Kaishiki No.1

Kaishiki No.1 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kaishiki No.1 rather than just read about it. In short: The 会式一号機 (Kaishiki No.1, kaishikiichigouki) was the first successful Japanese-designed and constructed airplane. It was designed by Captain Yoshitoshi Tokugawa and was first flown by him on October 13, 1911, at Tokorozawa in Saitama Prefecture.

Key takeaways

Kaishiki No.1 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Kaishiki No.1 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kaishiki No.1 from memory before moving on to harder problems.

Reference excerpt

The 会式一号機 (Kaishiki No.1, kaishikiichigouki) was the first successful Japanese-designed and constructed airplane. It was designed by Captain Yoshitoshi Tokugawa and was first flown by him on October 13, 1911, at Tokorozawa in Saitama Prefecture. There is a replica displayed in the Tokorozawa Aviation Museum, located near the place where the aircraft's first flight took place.

Worked examples

Example 1 — a first encounter with Kaishiki No.1

Start with the simplest possible case. Write down what Kaishiki No.1 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kaishiki No.1 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kaishiki No.1 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kaishiki No.1

In research: Kaishiki No.1 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Kaishiki No.1 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Kaishiki No.1 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aircraft first flown in 1911, Biplanes, Pusher aircraft, so understanding it makes those chapters shorter.
In everyday life: Look for Kaishiki No.1 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
