Systems Requirements: How to choose what to stuff in the airplane…

So this is a post that I started working on in May before we forgot about the blog and didn’t post for 4 months hehe.

In late May we finalized ALL of the requirements for the airplane. They included everything from cabin interior, to avionics, to fuel systems, etc. Fortunately we have an excellent team of mentors that we sent all of our requirements to and got a lot of good feedback from.

While I am the first to admit that requirements don’t really make for very exciting reading the team feels that this is a resource that can definitely help other builders. This was also one of the things that brought the most knowledge to the team. Why? Well, to write requirements for something, you really have to UNDERSTAND how something works. Since most of the team does not have a lot of general aviation experience it involved a lot of research, a lot of questions, and a lot of learning. By the end of the requirements process each member had a much better understanding of how their system was supposed to work and all of the elements of that system. I have attached the summary of requirements as the Microsoft Excel file which anyone can feel free to download and use when building their own aircraft.

Glasair Design Requirements and Objectives

By now we already have completed our preliminary design but that will be the subject of the NEXT post!


  1. […] you look back to the DR&O post you will see that the DR&Os call for wingtip lighting, a heated pitot system, fuel probes, and […]

  2. […] you look back to the DRO post you will see that the DROs call for wingtip lighting, a heated pitot system, fuel probes, and a […]

  3. […] Choosing the systems was a customer-driven process. Would BEFA like an airplane that can only be flown during the day in good weather? Would they find it worthwhile to have an airplane that can fly itself in zero visibility? The team worked with BEFA to draw up requirements, and to select systems components and instrumentation to meet these requirements. This way, BEFA gets the capability it needs without extra bells or whistles. […]
