Tim R,
The web gremlins have struck again and maybe taking on Tim R will help in keeping the confusion down. On second thought I'll stick with either Tom Rux or Tom R.

Argh! Indefensible, my sins are. In mitigation, your Honour, stands the fact that male humans with stubby fingers were never intended to operate touch-screen phones designed for those of the fairer sex, children, and UI designers with freakishly long, tiny fingers. Me, phone virtual keyboards, typos... a true inevitability.

Mea culpa, sorry, Tom R.
What an interesting defense you have put forth. Since my cell phone and computer do not have virtual keyboards my typos are due to gorilla paws, poor typing skill, and my mind or copying/pasting screwing up the material.

What are  the modifiers for the other starports from B to E or X if given?
My apologies for not including the list.

Traffic DM by Starport type A: +4; B +2; C 0; D -1; E -2. Spaceport Type F: 0, ; G -1; H -2.

Hmm, C to B is +2, I can see A being another +2 because it is a much more capable port generally (in that the presence of shipyards that can do work on starships is presumed in the rules).


It could be the +4 makes sense for a class A and 150% ought to be 160%.

Rationales/Cases:
- trade growth suddenly
- nearby main or key route unavailable
- refugees
- pilgrimage
- no funding to build out
- discovery in system that requires or offers good reason for more merchie traffic
- real airports often require long pattern waits vs immediate landing
- one efficiency for highport : require docking/unloading)undock within 6 hour window, ships undock, deal by comms, dockagain for pickup... Means each pad/bay has 4 slots per day
The text states 0% to 150% is the percentage of berths filled. The instructions indicate that anything of 100% is in orbit and on a waiting list to land at the port. The waiting time in hours is determined by rolling ((2D6-2) x the percentage)/10 rounding fractions up.

Sure, but it could be 0% and 160% with the +2. I think that's the better fix. I think the +2 is more reasonable and I think the 150% needs amended, not the starport modifier being reduced.

They basically said what I kind of pointed out in the list above - like modern airports, when there is no landing pad/dock/whatever, then you are effectively stuck in orbit. That's like an airport holding pattern. And the 100% could be at a high port, could be at both high and low ports combined, or just for a low port if no high port is extant. Regardless of the port architecture (low only, high only, high and low), the 100% would be at the port (however that port is physically distributed). Everyone else is waiting their turn.

Also, looking at your comment on the math:

With a 160% load (and only a 100% capacity...), you have +60% over capacity. So I guess then I roll 2D6-2 (call it average 5) x 60%/10 = 30 hours. So that would be your average hold in the orbital traffic pattern at the major type A port at full 160% capacity. The minimum would be 0 x 60%/10 = 0 hours (meaning you can't land I guess, but you are next up in less than one hour) and the maximum would be 10 x 60%/10 = 60 hours (aka 2.5 days).
Using Excel with the average die roll 5 I entered the equation 5 x 60%. The result I got was 3 / 10 = 0.3 hours. Per the instruction in Complete Starports the 0.3 hours is rounded up to 1 hour.
I know in some commercial ports (and other sorts too, but we're talking about merchant traffic) on our seas, you can have a wait if the port capacity is reached (same for lock/canal passages) and one aspect of that follows with one TMLer's definition of pilot as 'harbour pilot' basically... if you don't have enough harbour pilots to help bring in the bigger vessels (and ships crew MUST be supervised by a harbour pilot, then that's another reason the port can seem at capacity (same effect, you can just treat this as one of the cases of 'port beyond capacity').
I can verify that there where times when my four boats and the tender had time to loiter at sea before being brought into port while waiting for the local pilot to guide us in. The trip into and out of Rosyth, Scotland was a very interesting one.

However, in Timothy's and Alex's AARs the ship's pilot maneuvers the craft into and out of port including landings and take-offs from the downport, achieving orbit/deorbiting, and/or docking/undocking at the highport
So I think the correct fix for the broken math is change the range from "0% to 150%" to "0% to 160%" and maintain the A starport modifier of +4.

Most of the time, when you get a minor overage (+10%), your average wait will be 5 hours, at 20% 10 hours. Those aren't gross in commercial shipping terms.

Something to think about:
One kind of assumes better/more advanced/more feature rich ports --> more capacity in traffic handling.
The math tells us though that A & B class ports are fairly likely to have minor delays (meaning that 'more traffic' EVEN RELATIVE TO the greater traffic handling capacity of the larger ports).
So, an A type Starport will be pulling in *way* more traffic (in gross terms and in terms of its high level of traffic handling).

I'd equate this to flying into Dulles, O'Hare, or La Guardia (Starport A) vs. some other large city ports that don't do the same volume (call these the B level ports). Then C ports could be (for purpose of thinking of traffic levels) be equated to small cities or very large towns local airports. D ports might be medium sized towns. E becomes small town landing strips.

When you fly into a major airport like the above 3 airports I named, if you are from a small airport normally, your head has to be on a swivel (eyes open), you have to keep to the possibly complex approaches, and you have to be also thoroughly tuned in to the comms chatter and be spotting the things they names in the busy airspace around you. Also, if you are not where you need to be or aren't following ATC's direction with alacrity, you can bet you'll be called out ASAP and in very stern terms to do as you are directed. I have had several friends who are ATCs or who work on automated approaches/automated landing systems and they always get irked by the small aircraft pilots that come to the big centers and are 'deer in the headlights' and need stern direction and handholding to avoid causing a hazardous situation.

So, for folks like Tim (the real Tim, not a Tom in disguise) and Alex, who love to mine 'colour' or 'adventure material', the waits in the traffic pattern can become an adventure friction point if the group has a time sensitive cargo (there may be priority queues at some ports too that might let some types of traffic jump the normal traffic patterns). Also it could be 'We have a couple of days in an orbit before we can get a berth to unload... what will we do with that?'. And the stress of flying into large, busy traffic patterns around unfamiliar ports might prompt some ideas of 'events/encounters' in the traffic pattern and some more scary rolls for their pilot, Captain, comms officer, etc. and some fun exchanges with tart ATCs.

To recite an humorous (may have been entirely made up) 'tart ATC' story:

Allegedly the German air controllers at Frankfurt Airport are renowned as a short-tempered lot. They, it is alleged, not only expect one to know one’s gate parking location, but how to get there without any assistance from them. So it was with some amusement that we (a Pan Am 747) listened to the following exchange between Frankfurt ground control and a British Airways 747, call sign Speedbird 206.
Speedbird 206: “Frankfurt, Speedbird 206 clear of active runway.”
Ground: “Speedbird 206. Taxi to gate Alpha One-Seven.” The BA 747 pulled onto the main taxiway and slowed to a stop.
Ground: “Speedbird, do you not know where you are going?”
Speedbird 206: “Stand by, Ground, I’m looking up our gate location now.”
Ground (with quite arrogant impatience): “Speedbird 206, have you not been to Frankfurt before?”
Speedbird 206 (coolly): “Yes, twice in 1944, but it was dark,… and I didn’t land.”

For some possible reasons ATC may not respond quickly that could be Travellerized:

And some humour:
Being an Air Force brat aviation was one of my first interests growing up. I collected all sorts of stories.  When I was stationed on SSBN 610 in the Pacific I flew between Hawaii and Guam four times a year and when I went on leave between Hawaii and Seattle, Washington. When I was transferred to the Atlantic Fleet I flew from Hartford, CT to either Prestwick or Glasgow from there we rode buses to a ferry terminal which took us across to Dunoon and then to the MOD facility where we loaded onto small boats to be taken out to the tender in Holy Loch.




Systems on Starships and Spaceships are all built w same construction systems. Only difference is Jump Drive. So Starship yard can repair Spaceships.
I agree that the difference is the Jump Drive and associated components. One article indicates that a starship's hull plating has a wire grid that distributes energy around the ship. Another thought is the hull plates have plumbing that distributes L-Hyd around the hull.

Spaceship hulls do not need special hull plating to operate.

When you build the ship in any build system I've seen, you purchase hull. There's no particular type of hull and one would think a hull with the grid and the paths for gases would be more expensive, but it is not. Therefore, I assume a) they are the same (based on build system) or b) they aren't, but some amount of variance is papered over (and thus probably would be for repair too).
I have seen the original CT LBB 2 1977 build system which has the following on p. 20 Customer Designed Ships "3. Non-starships may be constructed using the basic rules for starship construction, but omitting the jump drive. They may not later be converted to interstellar capability, but may be produced for 50% of the price of a comparable starship."

I do not recall reading about spaceships in MT, TNE, T4, GT, T20, and MgT being converted to starships by installing a Jump Drive. However, a starship with a unrepairable jump drive becomes a spaceship.

What you clipped says Spaceship yards have  don't automatically get to repair jump drives, but rather there is a test based on a (not reproduced here) table. I believe that aligns with what you understood.
