Skids are no problem if you have enough Vaseline to coat the runway.

I know a girl who thinks of ghosts
She'll make you breakfast
She'll make you toast
But she don't use butter
And she don't use cheese
She don't use jelly
Or any of these
She uses Vaseline

I just had this mental image of a 1000 ton "tugboat" that makes 1.5G
It goes to orbit, loads 800 tons of Type-A's and such, then back to the surface....and then takes them back to orbit

It could work. As I've noted upthread, as a ship captain, I'd really rather not rely on anyone else to get back out of a gravity well. Maybe in the Imperial Core, but not out on the frontiers.

Strike that. Reverse it.
Out in the frontiers is where a single non-starship operator could enjoy a virtual MONOPOLY on such orbital transfer services to low end 200-400 ton merchant starships with 1G drives needing to land and launch on Size: 8+ worlds out on the fringes. Better yet, you would only need 2G maneuver drives so that surface to orbit trips would only take minutes (loading and unloading would actually take longer than the transit!).

Build a non-starship that can be easily supported by the local in-system technological base ... or a starship that can rotate to a nearby star system every year for overhauls and maintenance ... and you're basically set.

Maybe a thing like drop tanks, but with G-Drives?
Or .... T5 says G-Drives run on built in reactors. Maybe a thing that bolts into the cargo bay?
T5 says a A-Gdrive-12-Ult is 2.25 tons and Mcr1.13. That'd give a Type-A an extra 1G of thrust out to 10D

Drives have to go in the drive bay. Otherwise, nice idea there.
 
This just crossed my mind....
You land you Type-A, no lifters, landing legs with pads, no wheels. It's a 1G world so you can descend as slow as you want, but can't go up. Soft landing isn't an issue.
Once you're landed... you're stuck, which is the whole point of this thread.

But... on an 0.9G or less world, there's gotta be times when there's ships that have engine problems and need to be moved off the landing pad to be worked on?
How do they do that?
A crane would be awkward.
A really, really big forklift? That seems... hard to envision.
What do they do?

I designed a "barge" like that. It was basically a flat rectangle with a driver's cab and some of the machinery in an aerodynamically shaped cabover design at one end. You could load 12 standard shipping containers on it stacked two high. Stack 'em on, clamp 'em down, and you're good to go. No landing gear. It was designed to land on a reasonably flat surface that would support the weight making unloading and loading a snap.
 
In Mongoose One, the rules allowed you to overclock the manoeuvre drive, if only for a turn, relatively safely, so that solved the issue for monomanoevre drives.

In Mongoose Two, this became rather chancy, so not worth trying it, especially midflight.

There might be some obscure option in the Classic books where you could pull that off.

MT did that before MgT.... And MT is more apt to this thread than Mongoose... In that MT is just "Advanced Classic Traveller".. ;)
 
Why would we need to land?

LBB2'77, p8:
INCIDENTALS
_ _ Goods taken on in orbit are delivered when delivered in orbit around the destination. Goods taken on a planetary surface are delivered when off-loaded on the planetary surface of the destination. Similar conditions apply to mail and passengers.
_ _ Shuttles: Where necessary, shuttles operate from planetary surface to orbit and return. The typical cost of shuttle service is 1/100 of the normal interstellar freight or passage cost. Thus, cargo is shipped to orbit by shuttle, or dropped to planetary surface from orbit by shuttle at a cost of CR 10 per ton.

Just ride a shuttle?
 
We already know that.

There may be reasons to land dirtside, with spacecraft that you wouldn't normally consider doing so.
 
In the OTU the most common ACS on the Spinward Main is the type A free trader. Don't you think there would be some mention that every world size 7 or above prevents a type A from landing?
The fact that the type A can operate anywhere on the main and not worry about world size indicates to me that streamlined ships fly, it is really that simple.

Does it specifically say either way? No.
Why would there be shuttles commonly available, if all common ships in the LBB are either streamlined or carries their own smallcraft? There must be some common ships that can't land to pay for the shuttles?

Can they fly in any atmosphere, or lack thereof? Say a freakish high-density size 6 world (say surface gravity 1.1) with atmo 1 (Trace)?

The common merchantmen in the LBBs can only safely operate from type A and B starports (refined fuel). Is that problem specifically discussed in the LBBs? Are merchantmen expected to misjump every year or two?


There is something special about landing on worlds size 8 or bigger (presumably ≥1 G surface gravity):
LBB1'77, p17-18, Ship's Boat skill:
_ _ The Ship’s Boat is carried by large naval vessels, exploratory ships, and some merchants, and is present at many naval bases or outposts. Ship’s Boats are capable of interplanetary flight within a star system, and may lift off from or descend to worlds of size 7 or less. This skill also allows the piloting of shuttles, pinnaces, etc. Only persons with Ship’s Boat expertise are capable of flying such craft.
...
_ _ Emergency landings must be made when landing a crippled ship, when landing on a world of size 8 or greater, or, at times, due to bad weather. Throw 10+ for the ship to be utterly destroyed in the crash. Throw 6+ for the ship to be wrecked. DM: –1 per level. Passengers in the boat each roll for injury, generally their strength or greater to be injured. DM: –1 per level of expertise of the character flying the boat.
Perhaps this is what Infojunky was thinking about in the OP?

Though I struggle to see why a 6 G Ship's Boat would have a problem with a 1 G surface gravity? Perhaps it was intended to be about the 1 G Lifeboat?

Superficial answer: probably, since that's what you're likely riding in, if it's an emergency.

Deeper answer: maybe not, since it's likely about DRAMA! and it's up to the referee to decide what constitutes an "emergency landing". Might even include trying to land after a "small craft drives" hit (one hit destroys that component) as a way to provide a chance of survival even when it shouldn't be possible under the rules as written.
