Use the up and down arrows against any of the parameters to change their value or click on the value and enter a new value. See the associated parameters change accordingly.
Click on any of the units to cycle through the available units.
The Delta box shows the step change that the arrows will induce for the last parameter selected. To change the Delta value, click on it to select it, key in a new value and press Enter. Delta values are individually stored for each parameter.
The Delta Calc button calculates the change in pressure for a small change in Altitude or Airspeed, at the currently selected Altitude or Airspeed.
The MA>FT or MA>KN button changes which parameter (Altitude or Airspeed) is affected when changing the Mach.
