Additionally, we can recertify your RVSM (Reduced Vertical Separation Minimums) aircraft and perform skin mapping - waviness inspections. We are also rated to make adjustments to your altimeters and encoders at your aircraft which will save you time and money.

Most turboprop/jet operators accomplish in the ELT, ULB and any aneroid/barometric switch inspection-tests at the same time as the IFR or RVSM inspection. MAG Avionics LLC can perform all those inspections during the same visit.

Furthermore, we use a state of the art digital pitot static test box during our inspections. We can also assist with any troubleshooting that requires simulating altitude and/or airspeed. Examples are autopilot altitude hold problems, elevator feel discrepancies, splits in airspeed or altitude, etc. MAG Avionics LLC specializes in the pitot-static, transponder and altitude reporting systems to assure your aircraft is certified properly and quickly.
