About Clear Stack Enterprises
Clear Stack Enterprises, LLC is a software company focused on useful, understandable tools. We develop products that bring relevant information into a clear workflow and help people know what to review next.
One focused product: Clear2Fly
Clear2Fly is our mobile product for medication identification and aviation-focused medication review. It is designed for pilots who want to organize information before discussing questions with qualified professionals.
Our product
Clear2Fly helps pilots prepare for an informed conversation.
Medication names and labels can be difficult to navigate. Clear2Fly brings identification, reference information, and a separate flight assessment into one mobile workflow.
Identify a medication
Users can look up a product using its barcode, enter an NDC number, capture label text, or type medication details. The app asks users to review and confirm product matches.
Review relevant information
Clear2Fly presents medication details and label information alongside aviation-focused assessment results and supporting context when available.
Keep useful records
Signed-in users can revisit saved medication lookups and assessments in their history. Assessment settings include an option not to store newly entered medication events.
See uncertainty
When information is incomplete or a reviewed rule is unavailable, the app is designed to show that limitation for further review instead of treating missing information as approval.
How the product works
A clear path from identification to review.
Clear2Fly separates finding a medication from considering its relevance to a planned flight.
Find the product
Start with a barcode, an NDC, a package label, or manual entry. Check the identified product details against the package.
Add flight context
For a flight assessment, review recently used medications and provide a planned departure time where relevant. Some assessment context is temporary and is not saved as a departure itinerary.
Review the result
Read the assessment, its evidence category, and any cautions or unresolved information. Use the result as a prompt for verification and professional discussion.
Safety and responsibility
Information to support review, not grant clearance.
Clear2Fly is an informational screening and decision-support product. It does not replace the judgment of a pilot, Aviation Medical Examiner, healthcare professional, or aviation authority.
No authorization to fly
An app result is not an FAA decision, medical certification, or authorization to operate an aircraft. Pilots remain responsible for determining their fitness for flight and following applicable requirements.
Verify information
Medication identification and available source information can be incomplete or incorrect. Users should check product details against original packaging and verify current information with official sources and qualified professionals.
Conservative handling of gaps
The assessment is designed to distinguish reviewed guidance from label cautions, reported concerns, and insufficient information. An absent match does not mean a medication is approved or safe for flight.
Not comprehensive clinical advice
The product is focused on aviation-related medication review. It is not a diagnostic tool, a substitute for care, or a comprehensive clinical interaction checker.
If you have a question about a medication or your fitness to fly, consult an Aviation Medical Examiner or qualified healthcare professional and follow current official aviation guidance.
