Flight progress strips

Flight progress strips at Prestwick: from wartime movement boards to paper strips at the ADC and APC desks in the 1980s, the UK strip colours, and electronic strips.

What it is

  • Each flight gets a strip that moves between bays on the board as it progresses. UK colours (CAP 493): buff = arrivals, blue = departures, pink = local, green = transit.
  • Boards have a runway bay, and “LVP in force” strips can be displayed. Alternative (electronic) systems need CAA approval.

How controllers use it

  • Example: a Ryanair arrival’s buff strip moves from the inbound bay into the runway bay when the aircraft is cleared to land.
  • Retention: paper and electronic strips 30 days; the watch log 12 months.

UK rules and practice

  • NATS EFPS (NAV CANADA EXCDS) started at Stansted in 2004, then Edinburgh, Aberdeen and Glasgow in 2010.

At Prestwick

  • The strips on this page are generated from the site’s live ADS-B and ground data: buff for aircraft closing on Prestwick, blue for those leaving, green for nearby transits, and grey for aircraft on the ground at the field.

Typical UK practice: Whether Prestwick uses paper or electronic strips today is not public. atchistory photos show paper strips at the ADC/APC desks around 1984.
