Terms & Conditions

Preflight Briefing is a personal pre-flight briefing workflow tool designed to help organise flight preparation, source material, calculations, uploaded briefing images, NOTAM notes, weather review, aircraft status, mass and balance, performance information, timing information, and threat and error management.

The tool is intended to support briefing organisation only. It does not make operational decisions for you.

Preflight Briefing is independently designed and developed by Caleb Ellis.

Unless expressly stated otherwise, it is not an official Skyborne Aviation Academy product, system, publication, procedure, approved training document, or operational tool.

Any reference to Skyborne, Skyborne procedures, Skyborne training context, or Skyborne-style briefing workflows is intended only to describe the training environment for which the tool was originally created.

This tool is a briefing aid only.

It does not replace official Skyborne procedures, aircraft manuals, approved checklists, aircraft documents, operational manuals, NOTAM briefings, weather briefings, instructor guidance, air traffic control instructions, regulatory requirements, approved flight-planning software, or pilot-in-command judgement.

You remain responsible for checking all information against official and authoritative sources before flight.

You are responsible for:

• verifying all information entered into the tool;
• checking weather, NOTAMs, performance, mass and balance, aircraft status, and aircraft documents against official sources;
• ensuring calculations are correct and appropriate for the flight;
• complying with applicable procedures, regulations, and instructor guidance;
• deciding whether a flight is safe, lawful, and suitable to continue.

You should not rely on this tool as the sole source of flight-planning or briefing information.

Any calculators, wind checks, V-speed outputs, map pins, coordinate parsing, timing displays, ETD countdowns, or performance-related outputs are provided as briefing aids only.

They may contain errors, omissions, incorrect assumptions, input mistakes, or technical limitations.

You must verify all calculated outputs against official documents, approved procedures, aircraft data, and instructor guidance before using them operationally.

The tool may allow you to upload or attach briefing material such as weather chart screenshots, mass and balance images, performance screenshots, climb-gradient working screenshots, and NOTAM PIB PDFs.

Uploaded material is intended for your own briefing reference only.

You are responsible for ensuring that any material you upload is accurate, current, relevant, lawful, and permitted to be used for your briefing.

The normal Save function stores briefing data locally in your browser.

This may include text entries, selected statuses, settings, uploaded images, uploaded NOTAM PIB files, and other briefing information.

Local browser storage is device- and browser-specific. If you clear browser storage, use a different browser, use a different device, or local storage becomes unavailable, your locally saved briefing data may be lost.

The tool may provide optional Cloud Sync functionality.

Cloud Sync allows you to generate a secure sync link or QR code, save the active briefing to temporary cloud storage, and load that briefing on another device.

Cloud Sync is separate from the normal local Save function.

Save stores data locally in your browser.

Save to Cloud uploads the current briefing to temporary cloud storage.

Cloud Sync may store briefing data, settings, status selections, section preferences, and supported uploaded files.

Supported synced files may include NOTAM PIB PDFs, F215/F214 weather chart images, mass and balance images, performance images, and climb-gradient evidence.

Cloud Sync is accountless. Access is controlled by a sync link or token rather than a username and password.

Anyone with a valid sync link may be able to access the temporary cloud briefing until it expires or is deleted. You should treat sync links as sensitive and should not share them unless you want the recipient to access the briefing.

Cloud copies are intended as short-lived handover or backup copies, not permanent document storage. Cloud copies may expire automatically and may also be deleted manually using Delete Cloud Copy or End Sync Session where available.

Deleting a cloud copy does not delete local browser copies of the briefing.

The tool may allow you to send a sync link by email.

Email sync links are intended as a convenience and backup method for opening a temporary cloud briefing on another device.

An emailed sync link may allow anyone with access to that email or link to open the temporary cloud briefing until it expires or is deleted.

If an email does not arrive, you should check your spam or junk folder or use the QR code or copy-link option instead.

The email function does not replace Save to Cloud. The briefing must be saved to cloud before the emailed link can load the latest cloud copy.

The tool may use third-party services to provide hosting, storage, database, email, domain, or deployment functionality.

These services may include Vercel, Supabase, Resend, Namecheap, or other providers.

The tool may also include links to external briefing resources such as MAVIS Weather, FlightLogger, ForeFlight, NOTAM resources, or other aviation services.

External services are operated by third parties. Preflight Briefing is not responsible for the availability, accuracy, content, policies, security, or behaviour of external websites or services.

You should use official sources directly where required.

If you use the Contact page, the form may open an email draft addressed to preflightbrieftool@gmail.com.

You can review the message before sending it.

If you send an email, your name, email address, message content, and any information you include will be received by the support inbox for the purpose of responding to feedback, issues, or suggestions.

Do not include sensitive personal information unless necessary.

The Export PDF function is intended to help create a briefing record from the information currently entered into the tool.

You are responsible for reviewing the exported PDF and confirming that it is accurate, complete, readable, and suitable for its intended use.

PDF export may not capture every item exactly as displayed on screen. You should check uploaded images, notes, calculations, hidden sections, and formatting before relying on the PDF.

The tool may allow you to customise appearance, section visibility, section order, default values, briefing mode, sidebar behaviour, and other preferences.

Customisation is provided for convenience only.

Hidden sections may not be counted in the overall briefing status and may not appear in exported documents. You are responsible for ensuring that all required briefing areas are completed and reviewed, whether or not they are visible in the tool.

Preflight Briefing, including its layout, workflow, wording, interface design, and custom briefing logic, is designed and developed by Caleb Ellis unless otherwise stated.

You may use the tool for personal briefing and training preparation.

You may not copy, redistribute, resell, commercialise, or present the tool as your own work without permission.

The tool may be changed, updated, interrupted, restricted, or withdrawn at any time.

Features may be added, removed, modified, renamed, or temporarily unavailable.

No guarantee is made that the tool will always be available, error-free, secure, compatible with every browser or device, or suitable for any particular operational use.

Although the tool includes local save and optional Cloud Sync functionality, no guarantee is made that briefing data, uploaded files, cloud copies, sync links, or exported PDFs will always be retained or recoverable.

You are responsible for keeping any records, exports, screenshots, official documents, or backups required for your own training, operational, or administrative purposes.

This tool is provided “as is” and without warranty.

No guarantee is made that the tool is accurate, complete, current, suitable for a particular flight, compliant with any specific operational requirement, secure from interruption, or free from errors.

To the fullest extent permitted by law, Caleb Ellis is not liable for any loss, damage, operational consequence, training consequence, data loss, missed briefing item, incorrect calculation, delay, or other issue arising from use of, or reliance on, this tool.

Nothing in these Terms & Conditions limits liability where it would be unlawful to do so.

These Terms & Conditions are intended to be governed by the laws of England and Wales, unless a different law is required to apply.
