Make every resource answer a plan

Pilots rewards a safe fuel margin, balanced inputs, and deliberate storage. Build for the next bottleneck instead of buying every lit card.

Fuel safety comes first

Every crew member consumes fuel. When fuel reaches zero with a negative net rate, recruitment stops and crew begin to desert. Unstaffed systems still run when they have inputs, but losing crew quickly cuts your staffed production and can ground aircraft.

Recovery order Ground fuel-burning routes if needed, move idle or lower-priority crew into Refueler work, then add fuel production. Do not add housing until the net rate is safely positive again.

Use the resource rail as a diagnosis

Amount

What you can spend now. A large stock is useful only when it supports the next unlock.

Cap

How much you can hold. Research and storage buildings often solve a blocked purchase more efficiently than another producer.

Net rate

Production minus upkeep and conversion. This is the clearest signal for whether your plan is sustainable.

ETA

Shown for nearby costs when the current net rate can reach them. A missing ETA is a prompt to change production.

Converters need a complete chain

Mines produce ore and coal; Smelters consume both to make iron. Later chains work the same way. A converter automatically throttles when an input is short, so inspect every required input before buying another copy.

  1. Check that the converter is enabled.
  2. Check each input’s net rate, not only its stored amount.
  3. Add the producer that is emptying first.
  4. Add storage only if the chain is healthy but caps too early.

Craft for a named purchase

The Workshop turns basic materials into advanced goods when you press a craft action. Crafting is not passive until later automation is unlocked. Use ×10, ×100, or Max only after checking which input the batch will consume.

Plan around weather without babysitting it

Seasons and live weather can change production and route risk. The Bridge shows current conditions and a short outlook. Keep ordinary operations safe without perfect weather; reserve riskier or expensive flights for favorable windows.

iOS: the resource rail scrolls horizontally as more resources unlock. Swipe it without leaving the current screen.
macOS: the resource rail sits below the window header. Use the optional Airfield pane for a second view of field status while another screen remains open.
