While Las Vegas controllers in many cases allow for VFR services through their Class B airspace, there are times when workload prevents them from doing so. To avoid the airspace, pilots flying in higher terrain south and east may have to delay their climb or descend earlier than what they have become accustomed to. Also, an area known as the “Henderson Practice Area” is now restricted at 7,000 feet – a drop from 8,000 feet. Other modifications to the Class B shelves provide more space for VFR pilots. For example, an area over Henderson Executive Airport provides more space for pattern operations at the airport.
