What is a Tandem Type of Landing Gear Arrangement?
The tandem landing gear is used for very large aircraft like the B-52 bomber and the U-2 reconnaissance/research aircraft. The main landing gear is in two sets that are located one behind the other on the fuselage. It allows the use of a highly flexible wing, but it may also require the use of small wheels on the tips of the wings to keep the wings from scraping the ground.
