Simulate the operation for the characteristic of use, thus ultimately guarantee the integrity of the parts that underwent the test and the good functionality of the product.
LEAK TESTS & FUNCTIONAL CHECKS. The leak tests and the functional checks are implemented as methods for monitoring the production process and for the product quality control.  1 For the purpose of this SIB, a functional check flight is any non-revenue flight performed to assess or demonstrate aircraft serviceability, for in service aircraft already having a valid certificate of airworthiness.  An operational flight check was conducted by (pilot's name) with the following results of the functional check of (system). (Results of the functional check.) These results are within the functional limits called for in (appropriate maintenance reference). A functional check evaluates only a single system within the entire aircraft. This is not to imply that all systems in the aircraft must have a functional check to complete an operational check on th Given an M16A2 rifle that you must confirm is operable. STANDARDS. Perform the function check, ensuring that the rifle operates properly with the selector switch in each position. TRAINING AND EVALUATION. Training Information Outline. 1. Check an M16A2 with the selector lever in the SAFE position (Figure 5-36). Figure 5-36. Selector on SAFE. 2 FUNCTIONAL CHECKS. The functional checks simulate the operation for the characteristic of use, thus ultimately guarantee the integrity of the parts that underwent the test and the good functionality of the product. The parameters that are checked most frequently are: 1  Presence, size and depth of holes. 2  Size of keyway seats. This check is referred to as an operational flight check in the latest revision of the GMM and GOM. A tail rotor has been changed on a BO-105. After the assembly is installed there will be functional checks involving rigging, flapping, and balance. A functional check evaluates only a single system within the entire aircraft. This is not to imply that all systems in the aircraft must have a functional check to complete an operational check on th Func ligh ompendium | 2 Functional Check Flight Compendium Introduction Several accidents and serious incidents have highlighted the higher risk associated with conducting functional check flights (FCF).  Functional testing is a quality assurance (QA) process and a type of black box testing that bases its test cases on the specifications of the software component under test. Functions are tested by feeding them input and examining the output, and internal program structure is rarely considered (not like in white-box testing). Functional testing usually describes what the system does. Functional testing does not imply that you are testing a function (method) of your module or class. Functional testing tests a slice of functionality of the whole system. Functional testing differs from system testing in that functional testing  verifies a program by checking it against ... design document(s) or specification(s), while system testing  validate[s] a program by checking it against the published user or system requirements (Kaner, Falk, Nguyen 1999, p. 52) Some times you need something besides a firearm, and when you do, we are there! Safety/Function Checking a 1911 By. The following steps are necessary when evaluating any M1911-type pistol that you plan on purchasing, in order to verify that the pistol is in safe working condition. SAFETY FIRST: DO NOT attempt any of the following safety checks until you have made ABSOLUTELY certain that the gun is unloaded! Point the gun is a safe direction, then:1. FIRST completely remove the magazine. 2. Lock the slide back, engaging the slide stop.
