The potential for small scale local production of Bio fuel derivatives and their partial blending with aviation turbine fuel in non-civilian bases has been investigated. A feasibility study on technical readiness levels for process viability is presented in the paper. Demand side analysis for various blend mixes and corresponding requirement for production facilities and land area requirements are performed. Sustainable production and blending operations are the basis for selection of key performance indicators for the air base. Guiding framework and readiness evaluation processes are delineated for the base. Qualitative inference is combined with quantitative scoring system within the framework.

Ion current sensors have been considered for the feedback electronic control of gasoline and diesel engines and for onboard vehicles powered by both engines, while operating on their conventional cycles or on the HCCI mode. The characteristics of the ion current signal depend on the progression of the combustion process and the properties of the combustion products in each engine. There are large differences in the properties of the combustible mixture, ignition process and combustion in both engines, when they operate on their conventional cycles. In SI engines, the charge is homogeneous with an equivalence ratio close to unity, ignition is initiated by an electric spark and combustion is through a flame propagating from the spark plug into the rest of the charge.

The need to address environmental challenges by aviation industry is apparently obvious. As evidenced within the industry, it takes a three pronged strategy - more efficient aircraft, improving operational efficiencies and development of sustainable biofuels. In terms of actual growth of airline business, the two major drivers are domestic air service expansion within BRIC economies and rapid spread of Low Cost Carrier (LLC) models. Focusing not only on environmental challenges, even sustainable business development and growth of LCC depends critically on ATF substitution by alternative fuels. The inherent need for carbon subsidy and airline-airport partnership towards sustainable substitution with bio-alternatives is discussed in first part of the paper. A framework for such an airline airport win-win partnership is delineated.
