THE BATMAN Concept Art Reveals Batsuit Designs, Wingsuit, And Closer Look At The Dark Knight's Grapnel Gun

Should’ve got the gliding cape. How the wing suit worked doesn’t make much sense so why not just have him use the bat winged-shaped glider at that point.

The gadgets that Batman utilizes are problematic at best. Reeves Dark Knight utilizes a grappling gun that ejects from his wrist guards. Based on this design that means the rope spools from somewhere in his costume which seems unfeasible given that the cord which would measure 50 to 100 feet or more would have to unspool at a hyper speed seering whatever it is touching which in this case would be Pattinson’s arm.

In addition, Pattinson uses a wing suit to glide off the tops of buildings. This is in contrast to the Christopher Nolan (and even Tim Burton) heroes that utlized their capes as a make shift gliding wing. Accepting the physics of all of these gliding methods, Bale and Keaton’s version would function like a hang glider. Pattinson’s, on the other hand functioned like any standard wingsuit. Therein lies the problem! While hang gliders can coast in for a safe landing, a wingsuit has to deploy their parachutes and float the rest of the way to the ground -- they simply can't reduce their speed fast enough for a safe landing without the use of a chute.

...making Pattinson;s suit a danger to himself as was demonstrated in the film. The use of these gadgets call into question why an engineering “genius” would use these devices.

This is supposed to be the best iteration of Batman?

I get the practicality of the wingsuit but it looked doofy.
