I cannot safely fly the 737 with the new [iPad Mount] tray installed. At my normal sitting height; my normal arm position has my left forearm (from the Captain's seat) sitting just below the base of the [iPad Mount] and my normal flying arm movement is totally blocked from any upward movement of the control yoke (i.e.; right turns). It doesn't matter if I have the armrests down or up; as my arm usually is off the armrest when I'm hand flying.At this time; to safely and legally fly the airplane; I have to remove the [iPad Mount] and use paper charts. If the paper charts are removed in the future; I will no longer be able to safely and legally fly this aircraft; as I cannot hand fly with my left arm (from the Captain's seat) without my arm being blocked by the [iPad Mount] mount.Leaving the mount on for the First Officer's legs; my arm also was rubbing against the mount while taxiing the aircraft using Nose Wheel Steering. Although not blocked or overly unsafe; it was an annoyance.I'm by far not the broadest shouldered pilot flying this aircraft; so I imagine others are having this problem too. On my first leg with the [iPad Mount]; my First Officer's arm also annoyingly rubbed against it with his normal flying arm position. Not blocked like mine; but still noticeable and annoying.With the Ram Mounts; at least you were able to move them to different positions depending on pilot preference. While it's nice to be able to now close the sun shade without the suction cups blocking them; the trade off in my case is far from acceptable. With the [iPad Mount] as installed; my only option; other than removing them; would be to totally change how I have flown aircraft for many years; including sitting much further back; sitting higher or lower and flying with a fully extended straightened arm; vice the comfortable bend that most pilots usually fly with. This isn't an option as I don't feel it's a proper position to safely fly the aircraft from.
B737 pilot could not fly the aircraft with new mounting equipment for the iPad.
