HL Deb 11 December 1975 vol 366 c1200WA
Lord TREFGARNE

asked Her Majesty's Government:

How many British registered aircraft will be affected by introduction of 25 kHz spacing on the VHF aeronautical communications band and what estimates have been made of the cost of this change to the Civil Aviation Authority and to British aircraft operators.

Lord WINTERBOTTOM

This matter falls within the responsibility of the Civil Aviation Authority and I have asked my right honourable friend to draw the attention of the Chairman of the Authority to the noble Lord's inquiries.
