Applicant certification
Neither the applicant nor any other party to the application is subject to a denial of Federal benefits that includes FCC benefits pursuant to Section 5301 of the Anti-Drug Abuse Act of 1988, 21 U.S.C. Section 862, because of a conviction for possession or distribution of a controlled substance. The applicant hereby waives any claim to the use of any particular frequency or electromagnetic spectrum as against the regulatory power of the United States because of the prvious use of the same, whether by license or otherwise, and requests authorization in accordance with this application. (See Section 304 of the Communications Act of 1934, as amended.) The applicant acknowledges that all statements made in this application and attached exhibits are considered material representations, and that all the exhibits part hereof and are incorporated herein as if set out in full in this application; undersigned certifies that all statements in this application are true, complete and correct to the best of his/her knowledge and belief and are made in good faith. Applicant certifies that construction of the station would NOT be an action which is likely to have a significant environmental effect. See the Commission's Rules, 47 CFR1.1301-1.1319.

Special Temporary Authority application - Explanation
Please explain in the area below why an STA is necessary:
This request for Special temporary Authority (STA) is submitted pursuant to 47 CFR 5.61 to request authorization to perform High Intensity Radiated Field (HIRF) testing. This testing is to be performed in support of an FAA aircraft certification program and is intended to show compliance with 14 CFR 25.1317. The proposed operation is expected to be completed within a period not to exceed two months. Note: requested period is for 6 months to allow for schedule changes should they arise. STA is required because the aircraft and its systems will be subjected to HIRF susceptibility tests including the use of frequencies from 1.5 MHz to 100 MHz.

Special Temporary Authority application - Initial values - Purpose of Operation
Please explain the purpose of operation:
HIRF testing: The operation to be performed includes the execution of low-level coupling HIRF tests comprised of low level swept current (LLSC) tests. The LLSC test will involve illuminating the aircraft with low-level external HIRF field to measure the transfer function between the external field and the aircraft and equipment wire bundle currents. By calculating the ratio between the induced wire bundle current and the illuminating antenna field strength and normalizing this ratio to 1 V/m, the transfer function in terms of induced current per unit of external field strength will be defined. The current induced by the applicable external HIRF environment can then be calculated by multiplying the transfer function by the external HIRF field strength.
