How we can calculate Altitude of an Aircraft?

Aircraft don’t really exactly know their altitude. They fly at a pressure, that is indicated as an altitude via equations in the Standard Atmosphere. What is the altitude of a plane in flight? When flying a plane, the pilot needs to know exactly how high above the earth the plane is traveling, a measurement that is called altitude. Types of Altitude: Indicated Altitude Let's start with the easiest - indicated altitude is simply the altitude you read directly off your altimeter. If uncorrected for pressure changes, your altimeter won't be very useful. True Altitude True altitude refers to the height of an aircraft above sea level. This type of altitude is measured in terms of “feet above mean sea level". Pressure Altitude Pressure altitude is a measurement of the aircraft’s altitude above a standard datum plane Pressure altitude is also used in many flight planning calculations, including determining takeoff and landing distances. Density Altitude Density altitude is pressu...

Gustave Eiffel -A Pioneer in Experimental Aerodynamics

The First Question comes in our mind,  The Man Who built Eiffel Tower,  How he has became a Pioneer in Experimental Aerodynamics?  So lets start to answer the question and some  Aerospace  Facts. Who Was Gustave Eiffel? Gustave Eiffel was a French engineer who designed and oversaw construction of the Eiffel Tower. Alexandre-Gustave Eiffel was born in Dijon, France on December 15, 1832.he attended the École Polytechnique (Polytechnic School) and later the École Centrale des Arts et Manufactures (College of Art and Manufacturing) in Paris, graduating in 1855. Short Information about Eiffel Tower:  Eiffel is most famous for what would become known as the Eiffel Tower. The work started in 1887 for the 1889 Universal Exposition in Paris. The tower is composed of 12,000 different components and 2,500,000 rivets, all designed and assembled to handle wind pressure. How he has became a Pioneer in Experimental Aerodynamics: The most used term Aerodynam...

Elmer A. Sperry_Father of modern navigation technology.

                           The First Question comes in our mind : 1 :Who was Elmer Ambrose Sperry?    2 :What was the Gyroscopic Compass?     Elmer Ambrose Sperry Sr. (October 12, 1860 – June 16, 1930) was an American inventor , and Father of modern navigation technology. In the year 1913, Sperry created a gyro that could control the elevators and ailerons of an aircraft through a series of servos. 2 :What was the Gyroscopic Compass:     A Gyroscope (from the Greek ‘gyro’ means turn or revolution and ‘skopein’, means to view) is an apparatus in which a heavy flywheel or top rotates at high speed, the turning movement resisting change of direction of axis.  There are 4 laws or facts act upon which gyrocompass operation depends, the first two are internal properties of the gyroscope namely. 1:Gyroscopic inertia (rigidly in space) 2:Precession  3: Earth   rotati...

Venus Is Hotter Than Mercury...

Venus, the second planet from the sun, is named for the Roman goddess of love and beauty.  The planet — the only planet named after a female — may have been named for the most beautiful deity of her pantheon because it shone the brightest of the five planets known to ancient astronomers. The average temperature of Mercury is about 442.5K whereas Venus has an average temperature of 735K. The reason for these temperatures being the presence of atmosphere in Venus and absence of atmosphere in Mercury. Venus has the thickest atmosphere in our Solar system. The atmosphere mainly consists of Carbon dioxide and some Nitrogen. The carbon dioxide rich atmosphere generates the strongest greenhouse effect in our Solar system, which means that heat will be trapped inside. Also, as the heat is trapped inside, the weather spreads the heat across the whole planet and therefore, the whole planet has a temperature of about 735K. It is a completely different story in Mercury. As it ha...

NASA's InSight Lander

               InSight - Studying the 'Inner Space' of Mars A United Launch Alliance Atlas 5 rocket, designated AV-078, will launch NASA’s InSight lander to Mars.  InSight will touch down in the Elysium Planitia region of Mars in November 2018 to study the Martian interior and search for ongoing seismic activity. The rocket will fly in the 401 vehicle configuration with a four-meter fairing, no solid rocket boosters and a single-engine Centaur upper stage.  The InSight mission seeks to uncover how a rocky body forms and evolves to become a planet by investigating the interior structure and composition of Mars. The mission will also determine the rate of Martian tectonic activity and meteorite impacts. The phases of the InSight mission include: Pre-Launch :   Preparing for the mission includes pre-project planning, science definition and instrument selection, landing site selection, assembly and testin...

Amelia Earhart _First Women Aviator & Pilot .

Amelia Earhart Her disappearance in 1937 during an attempt to fly around the world is a mystery that continues to intrigue people worldwide. Amelia Mary Earhart was born in Atchison, Kansas, on July 24, 1897. Amelia Mary Earhart    an American aviation pioneer and First Women Pilot.Earhart was the first female aviator to fly solo across the Atlantic Ocean. Earhart was 12 years old before she ever saw an airplane, and she did not take her first flight until 1920. Amelia Earhart was so thrilled by her first airplane ride that she quickly began to take flying lessons. Some major accomplishments of Amelia Earhart : - January 3, 1921 – Began flying lessons with Neta Snook. July 1921 – Bought first plane, the Kinner Airster (named “The Canary”) October 22, 1922 – Broke women's altitude record when she rose to 14,000 feet. June 17-18, 1928 – First woman to fly across the Atlantic; 20hrs 40min (Fokker F7, Friendship) Transatlantic flight in 1928 ...

TOP 8 Fastest Airplanes in the World.

Fastest Airplanes in the World. FIRST FLIGHT :   On December 17 th  1903, Orville Wright finally achieved something that mankind had dreamed of for the entirety of human history. He made the first sustained and controlled heavier than air powered flight, and even though that pioneering flight was only 120 feet long, Orville, and brother Edgar inspired a thousand others to build bigger, better, and above all faster flying machines in the century that followed their historic achievement. Find out what the top Eight fastest planes in the World today are Here. ## NUMBER 8 :  Mikoyan MiG-31 Foxhound The Mikoyan MiG-31 is a supersonic interceptor aircraft developed for use by the Soviet Air Forces. The model was developed from the earlier MiG25 Foxbat and shares design elements with its predecessor. Maximum speed : 3,000 km/h At high altitude: Mach 2.83 (3,000 km/h; 1,860 mph) At low altitude: Mach 1.21 (1,500 km/h; 932 mph) Cruise speed : Mac...
