser designator indicating the laser/IR system is inoperative ...
