necessary before recertification.
Charts are based on published survival statistics following treatment for a particular type of tumour and
may need revision if new therapy is introduced or the results of new studies become available. States can
develop their own charts as guidance for the more common tumours based on the local prognostic factors
and treatments used. Studies used to calculate the certification assessment figures may use overall, eventfree
or disease-free survival, and may include subjects unrepresentative of a pilot population (in terms of
age, sex, country of residence, lifestyle and other variables) and may include cases where curative
treatment has not been attempted. Individual case assessment therefore remains paramount.

Charts are useful for tumours that have a prognosis that improves with time. Some malignancies have a
long median survival time of ten years or more but the rate of progression remains relatively constant
with time. In such a situation it may be possible to maintain certification for several years provided the
licence holder remains asymptomatic, is not on active treatment, and is reviewed regularly.
Tumour Markers
The relapse or active progression of certain tumours may be effectively followed by measuring tumour
markers. The most common example in pilots and controllers is adenocarcinoma of the prostate where
levels of Prostate Specific Antigen (PSA) can be tracked over a period of time.
Analysis of the tumour marker is very useful in determining the risk of relapse for an individual. It is
inappropriate to use a certification assessment chart where this alternative type of specific risk assessment
is possible.

INTRODUCTION
Air Traffic Control (ATC) has developed rapidly since the 1950s. From simple beginnings, it is now a
sophisticated system in which the controller is in charge but in which the machine (i.e. the computer) plays
an important part. The controller processes some of the information but a proportion is processed by the
machine. Technical equipment such as the radar screen, closed-circuit television or visual display unit
(VDU) presents information in a convenient and usable form but it is the controller who has the final
