Our exceptional Engineering Department has been working  hard for many years to introduce some of our most prized manufactured items that will relieve aircraft support crews to easily test aircrafts for the current FAA regulations pertaining to RVSM Pitot/Static Inspections (F.A.R. 91.411).  We manufacture RVSM Pitot/Static Air Data Test Sets: the DPST-9200A, a fully automated touch-screen version and the DPST-8000M, a manual touch-screen version.  We also offer Non-RVSM test sets: the DPST-7200A, has the fully automated touch-screen and the DPST-5000M, is the manual touch-screen version.  In 2013 we introduced the DPST-9300A, a 3-channel system, and will soon be unveiling the  and the DPST-9400, a 4-channel system.

Another of DFW Instruments manufactured items is the well known Universal Pitot Static Adapter System ZSAY-3, with pivoting legs and suction cups to accommodate various types of aircraft and helicopters.  In addition, we have an emergency battery back option offering 8-16 hours continuous battery run time. This system provides emergency battery backup protection, as well as being completely mobile and portable for line service use.

One more addition to our manufactured items is the Pitot/Static Isolation Manifold or PSIM-104. It saves time and effort in performing multiple system Air Data Leak Tests, and increasing aircraft availability by reducing maintenance costs.  Each pitot-static channel can also be quickly isolated via quick turn (1/4) shut off valves to allow independent isolation of specific air data systems. 

Feel free to contact us via telephone, e-mail or in person to answer any of your questions that you may have.  If you have a specific requirement that needs to be addressed, we can help you with those requests in a timely, sensitive manner.
