Is it possible for the performance of the anti-skid system to degrade over time, and is there a means by which its functionality can be continuously monitored?
Are 'PFD' and 'EADI' abbreviations for the same instrument, and are they used interchangeably? I did not come across the term 'PFD' in either the training manual or the description section of the aircraft maintenance manual. However, in the document I attached to the email I recently sent, it appears the two terms are used interchangeably.
