Pitot-static air data test system with pilot and co-pilot verification

An air data test set system, comprising:

• at least one pneumatic pump configured to generate pressurized air;
• at least two pairs of impact and static ports configured to direct at least a portion of the pressured air to a pitot-static system;
• a manifold system, in fluid communication with the at least one pneumatic pump and each pair of impact and static ports, the manifold system comprising a plurality of flow control valves configured to direct the pressurized air from the at least one pneumatic pump to the impact and static ports, wherein the manifold system includes a channel for each of the ports and further comprises a plurality of pressure sensors for controlling the pressure in each channel and a plurality of zeroing valves interposing each channel, the zeroing valves being interconnected and configured to be openable to a threshold pressure prior to commencing a data test for the purpose of eliminating drift in the pressure sensors;
• a signal processor operatively coupled to the at least one pneumatic pump and the manifold system, the signal processor configured to:
• (i) issue a commanded air pressure signal indicative of a commanded air pressure associated with each of the impact and static ports, (ii) monitor the air pressure in the manifold system to detect variations therein beyond a prescribed range of air pressure values, and (iii) issuing an air pressure correction signal to the at least one pneumatic pump to maintain the commanded air pressure within the prescribed range of air pressure values;
• and
• a plurality of drop-off valves interposing each channel and disposed immediately upstream of the static and pitot ports and downstream of the zeroing valves configured to manually reduce the applied pressure in the event of a system failure by sequentially opening when power is removed from the ADTS.

An Air Data Test System (ADTS) for testing a pitot-static system, comprising:

• at least one pneumatic pump configured to generate air pressure;
• at least two impact ports configured to direct at least a portion of the air pressure to the pitot ports corresponding to Thea first and a second airspeed instrumentation undergoing the air data test;
• at least two static ports configured to direct at least a portion of the air pressure to the static ports corresponding to the first and second altitude instrumentation undergoing the air data test;
• a manifold system in fluid communication with the at least one pneumatic pump and comprising a plurality of flow control valves configured to simultaneously direct air pressure to both the first and second instruments through each of the impact and static ports, wherein the manifold system includes a channel for each of the ports and further comprises a plurality of pressure sensors for controlling the pressure in each channel and a plurality of zeroing valves interposing each channel, the zeroing valves being interconnected and configured to be openable to a threshold pressure prior to commencing a data test for the purpose of eliminating drift in the pressure sensors;
• a signal processor operatively coupled to the at least one pneumatic pump and the manifold system and configured to simultaneously control the commanded air pressure to each of the impact and static ports to perform simultaneous testing of both the first and second instruments;
• a mobile device connecting to the signal processor to issue command signals indicative of a prescribed air pressure value to simulate an instrumentation values in at least one instrument on under test;
• and
• a plurality of drop-off valves interposing each channel and disposed immediately upstream of the static and pitot ports and downstream of the zeroing valves configured to manually reduce the applied pressure in the event of a system failure by sequentially opening when power is removed from the ADTS.
