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 on an EMBRAER aircraft. The proposed operation is expected to be completed within a period of approximately one month and is not expected to be repeated. STA is required because the aircraft and its systems will be subjected to HIRF susceptibility tests including the use of frequencies from 10 MHz to 18 GHz.

Nature of Service:

Experimental

Special Temporary Authority application - Initial values - Purpose of Operation

Please explain the purpose of operation:

The operation to be performed includes the execution of low level coupling HIRF tests comprised of low level swept current (LLSC) and low level swept field (LLSF) 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, EMBRAER will obtain the transfer function in terms of induced current per unit of external field strength. The current induced by the applicable external HIRF environment can then be calculated by multiplying the transfer function by the external HIRF field strength. The LLSF test will be performed on the aircraft from 100 MHz to 18 GHz. The internal RF fields in the vicinity of the equipment will be measured instead of the wire bundle currents. The relation between the internal and external fields provides the attenuation of the structure for each tested location.
