Landing Gear

I did abuse my players having the planetary surface covered with a high forest except for a few sandy looking patches that were crunchy domes over large sinkholes. The trees were large and had space enough to land between them on grav thrusters on the Marava class Far Trader. They instead set down on the top of a dome and broke through into the sink hole. The pilot made a difficult roll to flip the grav drive back on before impact keeping the ship light damage and turning the cargo of fresh mellons into a horrible liquid mush.
Never trust an unimproved landing surface on a frontier planet with a E type starport.
The TL1 natives living in the trees were almost friendly when it came to trade after making contact. The mushed mellons they strained into fuel along with the torrential rains. Rolls of large plastic sheets can be useful collecting rain water for fuel. The natives used Zuchai crystals for decorations along with copper jewelry that the engineer used to fix the drives. The crewman scout always kept a half ton of trade goods for just such occasions. TL1 natives like steel blades.
Everything the players thought was bad turned into what they needed to get back into space.
The merchant gained a duty to toss a bowling ball out the hatch from altitude on all landing fields they were not certain of.
 
Nope. My driveway is on top of a bed of quicksand. :coffeesip:

The typical load bearing for compacted soil is between 1000 Pounds per square foot (psf) and 2000 pounds per square foot (based on local soil).

Your concrete slab has a bearing capacity of 3000 pounds per square inch. So the concrete driveway spreads the 4000 pound weight of your large Pickup Truck over a 10’ x 20’ area for a ground pressure on the soil below of only 20 PSF.

The load bearing capacity of uncompacted soil can be as low as 10 PSF (like beach sand).

The point load for your car is equal to the inflation pressure in your tires, so a 30 psi tire applies a 4320 psf concentrated load on the ground. That is why your car can drive on all paved surfaces (12,000 psf load capacity) and most compacted dirt roads (4000+ psf load capacity) but will almost instantly get stuck in sugar sand (10 psf load capacity).

**********

A 200 dTon Free Trader weighs between 800 metric tonnes (1,600,000 pounds) and 2000 metric tonnes (4,000,000 pounds).
If you wanted to land on truck tires, you would need 360 to 890 truck tires per Free Trader to support the weight (at 4,500 pounds per tire).
If you wanted flat landing skids, you would need 134 to 334 square feet of skids to support the ship on a typical roadway without sinking into the ground beneath. That would be 5 to 14 deckplan squares of landing feet.

Enjoy the data.

Yes, you wouldn't design it that way. The skids would just be stabilizers and the ship would rest on its belly
