Approximately Up Shipbuilding Tools

Theorycrafting a ship in Approximately Up is cheap; crashing it after a twenty-minute wiring session is not. The Tools Hub collects interactive helpers and reference planners you can use before entering fly mode — the same way real engineers sanity-check thrust margins and landing speeds. Tools here complement guides and tier lists: they answer numeric questions while articles explain which parts to bolt on.

Why tools matter in Approximately Up

Distances between Planet Stations are large enough that weak thrust turns a five-minute hop into a fuel-and-patience marathon. Gravity and atmosphere differ per world, so a lander that felt lively on Earth may feel like wet concrete on a high-gravity moon. First-person flight from the deck means you discover problems late unless you plan TWR, approach speeds, and instrument layout ahead of time.

Our tools focus on problems players actually hit in the demo and full release:

• Can this hull lift with these thrusters? → thrust-to-weight ratio.
• Do I have enough vertical thrust for a lunar pulse landing? → TWR with cargo sliders.
• Should I add another atmospheric cluster before leaving Earth? → compare against tier recommendations.

Pair calculators with Thruster tier list and Sensors and logic tier list so numbers and rankings agree.

Featured tool: Thrust calculator

The Thrust calculator estimates thrust-to-weight ratio (TWR) from mass, gravity, and installed thrust. TWR above 1.0 on vertical axis means you can accelerate upward against gravity — essential for Earth takeoff and controlled lunar landings when you pulse electric thrusters.

Use it when:

1. You add cargo for a delivery mission and feel sluggish on the pad.
2. You swap atmospheric clusters for electric and need a vacuum-only check.
3. You co-op with a friend who insists “it’ll fly” — settle it with math before blame game season.

The calculator page explains TWR in plain language and embeds the interactive widget mid-article so you can tweak values while reading.

Planned and future tools

As the wiki grows, this hub may add:

• Route time estimator — distance + average thrust hints between known stations.
• Power budget worksheet — solar vs battery draw for long cruises.
• RCS symmetry checker — conceptual checklist for six-thruster layouts.

Announce new tools on Updates when they ship. Suggest ideas via official Discord — see Links — but expect wiki tools to remain fan-built, not in-game overlays.

How to use tools with guides

Recommended flow for new builders:

1. Read Getting Started for controls and first objectives.
2. Open Thrust calculator with your planned mass and thrusters.
3. If TWR is low, cross-check Thrusters for S-tier picks.
4. Add Altimeter and velocity instruments before testing in co-op.
5. Log planet-specific gravity from Planets map when leaving Earth.

Tools do not replace flying — Approximately Up still surprises you with cable snags and RCS knob typos — but they cut repeat crashes on the same fixable mistake.

Tool vs in-game instruments

In-game velocity meters and altimeters read live state. Wiki tools use your inputs for planning. Treat discrepancies as a sign you mis-counted mass, forgot a fuel tank, or left a thruster in atmosphere-only mode on a vacuum leg.

Bookmark this hub before marathon building sessions. Run the thrust calculator every time you add frames, windows, or mission cargo — approximately up is easier when the numbers say you can lift off.
