B737 Undifferentiated or Other Model
Flight Crew Air Transport Pilot (ATP)
Aircraft
I have become aware that the current use of iPad Ram mounts in the 737 cockpit; and possibly all [company] aircraft; is in violation of FAA Advisory Circular 20-173. About mounting devices it specifically it states in Section 5; Paragraph a; 'Positioning must not obstruct visual or physical access to aircraft controls and displays; flight crew ingress or egress; or external vision.' It is not possible to secure the current Ram mount in any location that complies with this directive. In fact; I have seen it mounted as high as half way up the window; effectively blocking a major portion of the view out the side window. Even when mounted on the clip board it blocks several inches of downward vision; critical during ground operations in [or] near the gate. Because of this; I consider the current Ram mount installation unsafe and in violation of AC 20-173.
B-737 Captain reported he feels his company's iPad mount does not meet applicable FAA requirements.
