3.2 Literature reviews
A literature review was undertaken to determine the most appropriate algorithms for the calculation of animal physiological parameters and the interaction with aircraft ventilation
systems. The methodology adopted for this component of the project involved: A review of the current state of scientific knowledge in respect to the relevant
physiological factors; Comparison of predictive relationships for physiological factors with those used in the
version 1 of the LATSA software; Identification of suitable ‘animal factor’ algorithms for computing the required values for
physiological factors applicable to all weights, ages and classes of cattle, sheep and goats;
A review of the methodologies currently employed or potentially available for predicting the environmental conditions in aircraft ;
Comparison of predictive relationships for environmental factors with those used in Version 1 of the LATSA software; and
Identification of suitable ‘aircraft ventilation’ algorithms for predicting the values for key environmental variables during level flight in cruise mode.
The key references consulted during this process include the following: Climitization of Animal Houses CIGR, 1992 2002;
EP270.5 Design of Ventilation Systems for Poultry and Livestock Shelters ASAE, 1986; Live Animal Regulations IATA, 2009a;
Nutrient Requirements of Domesticated Ruminants Freer et al., 2007; Perishable Cargo Regulations IATA, 2009b;
SAE AIR1600: Animal environment in cargo holds SAE Aerospace, 2003; and Standards for the Microclimate inside Animal Transport Road Vehicles SCAHAW, 1999.
A more comprehensive bibliography is provided in Section 8 of this report. It should be noted that the International Air Transport Association IATA regulations IATA,
2009a 2009b treat
SAE AIR1600 as the primary reference in these matters. This literature review provided a series of algorithms which are presented and discussed
throughout Section 4 of this report.
