What are the metal things around the nosewheel and the main landing gear. It also looks like it's on only one main landing gear. Do all MD-80's have these?
I think there are there to keep water/snow from splashing all over the fuselage (see the openings in the back) and to also keep devris from hitting the fuselage. The main wheels hav something similar.
VERY VERY VERY useful!!!
Thanks a lot!!!!
To answer Neil's question... The deflector on the nosewheel is to keep down waterspray, and all MD-80 aircraft have them as do the MD-90 and 717. All earlier DC-9 aircraft were either fitted with chined tires or with the deflector on the nosegear. The deflector was probably better as it also kept down other debris. The waterspray concern was mainly for the engine ingesting it.
You might notice that you saw a spring on the rear of the nose gear strut and that is the ground shift. When the strut fully extends at rotation on takeoff, it places the airplane in an inflight condition so the pressurization outflow valve starts closing and the mast heaters, airfoil anti-ice and various other systems then start to work in the flight mode.
The FOD deflectors on the main gear struts are there to keep debris damage to the flaps and engines from occurring just like on the nose gear.
These photos are very handy for all the little details, aren't they? Many thanks Andrew, well done!
