A system comprising: an air data system comprising: a gas path (34A, 34B, 34C); a probe having ports and a heater, the ports forming an entrance to the gas path (34A, 34B, 34C) and configured to allow air to enter the gas path (34A, 34B, 34C); and a transducer having sensors situated along the gas path (34A, 34B, 34C), characterized in that the system further comprises: a controller configured to instruct the air data system to begin a leak check test and configured to determine if the air data system is absent of leaks; and a device configured to cover at least a portion of the probe during a leak check test of the air data system, the device comprising: a device body; and an opening extending into the device body with the opening being situated to seal the ports in the probe so that air is prevented from flowing into or out of the ports when the probe is inserted into the opening, wherein a leak check test begins when the device is sealing the ports of the probe with the leak check test including instructing the heater to increase the temperature of the air within the gas path (34A, 34B, 34C) and instructing the sensors to measure the change in pressure of the air within the gas path (34A, 34B, 34C) resulting from the change in temperature of the air. an air data system comprising: a gas path (34A, 34B, 34C); a probe having ports and a heater, the ports forming an entrance to the gas path (34A, 34B, 34C) and configured to allow air to enter the gas path (34A, 34B, 34C); and a transducer having sensors situated along the gas path (34A, 34B, 34C), a gas path (34A, 34B, 34C); a probe having ports and a heater, the ports forming an entrance to the gas path (34A, 34B, 34C) and configured to allow air to enter the gas path (34A, 34B, 34C); and entrance to the gas path (34A, 34B, 34C) and configured to allow air to enter the gas path (34A, 34B, 34C); and a transducer having sensors situated along the gas path (34A, 34B, 34C), characterized in that the system further comprises: a controller configured to instruct the air data system to begin a leak check test and configured to determine if the air data system is absent of leaks; and a device configured to cover at least a portion of the probe during a leak check test of the air data system, the device comprising: a device body; and an opening extending into the device body with the opening being situated to seal the ports in the probe so that air is prevented from flowing into or out of the ports when the probe is inserted into the opening, a controller configured to instruct the air data system to begin a leak check test and configured to determine if the air data system is absent of leaks; and a device configured to cover at least a portion of the probe during a leak check test of the air data system, the device comprising: a device body; and an opening extending into the device body with the opening being situated to seal the ports in the probe so that air is prevented from flowing into or out of the ports when the probe is inserted into the opening, wherein a leak check test begins when the device is sealing the ports of the probe with the leak check test including instructing the heater to increase the temperature of the air within the gas path (34A, 34B, 34C) and instructing the sensors to measure the change in pressure of the air within the gas path (34A, 34B, 34C) resulting from the change in temperature of the air.
