Should you build or buy Aviation Manual Authoring & Distribution?
Aviation manual authoring and distribution software manages an airline or operator's flight operations manuals, links each section to the regulations it satisfies, and pushes updates to crew tablets and electronic flight bags. Airlines, charter operators, and maintenance organizations buy it to keep controlled documents current and provably compliant during an audit.
Buy the authoring and compliance-library platform; building your own EFB distribution app is proven at large carriers, but it does not replace the controlled authoring and regulatory linking that keep the certificate.
Build it, buy it, or bridge?
When building makes sense
Building the distribution layer is proven, but only as an addition to a purchased compliance platform, not a replacement for one. Luxair's own electronic flight bag was built in-house, by a pilot, specifically so it would work the way pilots actually use it, and the airline still relies on Web Manuals for authoring, regulatory linking, and the compliance library underneath that EFB. That's the honest shape of the build case: an airline with engineering capacity can absolutely build a distribution app, a performance calculator, or a mass-and-balance tool tailored to its own crews, and it can be a genuine improvement over a generic vendor viewer. What building doesn't replace is the controlled-document workflow that keeps the underlying manuals linked to current regulations and audit-ready. Treat a custom EFB as a layer on top of a licensed authoring platform.
When buying makes sense
Buying the authoring and compliance platform is the right call for nearly every operator, and the case gets stronger the smaller your engineering team is. Web Manuals, Comply365, and similar platforms maintain a live regulatory library and flag exactly which manual sections a rule change affects, which is the part no operator has good reason to rebuild. Even Luxair, which built its own EFB distribution app, still runs that app on top of Web Manuals for the authoring and compliance work, which shows the two layers aren't the same decision. License the platform for authoring and regulatory linking first. Only consider a custom EFB viewer or distribution app once you have engineering capacity to spare and a specific crew workflow the vendor's own app doesn't support well, and treat that as an extension of the licensed platform.

Frequently asked
Do I need separate software for manual authoring and EFB distribution?
Not necessarily; most vendors, including Web Manuals and Comply365, handle both authoring and distribution to crew tablets in one platform. Some operators still build a custom distribution app on top for a workflow the vendor's own viewer doesn't fit, but the compliance library underneath stays purchased either way.
How do these platforms track regulatory changes?
They maintain a live library linking specific regulatory paragraphs to the manual sections that address them, and alert you when a regulator like EASA or the FAA changes the underlying rule. That linkage is what turns an audit from a manual page-by-page search into a quick lookup.
Can a small operator build its own aviation manual system?
Technically yes, but the harder part isn't the document editor. It's staying current with regulatory changes across every jurisdiction you fly in. Most operators without a dedicated compliance team find that tracking burden alone justifies the subscription, independent of any distribution app they build on top.
What happened with the EASA EFB software regulation in 2019?
EU regulation 2018/1975 shifted EFB approval from covering devices to covering the software running on them, effective July 2019, requiring operators to file for approval under the new standard. It's a reminder that even a self-built EFB has to clear a regulatory bar, not just a usability one.
