Is it possible to land without using the flaps at all? Just a

Yes. The plane touches down at a higher rate of speed and, consequently, takes
more runway to stop. In my aircraft, for example, I will touch down at about 60
mph with 0 degrees of flaps and 45 mph with 40 degrees of flaps.

Some airliners would risk tire failure if they landed without flaps.
