True. Mode S implementation is slow. They've had the kit for aircraft for
years now and Airbus and Boeing fit it as standard, but many other companies
don't. They argue that until Mode S radars are built to be able to process
the data it is an unnecessary expense. In a way they are right.
When Mode S first came on the scene they knew that aircraft could switch
over quite quickly but it would take years to replace every single Mode A/C
radar with a Mode S radar. It isn't a box you can bolt on to the existing
radar - it's a brand new system. At the last count the CAA have replaced
maybe 70% of their area radar systems with Mode S so still have a way to go.
At airfields the catch up is slower but it is finally getting there because
the CAA now refuse to relicense any Mode A/C systems.
The same is true across the US and Europe but in remoter countries it will
take years for Mode S to become reality> They are not going to want to
upgrade all their aircraft and ground systems in a hurry. It isn't helped by
the fact that even here Mode S is not being made mandatory - thanks to great
opposition from the GA brigade.

The types of aircraft fitted with the right type of transponder must vary
across the globe. Our son was over in Bermuda, in the Island Games, for the
last couple of weeks. He wiled away the odd idle hour watching
FLR24 on his Mini iPad. Apart from the one BA flight per day it appears that
all other flights are from the USA mainland. Of these, he spotted, about
half are private jets.
