secondary radar
A radar system that requires complementary aircraft equipment
(transponder)
The transponder generates a coded reply signal in response to transmissions from the ground station
(interrogator)
Since this system relies on transponder-generated signals rather than signals reflected from the aircraft, as in primary surveillance radar, it offers significant operational advantages such as increased range and positive identification.

sectional chart
An aeronautical chart
(using a scale of 1:500 000)
designed for visual navigation of slow- or medium- speed aircraft. Topographic information on these charts features the portrayal of relief and a judicious selection of visual checkpoints for VFR flight. Aeronautical information includes visual and radio aids to navigation, airports, controlled airspace, restricted areas, obstacles, and related data.

severe turbulence
Turbulence that causes large, abrupt changes in altitude or attitude. It usually causes large variations in indicated airspeed
(IAS)
Aircraft may be momentarily out of control.
severe weather forecast alert
