RVSM Certification

If you are looking to take advantage of reduced vertical seperation distances by certifying your avionics suite, we can help. This certification requires flight testing of your aircraft and avionics, and we specialize in this type of flight testing. FRI has a Barfield tester which enables us to perform all the ground calibrations required prior to the flight test, which is then performed using our own specially designed and built trailing cone flight test equipment. We have experience certifying aircraft ranging from corporate jets to Douglas DC-8s.

RVSM flight testing can be done at our facilities in Mojave, California or at the customer's facilities anywhere in the world. In Mojave, modification of the aircraft is often made easier because of immediate access to all equipment, tools and parts required to install the trailing cone on the aircraft. Calibration of the cone in Mojave is done using the "tower-fly-by" method.

If the flight test is performed at the customer’s facility, FRI ships all the necessary equipment to the customer’s facility and performs modification of the aircraft on site. Arrangement can be made to have the aircraft weighed on location. In the absence of a calibrated tower, the trailing cone is calibrated using a portable ground pressure transducer.




  • Trailing Cone Fabrication
  • Aircraft Modification
  • Aircraft Conformity Inspection
  • Weight and Balance
  • Ground Calibrations
  • Full RVSM Flight Envelope Flight Test



  • The average turn-around time for this type of certification flight testing is three days, with the following milestone schedule:

    Day 1:

  • Modify the aircraft and install the trailing cone
  • Conformity inspection
  • Place the aircraft in "Experimental" category
  • Day 2:

  • Calibrate the cone
  • Perform flight test for full envelope RVSM certification
  • Day 3:

  • De-modify the aircraft, removing the test equipment
  • Return the aircraft to "Normal" category
