§ Mr. Mappasked the President of the Board of Trade if he will estimate the cost of provision of further automatic landing operations at Heathrow; and whether the charge will be recoverable from the operators.
§ Mr. JayThe cost of additional ground facilities at Heathrow to achieve international standards for automatic landing in Category II conditions is estimated at £200,000. Further expenditure currently estimated at about £650,000 will be necessary to achieve the standards for Category III B conditions. The Categories are defined as follows:
Category II—Operations to minima below 200 feet decision height and Runway Visual Range 2,600 feet and to as low as 100 feet decision height and R.V.R. 1,200 feet with a high probability of approach success.
Category III B—Operations to and along the surface of the runway and taxiways with visibiilty sufficient only for visual taxying comparable to R.V.R. values in the order of 150 feet.
The cost of aerodrome navigation services, including automatic landing facilities at Heathrow is fully recovered through the Navigation Service Charges.
