Abstract: There is provided a method of starting a gas turbine engine, comprising: selecting a baseline starting procedure of the gas turbine engine based on environmental data; receiving condition information for the gas turbine engine and/or for a starting system of the gas turbine engine, the condition information comprising at least one of: health information for the gas turbine engine and/or the starting system; maintenance information for the gas turbine engine and/or the starting system; and operation information relating to an expected future usage of the gas turbine engine. The method further comprises determining a predicted degradation profile for the gas turbine engine and/or the starting system based on the condition information; determining a starting procedure of the gas turbine engine by adapting the baseline starting procedure based on the predicted degradation profile; and controlling the gas turbine engine and/or the starting system according to the determined starting procedure.

Abstract: A method of automating enforcement of a data validation rule associated with an input field by a Model View Controller software application includes applying an input constraint embodying the data validation rule to a Model to generate an applied constraint, discovering the applied constraint via examination of the Model by a View-Controller Generator to generate a discovered constraint, generating an input field constraint mechanism using the discovered constraint, and constraining the input field using the input field constraint mechanism to generate a constrained input field.
