High Altitude Training


Gain the knowledge and experience to recognize and manage the physiological effects of high altitude with three flights in a hypobaric chamber.


LOCATION: Southampton, Pennsylvania, USA
DURATION: 1 Day (5 hours)
AVAILABILITY: Available now


NASTAR’s high altitude training program consists of 2.5 hours of academic instruction and 3 altitude chamber (hypobaric chamber) training flights, where trainees will practice recovery techniques for hypoxia, hyperventilation, and rapid decompression. The two portions of the program are outlined below. Lunch is provided.

Classroom training

- Gas laws and atmospheric physics
- Physiological divisions of the atmosphere
- Physiology of respiration and circulation
- Effects of health and stress on hypoxia
- Causes and effects of hypoxic, stagnant, hypemic, cytotoxic, and carbon monoxide
- Effects of trapped gas in the human body and clearing techniques
- Effects / prevention / recovery from hypoxia, hyperventilation, hypercapniaTime of useful consciousness (TUC), effective performance time (EPT)
- Effects of hypoxia on night vision, retina, rods & cones. Day and night blind spots, scanning techniques
- Effects of rapid decompression, preventative measures, symptoms, treatment, and hyperbaric chambers
- Oxygen equipment use, inability to equalize, delayed ear block
- Cabin environment, pressurization systems, ETOPS flight planning in the event of a rapid decompression

Altitude chamber flights

- Safety briefing, including flight profiles, equalizing procedures, hypoxia, hyperventilation, and DCS symptoms review
- Equipment familiarization, including CRU-73 regulators, communications, pulse oximeter fit and operation check
- Emergency procedures, including hypoxia / hyperventilation recovery, chamber emergency egress
- Oxygen pre-breathe: 30 minute N2 purge, view safety videosEar and sinus check at 8,000 ft
- Flight #1 (25,000 ft) - hypoxia symptoms recognition and psychomotor skill test
- Flight #2 (18,000 ft) - loss of night vision demonstration
- Flight #3 (2,000 to 12,000 ft in ~3 seconds) - rapid decompression
- CCTV video review
- Post-flight safety review, including decompression sickness symptoms, delayed ear block. Review of safety data card.
- Certificate of training

Note: NASTAR offers suborbital spaceflight training, orbital spaceflight training, and high altitude awareness training. You can participate in these as individual sessions or combine them for a complete experience.


Sponsorship: Sponsor an individual or group experience.


FAA Medical Class 1, 2, or 3 or equivalent for country of citizenship, or physician clearance letter is required.

Trainees are expected to be in good health and capable of taking part in all activities. Trainees must not have colds, flu, allergies, or sinus issues on the date of training.

No beards and goatees. Moustaches are okay.

Refrain from using petroleum-based hair and facial/skin products on the day of training as they pose a hazard in an oxygen environment.
