III. OPERATION A. Airborne Team 1. Survey flight patterns Areas to be surveyed and the duration of flights will be subject to the cloud's travel and limitations of the aircraft. Basic strategy of this nature will be determined at HQ and communicated to Robbins AFB. General flight 1 , patterns are prescribed below; details of individual flights and by the observers during flights. Flights will be made,as close as practical, normal to the cloud's path. Aircraft will operate in pairs, flying iden- tical courses but at altitudes differing by about 10,000 feet. After having crossed the cloud in one direction, altitudes will be altered by 5,000 feet for recrossing. Thus, in a typical pattern, planes #1 and #2 would fly at 5,000 and 15,000 feet respectively while crossing in a northerly direction and then at 10,000 and 20,000 feet while crossing back in a southerly direction. Exact. altie tudes will be determined at HQ when the cloud's height has been estimated and/or measured. Deviation from the pre= determined flight pattern to be executed will depend on the accuracy of information available concerning the cloud's location. 2e Flight Schedule: a.
