§ Mr. Home RobertsonTo ask the Secretary of State of Defence if he will list the dates, locations, and nature of544W the activity notified, for all instances in which helicopter operators have been informed of particularly intense military lowflying activities in accordance with paragraph 2.4 of aeronautical information circular 156/1993, dated 21 October 1993.
§ Mr. SoamesThe aeronautical information circular, AIC, 156/1993 was replaced by AIC 73/1994 dated 30 June following a working group review of the pipeline inspection notification system—PINS.
The requirement of paragraph 2.4 of AIC 156/1993 does not feature in the new AIC since the working group was satisfied that, in practice, all intense military low-flying activity was already notified to helicopter operators under the existing notice to airmen, NOTAM, system and there was no requirement for additional arrangements.
Since 21 October 1993, almost 6,000 NOTAMs have been issued, covering various types of air activity. To identify those which warned specifically of intense military low-flying activity would incur disproportionate cost.
