The effects of high altitude on humans are considerable. The oxygen saturation of hemoglobin determines the content of oxygen in blood. After the human body reaches around 2, metres (6, ft) above sea level, the saturation of oxyhemoglobin begins to decrease rapidly. However, the human body has both short-term and long-term adaptations to altitude that allow it to . This paper describes a design process of HALE PW sensor-craft, developed for high altitude (20 km) long endurance (40 h) surveillance missions.

  The advanced Heron TP, which belongs to the Medium Altitude Long Endurance (MALE) class with an endurance of over 36 hours, will be manufactured to cater both to Indian requirements for a combat UAV and possibly exports to third nations in the future as well.

AMS includes two major, life-threatening conditions; high altitude pulmonary oedema (HAPE) and high altitude cerebral oedema (HACE). Treatment for these conditions must be immediate to avoid long-term injury and fatality. The primary treatment for HAPE and HACE is evacuation to lower altitude/sea level as rapidly as possible. Unmanned High-Altitude Long-Endurance (HALE) aircraft have been studied for several years. Reconnaissance, surveillance, search and rescue, drug interdiction, atmospheric sampling, etc. are a few of the potential missions for HALE aircraft. One of the pacing technology items for an aircraft of this type is the propulsion system.

Initial Feasibility Assessment of a High Altitude Long Endurance AirshipCited by: High-Altitude Long Endurance (HALE) is the description of an air-borne vehicle which functions optimally at high-altitude (as high as 60, feet) and is capable of flights which last for considerable periods of time without recourse to landing.

The Tropopause represents high-altitude. Initial Feasibility Assessment of a High Altitude Long Endurance Airship A high altitude solar powered airship provides the ability to carry large payloads to high altitudes and remain on station for extended periods of time.

This study examines the feasibility of this concept. Factors such as time of year, latitude, wind speeds and payload are considered in establishing.

Icarus Aerospace has revealed a clean sheet design for an optionally-piloted armed overwatch and light strike aircraft that can also be adapted into mid/high-altitude long-endurance intelligence.

Research is being carried out at the Turin Polytechnic University with the aim of designing a HAVE/UAV (High Altitude Very-long Endurance/Unmanned Air Vehicle). The vehicle should be able to climb to an altitude of 17–20 km by taking advantage of direct sun radiation and maintaining a level flight; during the night, a fuel cells energy.

Currently, there is a large interest worldwide in the development of High Altitude Long Endurance (HALE) Unmanned Aerial Vehicles (UAVs) for a number of civil and military missions, such as routine weather reconnaissance, surface reconnaissance (forest fires, etc.), earth observation, border patrol and monitoring, fisheries and wildlife refuge management, chemical.
