§ 10. Mr. Barnesasked the President of the Board of Trade if he will modify the arrangements for monitoring aircraft arriving at Heathrow so that a count is kept of the proportion of aircraft arriving in both westerly and easterly directions which are instructed to join the glide slope at a height of less than 2,000 feet; and if he will publish these figures in the quarterly statistics of aircraft noise.
§ Mr. Goronwy RobertsThe proportion of aircraft approaching to land at Heathrow which are instructed to join the glide path at a height of less than 2,000 feet is of the order of 2 per cent. Most of these are slow, light non-jet aircraft. The cost of the monitoring proposed would, therefore, be disproportionate to any reduction in disturbance that might result.
