Jean Dabry 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 Jean Dabry rather than just read about it. In short: Jean Dabry (8 December 1901, Avignon – 5 July 1990, Montmorency) was a French aviator of the Aéropostale, then an airline pilot for Air France. He is buried in the Montmorency cemetery.

Key takeaways

Jean Dabry belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Jean Dabry to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Jean Dabry from memory before moving on to harder problems.

Reference excerpt

Jean Dabry (8 December 1901, Avignon – 5 July 1990, Montmorency) was a French aviator of the Aéropostale, then an airline pilot for Air France. He is buried in the Montmorency cemetery.

Biography Dabry gained his first officer-rank when he joined the Aéropostale in 1928 as navigator. Two years later on 12 April 1930 with Jean Mermoz as pilot and Léopold Gimié as radio-operator they made a closed circuit length record by floatplane. The aircraft, a Latécoère 28 fitted with a 600 hp Hispano-Suiza engine flew 4 345 km for 30h25. On 12 and 13 May 1930 the same crew performed the first crossing of the South Atlantic Ocean with the floatplane Laté 28 "Compte de la Vault" fitted with an Hispano-Suiza engine (600 hp). They flew between Saint Louis, Sénégal to Natal (Brazil). They delivered 130 kg of mail during this 3200 km journey. During the flight two records would be established namely, distance in a straight line for a seaplane and mail delivery time as they flew for 20 hours and 15 minutes. He became a captain at Air France in 1936. During his career he made more than 540 crossings of the North Atlantic Ocean. He became one of the executive directors of the company. He had logged 16,000 hours of flight time when he left Air France in 1957.

Worked examples

Example 1 — a first encounter with Jean Dabry

Start with the simplest possible case. Write down what Jean Dabry 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 Jean Dabry 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 Jean Dabry 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 Jean Dabry

In research: Jean Dabry 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 Jean Dabry 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: Jean Dabry is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1901 births, 1990 deaths, French aviation pioneers, so understanding it makes those chapters shorter.
In everyday life: Look for Jean Dabry 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.
