Hi Freinds,
Recently, I came across a new Free App for A320, a 360 walk around. It's interesting and will be helpful for pilots because the app features the simulation of aircraft exterior inspection procedures.
The company Navcon Aerospace develops such a great app for engineers and pilots. Check out their facebook page for more details.
I'm sharing the link below, hope it helps.
