< Back New LAA Inspector - Conrad Ceillam 2 Sept 2025 We are pleased to welcome Conrad Ceillam as a new LAA Inspector, having attended an LAA Inspector Assessment Day at Turweston recently. As a youngster, he worked mostly on 3-engined piston aircraft for commercial flight, and on some twin turboprops in Guernsey. He then moved on to mostly narrow-bodied jets and turboprops, with some executive jets in the UK. Latterly, he worked in Finland on medium-bodied jets, scientific aircraft, and mission/patrol. Since moving to Shetland, he has mostly worked on twin-piston passenger craft. He has held BMAA inspector approvals since April 2023. Next Previous

Permit Aircraft Electrics - Basic Course Price Member - £224, Non-Member - £244 (includes printed course material) Duration Arrival 09:00. Finish 17:00. < Back About the Course This course provides the theory and practical knowledge to enable the implementation of a basic electrical system in permit aircraft. Although the course necessarily includes a small amount of technical theory; it is only included at a level needed (essentially Ohms Law) to understand how wire sizes, fuses, circuit breakers and other components etc are selected. The basic premise of the introductory course is that the owner/builder already has a circuit diagram to work from (few kit manufacturers provide electrical diagrams, so the course includes details of where such ‘standard’ diagrams may be found). They are not expected to do any design work, but they do need to source the materials and components and build a working, reliable and safe installation. 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. The course uses a PowerPoint presentation for the theory side, a demonstration electrical panel in the classroom so that attendees can see the various options and good practice for wiring and systems installation and also runs two practical sessions in the LAA workshop which includes practical soldering, wire stripping and connector crimping, cable marking options, use of heat shrink, radio antenna coax connector installation and the correct crimping and installation of typical D Sub connectors used for avionics systems. What this course will try to do is: Introduce and explain the components of a wiring system Help you understand a circuit diagram Give practical experience in wiring techniques Give the knowledge to select and source cables and components Explain failure modes and reliability issues Help you conduct basic fault finding Warn about the ‘gotcha’ areas and the things to look out for What the course will not do is: Turn you into a design engineer Enable you to design an aircraft EWIS Enable you to fault find on an undocumented aircraft installation Solve interference issues Delve into avionics Your Instructor Mark Castle-Smith Dates Date tbc Times Arrival 09:00.

Preliminary Design Preliminary Design is the stage where the design is sized and developed in outline, leading to a three view drawing, performance and weight predictions. To help with this, LAA has developed a number of spreadsheets. Spreadsheet 1 is used to develop the basic geometry of the proposed aircraft, size the wing, fuselage and tail surfaces and work out some of the key parameters used later. Spreadsheet 2 is used to estimate the performance of the aircraft based on the geometry, initial weight estimates, engine power and guestimates of the drag coefficient and prop efficiency, allowing you to see how the performance is affected by changing each parameter in turn. Spreadsheet 3 is used to work out the critical structural speeds, develop the flight envelope and predict the aerodynamic loads on the main surfaces which can be used to size the structure, and as the basis for a load test program. The weight and balance spreadsheet elsewhere on our website allows the designer to quickly evaluate the implications on weight and cg of different positions for the crew, fuel tanks and baggage bay, and work out what empty aircraft weight and cg he must aim for. Thanks to the simplicity of these programs it takes only minutes to study the implications of changing the aircraft’s specification, for example the effect of changing the wing aspect-ratio, the trade-off between extra weight and cleaning up the airframe drag, extra power etc. Downloadable Spreadsheets Worked Spreadsheet Examples Design Tutorials

< Back New LAA Inspector - Stuart Porter 15 Nov 2024 The LAA is pleased to welcome Stuart Porter as a new LAA Inspector. Stuart attended an Assessment Day at LAA HQ in September.

< Back Mandatory Technical Directive issued for Chipmunk aircraft 24 May 2024 Mandatory Technical Directive, MTD-04-2024 has been issued by our Head of Airworthiness, Nick Stone, today to introduce mandatory recurring inspections of the flap operating cables following a recent potentially serious incident where one of the flap cables on a Chipmunk failed in flight, leading to an asymmetric flap configuration. The MTD allows a 5 flying hour period of grace before the inspection must be carried out and is being emailed today to all owners of LAA Chipmunks and all LAA Inspectors approved to inspect Chipmunks.
