FAST™ Analysis of Current and Proposed RNZN Watch Keeping Routines

The Fatigue Avoidance Scheduling Tool (FAST™) is a commercially available Windows program based upon the SAFTE applied model originally developed for the United States Air Force.

The program estimates the average effects of a work-rest schedule on human cognitive performance, based on information supplied about an individual’s work and sleep patterns.

The RNZN approached DTA to provide an objective evaluation of current versus alternate watch keeping strategies. Initial analysis revealed a need to mitigate fatigue levels for most watch keepers. By manipulating sleep duration substantial improvements were observed.

Marine Aerosols Reduce Visibility

The Application of MAX-DOAS to Military Environmental Assessment

Dr Jamie Halla suggested designing a passive DOAS that could be mounted on a UAV or aircraft to measure key trace gases and aerosol levels. Aerosols from volcanoes may cause damage to aircraft and sea salt aerosols reduce visibility and may affect the sensor performance of directed energy levels.

Ballistic Technology Development

DTA supports NZDF operations by providing technical advice and testing capabilities. Brian Shaw spoke about the increasing number of enquiries DTA is receiving in the areas of personal protection and terminal effects which has led to the creation of a dedicated ballistics and protection section within DTA.

Coating Applications in the NZDF

Brent Martin spoke about how specialist coatings applications can extend platform capabilities, extend platform life, reduce energy usage, reduce maintenance costs and protect personnel. He explained that DTA’s role is to evaluate commercial products in collaboration with other New Zealand institutions. He then went on to talk about icephobic coatings and DTA’s testing of these in more detail.

NZDF Learner Profiles

James Kerry discussed a survey he carried out of NZDF personnel both uniformed and civilian The study had two objectives. Firstly it attempted to understand how NZDF personnel use technology for training, learning and recreation both at work and at home; secondly it assessed the potential for NZDF personnel to undertake self-directed learning.

He also discussed how NZDF training might benefit from personnel’s willingness to bring their own devices.

Combat Mobility Assessment

Combat Mobility Assessment Dr Graham Fordy from DTA’s Human Systems Group and Asil Khan from Auckland University spoke about the development of a fire and movement activity for accessing soldier combat mobility. The aim was to develop an activity that focussed on both physical and cognitive elements of fire and movement, to capture the data and integrate field assessments and computer data.

Operability Performance Evaluation of Personal Flotation Devices

Andy Richardson, Director of the Human Systems Group spoke about the development of user requirements and performance assessment of personal flotation devices for the New Zealand Defence Force. Andy covered the development of the tests that were conducted and the criteria used. He also looked at operational factors affecting integration of the PFD with New Zealand Defence Force equipment and uniforms.

Image Interoperability

Ian Whaley spoke on the topic of imagery interoperability; the meaning of imagery interoperability, its benefits, and its common pitfalls. He gave an overview of the NATO ISR Interoperability Architecture and the advantages of working within this standards framework. He then presented results from interoperability testing on the GCCS-J system.

Recent Advances in Radio Frequency Performance Modelling

Understanding the performance of sensors in particular radar and communications is essential for developing mission plans as well as quantifying self-protection. Vertical gradients in temperature and humidity determine how radio frequency energy will travel through the environment once transmitted.  If the characteristics of a transmitter is know, it’s performance can be modelled using a variety of environmental data. In this presentation the use of numerical weather prediction is explored and the advances due to model setup presented.
