HALO/HAHO Parachutist Oxygen Equipment
The newest generation of the HALO/HAHO equipment consists of a portable,
aircraft-mounted console with hoses and a man-mounted bailout system.
The console is designed to supply six jumpers with 100% oxygen to prevent
hypoxia when they are exposed to a cabin altitude above 10,000 feet.
The console's oxygen may also be used for prebreathing, denitrogenation,
or preoxygenation. The personal oxygen system supplies the jumper with
oxygen when the cabin altitude is above 10,000 feet, and the jumper is not
connected to the console. This configuration provides mobility within the
aircraft and oxygen when in free-fall and under canopy. The system provides
either diluted oxygen or 100% oxygen.
Systems components include:
|
|
Portable Oxygen Console
- Six outlets with positive lock female hose connections
- On-off valve
- Tie-down anchors that secure the console to any aircraft
- Pressure reducer gage
- Inlet to reducer allows the aircraft oxygen supply to flow to users while retaining oxygen in the cylinders for future use
|
|
Console Oxygen Hose
- Standard length is 98 inches, but can be supplied in other lengths
- Connects to console with positive lock male connector
- Other end can be fitted with a regulator and low pressure hose or a quick disconnect
The quick disconnect adapts to the jumper's bailout
system hose, which in turn, is connected to a Parachutist Oxygen Regulator (POR)
- An integral flow indicator is available
|
Personal Oxygen System
- Lightweight oxygen cylinders (twin-22 cubic inch or twin-50 cubic inch) and pressure reducer with gage, pressure relief, fill valve, and on/off toggle
- Hose, 19 or 36 inches, connects twin-50 to the regulator
- Optional on/off valve provides convenient control of the oxygen flow by the jumper

Parachutist Oxygen Regulator
- The parachutist oxygen regulator, originally developed for use on the
U-2 during lower altitude training missions, is a 100% oxygen regulator
and includes a combined relief/anti-suffocation valve. Its
operating altitude ceiling is 40,000 feet with a flow up to 180 slpm.
- Inhalation hose comes from either the left or right side of the oxygen
deliver mask and can be routed over the shoulder. The routing
keeps the mask hose off the chest and away from interference with the
ripcord, pillow, or reserve ripcord. The mask suspension prevents
it from riding up during freefall. The mask hose is
non-crushable. The exhalation valve prevents freezing during cold
operations. The mask seal is available in three sizes.
