Variometer A variometer – also known as a rate of climb and descent indicator (RCDI), rate-of-climb indicator, vertical speed indicator (VSI), or vertical velocity indicator (VVI) – is one of the flight instruments in an aircraft used to inform the pilot of the rate of descent or climb.

- One velocity will be positive, and the velocity in the other direction will be negative. The vertical axis of a velocity-time graph is the velocity of the object and the horizontal axis is the time taken from the start. Features of the graphs. When an object is moving with a constant velocity, the line on the graph is horizontal. When an object is moving with a steadily increasing velocity, or a steadily decreasing velocity, the line on the graph is straight, but sloped. The diagram shows some typical lines on a velocity-time graph. Speed - time graph The steeper the line, the more rapidly the velocity of the object is changing.

Vertical integration In microeconomics and management, vertical integration is an arrangement in which the supply chain of a company is owned by that company. Usually each member of the supply chain produces a different product or service, and the products combine to satisfy a common need. It is contrasted with horizontal integration, wherein a company produces several items which are related to one another. Vertical integration has also described management styles that bring large portions of the supply chain not o

Speed Conversion Speed Conversion. Speed is defined as the rate of change in position, expressed as distance traveled per unit of time. It is a scalar quantity with dimensions distance/time. Velocity is a vector quantity, the rate at which an object changes it's position. The speed calculation formula is: Speed = Distance / Time. Speed unit in SI system is meters per second (mps). Other common units are miles per hour (mph) and kilometers per hour (kph).

- The ADX indicator is in a unique class of indicators where the direction of the slope doesn’t necessarily mean strength in a particular direction. Instead a rising slope in the ADX means the strength of a trend is building in some direction.

- The vertical profile of a highway is made up of straight lines (grade lines) and curves, as shown in the following figure. The curves joining the grade lines are called vertical curves, and their function is to make a smooth transition from one grade to another.

MTC OGMS/DINF C) Any change of airspeed greater than 20 knots which is sustained for more than 20 seconds or vertical speed changes in excess of 100 ft/min. B) Any rapid change in wind direction or velocity which causes airspeed changes greater than 15 knots or vertical speed changes greater than 500 ft/min. C) Any change of airspeed greater than 20 knots which is sustained for more than 20 seconds or vertical speed changes in excess of 100 ft/min.

Velocity triangle In turbomachinery, a velocity triangle or a velocity diagram is a triangle representing the various components of velocities of the working fluid in a turbomachine. Velocity triangles may be drawn for both the inlet and outlet sections of any turbomachine. The vector nature of velocity is utilized in the triangles, and the most basic form of a velocity triangle consists of the tangential velocity, the absolute velocity and the relative velocity of the fluid making up three sides of the triangle.

What is Vertical Analysis? What is Vertical Analysis? Vertical Analysis is a process of economic report analysis in which all entries for each of the three main groups of account section (viz. liabilities, assets, and equities) in an estimated balance sheet is symbolized as the ratio of the whole account.

Describing Projectiles With Numbers: (Horizontal and Vertical Velocity) The numerical information in both the diagram and the table above illustrate identical points - a projectile has a vertical acceleration of 9.8 m/s/s, downward and no horizontal acceleration. This is to say that the vertical velocity changes by 9.8 m/s each second and the horizontal velocity never changes. This is indeed consistent with the fact that there is a vertical force acting upon a projectile but no horizontal force.

Travel Graphs â Distance & Time Velocity-time graphs/ speed-time graphs : A velocity-time graph has the velocity or speed of an object on the vertical axis and time on the horizontal axis. The distance travelled can be calculated by finding the area under a velocity-time graph.

Indicated airspeed Indicated airspeed (IAS) is the airspeed read directly from the airspeed indicator (ASI) on an aircraft, driven by the pitot-static system . It uses the difference between total pressure and static pressure, provided by that system, to either mechanically or electronically measure dynamic pressure.

Miles per hour Left-hand traffic, miles. Automobile speedometer, indicating speed in miles per hour (MPH) on the outer scale and kilometres per hour on the inner scale. In Canada it is the outer scale that is indicated in km/h and the inner scale in MPH, if the latter appears at all.

- Arrows along fault indicate relative or apparent direction of lateral movement. Arrow on fault indicates direction of dip. Low angle fault (barbs on upper plate). Fault surface generally dips less than 45° but locally may have been subsequently steepened. On offshore faults, barbs simply indicate a reverse fault regardless of steepness of dip.

Trans-Tasman Travel Arrangement A New Zealand permanent resident visa stamp granted on arrival under Trans-Tasman Travel Arrangement on an Australian travel document. The Trans-Tasman Travel Arrangement is an arrangement between Australia and New Zealand which allows for the free movement of citizens of one of these countries to the other. The arrangement came into effect in 1973, and allows citizens of each country to live and work in the other country, with some restrictions.

Rate of climb Speed and rate of climb [edit]. There are a number of designated airspeeds relating to optimum rates of ascent, the two most important of these are V x and V y. V x is the indicated airspeed for best angle of climb. V y is the indicated airspeed for best rate of climb. V x is slower than V y.

Rate of climb In most ICAO member countries (even in otherwise metric countries), this is usually expressed in feet per minute (ft/min). Elsewhere, it is commonly expressed in metre per second (m/s). The rate of climb in an aircraft is indicated with a vertical speed indicator (VSI) or instantaneous vertical speed indicator (IVSI).

vertical integration vertical integration. Merger of companies at different stages of production and/or distribution in the same industry. When a company acquires its input supplier it is called backward integration. When it acquires companies in its distribution chain it is called forward integration.

- An upward vertical velocity of just 6 centimeters per second can produce a large volume of precipitation if the moisture is present to be condensed. Let's apply upward vertical velocity to interpreting the synoptic scale forecast models (NAM,GFS etc.). Upward vertical velocity is plotted on the 700-mb prog. Go ahead and look at a 700 mb forecast panel on your computer. This prog is available on UNISYS weather at: You will see a panel full of colors, wind vectors, and height contours. The colors are the upward and downward vertical velocities.

- Just before it reaches the highest point, the vertical component of velocity is upward. Just after it passes the highest point, the vertical component of velocity is downwar…d. There's no way you can change from an upward velocity to a downward velocity smoothly without velocity being zero at some instant.

Initial Velocity Components An acceleration value indicates the amount of velocity change in a given interval of time. To say that a projectile has a vertical acceleration of -9.8 m/s/s is to say that the vertical velocity changes by 9.8 m/s (in the-or downward direction) each second.
