Aviation/Flying/Retractable mechanism for Landing gear in airplanes.


Dear Ned

Are the Landing gears always retractable in all airplanes ?.


Once the airplanes takes off, the front and rear wheels are always
folded ?.
Once the airplanes wants to Land, the front and rear wheels are unfolded ?.

What are the Pros and Cons with and without having these retractable mechanism for Landing gears in airplanes ?.

Thanks & Regards,
Prashant S Akerkar

When the landing gear is not retracted it provides resistance to the air as the plane moves forward after takeoff. This reduces speed and increases the amount of fuel required to make a trip.

On planes without retractable gear the complexity of the aircraft is reduced making it cheaper to build and maintain.
