Rotax Fuel Injected 912 iS / 915 iS Installation & Operation Price Member - £200, Non-Member - £220 Duration Arrival 09:30. Finish 17:00. < Back About the Course With the growth of interest in the fuel-injected Rotax 912 and 915 iS series engines, it has become apparent that there is a lot of confusion and misunderstanding about the installation and operation of these engines and the way that the latest built-in systems work. Electronics and Rotax iRMT certified engineer, John Barrott, was an early installer of a 912iS and found it difficult to find accurate information on best practice. Working with UK Rotax agents CFS and LAA Engineering, John has built up a comprehensive understanding of the iS engines and has developed a course around this to provide help and advice on the installation and operation of this new generation of aero engines. The course is classroom (not workshop) based. Your Instructor John Barrott Dates To be confirmed Times Arrival 09:30. Finish 17:00.

< Back Mandatory Technical Directive issued for Supermarine Spitfire mk26 and mk26a 16 Feb 2024 It has been found that there is potential for the fin of the Supermarine Spitfire Mk26 and 26B to be misaligned during build, due to a build-up of tolerances in the fin and its attachment, possibly leading to a mis-rigging of the rudder and failure to achieve the desired range of rudder travel. This could possibly result in degraded controllability in flight and on take-off and landing. In the interests of safety MTD 01-2024 calls for mandatory checks to be made on the fin alignment and rudder range of movement. Next Previous

Working with Aluminium - Basic Course Price Member - £250, Non-Member - £270 (includes toolbox) Duration Arrival 09:00. Finish 17:00. < Back About the Course The 'Working in Aluminium' courses have proved immensely popular, as so many of the popular kits today use this medium. Our tutors will guide you through the construction of a Van’s toolbox. The build process is specifically designed to teach you drilling, de-burring, dimpling and riveting by various methods, and by the end of the day you will have a useful ‘apprentice piece’ to take home with you. The course syllabus will include: measuring and marking, cutting and drilling, deburring, fluting and straightening, countersinking and dimpling, and, the bit you’ve been waiting for, riveting; in fact, all you need to know to get you started on your aluminium aircraft project. These subjects will be covered by description, demonstration, and practice as you construct a Van’s toolbox kit. We will also discuss workshop practice and safety, the technical rationale behind many common build techniques, such as de-burring and priming, and provide guidance on further tools and techniques required. Aluminium is a clean material and no special clothes are required, nor will be provided. Overalls, lab coats, etc. are not necessary, but by all means bring them if you wish. Some safety equipment is necessary, however. Please bring suitable eye protection (glasses, goggles), ear protection (muffs, plugs), and hand protection (gloves). All the tools required to assemble the box will be provided by the LAA, but if you have your own air drill (PCL air connection) or pneumatic rivet gun then please feel free to bring them along (suitably identified).

< Back Nick Stone appointed as the LAA's Head of Airworthiness 24 Oct 2023 The LAA is pleased to announce the appointment of Nick Stone as the LAA’s Head of Airworthiness. Nick brings a vast wealth of aircraft knowledge as well as a real world understanding of the need for good process and procedure. Having started his career in the Royal Air Force, Nick went on to work in the aerospace industry working in the UK with British Aerospace and Slingsby Aviation at various sites and projects, as an inspector, methods engineer and quality engineer. Nick then moved to the United States at Eastern Airlines in Miami Florida, Learjet in Wichita Kansas and Chihuahua Mexico as inspection/Quality representative of Shorts Aerospace (Bombardier Aerospace). Following a downturn in the British Aerospace industry he then took an opportunity to move into the nuclear industry working in both reprocessing and power generation. Throughout Nick's working life the one constant has been a passion for aviation. Having started as a volunteer at a local aircraft museum at 14, Nick started flying at the age of 16 in gliders and has a private pilot’s licence PPL(A). Prior to becoming an LAA inspector Nick spent many years building, rebuilding, and restoring vintage aircraft, the more unusual the better. “As an LAA inspector I understand the need to move forward and change and adapt to an ever changing but exciting world. Having run my own aircraft restoration company for the last seven years I always felt it is important to understand your customers”. LAA CEO Simon Tilling said, “Nick is a great addition to the LAA staff. I and the rest of the team are looking forward to working with him in the near future” Next Previous

Weight & Balance The subject of Weight and Balance covers at least four distinct procedures: weighing an aircraft, calculating its empty weight and centre of gravity (CG), establishing the worst forward and aft CG loading cases according to an appropriate design code and calculating weights and centres of gravity for an actual flight. This section includes guidance notes on each of these aspects, forms and worked examples (imperial or metric) for recording and calculating empty weight and CG, as well as worst forward and aft CG cases and an Excel based spreadsheet that makes the weight and CG calculations for you. The table on the spreadsheet is set out in the same layout as the Loading Examples tables. This spreadsheet can, of course, also be used for carrying out calculations for an actual flight. Simply input the actual weights of the items to be loaded rather than the standard occupant or maximum fuel and baggage weights. Remember, it is important to check that the CG remains within limits with no usable fuel as well as with the loaded fuel in the tanks, even though it will not be your intention of running the tank dry. The calculator generates two sets of weight and CG values for this purpose. ​ Weight & Balance arrangements for gyroplanes are different to those of aeroplanes and a special type of report is used, unless the manufacturers concerned provides their own special schedule in which case this should be used instead. Before accessing the documents below, please ensure you have read Technical Leaflet 3.16 - Weight and Balance Guidance Notes .

Permit Aircraft Electrics - Advanced Course Price Member - £200, Non-Member - £220 Duration Arrival 09:00. Finish 17:00. < Back About the Course The Basics course covers simple DC theory and concentrates on the practical aspects of installing a basic permit aircraft electrical system. The course explains how to interpret a ‘typical’ permit aircraft electrical systems diagram and for every element, explains how to size, select and source components and then how to practically install them. This Advanced course builds on the Basics course by providing more detail about component selection and options and the use of integrated power management systems within permit aircraft. The course takes the simple systems design introduced in the Basics course and explores options for creating more complex electrical systems including the use of dual and essential system bus bars. The course introduces fault tolerant design considerations, thus allowing attendees to consider safety and fault analysis in their own designs. As a tool for understanding this aspect of the course, it will take an introductory look into the requirements of electrical systems for those wishing to fly their aircraft under IFR. What this course will try to do is: Explain power generation and distribution options in a light aircraft More advanced consisderations into component selection Discuss circuit protection devices and systems Explain failure modes and reliability issues Introduce interference and EMC issues Show correct grounding and screening techniques Provide you with the knowledge to plan an installation and create the necessary documentation Warn about the ‘gotcha’ areas and the things to look out for What the course will not do is: Turn you overnight into an expert Enable you to fault find on an undocumented aircraft installation Delve inside avionics boxes It will be useful, but not essential, for people to have previously attended the Basic course. In order to make the best of this course, if you have not attended the basics course, you will need to understand basic DC theory; Ohms Law and the Power Law. Please note that this course is primarily a classroom based course, as you will already have the practical skills you need, which are covered in the basics course.
