How to behave if the specified altitude is already in use.
public boolean isStrictAltitude(); public void setStrictAltitude(boolean strictAltitude);
This property specifies how the class's system driver should behave if the specified Altitude is already in use when the StartFilter method is called.
If this property is enabled, the filter will fail to attach. If this property is disabled (default), the driver will attempt to use an adjacent altitude value to attach the filter.
