Cockpit Voice Recorders

We understand the importance of all Cockpit Voice Recorder and FDR readout analysis and have been providing readout services to operators, MROs, Leasing companies and accident investigation organisations worldwide for over 30 years.

Muirhead Avionics offers a readout / replay service for most tape based and solid state / digital Cockpit Voice Recorders checking the functionality of the recorder, intelligibility standards of the recording across all channels and data link correlation.

In addition to routine / scheduled checks we also offer an incident based service and comms checks.

The security of your data is paramount to us and is treated as strictly confidential. Analysis is carried out by our expert Flight Data Readout team in privacy and copies of all recordings are in encrypted format held on a dedicated sever with access limited only to those authorised members. Our reputation for confidentiality has seen Muirhead Avionics handle some of the world’s elite military and Air Accident Investigation Bureau’s flight data readouts.

Downloaded data can be sent to us directly using our AMEfex file exchange system. To register to use AMEfex please click the link at the bottom of this page to create an account. Instructions for use can also be found at the bottom of this page
