Reference excerpt

The N.V. Vliegtuigbouw 013 Sagitta (English: Arrow) is a Dutch mid-wing, single-seat Standard Class glider designed by Piet Alsema and produced by N.V. Vliegtuigbouw. The aircraft is reported by different sources under a variety of different names and designations. Sources label it the Alsema Sagitta, Vliegtuigbouw Sagitta, N.V. Vliegtuigbouw 013 Sagitta, Dutch Sagitta, N.V. Vliegtuigbouw Sagitta 013 and N.V. Vliegtuigbouw Sagitta-013. The US type certificate erroneously lists it as the N.V. VLIEGTUIGBOUW Segitta (sic) 013 and catalogs it in their database under Vilegtuigbouw (sic), N.V., 013.

Design and development The Sagitta was designed by Alsema between 1957-61 specifically for the then-new FAI Standard Class. Like other early standard class gliders it was quickly surpassed in performance by newer fibreglass aircraft. The Sagitta has a wooden structure. The fuselage is covered with plywood, the wings and tail surfaces with plywood and doped aircraft fabric covering. The 15.0 m (49.2 ft) span wing features top and bottom air brakes and employs NACA 63-618 airfoil at the wing root, and a NACA 4412 section at the wing tip. The controls are automatically connected on assembly. The bubble canopy slides aft for cockpit access and can be locked open in several positions in flight. The landing gear is a fixed monowheel. In the Netherlands the aircraft was certified for cloud flying and aerobatics, but its US certification does not include these authorizations. The type received its US type certificate on 2 August 1965. Twenty Sagittas were built.

Operational history In July 2011 six Sagittas were still registered with the US Federal Aviation Administration.

Variants Sagitta Prototype first flown on 4 July 1960. Sagitta 2 FAI Standard Class model with 15.0 m (49.2 ft) wingspan. Super Sagitta FAI Open Class model with 17.0 m (55.8 ft) wingspan

Worked examples

Example 1 — a first encounter with N.V. Vliegtuigbouw 013 Sagitta

Start with the simplest possible case. Write down what N.V. Vliegtuigbouw 013 Sagitta 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 N.V. Vliegtuigbouw 013 Sagitta 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 N.V. Vliegtuigbouw 013 Sagitta 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 N.V. Vliegtuigbouw 013 Sagitta

In research: N.V. Vliegtuigbouw 013 Sagitta 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 N.V. Vliegtuigbouw 013 Sagitta 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: N.V. Vliegtuigbouw 013 Sagitta is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1960s Dutch sailplanes, Aircraft first flown in 1960, Glider aircraft, so understanding it makes those chapters shorter.
In everyday life: Look for N.V. Vliegtuigbouw 013 Sagitta 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.
