Aircraft Navigation Terms and Definitions

Aircraft Navigation Terms and DefinitionsAircraft Navigation Terms and DefinitionsAircraft navigation terms can often be confusing, especially when a pilot doesnt use them every day. Experience with cross-country flights and practical use of navigation techniques make these terms easier to identify. In the meantime, heres a review of navigation terms and the corresponding definitions. Speeds Calibrated Airspeed (CAS) - Indicated airspeed corrected for instrument or position inaccuracies. The calibrated airspeed can be found in the pilot operating handbook or on the airspeed indicator.Indicated Airspeed (IAS) - The airspeed read directly from the airspeed indicator.Groundspeed (GS) - The actual speed of the airplane passing over the ground. Groundspeed is true airspeed corrected for wind. You can find the aircraft ground speed by calculating it with a flight computer.True Airspeed (TAS) - The actual speed relative to the surrounding air. True airspeed is calibrated airspeed correc ted for nonstandard pressure and temperature. You can determine the aircrafts true airspeed with a flight computer. Altitudes Indicated Altitude - The altitude depicted on the altimeter. Remember that indicated altitude is the vertical distance above mean sea level (MSL), bedrngnis above the ground.Density Altitude - Pressure altitude corrected for nonstandard temperature. You can calculate density altitude with a flight computer.Pressure Altitude - The altitude shown on the altimeter when the altimeter is set to 29.92 inches or standard atmospheric pressure.Absolute Altitude - The vertical distance of the aircraft above the surface of the earth, or above ground level (AGL). True Altitude - The aircraft altitude above mean sea level (MSL). You can determine the true altitude with a flight computer. Directional True North - The geographic north pole is located at the northernmost point. True north is not the same location as magnetic north, due to the rotation of the earth i n relation to the earths magnetic field.Magnetic North - The northern location where the Earths magnetic force has the most downward pull. If you were to stand on magnetic north, a magnetic compass would point straight down. Magnetic north varies due to shifts in the Earths core and is at a different location than true north.Magnetic Variation - The angular difference between true north and magnetic north. Also known as declination. Magnetic Deviation - A magnetic anomaly that affects the compass. The magnetic compass in the aircraft is affected by surrounding magnetic and electrical disturbances in the airplane.Compass Heading - The aircrafts magnetic heading corrected for deviation. The deviation is found on a compass card or a placard near the compass, and it usually varies by just a degree or two.Magnetic Course - True course corrected for magnetic variation.Magnetic Heading - True heading corrected for magnetic variation. You can determine the magnetic variation from a sectiona l map. True Course - The aircrafts course over the ground relative to true north. True course is measured with a navigation plotter and a sectional map.True Heading - True course corrected for wind. Basic Calculations Time distance/groundspeed (td/GS)Distance groundspeed/time (dGS/t)Groundspeed distance/time (GSd/t)Fuel consumption Gallons/hour x time (GPH x T) Standard Atmospheric Conditions Standard Temperature 15 degrees Celsius or 59 degrees Fahrenheit.Standard Pressure 29.92 mercury or 14.5 psi or 1013.2 mb.

Student-Designed Heart Pump Is Lighter Than the Rest

Student-Designed Heart Pump Is Lighter Than the Rest Student-Designed Heart Pump Is Lighter Than the Rest Student-Designed Heart Pump Is Lighter Than the RestWhen his girlfriend needed heart surgery a few years ago, Dillon Hurd, then an engineering major at Iowa State University, did what engineers do best He began to design a machine that could serve as an artificial heart while patients wait for transplants or surgery.The SimVitae heart-assist device helps bridge the time between heart failure and surgery.These types of heart pumps, called left ventricle assist devices (LVADs), already exist, though only a few companies make them. Patients use themfrom the time of heart failure until surgery. People who are over 70 or in poor health, who dont qualify for a heart transplant, also use them. Many of the machines are large and cumbersome.Being an engineer, Hurd believed he could create a better solution. So he began designing an LVAD that would be lighter and more mobile.Hurds girlfrie nd is now his wife and, a few years after the surgery, is doing well. The LVAD he designed is now Hurds Ph.D. project at Iowa State. Hes also the founder of Hurd Health Group, which is gathering funding to bring his SymVitae wireless LVAD to market.For You Targeting krebs Drugs to 3D-Printed TumorsThe SymVitae differs from heart-assist products on the market because it uses a brushless electric motor as well as magnets placed on the inside and outside of the left ventricle. The magnets help guide the blood through the ventricles, while the electric motor pumps it through. Current devices rely on turbine engines to pump blood.Theyre like a small jet turbine in your chest connected to a car battery that you have to carry around all day. Their turbine design is inspired by NASA, so they really are small jet engines in every sense, he says. Theyre placed by coring into the heart, like youd remove a core with an apple. They stitch on a pump, then run a tube to the aorta and stitch it on there to bypass the left ventricle.The pumps, attached to the aorta, also come in contact with the blood supply, which can cause blood clots. If you throw a clot, its right in your aorta, he says. It can result in a life threatening situation or cause a stroke.The SymVitae skirts the patients aorta and doesnt touch the circulatory system.Hurds device calls for minimally invasive surgery to implant the magnets. An internal charging pad and battery pack powers the magnets, which create a natural force that pulls the blood through the heart.The patient wears an external charging pad and battery pack around his waist, which is hooked to the intern charging pack and battery. These batteries are wirelessly charged. Foreign materials dont touch the blood, which pulsates and moves with the hearts natural rhythm.Because the SymVitae is comprised of small components, surgery to implant them is less invasive than with other LVADs, he says.You can implant this without having to open up the ster num by breaking it.Dillon Hurd, Iowa State University and founder, Hurd Health GroupYou can implant this without having to open up the sternum by breaking it, Hurd says. Thats a hard surgery in itself, and if youre in heart failure youre not super healthy to begin with. Less invasive surgery means a better chance of success. The SymVitae will weigh around 300g (.66 lbs), while current LVADs typically weigh around 400g (.88 lbs) according to Hurds calculations. But the batteries and controller for those systems typically weigh about 18 lbs. Hurd says his entire system will be totally implanted and wont weigh more than 3 lbs., while his battery belt will weigh about 5 lbs.Hurd Health Groups next step is to apply for funding from the National Institute of Health and the National Science Foundation and a host of other agencies and organizations. The road ahead is to work further on the device, Hurd says.That means performing trials and tests, with the eventual goal of receiving FDA clea rance.Now, Hurd is enjoying time with his wife, the impetus for his fledgling business, and developing a device that might help people with heart failure live longer and easier lives.Jean Thilmany is an independent writer.Read MoreMini Sensor Detects and Measures What We EatThe Blood Test Goes MobileEngineers Contain Cancer Cells For Further Discussion
