Reductions in take-off weight because of reduced lift and, longer take-off and landing distances could have serious implications for the Australian Air Force. A study of 10 Greek airports showed a mean increase in take-off distance of 1.4 m for turboprop and 2.7 m for turbofan aircraft. This may not seem much, but in mountainous countries such as PNG, it might reduce the number of airfields that Australia can use. Reduced payloads would impact support for the Australian Army and Humanitarian and Disaster Assistance (HADR). In defending Australia, our Air Force will have to travel long distances over water therefore, any reduction in capability is a serious issue. Reductions in cargo and passengers could also have economic and health implications for isolated and remote aboriginal communities. Do you think there is a need to factor in a Climate and Environmental Risk Appreciation Process (CEAP) as part of the oint Military Appreciation Process (JMAP)?
