                              Exhibit: General Application Letter
              Purpose: Address Form 442 Question 7: Experimentation Description

Federal Communications Commission
Experimental Radio service
Subject :      Request for Special Temporary Authorization (STA)
               High Intensity Radiated Field (HIRF) – Gardener, KS
               Ref 0393-EX-PL-2012 (Current Project)
               Ref 0632-EX-PL-2011 (Previously Approved STA for similar project)

This request for a Special Temporary Authorization (STA) is submitted in accordance with CFR
47, part 5.61. The purpose of this STA is to perform Low Level Swept Coupling (LLSC) testing on
a Part 23, 25, 27, or 29 aircraft, for the purpose of aircraft threat development for a High Intensity
Radiated Field (HIRF) environment. The threat development determines the required equipment
bench test levels. This test is required to satisfy applicable HIRF certification directives. Further
details are provided below.

Need for special action: The tests to be conducted include the use of swept frequencies from
500 KHz to 18 GHz with the exception of prohibited frequency bands. Testing using widely
spaced discrete frequencies would miss possible critical resonant frequencies. The proposed
testing will include the following.

From approximately 500 KHz to 400 MHz, the aircraft under test will be illuminated with a known
low level swept frequency electromagnetic field and the resulting induced cable bundle currents
will be measured on the aircraft using current probes.

From 100 MHz to 18 GHz, the aircraft under test will be illuminated with a known low level swept
frequency electromagnetic field and the resulting electromagnetic field strengths will be measured
within the various compartments of the aircraft.

Time and Date: Testing is planned to occur between the dates of August 1, 2012 and February
1, 2013.
Location: Proposed testing will occur at the Garmin Flight test facility at New Century Airport,
Gardener, KS. This is a company owned facility at the coordinates N38 Deg, 53.307 Seconds,
W094 Deg, 51.650 Seconds.

Field Generation and Monitoring Test Equipment
Reference the Antenna Exhibit for equipment information.

Frequency Bands and Power:
Reference the Antenna Exhibit for further supplemental information on test frequency,
modulation, and Effective Radiated Power (ERP).
