Reference excerpt

The Wassmer WA-30 Bijave is a French two-seat advanced training glider designed and built by Wassmer Aviation of Issoire.

Design and development

The WA-30 Bijave is two-seat development of the Wassmer WA-21 Javelot II and the first Bijave flew on 17 December 1958 from Issoire Aerodrome. The Bijave is a cantilever shoulder-wing monoplane with a welded steel tube fuselage covered with fabric and reinforced plastic. The wing is made from wood, covered in birch forward of the spar and fabric to the rear, it has no flaps but is fitted with retractable perforated wooden airbrakes. The pilot and passenger sit in tandem in an enclosed cockpit with individual transparent canopies. The landing gear is a fixed monowheel, a wooden rubber-sprung skid under the nose and a steel tailskid.

Worked examples

Example 1 — a first encounter with Wassmer WA-30 Bijave

Start with the simplest possible case. Write down what Wassmer WA-30 Bijave 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 Wassmer WA-30 Bijave 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 Wassmer WA-30 Bijave 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 Wassmer WA-30 Bijave

In research: Wassmer WA-30 Bijave 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 Wassmer WA-30 Bijave 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: Wassmer WA-30 Bijave is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950s French sailplanes, Aircraft first flown in 1958, Glider aircraft, so understanding it makes those chapters shorter.
In everyday life: Look for Wassmer WA-30 Bijave 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.
