TECHNICAL РRОBLЕMS AND COMMUNICATION FAILURE

PIL: Sunair 779, transmitting blind due receiver failure. Sunair 779, FL 130, heading 110. Over WD, descending to FL 90 runway 32. Request landing at your aerodrome.

ACFT: Mayday, Mayday, Mayday. Winton Control. Finair 245. Unsure of my position. Request my position.

CTL: Sunair 245. Winton Control. For identification turn right heading 145.

ACFT: Turning right heading 145. Finair 245.

CTL: Finair 245. Identified 100 km east of Winton. Resume own navigation to DZ.

ACFT: Resuming own navigation to DZ.

PIL: Sunair 725, request divert to Overby, a passenger is seriously ill, probably a heart attack.

CTL: Roger, Sunair 725, turn right heading 290, I'll tell Overby you require medical assistance upon arrival.

PIL: Turning right 290, Sunair 725.

For voice communication purposes civilian air traffic uses two ranges of frequencies: Very High Frequency (VHF) and High Frequency (HF). VHF radio is used for relatively short distances (up to 200 miles) and is therefore suitable for populated areas where transmitters can be provided comparatively close to each other to ensure complete radio cover. There are 760 VHF voice radio channels available for air traffic use.

HF (or short wave) radio is used for long distance communication covering hundreds or even thousands of miles. Civil and military air traffic over the oceans of the world and over sparsely populated continents, such as Africa, communicate with radio base stations on HF using a wide range of frequencies which are varied according to the different qualities of reception which occur throughout the year and from day to day.

Whenever a civil or military aircraft carries a member of the Royal Family in the UK, an area of purple airspace is created which is intended to protect the Royal Flight throughout its journey. Usually the Royal Flight will be routed along the normal UK airways system and through established control zones, and the airspace will then be declared Purple Airspace.

LONDON AREA & TERMINAL CONTROL CENTRE

The larger of the two UK air traffic control centres is at West Drayton, a few miles north of Heathrow.

Control of the London Flight Information Region (FIR) sectors takes place from the Operation Room. The centre provides a continuous service with five shifts with a total of more than 400 air traffic control officers and 200 assistants. More than 3,500 flights are handled by West Drayton every day.

For every flight using controlled airspace, a flight plan will be filed giving details of the flight. The information is held in the computer before the flight enters the London control area, when a ‘Flight Progress Strip’ is printed. This provides the controllers with details of the flight on a thin cardboard strip, mounted on a plastic holder. Strips of various colours are used to give rapid identification of flights of different direction.

As each flight comes within the jurisdiction of a particular sector team, the flight progress strip is marked to indicate the various instructions passed to the pilot. The controller or assistant dealing with the flight marks the strip as the words are being spoken so that the possibility of mistakes is reduced to minimum.
