The utility model discloses a calibration test fixing device for an atmosphere data computer, which is characterized in that two sides of an upper cover plate and a lower cover plate are respectively supported by a right side plate and a left side plate to form a frame structure, at least three groups of slots are symmetrically arranged on opposite surfaces of the right side plate and the left side plate, the slots are horizontally arranged, and one end of each slot is provided with an opening for inserting a support plate; one end of each slot is open, the other end of each slot is sealed, a supporting plate is selectively inserted into each pair of slots, the supporting plates are used for placing an atmosphere data computer, and the atmosphere data computer is connected with external equipment through a test cable. The device can effectively and absolutely safely lock equipment, has enough bearing and protecting capabilities, is matched with a guide rail structure, locks a hardware plate, stably locks the equipment in a test fixing device, supports multi-equipment access test calibration, greatly saves equipment calibration test cost, reduces calibration time, and improves test efficiency. And the space utilization in the testing process can be increased.

The application provides a kind of helicopter L-shaped air speed pipe gas path water accumulation abnormality detection method, belongs to helicopter L-shaped air speed pipe gas path water accumulation abnormality detection field, the method includes: using metal pipeline, constructs air speed pipe gas path, air speed pipe gas path is connected with atmosphere data computer, and metal probe sensor is installed in total pressure gas path and static pressure gas path;Metal probe sensor is connected with atmosphere data computer, and the down pull resistance formed by rain is obtained using metal probe sensor and metal pipeline;Based on the down pull resistance formed by rain, water accumulation abnormality detection is carried out using the signal acquisition circuit of atmosphere data computer, and the air speed pipe gas path water accumulation abnormality detection result is obtained;The application solves the problem that the existing aircraft air speed pipe cannot carry out gas path water accumulation detection.

An aircraft airflow sensor includes one or more pitot inlets, ports, and / or static ports and a calibration data memory physically storing calibration data with the aircraft airflow sensor probe. The aircraft airflow sensor moreover includes where the calibration data is configured to be implemented in an air data computer (ADC).
