Capt Stables remarks about the transponders not being switched on interests me.
It was my understanding mainly from reading the stuff that the MoD issues -
for instance on the 'low flying system'
For example, DASC are able to reassure them that it is an MoD requirement3 that ‘Except for aircraft con ducting authorised operational missions, entry to the UK Low Flying System is prohibited unless aircraft are equipped with a serviceable IFF/SSR transpon der and a Mode 3/A squawk with mode C (where fi tted) is being transmitted’.
On collision warning systems;
Which military aircraft have a CWS fi tted? Most UK military transport/‘wide-bodied’ aircraft have TCAS fi tted as do the Tucanos at Linton-on-Ouse. (see page 44 in this issue). While there are currently no military Fast jets with a CWS, the Hawk 128 should have TCAS fi tted when it comes into service, and there is an ongoing evaluation of a possible CWS for the Tornado GR4. No military helicopters currently have a CWS
On mode S;
The Ministry of Defence has a programme to fit Mode S capable SSR transponders to its military aircraft to help protect freedom of movement and improve interoperability
But if they decide not to switch them on then it makes all of this nothing more than window dressing. Anyone with definitive knowledge of whether aircraft in the 'low flying system' must squawk?
