The service wrappers enforce restrictions on the performance and configuration of data from the service provider. The service wrappers are customized to respective services (such as tracking, terrain, or weather), but provide a standard point of interface, security, and trust between the platform and any services directed to provide a similar function. Upon the request of a user or service providers to obtain aviation data, the UTM platform selects a service providing that aviation data, and provides connection data to the user while protecting the security and integrity of the data. Computationally-intensive tasks that require data from supporting services can be bundled or grouped together as a single service with a service wrapper providing a single point of interface. Bundled services can be designed to as to maintain verifiability and/or safety-criticality of the data passed therethrough. ## Claims ### Claim 1 A method for use in an air traffic management system, the method comprising: communicating, by a server with a plurality of service wrappers respectively associated with a plurality of external services, each service of the plurality of services having a core for providing aviation-related data, wherein the core is encapsulated by the associated service wrapper for providing an interface between the core and the server;
