1. Types of Airspeed
- www.abbysenior.com
- Types of Airspeed.
- Variations in air pressure as altitude changes, errors in the pitot-static system, and other factors make determining airspeed more complicated than just reading a number on a dial. You should be familiar with several types of airspeed, each useful in different circumstances.
- Indicated airspeed (IAS) is the reading taken directly from airspeed indicator. ... Indicated airspeed drops as you climb, because as the density of the air decreases with altitude, fewer air molecules hit the pitot tube. ... For example, at cruise altitude, the airspeed indicator on the Boeing 737-400 may indicate about 280 knots when the airplane's actual speed through the air is more than 400 knots. Pilots use indicated airspeed to get the proper performance from their aircraft. ...
- Calibrated airspeed (CAS) is indicated airspeed corrected for installation error and instrument error. The difference between indicated airspeed and calibrated airspeed is usually greatest at low airspeeds, when the air flow around the static ports is turbulent. The position of the pitot tube and the installation of the airspeed indicator itself also contribute small errors to the airspeed indicator. ... To compensate for these errors, pilots refer to tables in the aircraft handbook to determine calibrated airspeed (CAS) under various conditions of flight.
- True airspeed (TAS) is the actual speed of an aircraft through the air. The airspeed indicator displays TAS only at sea level under standard conditions, so you must calculate TAS based on IAS, the current pressure altitude, and air temperature. ...
- Mach number is the ratio of the aircraft's true airspeed to the speed of sound. Aircraft that operate at high altitudes use Mach number, not airspeed, as a reference for aircraft performance and navigation, because the airspeed indicator is subject to many errors at high speeds in the thin air of the upper atmosphere. Mach number is calculated by a computer and displayed on the airspeed indicator.

- Airspeed .
- Airspeed refers to the speed of an aircraft in relation to the air which may be different from groundspeed which is the speed of the aircraft in relation to the ground. The difference between airspeed and groundspeed is a function of the velocity and direction of the wind. Airspeed is important because it determines the aerodynamic characteristics of the aircraft. ...

5. Airspeed Calibration

- Calibrating the Airspeed Indicator in your Coupe .
- How can you claim that your plane is better than the other guy's plane if your airspeed indicator may be way off? Also, it helps to know if you can get home before the sun goes down and how far you can go in a day. ...
- According to my Ercoupe 415-D owner's manual, the calibrated indicated airspeed and indicated airspeed should be identical at 100 mph. ...
- If my test shows that, after 45 years, the accuracy of the airspeed indicator is still that good, then I'll just go by my indicator from now on. If my calibrated indicated airspeed is faster than my indicated airspeed, then I want to check my pitot/static system for leaks. ...
- Knowing the correction factors for the airspeed indicator in my plane will mean that the other measurements will actually mean something. ...
- Here are some types of airspeed I'll discuss: .
- True airspeed: the speed the airplane is really flying through the air. ...
- Indicated airspeed: the speed shown by the airspeed gauge. ... Indicated airspeed would then match true air-speed (after indicated airspeed is corrected for any installation errors. ...
- When the true airspeed is exactly the same at high altitude as at low, the high altitude indicated airspeed is lower.
- Indicated airspeed is reduced by high temperatures, too. ... ) The amount by which indicated airspeed is lower than true airspeed is known pretty well. If you know the indi-cated airspeed, pressure altitude (altimeter set to 29. 92), and temperature, your E6B or flight calculator will tell you the true airspeed. ...
- Calibrated indicated airspeed: the speed you would calculate by applying a correction factor to the indicated airspeed. If the gauge, tubing, and pitot tube location were all perfect then the gauge would give you true indicated airspeed. Since there are often errors in installation or in the gauge there needs to be a correction factor at each airspeed. You take the raw indicated airspeed, add or subtract the correction factor and you get the calibrated indicated airspeed. ...

- The Mach Airspeed Indicator (MASI ) is an RVSM compliant unit. In Standby mode, it processes pitot-static pressure, total air temperature, and altitude input data to compute and display calibrated airspeed (CAS), true airspeed (TAS), Mach number, and not-to-exceed airspeed (Vmo) data. ...
- It performs airspeed hold monitor and overspeed alert functions, as well as data checking, fault detection and status indication functions. A multifunction PUSH SEL pushbutton selects operating mode and airspeed displays. The MASI also has a Command Bug Adjust Knob for setting target airspeeds, IMI Ring Markers used in setting airspeed reference points, and a TEST Button for activating the instrument self-test and fault history display functions.

- Airspeed Aims to Reduce Turnaround Time.
- This effort, “Airspeed,” was chartered in April by Rear Adm. ... Airspeed will deploy a standardized “tool box” of cycle-time reduction methodologies across the three NAVAIR depots.
- The overall goal for Airspeed: decrease production turnaround time.
- “Airspeed is intended to reduce turnaround times and costs by employing a set of modern business techniques. ...
- According to Widick, Airspeed will use proven cycle-time reduction techniques to improve depot productivity and efficiency, “thereby reducing the number of required depot pipeline assets, resulting in a cost avoidance to the Navy. ...
- Airspeed kicked off at North Island with the landing gear components shop. ...
- “Over the next 30 months, Airspeed will be deployed throughout the depot corporation. ...
- Massenburg’s vision for Airspeed is to incorporate the most current business and cycle-time reduction processes across the naval aviation enterprise to enable reduced cycle times. ...
- “Airspeed will enhance depot responsiveness and flexibility; increase the velocity of our maintenance, repair and overhaul processes; eliminate waste and inefficiencies; and identify constraints and barriers for focused management attention,” Trainer said.
- He said Airspeed would also share, export and integrate Airspeed cycle time reduction processes across the naval aviation enterprise through NAVRIIP.
- “Airspeed will leverage theory of constraints, lean, six sigma and internally developed management philosophies to dramatically improve depot maintenance cycle time, reduce depot pipeline, reduce waste and increase enterprise wide supply chain velocity,” said Trainer. ...

- Topeka The pilot's failure to maintain adequate airspeed, low altitude during takeoff and trees all contributed to a private plane crash that killed a commander in the Kansas Air National Guard.
- Mike O'Toole's failure to maintain adequate airspeed resulted in a stall at takeoff that likely caused the crash.
- "It was his failure to maintain the airspeed, which is possible during a stall. ...
- Don O'Toole, Mike O'Toole's father and former state aviation officer, said an airplane stalls when the angle of the wings is too high for the airspeed.
- The report doesn't say why the plane stalled or why O'Toole failed to maintain adequate airspeed.
