Gets or sets the aircraft's airspeed in knots.

Gets or sets a value indicating that the aircraft's airspeed is higher than the maximum value that ADS-B messages can carry.

Gets or sets a value indicating whether the Airspeed property indicates true airspeed or indicated airspeed.

Gets or sets a value indicating that the Intent Change flag in a velocity message was set.

Gets or sets the difference between geometric and barometric altitude. Positive values indicate geometric altitude is above barometric, negative values indicate geometric altitude is below barometric.

Gets or sets a value indicating that the difference between the geometric and barometric altitude sources exceeds the maximum value that ADS-B can convey.

Gets or sets the aircraft's heading (not its ground track).

Gets or sets the margin for error for the horizontal velocity values.

Gets or sets the velocity and bearing when expressed in an ADS-B message as a pair of speeds along the X/Y axes.

Gets or sets the type of velocity encoded within the message, specifically whether it is airspeed or ground speed.

Gets or sets the vertical rate in feet per minute. Positive values indicate that the vehicle is ascending, negative values indicate the vehicle is descending.

Gets or sets a value indicating that the vertical rate exceeds the highest value that the ADS-B message can convey.

Gets or sets a value indicating that the source for the vertical rate is barometric as opposed to geometric.
