Life Support Equipment
Published in David G. Newman, Flying Fast Jets, 2014
The fast jet pilot must wear specific equipment for self-protection in the aircraft. This equipment usually consists of the flight suit, a flight helmet, an oxygen mask, a G-suit, and a survival vest. In addition, depending on the mission requirements, the fast jet pilot may also need to wear an immersion suit, a liquid cooling garment and/or a chemical, biological, radiological and nuclear (CBRN) protection ensemble. These items of equipment will be briefly discussed in this chapter. The aim is to highlight the complexity of the fast jet operating environment by emphasising the large amount of life support equipment required. This equipment, while protecting the pilot, can also cause additional issues and limitations, such as thermal loading, movement restriction and effects on comfort. To minimise these, aircrew equipment integration is an important process, which in addition to anthropometry will be discussed as well in this chapter.

In Figure 2, the timeline of the protocol during each test day is shown. Upon arrival, the participants received instructions about the test day. At the start of each test day, female participants had to do a pregnancy test, and both male and female participants also had to do a drug test. This was followed by ingesting the capsule with some water for core temperature monitoring. Next, a familiarisation session with the computer tasks was conducted, consisting of three times a 5 min session of the VigTrack, MATB-II, and SYNWIN. Afterwards, the sensors for the SpO2, HR, and skin temperature were attached. Before putting on the Nomex flight suit, vests, and helmet, the participant was allowed to go to the toilet for the last time. These activities together are called the compliance part of the study (see Figure 2).

Resting VO2 was measured prior to donning the ICFP land operational rescue equipment. Participants wore the standardised AV operational land uniform, a two-piece fire-retardant Nomex® flight suit (Sisley Clothing, Maryland, New South Wales, Australia), with the jacket fabric weight 200 grams per square metre (GSM) and pants fabric weight 200 GSM and a cotton undershirt, and sturdy hiking boots (total weight 3.9 kg). The specialised AV land operational rescue equipment consists of a full-body winch harness, winch hook connector, medical backpack, supplementary equipment bag containing rope (a ‘tag-line’) and personal protective equipment for the patient (goggles and helmet), collapsible winch stretcher (Medevac IIA, Lifesaving Systems, Florida, USA), radios, a lifejacket containing signalling equipment and flight helmet. The total weight of all carried equipment was 43.4 kg. The individual weights of this equipment are detailed in previous work (Meadley, Bowles, et al. 2021).
