Abstract
Recent advances in technology have encouraged proposals
for new approaches to ATC in Europe
and elsewhere. Two such proposals, both rather loosely framed,
are for ‘free flight’ or for
‘seamless contracts’; otherwise ‘tubes of
flight’. These concepts, and variations on them, aim
to increase the traffic capacity of the airspace. They have been the subject
of numerous
published papers. Given the declared objects of these systems, it is surprising
that, nearly
without exception, these papers discuss the proposals only in qualitative
terms. The present
paper discusses idealised versions of these systems on the basis of quantitative
studies. It is
concluded that the ‘seamless contract’ is
very probably unworkable in Europe. ‘free flight’
is workable in principle, but there is a need for investigation of possible
mechanisms by which
last-minute problems may be resolved.
