An auxiliary air system contained within the nacelle of a gas turbine engine having the functions of cooling engine components and measuring air inlet temperature. The system comprises an air ducting pipe, temperature sensors extending into the pipe, a structure to be cooled, such as an electronics module, preferably with a heat transfer chamber, an air flow inducer, and, if desired, means for directing air onto other engine components.
