ValueKnow Aerospace provides online aerospace-engineering video courses, lesson insights and quizzes at aerospace.valueknow.com. The 15-course yearly plan is $45; the Courses + Industry Guidance programme is $599 (single payment).
You must be at least 18 years old to create an account or make a purchase; by doing so you declare this to be true. You must provide a valid email address and keep your credentials secure. You are responsible for activity under your account. Accounts are personal; sharing access with non-subscribers may lead to suspension.
The 15-course plan costs $45 per year and renews annually on the same date unless cancelled, so your payment method is charged once per year until you cancel. The Courses + Industry Guidance programme costs $599 as a single payment. Payments are processed by Stripe (Stripe Payments Europe for EU customers) under their terms. If we ever change the subscription price, we will give you at least 30 days' notice by email before it applies to your next renewal.
You may cancel the yearly plan at any time from the Billing button on your Account page (Stripe's self-service portal — cancel there or update your card), or by emailing info@valueknow.com; access continues until the end of the paid period and no further charges are taken after it.
14-day right of withdrawal (EU consumers): for your first payment you have the statutory 14-day right of withdrawal from the day of purchase. Because you receive the digital content immediately, at checkout you are asked to consent to immediate execution and to acknowledge that, once you start consuming the content with that consent, you lose this withdrawal right. This does not affect the refund policy below or any statutory rights you keep.
If something is wrong with the service, contact us first — we aim to resolve issues and will refund recent payments where fair. Nothing here limits your statutory consumer rights.
Videos, texts and quizzes are licensed to you for personal, non-commercial learning. Downloading, redistributing, recording or reselling the content is not permitted. Course material is for educational purposes and does not substitute certified aviation training. Lesson notes you write are private to you; do not include other people's personal data in them, and do not upload anything unlawful — we may remove content that breaks this rule.
Who can take part. The community (the forum at /forum/) is open only to members with active access — a paid membership or an invitation from us. It is private: nothing in it is visible to visitors or search engines. If your access ends, you can no longer read or post; what you posted stays visible to members under your display name unless you ask us to anonymise it (see the Privacy Policy).
Community rules. Be respectful and stay broadly on topic (aerospace, the courses, studies and careers). Do not post: spam or advertising; harassment, threats, hate or discrimination; anything illegal or that infringes someone else's rights, including images you do not have the right to share; other people's personal data without their permission; malware or attempts to disrupt the site; or paid course content (videos, guides or documents) from the platform. Do not impersonate others. You are responsible for what you post.
Your content. You keep ownership of what you post. You give us a non-exclusive, royalty-free licence to host, store, display and process it inside the community for as long as it stays there, so other members can read it. Uploaded photos are resized and their metadata (including location) is removed. You can edit or delete your own posts at any time.
Reports and moderation. Any member can report a post. A person (not an automated system) reviews reports and may remove posts, hide threads, lock threads or suspend a member's access to the community when these rules are broken or the law requires it. When we remove your content or suspend your access we email you the decision, the reason and how to contest it. To contest a decision, reply to that email or write to info@valueknow.com; a person will review it and answer you. A community suspension does not affect your courses or the rest of your membership.
Suspended members. While a suspension lasts, the member's posts are hidden from others and threads they started are locked. Hidden content is kept for up to 12 months as a record of the decision, then anonymised; the suspension itself may remain in force.
Invitations. Access by invitation is free and personal: an invitation is for the person it was sent to and may not be passed on. We may withdraw invited access at any time; these Terms apply to invited members in the same way as to paying members.
The service is provided with reasonable skill and care. To the extent permitted by law, we are not liable for indirect or consequential losses. Nothing limits liability for fraud, gross negligence, death or personal injury.
We may update these terms; material changes will be announced on the site and, for subscription price changes, by email at least 30 days in advance. Spanish law applies; EU consumer-protection rules remain unaffected. Consumers may bring proceedings in the courts of their own domicile; otherwise the courts of Barcelona (Spain) apply.
