To what end? Does LCH have to be a sleek high speed machine? As it is it’s the fastest (along with Apache and Chinook) helicopters in the IAF’s inventory.
besides fixed LG like that offer more crash protection/survivability which I would take any day over a few more KMPH if top Speed or ‘nicer’ aesthetics
Skids offer more crash survivability than hydraulic or pneumatic or combined apparatus.
As you would notice, light class aircraft often are designed with skid type landing gear. That saves weight and allows the helicopter to land in unprepared areas, more so for military type.
The larger the aircraft, design philosophy tends towards wheel type landing gear.
Uses - towing becomes easy, taxiing from their bays on wheels is easy for heavy helicopters rather than air taxiing. The downwash may topple any other helicopters parked in adjacent bays. If a heavy helicopter is to do air taxy, the dispersal area should be bigger and space between parking bays will have to be increased.
