Gibraltar Aerobeacon

Gibraltar Aerobeacon 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 Gibraltar Aerobeacon rather than just read about it. In short: The Gibraltar Aerobeacon built in 1841 is one of several lighthouses in Gibraltar, the British Overseas Territory at the southern end of the Iberian Peninsula. It is also known as the Gibraltar Aviation Light and Gibraltar Aero Light.

Key takeaways

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

Reference excerpt

The Gibraltar Aerobeacon built in 1841 is one of several lighthouses in Gibraltar, the British Overseas Territory at the southern end of the Iberian Peninsula. It is also known as the Gibraltar Aviation Light and Gibraltar Aero Light. The active beacon is positioned atop the Rock of Gibraltar and is operated by the Government of Gibraltar.

History While The Lighthouse Directory suggests that the Gibraltar Aerobeacon does not strictly meet its criteria for a lighthouse, the publishers of the directory indicate that the light merits an exception. In Publication 113, it is referred to as the Gibraltar Aviation Light; in The Online List of Lights, it is referred to as the Gibraltar Aero Light. The light by all three names has the same Admiralty number (see infobox). The Gibraltar Aerobeacon (pictured in link below) is positioned on top of the Rock of Gibraltar. The Rock is approximately 22 miles (35 km) in length. About six furlongs (0.75 miles (1.21 km)) to the south of the north end of the Rock is the signal station at 1,255 feet (383 m). The 1911 Encyclopædia Britannica indicated that, at the station, "the names and messages of passing ships are cabled to all parts of the world." The map of Gibraltar reveals Signal Hill close to the end of the cable car line, at 387 metres (1,270 ft). The Gibraltar Aerobeacon is a square, skeletal tower which features a large gallery platform on which there is a round radar apparatus. The light characteristic is remarkable for a red light which flashes the Morse Code for Gibraltar. It consists of two long flashes and a short flash, after which there is a long flash and three short flashes. The code for Gibraltar is emitted every ten seconds. The range is 30 nautical miles (55 kilometres or 34.5 miles). The active beacon has a focal plane (or focal height) of 405 metres (1329 feet). The site and the light tower are closed to the public. The Gibraltar Aerobeacon is operated by the Government of Gibraltar. The United Kingdom Hydrographic Office Admiralty List of Lights and Fog Signals number is D 2456. The United States National Geospatial-Intelligence Agency (NGA), formerly the National Imagery and Mapping Agency (NIMA), number is 4256.

Worked examples

Example 1 — a first encounter with Gibraltar Aerobeacon

Start with the simplest possible case. Write down what Gibraltar Aerobeacon 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 Gibraltar Aerobeacon 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 Gibraltar Aerobeacon 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 Gibraltar Aerobeacon

In research: Gibraltar Aerobeacon 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 Gibraltar Aerobeacon 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: Gibraltar Aerobeacon is common in secondary-school and first-year university syllabi. It links to neighbouring topics Beacons, Lighthouses completed in 1841, Lighthouses in Gibraltar, so understanding it makes those chapters shorter.
In everyday life: Look for Gibraltar Aerobeacon 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.
