Bottenheft, C. (author), Groen, E.L. (author), Mol, D. (author), Valk, P.J.L. (author), Houben, M.M.J. (author), Kingma, B.R.M. (author), van Erp, J.B.F. (author)

This study investigates how cognitive performance is affected by the combination of two stressors that are operationally relevant for helicopter pilots: heat load and hypobaric hypoxia. Fifteen participants were exposed to: 1) no stressors, 2) heat load, 3) hypobaric hypoxia and 4) combined heat load and hypobaric hypoxia. Hypobaric hypoxia (13...

Self-Assessed Preferred Retraining Intervals of Helicopter Underwater Egress Training (HUET)

Bottenheft, C. (author), Oprins, E.A.P.B. (author), Houden, M.M.J. (author), Meeuwsen, T. (author), Valk, P.J.L. (author)

BACKGROUND: Royal Netherlands Air Force (RNLAF) helicopter aircrew get Helicopter Underwater Egress Training (HUET) using a Modular Egress Training Simulator (METS™) in order to be prepared for escaping the aircraft when ditching into water. In the current situation the retraining intervals are only chosen on an arbitrary basis for different...

No effects of successful bidirectional SMR feedback training on objective and subjective sleep in healthy subjects

Binsch, O. (author), Wilschut, E.S. (author), Arns, M. (author), Bottenheft, C. (author), Valk, P.J.L. (author), Vermetten, H.G.J.M. (author)

There is a growing interest in the application of psychophysiological signals in more applied settings. Unidirectional sensory motor rhythm-training (SMR) has demonstrated consistent effects on sleep. In this study the main aim was to analyze to what extent participants could gain voluntary control over sleep-related parameters and secondarily...

Age limitations commercial air transport pilots

Simons, R.M. (author), van Drongelen, A. (author), Toelen, A. (author), Maire, R. (author), Brouwer, O. (author), van Dijk, H. (author), Valk, P.J.L. (author)

The current age limitations for commercial air transport pilots (CAT) required by Regulation (EU) No 1178/2011 were taken over from ICAO Annex 1. For single-pilot CAT operations the limiting threshold is the age of 60 and in multi-pilot CAT operations, pilots can continue to operate until the age of 65. This study aimed to assess the possible...

Hypoxia in a moving base flight simulator - Improving operational realism of a hypoxia training environment

Valk, P.J.L. (author), Ledegang, W.D. (author), van den Oord, M.H.A.H. (author), Steinman, Y. (author)

In a collaborative research project, TNO and the Royal Netherlands Airforce (RNLAF) developed an integrated hypoxia testbed in a moving-base flight simulator. The new hypoxia flight simulator environment aims to improve the operational realism of hypoxia training, and enables research on the effects of hypoxia in relation to flight tasks.

Cognitive performance effects of bilastine 20 mg during 6 hours at 8000 ft cabin altitude

Valk, P.J.L. (author), Simons, M. (author), Jetten, A.M. (author), Valiente, R. (author), Labeaga, L. (author)

INTRODUCTION: Bilastine is a new oral, second generation antihistamine used in the symptomatic treatment of allergic rhinoconjunctivitis and urticaria. It is considered a nonsedating antihistamine and might be recommended for use in pilots, pending research on the effects on flying-related performance under hypobaric conditions that prevail in...

Comparison of three different physiological wristband sensor systems and their applicability for resilience-and work load monitoring

Binsch, O. (author), Wabeke, T.R. (author), Valk, P.J.L. (author)

Leveraging miniaturized sensor and monitoring technology integrated in easy-to-wear wristband wearables represents a great opportunity for advancing Resilience and Mental Health of e.g. employees that experience high workload. Therefore, it is important to gain insights into the reliability of such technology before far reaching conclusions can...

Examining the relationship between mental, physical, and organizational factors associated with attrition during maritime forces training

Binsch, O. (author), Banko, K.M. (author), Veenstra, B.J. (author), Valk, P.J.L. (author)

For infantry units of the Dutch Ministry of Defence, high attrition rates (varying from 42 to 68%) during initial training are a persisting problem. The reasons for this attrition are diverse. Having better insight into the causes of attrition is a prerequisite for implementing preventive measures. To achieve this, a monitoring assessment system...

Effects of a single dose of Bilastine 20mg on flying ability in healthy volunteers under conditions of simulated cabin pressure

Valk, P.J.L. (author), Jetten, A.M. (author), Simons, M. (author)

Background : Optimal physical and mental fitness of pilots is a prerequisite for flight safety. Pilots suffering from allergic rhinoconjuctivitis or other allergic upper airway diseases are not allowed to fly because ambient pressure changes may aggravate the symptoms and some antihistaminic medication may interfere with flight safety, probably...

This report provides an overview of methods to prevent drowsy driving of drivers (Wilschut et al., 2009). Several preventive approaches were discussed such as the use of questionnaires, campaigns and fatigue management plans. A search for law enforcement instruments to prevent sleepiness at the wheel did not provide any instruments that could...
