Abstract
A device for use in a leak check test of an air data system includes a device body, an opening extending into the device body with the opening being configured to allow a probe to be at least partially inserted into the opening, and walls surrounding the opening with the walls being situated to seal a port in the probe such that air is prevented from flowing into or out of the port while the probe is inserted into the opening. A method of performing a leak check test includes covering the port with the device to seal the port, heating air within a gas path in the air data system, measuring the change in pressure of the air resulting from an increase in temperature of the air, and determining whether the air data system is sealed depending on the change in pressure of the air.
