Checklist · spaceflight participant screening
Educational only · the operator's physician decides fitness to fly1 · Medical history questionnaire — before every suborbital flight [1]
Reviewed by a physician trained or experienced in aerospace medicine. A physical exam and lab tests are not required by the guidance, but are not ruled out.
Conditions to evaluate case by case [1]
Blood pressure medicines (added by SMF) [3][4]
The guidance asks whether a condition could cause an in-flight emergency or death, endanger others, interfere with protective equipment or emergency evacuation, or be harmed by flight. Clearance can be given case by case by the operator's physician [1].
Regulations the operator must meet (14 CFR Part 460) [2]
Part 460 sets no medical standard for participants; the FAA screening guidance is advisory [2][1].

How to use it
Choose the flight profile and the person’s role. The checklist shows the matching items; tick them off and print. Ticks are not saved.
- Suborbital, up to +3 Gz: a medical history questionnaire before every flight, reviewed by a physician trained or experienced in aerospace medicine [1].
- Orbital, or any flight above +3 Gz: a fuller history, a physical exam and tests, valid for 1 year, plus an update 1–2 weeks before each flight [1].
Guidance versus regulation
| Source | Status | What it covers |
|---|---|---|
| FAA DOT/FAA/AM-06/1 (2006) | Advisory guidance for operators | Who to screen, how, and conditions to review case by case [1] |
| 14 CFR Part 460 (CFR) | Federal regulation | Operator duties: written risk disclosure and consent, emergency training, waiver of claims; medical certificate only for crew with safety-critical roles [2] |
Part 460 sets no medical standard for spaceflight participants (SFPs) [2]. Fitness to fly is decided by the operator’s physician.
Acceleration facts from the guidance
- Relaxed, unprotected tolerance of healthy people is about +3 Gz for rapid onset and about +3.5 Gz for gradual onset [1].
- Onset faster than 0.1 G per second is “rapid”; 1.0 G per second or more can cause loss of consciousness without warning [1].
- The guidance assumes the vehicle stays within +4 Gz (−2 Gz), ±4 Gx and ±1 Gy, and a cabin no higher than 8,000 feet equivalent [1].
Limits of this tool
- The FAA guidance dates from 2006 and is advisory. Operators may use stricter or different criteria.
- The guidance’s radiation item (“5 mSv in 5 years”, attributed to the International Commission on Radiological Protection) is consistent with the current ICRP public dose limit: 1 mSv a year, with a higher value allowed in a single year provided the 5-year average does not exceed 1 mSv a year [5].
- Blood pressure medicines are an SMF addition, not part of the FAA guidance: diuretics add to the roughly 15% fall in circulating volume behind landing-day lightheadedness [3], and beta-blockers were the drug class most strongly linked to orthostatic hypotension in randomized trials [4].
