What is airspeed trend vector?
The Airspeed Trend Vector is a vertical, magenta line, extending up or down on the airspeed scale, shown to the right of the color-coded speed range strip. The end of the trend vector corresponds to the predicted airspeed in 6 seconds if the current rate of acceleration is maintained.
What information is given by the speed trend arrow on the PFD?
A vertical arrow, called the speed trend arrow, indicates the aircraft’s predicted speed in 10 seconds if the current acceleration or deceleration rate remains constant.
What speed equals the upper limit of the white arc on the ASI?
The white arc denotes the airspeeds at which it is safe to deploy the flaps. The maximum speed is called Vfe. The bottom end of the white arc is set at the stall speed Vs0 when the aircraft is configured at maximum take-off weight usually with one or two stages of flaps deployed.
What does a trend vector do?
For example, some systems generate “trend vectors” that predict the aircraft’s airspeed, altitude, and bank angle up to several seconds into the future. The primary flight instruments that appear on a PFD are driven by instrument sensor systems that are more sophisticated than conventional instrument systems.
What does the speed trend on a PFD mean?
The Indicated Airspeed is depicted by a yellow index line against a moving white scale on a gray background. A vertical arrow, called the speed trend arrow, indicates the aircraft™s predicted speed in 10 seconds if the current acceleration or deceleration rate remains constant.
What are the rules for a trend line?
Rule #1. Any trend line should connect at least 2 tops or 2 bottoms. Rule #2. A top is called a “Swing High” and consists of a minimum of 5 candles: 2 candle on each side of it which prices that don’t exceed the lowest point.
How are speed lines used in a downtrend?
Applying speed lines to a downtrend, the first line is drawn from the recent high price the downtrend began from to the most recent low of the downtrend. The 1/3 line would be drawn to represent a one-third upward retracement of the downtrend, and the 2/3 line to represent a two-thirds retracement of the downtrend.
Which is the first line in an uptrend?
Although you can simply apply a speed lines indicator to a chart, speed lines are also easy to draw yourself. The first line in an uptrend is drawn from the low price point, or start, of the uptrend to the most recent high price reached in the trend.
