§ Martin LintonTo ask the Secretary of State for Transport if he will publish the results of the two-year trial, beginning August 2000, to extend night period runway alternation at Heathrow to the hour between 6 am and 7 am; and if he will make a statement. [89536]
§ Mr. JamiesonThe trial was expected to run for about two years. During 2002 it was affected on approximately 35 per cent of mornings by engineering works, including replacement of the instrument landing systems (ILS), runway resurfacing and replacement of runway lighting. Completion of the resurfacing work on the southern runway has also been delayed, and will resume in April. Consequently it is not possible at this stage to draw any firm conclusions from the trial, which will need to continue for a sustained period following the completion of the engineering works later this year.
