Controlled Flight into Terrain

TCAS

Communication and Similar Callsigns

· Use correct RTF phraseology, procedures and discipline at all times;

· Insist on readback. Listen carefully to readback. Always correct errors and insist on correct readback following an error for as many times as it is necessary to ensure that the correct clearance has been understood;

· Monitor flight crew compliance with RTF callsign use;

· Take extra care when language difficulties may exist;

· Recognize and understand the pilots’ working environments and constraints;

· Warn the pilots of aircraft on the same RTF frequency having similar callsigns that callsign confusion may occur. If necessary, instruct one or both aircraft to use alternative callsigns while they are on the frequency;

· A transmission could be blocked when two or more aircraft are responding to the same clearance. Typically the controller would hear a partial or garbled readback.

· If a blocked transmission is suspected, ensure that both aircraft retransmit their messages and confirm that a clearance has not been taken by an aircraft for which is was intended;

· Where an actual or potential callsign confusion incident is observed, file a report using the national mandatory incident reporting system or voluntary incident reporting system as appropriate;

· Advise adjacent sectors/airports if it is felt that potential confusion may exist between aircraft likely to enter their airspace;

· Ensure that aircraft operators are made aware of any actual or potential callsign confusion reported by air traffic controllers.

· Where a collision risk exists, ACAS provides the most effective means of collision avoidance.

· When a controller is informed that a pilot is following an RA, he should not attempt to modify the aircraft flight path until the pilot reports returning to the clearance. He should provide traffic information as appropriate.

The EUROCONTROL Level Bust Toolkit contains further information to reduce the potential for loss of separation.

Exercise 9.3.16 Retell the text.

Exercise 9.4.1 Read and translate the text.

In spite of concerted action throughout the industry, Controlled Flight Into Terrain (CFIT) remains a major accident cause.

According to the IATA Safety Report for 2003 there were eight fatal Controlled Flight Into Terrain (CFIT) accidents world-wide during 2003, which accounted for 136 fatalities.

Sadly, it would appear that three of these accidents involved European operators and took place within the European geographical area - two in Turkey and one in France.

It will be some time before the full details of the accident investigations are available and it is possible that the initial classification as CFIT proves to be inappropriate.

CFIT occurs when an airworthy aircraft under the control of the flight crew is flown unintentionally into terrain, obstacles or water, usually with no prior awareness by the crew.

Pilots and controllers are involved equally in the ATC system, and their responsibilities overlap in many areas and backup.

The pilot-controller confirmation/correction process is a loop that ensures effective communication.

Whenever adverse factors are likely to affect communication, adherence to the confirmation/correction process is alone of defence against communication errors.

Controllers and pilots must work together, but there is a gap in their understanding of each other’s challenges. The pilot is focused on a very complex aeroplane in the demanding environment of approach and landing. The controller is focused on traffic flow. Both are balancing safety and efficiency.

Airline operators something push flight crews with schedule pressures, shortening turn-around times and demanding greater productivity of aircraft and flight crews. They also push the ATC system to increase capacity of landing/takeoff runways, reduce landing intervals, reduce radar separation minimums, and use complex multiple-runway combinations. In this demanding environment, flight safety depends on spoken communication.

Although pilots and controllers work together, sometimes they don’t understand each other’s problems.

A programme on pilot-controller communication should involve pilots and controllers in joint meeting and in joint flight ATC simulator sessions to promote a mutual understanding of each other’s working environment.

Discussions, for example, could include problems caused by late clearances and last-minute runway changes. In the end, these are problems for pilots and controllers.

An example of a successful programme that provided real-world experience and proved the value of mutual understanding between pilots and controllers was that between KLM and Amsterdam ATC.

Controllers participated in Flight Simulator sessions, acting as co-pilot and reading the check-list; on the command of the pilot they operated the flaps, landing gear and other systems; they conducted communications with ATC; and they contributed to decision making in emergency and non-standard situations.

The results of these sessions were very encouraging and resulting in positive advances in mutual understanding being reported by pilots and controllers.

During the 1990s, international collaboration led by the Flight Safety Foundation (FSF) resulted in the development of the FSF Approach and Landing Accident Reduction 9ALAR) Toolkit.

Date: 8 January 2003

Location: Diyarbakir, Turkey

Operator: THY Turkish Airlines

Aircraft Type: Avro RJ100 Regional Jet

Fatalities: Passengers 0 70 / Crew – 5

The aircraft undershot during the final stage of a VOR/DME approach to RWY 34 at Diyarbakir, impacting the ground slightly to the side of the extended centreline of the runway, about 500m short of the runway threshold and 100ft below the airfield elevation. The aircraft broke up during the crash sequence and was destroyed by fire after eventually coming to rest. It is understood that, at the MDA, the pilots did not have visual contact with the runway.

The accident happened in darkness (2020L) and in poor weather. The reported weather at 1950L was: wind, calm, visibility 3.5km, RW 34 RVR 3,500m and falling, and scattered cloud at 4,000ft. However, at the accident location there is a small stream and it is reported that the fog was considerably thicker in this region.

The Turkish authorities recently ruled that the probable cause of this accident was pilot error. More specially, they stated that “the crew was insistent on landing despite the fact that neither the approach lights nor the runway was visible”.

Date: 26 May 2003

Location: near Maska, Turkey

Operator: UM Air 9Ukraine)

Aircraft Type: Yakovlev YAK-42

Fatalities: Passengers 62 / Crew 13

The aircraft was destroyed when it flew into a steep hillside near Maska during its second approach to RW 29 at Trabzon. The accident happened shortly after the crew advised ATC that they were “inbound” towards the Trabzon VOR.

The point of impact was at the 4,300ft level some 25km south of the Trabzon VOR, which is located on Trabzon Airport.

The accident happened in darkness (o413L). The reported weather was: wind 270º/11kt variable between 230º and 300º, visibility better than 10km in light rain showers, and scattered cloud at 1,200 ft. However, it is thought likely that the mountains where the accident happened would have been shrouded in cloud.

Date: 22 June 2003

Location: Brest, France

Operator: Brit Air

Aircraft Type: Canadian Regional Jet CRJ-100

Fatalities: Passengers nil / Crew 1

The aircraft undershot during the final stage of an ILS approach to RW 26L at Brest, touching down about 2,300m before the threshold of the runway and about 450m. To the left of the extended centreline. After coming to rest the aircraft caught fire and was destroyed.

The accident happened in darkness (3251L) and in poor weather: wind 320º/9kts variable between 280º and 360º, visibility 800m in fog, RWY 26 RVR variable between 1,400m and 1,500m, and cloud broken at 200ft and scattered at 2,000ft. The aircraft was operating a flight (AF5672) from Nantes.

The aircraft was cleared to descend to 2,000ft and reached that altitude by about 7DME, continuing at 2,000ft until reaching the Outer Marker (4DME).

A further descent was then made to intercept the Glide Slope. However, this descent was continued, through the Glide Slope, which was crossed at a height of above 1,000ft, and seems to have continued at more or less the same rate until shortly before impact. The warning system “Glide Slope” had commenced, as the aircraft descended below it, 23 seconds before impact. The “Glide Slope” and “Sink Rate” warning continued for the rest of the approach. Meanwhile, the aircraft had been slightly left of the localizer and continued to diverge, steadily, further to the left during most of the rest of the approach.

The either part of the approach had appeared normal but it is reported that the captain, who was handling the aircraft, apparently failed to respond to the warnings or noticeably react as the aircraft descended through the Glide Slope and continued below it. The co-pilot is reported as saying that, following the first “Glide Slope” warning, he had looked at the captain who appeared to be sitting in a normal position, looking towards his instruments, with both hands on the control column. The co-pilot appears not to have commented on the aircraft’s continued deviation below the Glide Slope but, reportedly, he put his hand on the TOGA button. The captain apparently still did not respond. The co-pilot then reportedly increased power and attempted to pull back on the control column, which “felt as if it was blocked”. A few seconds later, the aircraft impacted the ground.
