WebTrak shows aircraft that are flying below 15,000 feet. As a result the display will first show aircraft when they descend below this altitude, this can happen anywhere on the display and so some aircraft can suddenly appear, this is quite normal. Where aircraft are climbing, WebTrak will no longer display its track once they climb above 15,000 feet.
