Site Log

While working at USATS as a helicopter CFI, endorsements constantly became a workflow problem.

Most available logbook systems still required handwritten helicopter endorsements or manually edited templates before printing.

Stephane Rebeix, the company’s Chief Flight Instructor, had an internal Excel-based automation tool that solved many of those problems internally. A lot of PilotSeal’s original workflow ideas were influenced by that system.

Because of operational and data security limitations, that tool could not become public.

Toward the end of 2023, I started thinking about building a separate independent version.

• Reduce repetitive typing
• Avoid handwriting endorsements
• Speed up instructor workflow
• Keep the workflow practical during instruction

Started actively learning and building the first local versions.

Everything was rough at this stage.

The site was basically just forms and print output.

The first usable local version started being used during day-to-day instruction.

The workflow was simple:

• Enter instructor information
• Enter student information
• Enter certificate expiration dates
• Generate endorsement text
• Print directly from the browser

PilotSeal officially went online using the original pilotsla.com domain.

At this point, the site was still mostly just an endorsement generator.

Pretty quickly, I started feeling that only having a single endorsement tool was too limited.

The idea slowly shifted toward building a broader aviation workflow website.

Optimized the endorsement generator to support selecting multiple templates at once.

Around the same time, I started experimenting with a Flight Brief system.

The original idea came from an internal workflow we used during instruction. The paper briefing process included:

• Dispatcher information
• PIC briefing information
• Risk assessment
• Operational notes

At the time, the direction of the project was still unclear. A lot of features were partially built, abandoned, rewritten later, or left unfinished.

Around the same period, the open-source EASA Logbook project appeared on GitHub and influenced some ideas around aviation workflow tooling.

Some features were temporarily shut down because I could not realistically sustain server costs at the time.

Development slowed down during this period.

The project was redeployed using Netlify infrastructure.

The domain structure also changed around this time.

For a while, the project lived under tool.pilotseal.com before eventually being merged back into the main PilotSeal structure.

Spent a lot of time improving the endorsement generator for day-to-day usability.

Changes included:

• Better print formatting for physical logbooks
• Online signature support
• More flexible endorsement text extraction
• Cleaner template workflows

Started expanding the site beyond endorsements.

Added and tested tools including:

• METAR / TAF / NOTAM decoder
• Night time calculator
• Weight & balance tools
• Flight Brief workflows

The decoder eventually evolved into interpreting larger blocks of aviation weather and NOTAM text instead of only decoding abbreviations individually.

Flight Brief development also became more serious during this period.

The general workflow became:

• Record flight information
• Pull weather information
• Complete risk assessments
• Generate printable briefing sheets

Development shifted away from standalone tools and more toward workflow integration.

This period included:

• Login functionality
• Saved instructor and student information
• Certificate expiration reminders
• Site-wide notification systems
• Aircraft presets
• Better weather sourcing through AWC
• Embedded weight & balance inside Flight Brief
• Mobile usability improvements
• Large UI redesigns

There was also a long stretch of modifying UI and site structure without a completely clear direction.

Started building a separate project for aviation articles, FAA references, tool explanations, and SEO-related content.

In March, the older React project and the newer Next.js project were merged.

The merge was messy for a while.

The old project had grown organically, so consolidating it into a more structured site took time.

By March 10, the merge was complete.

The site was reorganized into multiple sections instead of a single tool page.

Added user login and internal site notifications.

Added saved certificate expiration reminders.

The endorsement generator became smarter about filling information that previously required manual entry.

Additional updates included:

• Smart NOTAM functionality
• Weather sourcing moved to AWC
• Saved CFI and student profiles
• Saved certificate, medical, and weight information
• Improved weight & balance calculations
• Aircraft presets including C152, PA28, R44, and S300CBi
• Admin-managed site notifications
• Flight Brief integration with weight & balance
• Improved night time calculator display and logic
• Site-wide UI redesign

Improved the decoder system.

Added smarter decoding support for larger METAR, TAF, and NOTAM text blocks.

Removed the old endorsement explanation section and replaced it with a broader Reading section.

Added a Flight Computer section for common aviation calculations.

Updated the signature pad with a flexible mobile layout, allowing users to use the full screen as a signature pad.

Added a reset password function.

Improved the Flight Brief function. Logged-in users with saved weight data can now quickly autofill weight, aircraft type, and other built-in information. Added automatic fuel time calculation and alerts for low remaining MX time.

Improved the endorsement generator print workflow.

This update focused on making generated endorsements easier to print and use as real logbook paperwork.

Changes included:

• Better browser print behavior for generated endorsements
• Cleaner print layout styling
• More reliable endorsement output formatting
• Improved mobile signature and print preparation flow
• Date handling cleanup for endorsement dates
• More consistent date insertion in generated endorsement text

Upgraded the Flight Brief risk assessment workflow.

The risk tool was expanded to more closely match the paper flight risk assessment format, with added static and dynamic risk items, compact scoring, and a tighter layout so the page remains usable without becoming visually crowded.

Aircraft management also received a major update.

Changes included:

• Private aircraft records for users instead of forcing newly added aircraft into the shared registry
• Protection for saved personal aircraft so admin/user accounts do not accidentally share aircraft
• Restored editing for My Aircraft records
• Smaller, denser My Aircraft typography and layout improvements
• Last aircraft information update date shown on saved aircraft
• Personal saved aircraft due tracking for 100hr, Annual, 91.411, 91.413, and ELT
• Month/year due entry with stored due dates normalized to the end of the selected month
• Flight Brief integration with saved aircraft due data
• Automatic 100hr due autofill into Flight Brief MX due when selecting a saved aircraft
• Automatic available / not available / check MX time status based on today's date and current aircraft time

Added Google Analytics tracking so future usage patterns can be reviewed, including page traffic and tool usage trends.

Much of the original workflow design and overall philosophy behind PilotSeal was inspired by internal tools created by Stephane Rebeix during my time instructing at USATS.

John Worth provided a large amount of practical feedback throughout development and helped improve many parts of the workflow and usability of the site.

Nicholas Burleson

Nicholas Burleson was the first real user of PilotSeal outside of my own local workflow testing.

Early feedback, bug reports, and general usage helped validate that the project could be useful beyond personal internal use.
