Avgas UL91 & UL94 UL91 has been supplied at many airfields for a number of years. UL94 (similar to UL91 but with a slightly higher octane rating) is now becoming available. These fuels are suitable, and approved, for a wide range of engines types used in LAA aircraft. With 100LL being phased out over the coming years, now is an ideal time to see if your engine is compatible and help do your bit for the environment. The LAA Airworthiness Approval Note (AAN) for use of UL91 & UL94 in appropriate LAA aircraft can be found here . It contains a list of the most popular types of engines for which the fuel is suitable. The EASA document pertaining to use of UL91 in non LAA types is available here.

< Back New LAA Inspector - Paul Armstrong 16 Jul 2025 We are pleased to welcome Paul Armstrong as a new LAA Inspector, having attended an LAA Inspector Assessment Day at Turweston recently. Paul started flying gliders at the age of 15, later progressing to TMG and then to light aeroplanes about 20 years ago. Maintaining aircraft as a part of his hobby is now an integral part of a love of aviation that is approaching its 50th year. Next Previous

< Back The New Permit Revalidation System - Step-by-Step Guide 9 Apr 2025 The new LAA Permit to Fly revalidation system will go live on 15th April 2025. This streamlined, fully online process offers an easier and faster way for aircraft Owners and Inspectors to handle Permit to Fly revalidations. Watch this video for a step-by-step guide on how to complete the online Permit Revalidation process, both as an Owner and as an Inspector. There are a few key considerations to ensure your revalidation under the new system goes smoothly: Please make sure you know your username and password before applying for your aircraft’s revalidation. If you have forgotten your login details, please contact the LAA Office. All aircraft using the new system for the first time will require a check flight no older than 3 months at the time you submit the revalidation application. This is in order to provide a baseline for the online system. The 3-year check flight schedule will then apply subsequently to most aircraft types. Some aircraft will still require a check flight at every revalidation, these are: Aircraft cleared for glider tugging in their Operating Limitations document. Aircraft cleared for Night/IFR. Aircraft which have flown less than 12 hours since the previous revalidation inspection. You will not have to submit your CFS-1 Check Flight Schedule when applying through the new system. However, a CFS-1 will need to be completed for each check flight and stored with the aircraft’s documentation, so that it is available when needed. We encourage you submit your revalidation application through the new online system, as processing time is expected to be faster than an ‘old-style’ revalidation. If you still wish to make an ‘old-style’ application up until 15th May 2025, all 3 forms must be submitted by this date and you will only transition to the 3-year check flight schedule after your first revalidation through the new system. Note: The option to apply for revalidation in ‘My Aircraft Data’ on the LAA website may appear shortly before the go-live date on 15th April 2025 as our IT infrastructure is updated. However, we will only be able to process applications received on or after the official go-live date.

< Back uAVionix AV30E approved as a back-up EFIS 8 Jun 2023 We've recently added the uAvionix AV30E to our list of approved backup EFIS units for use in Permit aircraft. The EFIS units listed in TL3.20 may be used without further reference to LAA Engineering, although your LAA inspector will need to make a Permit Maintenance Release (PMR) entry in the airframe logbook quoting this Technical Leaflet reference.

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 LAA 'Grass Roots Fly-In' returns 23 Apr 2023 The LAA is returning to the green grass of Popham Aerodrome in Hampshire for a repeat of its “Grass Roots Fly In” from 18th to 20th August 2023. The Fly-In will again on one hand take the Associate back to its traditional roots, while continuing to offer the first chance to see some of the latest aircraft and products in the recreational aviation market. What was particularly notable about the 2022 Popham event was its sociality. LAA members and exhibitors alike commented on its relaxed and friendly atmosphere, with post-event comments such as “It’s a great reunion as well as a fly-in–cum trade show” and “super friendly, the event always had a good vibe”. A joint venture with Popham Aerodrome, the LAA Grass Roots Fly In will develop its strengths as a social event bringing flyers from around the UK and Europe to meet fellow enthusiasts. The grass runways at Popham and the airfield’s famed rural ambience will mean that the event will focus on the fly-in and social element as much as on a large exhibition campus. The earlier mid-August date will also mean longer evenings, allowing more scope for flyers from further afield and hopefully, milder conditions for those who choose to ‘camp under the wing’. Said LAA CEO designate Simon Tilling: “The LAA Grass Roots Fly In was a great success last year, with over 3,000 visitors, more than 30 exhibitors and a total of 350 visiting aircraft through the weekend. It is a different event to the past, larger scale LAA Rallies and we’re working on plans for the continuation of a larger scale LAA event in the future. For this year, we’re looking forward to another great, social and fun, LAA fly in”. Next Previous
