Aero Linx: The Australian Parachute Federation The Australian Parachute Federation exists to administer and represent Australian Sport Parachuting. This is achieved by promoting and maintaining a high level of safety and by improving the standard of Sport Parachuting to encourage participation and excellence in performance. The APF is the organisation which controls skydiving and parachuting at most civilian operations in Australia. With the approval of the Civil Aviation Safety Authority (CASA) it sets the standards of operation, conducts competitions, issues licences and instructor ratings, conducts exams and distributes various publications to keep its members informed of current events and safety standards.

Ground Stop Ground Stops are implemented for a number of reasons. The most common reasons are: To control air traffic volume to airports when the projected traffic demand is expected to exceed the airport's acceptance rate for a short period of time. To temporarily stop traffic allowing for the implementation of a longer-term solution, such as a Ground Delay Program. The affected airport's acceptance rate has been reduced to zero. How it works: Flights that are destined to the affected airport are held at their departure point for the duration of the Ground Stop.

"The discovery of Kepler-186f is a significant step toward finding worlds like our planet Earth. Future NASA missions, like the Transiting Exoplanet Survey Satellite and the James Webb Space Telescope, will discover the nearest rocky exoplanets and determine their composition and atmospheric conditions, continuing humankind's quest to find truly Earth-like worlds."
