On the Subject of Sky Plate

“Hours”? “Minutes”? What’s that?

The Plate on the module contains your Timer (in seconds).
It also contains two letters, being your starting city and target city respectively.

Using Appendix WORLD, you will fly around the World by plane.
Cities are the named nodes, flights are the links between nodes. Each flight has an associated duration, which might vary depending on bomb information.

In Appendix WORLD, Void all cities whose letter appears in the Serial Number.

Start at your starting city and move around the WORLD. For every flight, subtract the flight’s duration from your Timer. Before the next flight, you must Wait for the Next Plane to Arrive.

To fly to a city, input the city’s letter as Morse on the Plate.
The buttons represent a dot or a dash, while the last submits the current letter.

Submitting an invalid Morse, a city you cannot fly to from your current city, or having your Timer reach 0 outside of your target city will issue a Strike, and reset you to your starting city with your starting Timer.

Landing on your target city with the Timer below 600 seconds will Solve the module, as it reaches 0 after Waiting for the Next Plane to Arrive. Note that this is always possible within 2 to 4 flights.

You can fly to your target city before your Timer reaches 0. This won't solve the module nor strike.

In case it is needed, press the “SKY” text on the module casing to reset to your starting city with your starting Timer.

Waiting for the Next Plane to Arrive:

Imagine you’re at a bus stop, but this is a plane stop. Every plane departs every 600 seconds on the dot. No matter at which time you arrive in a city, the next flight is only possible when your Timer is a multiple of 600.

About Void:

Voided Cities are considered as if they do not exist.
If your flight brings you to a Voided City, keep going using the same line parity (full or dotted) until you land on a non-Voided City.
Count all flight durations you take, but you do not need to Wait for the Next Plane to Arrive until you land on a non-Voided City.
