Motion sickness consequences of flying closed cockpit aircraft

Flying closed cockpit is in fact flying under Instrument Meteorological Conditions (IMC). The Head Down Display (HDD) and the head Up Display (HUD) offer enough information to allow safe flying. But fast maneuvering in military aircraft under these conditions would increase the chance on disorientation. A Head Mounted Display (HMD) would be...

Finger cold-induced vasodilatation during hypothermia, hyperthermia and at thermoneutrality

BACKGROUND: Exposure of the fingers to severe cold leads to cold-induced vasodilation (CIVD). The influence of ambient temperature on the CIVD-response is well understood and documented, but the response of CIVD to hyperthermia and mild hypothermia has rarely been investigated. METHODS: To investigate the influence of body thermal status on the...

Perspective information in the cockpit to improve situational awareness

Three simulator experiments were carried out to quantify the potential benefits of perspective visual displays in the cockpit for situational awareness support of the pilot, in local guidance and global awareness tasks. In the first experiment, the application of an egocentric perspective display was investigated. Pilots had to perform a wingman...

Decomposition and flame structure of hydrazinium nitroformate

The decomposition of hydrazinium nitroformate (HNF) was studied in a hot quartz cell and by dropping small amounts of HNF on a hot plate. The species formed during the decomposition were identified by ultraviolet-visible absorption experiments. These experiments reveal that first HONO is formed. The HONO formation is followed by formation of NO2...

Cockpit management: Beware of task forgetting even at moderate workloads

Task forgetting is the failure to do a task in time. Disaster may, or may not, ensue depending on the criticality of the task that is forgotten. Poor task (situation) awareness is a necessary precursor of task forgetting. A simulated process-control task consisting of a permanent and an incidental task is introduced as a vehicle to study...

Perspective and predictive information in the cockpit as a target acquisition aid

In two flight simulation experiments, the potential benefits of 3D perspective) radar displays for situational awareness support were investigated. In the experimental set-up, a target acquisition task was employed in which subjects, flying a fighter aircraft, were required to locate a target that suddenly appeared. Then, a target interception...

Visual support for the control of unmanned platforms

There may be various possibilities that may help to overcome the inherent human factors problems in remote control situations that result in degraded situation awareness. The present paper presents two studies focussing on relatively simple image augmentation solutions. In these studies operators of a camera of a simulated unmanned air vehicle,...

3-D-oppervlakte antropometrie : een nieuwe techniek om lichaamsafmetingen te bepalen [3-D surface anthropometry: accurate determination of body dimensions]

Body dimensions of the user population are the starting point of design and evaluation of many workplaces and products. Insufficient attention to these aspects may lead to uncomfortable, unhealthy, or dangerous situations. Recently, Dutch military flying crews have been measured, showing that the body-dimensions of the crews are dramati-cally...

Medical incidences during centrifuge training and F-16 flying in the Netherlands

A survey in the NAMC database containing the records of centrifuge runs of candidate and experienced pilots revealed that in 15.1% of the centrifuge training sessions, a run was stopped. The major reasons were motion sickness (31%), fatigue (28%), and arrhythmias (22%). During centrifuge training at the NAMC the prevalence of an episode of supra...

Loss of performance due to IPE, what's known

In a literature survey the effects of wearing CW protective clothing on performance are structured on basis of a proposed scheme. In this scheme the effects of five types of stress, due to wearing of the CW protective clothing are quantified on three levels of military performance i.e. individual, crew and tactical performance. It is concluded...
