![]() Supported by these studies, the average of normals method has evolved into a more general MA approach, which is not necessarily based on “normals” and mean calculations. Since then, studies on this average of normals concept have resulted in (i) alternative methods and new algorithms to calculate average values, (ii) deeper understanding of moving average (MA) error detection and its characteristics and (iii) guidance on how to obtain optimal MA settings. They proposed a method that averages the results obtained within (more or less) the reference range and plotted these in a control chart. Moving average quality control (MA QC) was first described as “average of normals” by Hoffmann and Waid in 1965 as an analytical quality control (QC) instrument. The new insights into MA QC characteristics and operational issues, together with supporting online tools, may promote more widespread acceptance and application of MA QC. Operational MA management issues have been identified that allow developers of MA software to upgrade their packages to support optimal MA QC application and guide laboratories on MA management issues, such as MA alarm workup. Recently developed simulation methods provide realistic error detecting properties for MA QC and are available for laboratories. ![]() Each of the MA QC optimization methods currently available has their own advantages and disadvantages. For this review, relevant literature and the world wide web were examined in order to (i) explain the basic concepts and current understanding of MA QC, (ii) discuss moving average (MA) optimization methods, (iii) gain insight into practical aspects related to applying MA in daily practice and (iv) describe future prospects to enable more widespread acceptance and application of MA QC. Although a potentially valuable tool, it is struggling to meet expectations due to its complexity and need for evidence-based guidance. There is no error and it is really quite simple.Ĭlass: Single Engine -land, Multi engine-sea, etc.Moving average quality control (MA QC) was described decades ago as an analytical quality control instrument. If you have a Private Pilot license you can fly LSA with a drivers license and no medical. Your flight operations are limited the same as any sport pilot. Sport Pilots must have make and model endorsements. Private Pilots do not require make and model endorsements within the same category and class.Įxample: Tom is a Sport Pilot. Both have a drivers license and want to fly a Kitfox LSA with tri gear.ĭick is a Private Pilot with Airplane Single Engine ratings. ![]() Tom must get a Kitfox endorsement before he can solo or carry a passenger.ĭick can jump in the Kitfox, do three take-offs and landings solo, then carry a passenger with no endorsement required. He is a Private Pilot with Helicopter - multi engine - land rating. His medical has expired and he has a valid drivers license. Harry must get an endorsement to fly the Kitfox solo. He may not carry a passenger until he gets an additional Airplane single engine rating. Once again proving I should not make postings after 2200 having left out the nit-pick details. In my original post I tried to make the regs simple, but as everyone knows, simple and FAA in the same sentence do not mix. I normally shy away from these discussions on regs and requirements because they almost always lead to lengthy chatter with little or no positive outcome. ![]() I can barely keep up with the mountain of paperwork with the FAA and no matter how thorough you try to be on the forums, someone will always pop up to point out the errors. When someone signs your logbook, make sure they refer to the AC to get it right.Īnd I’ll do my best to not post when It’s late. The make and model endorsement applies to several of the sign offs required. If you already have a sport license in airplane single engine land/sea then you do not need a make and model endorsement for the Kitfox unless it is your first tailwheel aircraft. ![]()
