For MAYDAY was created? No one in the mind would be free to help

Even if you try to call Help in the radio waves with the utmost care, it will disappear freely. That is why the new label tsun MAYDAY was created ninety years ago. A word that has my pbh.

MAYDAY-MAYDAY-MAYDAY, Charlie Bravo 75, struck by lightning, a sharp drop in the cockpit, the voice of the Falcon pilot jerked on the frequency of the HT sector, muffled by an oxygen mask.

Charlie Bravo 75 MAYDAY ROGER, enrolled dc in the sector and the rally began to divert conflict traffic from his work. His reaction was symptomatic. When, in the next few seconds, he warned carefully at the right moment to address the pilot, his eyes literally hung on a vertical rate of descent. It was so high that it could not be reliably displayed on the radar. In addition to the bursts of static fights, which accompanied a wave of summer storms in the afternoon, and one more rhythm on the connection, there was one regular rhythm in the headphones. Your own heartbeat.

The word MAYDAY has such a service in aviation.

Him who figured out how to call for help

The author is certainly Frederick Stanley Mockford. He was born on December 8, 1897, and after graduating he joined the London-Brighton and South Coast Railway, where he became a telegraph operator at the age of just eight years. After the outbreak of the First World Wolves, he volunteered for the Royal Flying Corps (RFC). The unit left for France and in the spring of 1917.

In Britain, he was responsible for training personnel in wireless communication and installing the necessary equipment in various types of aircraft, especially the bomber. On the fronts of the Great Wolves, wireless communication between the ground and the aircraft was first used effectively in 1914, when the pilots of the 4th Squadron of the RFC killed artillery fire through it. During the wolves, Mockford gradually worked with several squadrons: the 39th Squadron of the militia, the 78th Squadron RFC and the 141st Squadron RFC, in which he finally demobilized in 1919.

In civilian life, at the newly established Ministry of Aviation, he became the person responsible for the development and implementation of a wireless connection to the air force. He was the first inspector to examine adepts of telegraphic licenses in the Air Force. He also worked in the posting center of the main air port in Britain, then the only international flight Croydon, where he was appointed in 1923 as an old radio officer.

Croydon was formed in 1920 by merging two nearby airfields, Beddington Field Flight, from which the British de Havillands and later Sopwiths took off from 1915 to defend against the German airships Zepellin, which sent death in the streets of London, and the factory flight Waddon, which since 1918 was used for testing Airco DH9 (de Havilland) bombers manufactured by National Aircraft Factory No. 1. After the war, the French, British and German bombers were converted into transport machines and became five airborne transporters in Europe.

Some prominent personalities are thus associated with Croydon. George VI, Edward VIII, but also Winston Churchill underwent air training here. To return to the historically first pellet of the Atlantic in May 1927, the Charles Lindbergh pistol and British airman Amy Johnsonov took off from here in 1930 for their word flight to Australia. The biggest bank robbery took place here in 1935, when a bird thief robbed a summer safe and took a plowed gold brick worth 12 million pounds. It should be noted, however, that the only guard to fly was to fly an unarmed party. To fly to Croydonsk Agatha Christie introduced the DJ Romna Vrada in the Clouds.

The city where the zen of air traffic was born

Today, this city, forgotten by the city of South London, has a few known firsts in the history of aviation. The profession of air traffic was born here.

Jimmy Jeffs, an aviation enthusiast and great innovator, became the ATC license holder in 1922. At that time, they issued a light signal to start and piste and tried to find out some kind of traffic. Wireless radiotelegraphy and new radiotelephony were widely used, through which the first NOTAMs were first published, in which pilots were informed about the time, the recommended direction of approach and the availability of technical means.

The area around the fly became a sign, and to maintain safety, the pilots were required to accept the rules for skin and departure. The rapidly evolving system also allows zooming even with reduced visibility. The result in the set of new Q-kds accelerated communication between the ground and the aircraft.

Frederick Mockford has been active in a series of international conferences on wireless communication. Thus, new safety standards were introduced (owners, compulsory travel, flight routes, age of flights, departures and route), in essence, this was a response to the very first number of commercial aircraft in history, which took place in April 1922 about a hundred kilometers north of Pae near the town of Grandvilliers.

When the radio arrived, MAYDAY and PAN-PAN were formed

A major breakthrough in the transmission of information occurred after the discovery of radio wave modulation behind the word transmission, then music. Thus, the words of the radio came to the audience prominently and, as a miracle, the spoken word. And first with them, in the Air Force came to the forefront of efforts to understand and unambiguous messages sent. That’s why Mockford with a phonetic alphabet, like A Alpha, B Bravo, C Charlie, who has played his irreplaceable role to this day, would go through only minor variations.

With the more frequent opening of air frequencies, there was one crucial need. At that time, there was only one SOS signal, internationally valid since 1908, which was used only by telegraph. The SOS file set is still mistaken for the imaginary connection of the letters with the message Save-Our-Souls (save our reason), but the real reason is to try. Those flows, those rivers, those flows are the simplest axiom of emergency, which is easily taken away even by an untrained hunter.

Despite the introduction of a number of technical innovations, the pilots relied primarily on comparative navigation, which is why the flight route between London and Pa was led primarily over the railways. Flight graphics come from the International Air Guide 1932, Route Maps, the predecessor of the Jeppesen day system.

Mockford was first encouraged to come up with a phonetic label that was the most obvious, which would be clear and unmistakable. In view of the fact that the fifth flight operation took place between Croydon and the Le Bourget belt, Piel Mockford with a genius derivative of the French connection venez maider help me to poanglitl and at the same time more pronounced MAYDAY.

By the way, try to pronounce English HELP yourself with an attempt to be as expensive as possible. In addition, the disintegration of radio waves condemns the urgency of an unfamiliar one-weak verb, in an imperative manner, to utter extinction. Mockford realized this, and he rehearsed patiently during the rehearsal. The International Telegraph Union officially adopted the MAYDAY signal as a phonetic variant published in 1927.

A similar history has been given to the emergence of an emergency, which is PAN-PAN, or the French virgin means in Czech Republic failure, failure. This word, uttered in succession, expresses others not threatened with enough urgent help. Frz PAN-PAN medical then the pilot announces a health problem on board.

He finished his career at Mockford in 1930, when he decided to work for Marconi. Over the years, he has held a number of senior positions. In 1947, he became sales director of Marconis Wireless Telegraph Co. Ltd and remained in this position until 1961, when he retired.

He was never appreciated at home

During the Kinds of Worlds wolves were brought by his son Patrick Alfred Kingsley Mockford ob nejvy. In April 1943, his Lancaster patrol of the 207th Squadron of the RAF at the northwestern part of Denmark was hit by German flak. The crew died while trying to make an emergency piston during the cell. Of the two hundred planes that took off that night, mines from the Elbe River and the Great Tidal River flowed in, twenty-two did not return. It was not until twenty years later that navigator Patrick Mockford, who was on his nineteenth mission, did not have time to send his signal.

Frederick Stanley Mockford led the various life associations, was a founding member of the Industry Council, an active member of the Electronic Engineering Association, the Institute of Navigation and a member of the Royal Society of Arts. The day from the British authorities never appreciated his services in the Air Force, but he received great honor when the Icelandic president awarded him the highest island honor, the Icelandic Falcon, the fifth (engraving) degree. During his lifetime, he was a witness to the emergence of the aviation industry and its subsequent literally rocket transformation. He died on February 1, 1962, and is buried in Selmestone, another Sussex, alongside St. Winifred.

Every hunter needs help in life, but not who can read about it. Definitely not that with the use of a single word, problems can be automatically cleared from his life. The MAYDAY signal has become the shortest line of assistance in aviation, considered one of the most complex fields of human performance. It is thus claimed by example, and in simplicity it is sla.

A salt that has been saving lives for nineteen years.
