Why are aircraft flights sometimes identified as heavy?
Aircraft have a maximum weight they can lift for a given altitude, so if they are on the limit of their weight allowance, they will be described as 'heavy'.
However this is not to be confused with a heavy lift capacity, which is a large aircraft that can haul large and heavy items, such aircraft are generally used by the military for transporting and rapidly deploying such items as Tanks.
Airplanes are often referred to as "aircraft" although this term is vague in that it applies to all flying vehicles. Thesaurus.com (linked below) gives these synonyms: aeroplane, airbus, aircraft, airliner, airship, cab, crate, jet, kite, plane, ramjet, ship I have also frequently heard pilots refer to their airplanes as "birds" They also sometimes are referred to as "iron" such that a pilot who is flying a heavy aircraft is flying "heavy iron" aircraft
Why is an aircraft called heavy Asiana 214 heavy emergency vehicles are responding we have everyone on their way?
Well simply because they are "ultra(very) light (low weight)" Let me clarify. There are heavy aircraft, like big transport planes. There are medium heavy aircraft like passenger jets. There are light (not heavy) aircraft like little private planes. Then there are Ultra Light aircarft which are vey light weight. So ultra meaning very and light meaning the opposite to heavy ... which maybe this answer is! LOL
When aircraft generate lift to fly, they leave an area of disturbed air behind them known as wake turbulence which can badly affect the control of following aircraft. This is especially dangerous during takeoff and landing, where the loss of control close to the ground can easily cause a crash. The heavier the aircraft, the stronger the wake turbulence. For this reason, the interval is increased in most instances for aircraft following or landing behind…
Heavy, clean, and slow VORTEX STRENGTH The strength of the vortex is governed by the weight, speed, and shape of the wing of the generating aircraft. The vortex characteristics of any given aircraft can also be changed by the extension of flaps or other wing configuration devices as well as by a change in speed. The greatest vortex strength occurs when the generating aircraft is heavy, clean, and slow.
Well there's no specific answer for this. there might be an average but it depends a lot on how heavy the aircraft is when it lands, how often it flies (and how long the flights are, shorter flights=more landings and take offs). And this is also a common misconception: the stereotypical large aircraft (aka airliner) landing includes a few screeches and a poof of smoke right when the tires touch down. however, contrary to popular…
When communicating with commercial planes why do air traffic controllers add heavy to the description?
All aircraft create disturbances in the air, known as wake vortex, when they fly. If a following aircraft flies in this disturbed area it can cause potentially dangerous control problems. The amount of disturbance depends on a number of factors, including aircraft speed, configuration (if the wheels are up or down, whether the flaps are deployed etc) and weight. Controllers need to take account of the wake vortex when separating aircraft, and since the amount…
Aircraft are equipped with instruments that measure the G-forces. That doesn't mean it detects gravity. Instead, these measure the forces on the aircraft, where 1 G Down is the normal weight of the aircraft. This information is recorded and stored on the aircraft and Flight Data Recorder so mechanics can determine if the aircraft experienced a hard landing or other heavy load.
The Boeing 737 is categorized as a Large Aircraft. The next category up is called a Heavy Aircraft and that category starts at 300,000 pounds (maximum certificated gross takeoff weight). A special "Heavy" category starting around 255,000 pounds was created for the Boeing 757 due to it's propensity to generate wake turbulence.
Aeronautical engineer is the one who designs aircraft. In the olden days before the inception of aeronautical engineer profession, aircraft designs were prepared by civil engineers. This is the main reason why old aircraft design employed many trusses in the structures because of such they were heavy. One modern design principle is the so called weight-to-strength ratio which contemplates the balance of the aircraft weight and structural strength. Thus, a good aircraft must be lightweight…
