Additionally, <br /> aeronautical study confirmed that the temporary structure will have no physical or electromagnetic effect on the <br /> operation of air navigation and communications facilities and will not impact any airspace and routes used by <br /> the military. Based on this aeronautical study,the FAA finds that the temporary structure will have no adverse <br /> effect on air navigation and will not impact any aeronautical operations or procedures. <br /> Based on this aeronautical study, the structure would not constitute a substantial adverse effect on aeronautical <br /> operations or procedures because it will be temporary. The temporary structure would not be considered a <br /> hazard to air navigation provided all of the conditions specified in this determination are strictly met. <br /> Based on this evaluation, marking and lighting are not necessary for aviation safety. However, if marking/ <br /> lighting are accomplished on a voluntary basis, we recommend it be installed in accordance with FAA Advisory <br /> circular 70/7460-1 L Change 1. <br /> It is required that the manager of DANE COUNTY RGNL-TRUAX FIELD, (608) 246-3380 be notified at least <br /> 3 business days prior to the temporary structure being erected and again when the structure is removed from the <br /> site. <br /> It is required that the manager of Air Traffic Control Tower at 608-244-5691 be notified at least 3 business <br /> days prior to the temporary structure being erected and again when the structure is removed from the site. <br /> Additionally, please provide contact information for the onsite operator in the event that Air Traffic Control <br /> requires the temporary structure to be lowered immediately. <br /> This determination expires on 12/01/2018 unless extended, revised, or terminated by the issuing office. <br /> NOTE: REQUEST FOR EXTENSION OF THE EFFECTIVE PERIOD OF THIS DETERMINATION MUST <br /> BE E-FILED AT LEAST 15 DAYS PRIOR TO THE EXPIRATION DATE. AFTER RE-EVALUATION <br /> OF CURRENT OPERATIONS IN THE AREA OF THE STRUCTURE TO DETERMINE THAT NO <br /> SIGNIFICANT AERONAUTICAL CHANGES HAVE OCCURRED,YOUR DETERMINATION MAY BE <br /> ELIGIBLE FOR ONE EXTENSION OF THE EFFECTIVE PERIOD. <br /> Page 3 of 4 <br />
