MIL-STD-1822A(USAF) APPENDIX A
A.3 DEFINITIONS
A.3.1 In-service periodic tests.
Periodic Serviceability electrical testing is conducted at the System 1 interface connector to assure that the aircraft is capable of MONITORING, SAFING and PREARMING the weapon. Organizational Level maintenance crews perform these checks on aircraft on a nominal 180-day cycle and a 24-month cycle for rotary launchers and pylons.
A.3.2 AMAC surveillance tests.
Surveillance tests are those tests conducted by the Department of Defense (DoD/AFNWC/NCS) for the purpose of determining the AMAC system compliance with the System 1 specification requirements over the life of the aircraft; the data obtained is empirical in nature. These tests are normally conducted once per year on each type of aircraft (see A.4.1).
A.3.3 AMAC certification tests.
These joint SNL/AFNWC/NCS electrical nuclear certification tests are used to determine design compliance of a sample of two to five (2-5) new or significantly modified aircraft. The exact number of aircraft tested is determined using the hyper-geometric mathematical probability model in accordance with the methodology described in NSWOI 99-1. AMAC certification tests consist of:
a. System 1 verification tests of the interface under worst-case aircraft load conditions, including multiple station loading.
b. Functional evaluation of a complete system on the ground using Compatibility Test Units
(CTUs).
c. Functional evaluation of a complete system in flight using CTUs.
On new aircraft or on aircraft that has had major software and hardware changes to its AMAC system, a Full Weapon System Demonstration (FWSD) using a Development Joint Test Assembly (DJTA) may be required.
AMAC testing will be completed on every new weapon system or when there has been a major modification to the AMAC system. Both ground and flight tests will be performed for new systems. Modifications to the AMAC system will require testing using all or a subset of required AMAC tests. After initial nuclear certification, the DoD and NNSA (Sandia National Labs) will jointly make the determination of whether a modification is major or minor. As a minimum, ground tests will be performed for systems with major and minor modifications. Flight tests will be done for modified systems, as necessary, to ensure that the AMAC system functions correctly in a normal flight environment.
A.3.4 AMAC periodic tests.
The purpose of these tests is to verify that no degradation to the AMAC system has occurred that would jeopardize the aircraft's capability as stated in the Aircraft Compatibility Control Drawings (ACCDs) due to modification or aging, and to assure that the reliability numbers published by DoE are supportable. These tests are conducted on AMAC systems that have not been modified or tested for an extended period. During this period, there could have been many conventional changes to the aircraft that, at first inspection, did not affect the nuclear system; these tests are used to confirm that no change has occurred. Periodic AMAC tests are typically conducted every five years (up to a maximum of ten years) to determine if the aircraft/bomb weapon system continues to meet the System 1 Specification and perform AMAC
