Downloaded from https://www.everyspec.com 3.1.34. Integrated Flight and Fire Control (IFFC). The coupling of the flight control system to the fire control system to improve combat effectiveness. When selected by the pilot, the IFFC aligns the aircraft andlor weapon system with the target. Once the weapon has locked onto the target, the flight control system assists the pilot in maintaining the target within the weapon system's engagement envelope. Consisting primarily of software, the IFFC relies on mission tailored control laws and cueing symbology. The IFFC reduces fire control timelines. To ensure flight safety, the IFFC must be capable of being overridden by the crew at any time. 3.1.35.
Interim Statement of Airworthiness Qualification (ISAQ). A document establishing a preliminary or provisional qualification status and an airworthiness release when issued in conjunction with an AQSR. Examples of occasions when an ISAQ may be issued in lieu of an SAQ are when testing is not completed, when limited production has been started. when an item is found to be safe but with some ~erformance shortcomings, or'after qualification is essentially complete but pending final documentation approval. See Statement of Airworthiness Qualification (SAQ). 3.1.36. Interval. The elapsed time between the separation of a store and the separation of the next store.
The minimum release interval is the shortest allowable or usable interval between successively released stores that will allow safe separation of the stores from the aircraft. 3.1.37. Jettison, emerqency. The intentional simultaneous, or nearly simultaneous, separation of all stores or suspension equipment from the aircraft in a preset, programmed sequence. 3.1.38. Jettison, selective. The intentional separation of stores or suspension equipment, or portions thereof such as expended rocket pods that are no longer required. 3.1.39. Launch. The intentional separation of a self-propelled store such as a missile, rocket, or target- drone for purposes of employment of the store. 3.1.40.
Mean point of impact (MPI). A point which has as its rangeldeflection coordinates the arithmetic mean of the range and deflection coordinates of the impact points. 3.1.41. Mini-weapons survey (MWS). A limited set of analyses and tests that substantiate that a modification to an existing system has not adversely affected safety, airworthiness, or the operational capability. The survey includes limited weapons firing. Primary interests are compatibility and "safe functionality". If accuracy is assessed, it is done so from a qualitative perspective rather than quantitative statistical. 3.1.42. Misfire. A failure to fire, shoot or launch a munition when the trigger or switch is activated.
