An interesting Parliamentary Question was answered today about Mode S. The
Army's Watchkeeper Remotely Piloted Air System which is currently undergoing
test flights from Parc Aberporth is Mode S equipped. Another type to consider
when looking at tie-ups for new UK Mil hexes.
Unmanned Air Vehicles
28 Feb 2011 : Column 84W
Angus Robertson MP: To ask the Secretary of State for Defence which unmanned
aerial vehicles are equipped with (a) an approved Sense and Avoid capability and
(b) a Secondary Surveillance Radar Mode S transponder; [41954]
Which types of unmanned aerial vehicles can fly in each classification of UK
airspace; [41955]
Peter Luff (defence minister): Within the UK, unmanned aerial vehicles (UAVs)
procured by the Ministry of Defence operate only in segregated airspace,
specifically restricted airspace (temporary), and in danger areas.
The following table provides details of MOD procured UAV flights in UK
segregated (i.e. restricted) airspace and in danger areas, in each of the last
three financial years.
UAV Watchkeeper
Type of airspace Segregated Danger area
2008-09 0 0
2009-10 0 0
2010-11 (to date) 13 1
No MOD procured UAVs are equipped with an approved sense and avoid capability.
The Watchkeeper UAV, which is not yet in-service, is fitted with a Secondary
Surveillance Radar Mode S Transponder. No other MOD procured UAV has this
capability.
