Abstract
Many present day controllers rarely experience an incident of a critical nature. Refresher training andChecklists can ensure proper response in emergency. Short training periods of half a day are of
benefit, and the use of case studies is suggested. Regular pilot/controller briefings are very desirable.

EXECUTIVE SUMMARY
This Deliverable and its associated Annexes are produced as a result of a Workshop on theHandling of Unusual Incident held at the EUROCONTROL Institute of Air NavigationServices (IANS), Luxembourg, in April of 1996.
The presentations at the Workshop were in many cases based on real incidents andindividuals concerned were possible to identify. As this is a sensitive area, the actualWorkshop has not been reported on in a formal manner, but this Document uses thepresentations and their content to convey the need for continuation training for air trafficcontrollers in the area. Some examples of the type of incidents are used.
A Checklist is proposed for use in order to ensure proper handling of any incident whichrequires controller action. Suggestions for the content of such a Checklist are included. The
background material has been provided by Germany, Switzerland, United Kingdom and TheNetherlands. Additional input and advice was provided by aircrew personnel from DeutscheLufthansa (DLH).
A simple set of acronyms has been provided which may make it easier for controllers toremember the immediate actions, or sequence of actions, to be followed on initial notificationof any incident.
The Guidelines include some comment on the fact that pilots in general are reluctant to usethe phrases Pan Pan or Mayday. A major exercise in conveying the real benefits of theuse of the Secondary Surveillance Radar (SSR) special codes to pilots should be embarkedon as quickly as possible, using magazine articles, seminars and joint pilot/controller
discussion groups.

1. INTRODUCTION
Many controllers in these days of improved equipment, both in the air and onthe ground, go through lengthy periods without ever having to handle anytraffic situation which presents anything out of the ordinary.
While this trend of increased safety for the flying public is most welcome, itdoes point out the need for the controller to be kept in practice in dealing withany situation which may arise so that when something unusual occurs safetyis not impaired.
Within the EATMP1
(European Air Traffic Management Programme)framework a Work Package which has now become a Specialist Task (ST12)
covering continuation training for air traffic controllers was established at avery early stage. In that context this document was prepared to provide a briefinsight into what is possible, and what is desirable.
A workshop on the topic was held at the EUROCONTROL Institute of AirNavigation Services (IANS) in April of 1996.
A number of presentations were made by representatives from manyadministrations, which detailed the training which they were at that timeundertaking. The presentations were detailed, and sensitive in nature. Theyoutlined in more than one case that the need for continuation training wasidentified only after a controller had obviously become so out of practice in the
handling of the unusual situation, or emergency, that many mistakes of a veryfundamental nature were made. In some case the controllers adopted a flightprinciple in that they tried to behave as though everything was absolutelynormal. They did not seek advice or assistance from their colleagues, nor didthey always deal with the incidents in a professional manner.

2. SCOPE AND PURPOSE OF THIS DOCUMENT
The original intention after the Workshop was to produce a Report whichcontained details of all of the presentations made, but on examination it wasfelt that this might lead to publication of some data which could be regarded asvery sensitive and possibly confidential.
However, there were many points made at the Workshop which are verypertinent to the future training practices in regard to the handling of suchsituations. The Workshop did point out areas which need to be part of anadvisory service for all air traffic controllers. The need to keep colleagues,and the supervisor in the loop was very noticeable, as was the need to providean appropriate level of service to the pilot. Frequency clutter should be
reduced to a minimum, the pilot should be given time and space in which tomake initial attempts to solve the problems.
As each incident, however routine, is nowadays investigated and analysed, aninternational trend became apparent which suggests that:
discussion groups to analyse the incident and the controllers reaction,
support on the counselling front for the controller who has been in positionduring an accident or very serious incident,
the creation of simulation exercises which include the pertinent parts of the
accident/ incident scenarios, and
the use of role playing sessions
were all both desirable and necessary.
The Training Development and Harmonisation (TDH) Unit at IANS, throughthe Training Sub-Group (TSG) of the Human Resources Team (HRT), decidedto create an informal Working Group made up of personnel from MemberStates which had some experience in the matter. To this initial group wasadded, on a voluntary basis, two airline pilots from a major European aircarrier.
In discussion this group reached a broad consensus on a plan of action whichcould be presented to the ECAC (European Civil Aviation Conference) Statesas a Guideline on how to deal with the problem, and a suggested courseformat for any training.

Checklists were discussed at some length and a number of alternative titleswere suggested:
EMERGENCY ACTION GUIDELINE; EMERGENCY COMMUNICATION GUIDELINE;
EMERGENCY REFERENCE LIST; ABNORMAL AND EMERGENCY REFERENCE LIST;
EMERGENCY CHECKLIST.
There was no universally acceptable title. The group did note that anyChecklist must be brief and to the point, and should not be cumbersome insize or operation. Ultimately, the titling of the proposed Checklist is left toeach individual State. The model at Annex A is not intended to be the onlyversion.

4. ACRONYMS AND MNEMONICS
The group noted that the States represented all had some form of simple setsof rules to be adhered to by the controller. The use of abbreviations iscommon in the ATC world and it seems logical therefore to suggest a fewrelevant possibilities:
4.1 RISC
Recognise that there is a problem. Identify the relevant aircraft and arrange for special code Squawk.
Separate - Give the pilots airspace in which to operate and give them time. Communicate with adjacent sectors/colleagues/supervisors as appropriate.
4.2 TAS
Time - Give the pilot time to sort out the immediate problem on receipt offirst notification that there is a difficulty.
Airspace - Give the pilot freedom of the adjacent airspace - get otheraircraft out of the way, and off the frequency.
Silence - The controller should clear the frequency and not raise more
questions than are necessary.
4.3 SSSS
Squawk - Acknowledge the call; make sure the correct squawk isproduced.
Silence - Keep the RTF chat to as low a level as possible - Where possibleassign a single frequency to the incident.
Separate - Provide appropriate and adequate airspace for the pilot to
execute any essential manoeuvres.
Shout - Ask for assistance from the ATC Supervisor and/or colleagues.
4.4 QRST
Quiet - Keep the frequency clear. Recognise that there is a problem when the message is received. Separate - Provide airspace. Time - give the pilot time to work on it.

16/64
HUM.ET1.ST12.3000-GUI-01 Controller Training in the Handling of Unusual Incidents
Page 10 Released Issue Edition : 1.0
4.5 ATIS
Announcing and acknowledging the emergency or problem, getting the
pilot to make the appropriate squawk.
TAQ - Giving the pilot time, airspace and quiet.
Information exchange pilot/controller and controller/controller.
Solving the problem as a team controller/controller and controller/pilot.
4.6 ASSA
Acknowledging the emergency or problem, getting the pilot to make theappropriate squawk.
Separate the traffic and support the pilot in so far as is possible.
Silence - Keep the RTF to a minimum; give the pilot time to think.
Advise Supervisor and appropriate colleagues on other sectors.
4.7 ASSIST
Acknowledge the call; get the squawk.
Separate the aircraft from other traffic. Give it room to manoeuvre.
Silence - on the frequency. Provide separate frequency where possible -this prevents unnecessary clutter for the pilots.
Inform those who need to know and those who can help; inform others asappropriate.
Support the pilots in any way possible - start to think of alternative routings,etc.
Time - Give the pilots time to collect their thoughts, dont harass them forinformation. Time produces good decisions.
The Group does not wish to force any or all of these acronyms on anyMember State. Each is offered as a possibility though it should be noted thatthe DFS already has decided to use ASSIST and has produced some display
items based on it. At Annex B to this Report are EATCHIP/EATMP versionsof some of the items above. Presentation number one has been found to bemost acceptable among an in-house survey of students who have passedthrough the IANS during the early part of 1998.

5. CHECKLIST
There was consensus that there should be two levels of Checklist. The firstshould cover the immediate, urgent and essential actions and the second thesupplementary lists, that is items which were not necessarily essential to becomplied with immediately but which should be used as the situationprogressed. The Checklists should cover each of the different disciplines -
Area, Approach and Aerodrome. The main Checklist should be available atthe working position and more detailed memorandum, providing local or sitespecific data could be added at the supervisors position. The data should beavailable in hard copy though a supplementary copy could be available on anyautomated information system.

7. TRAINING PROGRAMME FOR CONTROLLERS
The length of any training programme is dependent on the intended content,the frequency at which it is conducted, the number of participants and so on.This Group had access to a variety of ATC training schedules. The Groupnoted that, when this type of training is introduced for the first time, it is notalways on a pass/fail basis. When it becomes part of the competencychecking mechanism. it is then subject to the usual rules of assessment whichmay pertain in the individual State.
In the interests of expediting this particular type of training, or re-training, ofcontrollers, it is suggested that in many cases simple programmes lasting onlyhalf of one day could be constructed and administered each year. The more
complex training sessions would of course take a number of days to complete,but would be worthwhile at least in the first instance and subsequently in,possibly, alternate years. It is important that the controller understands thebenefits of clearing the airspace around the particular aircraft, providingsilence on the frequency and getting support from colleagues.
For the shorter courses, the use of a single case study will highlight many ofthe necessary points, and of course if a simulation can be included so muchthe better. In an ideal world, a programme such as JOINT which is mentionedearlier would be ideal as it provides for input from both the pilots and thecontrollers viewpoint.
In any case it is strongly recommended that regular pilot/controller discussionsare initiated so that both sides can discuss a problem as seen from both thecockpit and the ATC unit. Indeed, wherever possible combined trainingsessions could be recommended. Not only will it increase mutualunderstanding of the problems involved from both sides of the incident, but itwill increase the comprehension of the problems and the possible solutions.
In all of the foregoing, no mention has been made of STRESS. During theWorkshop, a number of references were made to this very important topic.One presentation, that from IFATCA (International Federation of Air TrafficControllers Associations), was entirely aimed at the handling of CriticalIncident Stress Management (CISM). A video of this presentation was made
available by IFATCA and this may be had, on request, from IANS. There isalso an EATCHIP Publication dealing with this matter (EATCHIP, 1997). Mostof the training programmes examined include at least a short module on stressmanagement, but post incident support, particularly following loss of life isequally important.
A short example of a Course Content could be (broadly based on input fromThe Netherlands):
a Refresher on ICAO rules pertinent to the handling of unusual situations,both in the air and on the ground;

24/64
HUM.ET1.ST12.3000-GUI-01 Controller Training in the Handling of Unusual Incidents
Page 18 Released Issue Edition : 1.0
a brief discussion between participating controllers and an airline pilotwhere pilot needs could be aired - use one of the above-mentionedacronyms to introduce the subject;
a brief discussion between the participating controllers outlining theirneeds, problems; mention the flight syndrome where a controller maypsychologically refuse to acknowledge that an incident is actuallyhappening; acknowledge that in a PAN PAN or MAYDAY situation theaircraft can not be expected to behave normally;
an outline of responsibilities according to ICAO;
a panel discussion on the content of the course;
a case study which might include an input from some of the participants in
the particular incident;
a summary of the discussions with recommendations on what the controllershould do;
a simulator exercise to allow for some practice of an airborne incident;
a simulator exercise to allow for practice on an aircraft or ATC systemdegradation.
The use of video during these exercises produced some interesting feedback,and should be used only as a teaching/learning aid. The Group noted that
Training for the Trainers is a pre-requisite before embarking on this trainingprogramme. A motto for this type of training could very well be Learning byIncident is better than by Accident.
If possible, and deemed suitable, some controller interface within airlinecockpit training could be an advantage. The Netherlands use this formula andeach controller could expect to be put through the cockpit elementsapproximately once in three years.
The benefits are that a controller could be allowed to:
gain an experience of the impact in the cockpit, during an emergency, of
ATC input;
note how ATC could disrupt cockpit procedures;
note the benefits if ATC provides clear airspace for aircraft experiencingproblems;
participate in the exercise by using the RTF;
go through the cockpit Checklist for the incident;

perform some of the simpler cockpit tasks on pilot instruction (gear, flaps,lights, etc.);
contribute to the decisions;
observe the details of a go-around.
The group has been provided with some data by IANS which emanated fromtheir early courses for ATC Supervisors, and from the introductory module onTeam Resource Management, In each case, a prototype of a Checklist (thatof DFS) had been placed before the participants for comment. In all casesthere was demonstrable enthusiasm for the product.
In such circumstances the group has no hesitation in recommending the useof a Checklist of which an example is attached as a technical annex (see
Annex B Checklist Booklet), or one similar to it.
These TRM courses noted that a Checklist would help the Supervisor as muchas the controller handling the incident as it could provide input on how to workfor a common goal, and to better co-ordinate the operation. Anobserver/assistant working with the controller who uses the Checklist will be ina position to provide better quality support as it will be clear what the controlleris doing, and the sequence in which it is being done.
The proposed Checklist could contain sections on :
ALL AVIATION,
MILITARY AVIATION, GENERAL AVIATION VFR,
ATC SPECIFIC - LOCAL PROCEDURES.
The DFS Checklist contains many suggestions as to which specific incidentsneed to be covered in such a Checklist. Sample pages are reproduced for thebenefit of the reader. The FORMAT of the Checklist may also be of interest.The German item was constructed at approximately A5 size (H210mm xW145mm), with two rings at the top of the pages, and so that the width of thepage fitted into the standard Flight Progress Strip bay, and when opened upshowed the items deemed most necessary for the Checklist in the upper partand the advice and guidance in the lower part. The Checklist is Black Print on
a Red Background. The Netherlands use a system which also fits into a FPSBay, but the single page is full A4 length but half width (H290mm x W145mm).

The lower part of the Document then contains some more detailed data andhighlights the likely complications. It is also black on a red background and isthe same width as that above.
Normally time pressure which requires an immediate landing does notexist.
In normal visibility, an observation of the landing gear should bepossible during a LOW PASS close to the Tower, or other suitableviewing point.
In poor visibility, it may be necessary to have the observationconducted while the aircraft performs a low level overshoot along arunway.
In extreme cases it may be possible to get the aircraft VMC on Topand have another aircraft make an observation.
Technical help could be provided by an aircraft engineer who shouldbe specialised in the aircraft type.
If a safe locking down of the landing gear cannot be accomplished theaircraft may leave the runway at an early stage during the landing.
In circumstances where the ACFT may wish to land in a grass area all
of the adjacent work in taxiways, etc., must be stopped and personnelevacuated.
If a crash landing cannot be avoided the pilot will try to reduce theamount of fuel on board - this will be done by using fuel in flight or bymeans of fuel dumping.
Where available a foam carpet may be required - fire service to activateup to 30 minutes in advance. Such a carpet is effective 15 minutesafter laying and lasts for up to 45 minutes.
Note that FIRE COVER may be reduced at the airfield if the fire trucks
perform the foaming.
