请问AMM里，system test和operational test区别是什么

一直不了解它们的意义。请各位师傅指导。

system test就是系统测试，相当于比较完整，全面地测试。
operational test就是操作测试，按一些测试电门，操作看看没故障就行。
举例：ATC操作测试，只要在ATC收发机那按一下，看故障灯的情况就好了。
ATC的系统测试，就要用到IFR6000测试仪，要提前联系塔台，真的发射信号，看ATC代码，信号强度什么的。

测试分为：操作测试，功能测试和系统测试。是一级比一级高的。其他回复见1楼

C. Testing - Three Levels
NOTE: After a unit or units are changed or after work has been done on a portion of a system, it is not intended that the entire adjustment/test procedure for the complete system should be accomplished. Only the portion or portions of the adjustment/test procedure that are
applicable need be accomplished, unless specified by the procedure.
(1) Testing information is divided into three categories: Operational Test, Functional Test, and
System Test. Following are definitions of the three categories:
(a) Operational Test: That procedure required to ascertain only that a system or unit is
operable. These tests should require no special equipment or facilities other than that
installed on the aircraft and should be comparable to the tests performed by the flight
crews. It is not intended that the operational test of the unit shall meet the specifications
and tolerances ordinarily established for overhaul or major maintenance periods.
(b) Functional Test: That procedure required to ascertain that a system or unit is functioning in
all aspects in accordance with minimum acceptable system or unit design specifications.
These tests may require supplemental ground support equipment and should be more
specific and detailed than an operational test. It should contain all necessary information to
perform proficiency tests to maintain system or unit reliability at an acceptable level,
without reference to additional documents. A functional test usually occurs during minor
maintenance.
(c) System Test: That procedure containing all adjustment specifications and tolerances
required to maintain system and/or unit performance at maximum efficiency and design
specifications. It shall be self-contained and may duplicate other tests. It is normally used
during major maintenance.
(2) The operational and system tests are normally accomplished at the system level. The general
paragraph at the beginning of each adjustment/test block of pages (page 501 through 599)
outlines the test sequence. The functional test relates to component performance after
installation and is normally contained with the component maintenance practices. The
recommendation to test or not test after a maintenance action is provided at the end of the
appropriate maintenance practices subtopic.
(3) If you cannot complete a test successfully, record the indication or problem, then refer to the Fault Isolation Manual section for that system.

(e) Adjustment/ Test  (A/T) - Page Block 501

1 Operational  Test
This  test  is required to ascertain only that a system or unit is operational. This  test  normally does not require special equipment or facilities other than that installed on the aircraft and is comparable to the  test  performed by the flight crews.
操作测试只是用来确认系统或组件是可操作的。除了安装在飞机上的设备和装备，一般不需要特殊的工装。操作测试和飞行机组进行的测试类似。

2 Functional  Test
This  test  is required to ascertain that a system or unit is functioning in all aspects in accordance with minimum acceptable system or unit design specifications. This  test  may requires supplemental ground support equipment and is more specific and detailed than an operational  test .
功能测试用来验证系统或组件的功能在各方面都满足设计的最低要求。功能测试需要一些地面提供的设备，比操作测试更专业和具体。

3 System  Test
This  test  contains all adjustment specifications and tolerances required to maintain system and/or unit performance at maximum efficiency and design specifications.
系统测试包含了所有调校规范和允许误差，为了维持系统和/或组件性能最高效并满足设计规范。

4 BITE  Test
There are two types of BITE Tests: Main BITE  Test  and Interactive BITE  Test  (Function Code 740).

平时做的基本都是operational 和functional test ,  对于system test做的比较多的都是在MCDU上进行的，对于手册上这段描述翻译得比较拗口，还不是很理解。

航线大多做的是操作测试，

一直以为BITE Test 就是 system test, 今天看来还不是. 请问他们之间有什么区别? 能解释一下吗?
