Definition
A general term used in the Instrument Flying Handbook to describe modern integrated avionics — primarily Electronic Flight Displays (EFDs), Flight Management Systems (FMS), GPS-based navigation, autopilots, and related digital cockpit equipment — that have replaced or supplemented traditional analog instruments in current-generation aircraft.
Plain English
The modern, computerized cockpit equipment found in today's aircraft — digital screens, GPS, flight computers, and autopilots — instead of the older round mechanical gauges.
Context Anchor
Seen in instrument flying when a pilot uses screen-based flight displays, automated navigation equipment, or an autopilot during planning, flying, and monitoring a flight.
Derivation
Advanced comes from the idea of moving forward. Technology comes from older words connected with skill or practical craft. System means parts that work together. Together, the phrase points to aircraft tools that are more capable because several electronic parts work together, not just one separate device.
Why Pilots Care
These systems increase situational awareness and reduce workload but demand specific training to prevent misuse or over-reliance during instrument flight.
Intuition Check
Advanced Technology Systems does not mean the airplane is automatically easy or safe to fly. It means the aircraft has electronic tools that can help the pilot, but the pilot still has to understand and manage them.
Example Sentence 1
Before transitioning into the new aircraft, the pilot completed training on its advanced technology systems, including the primary flight display and integrated autopilot.
Example Sentence 2
Proper training on Advanced Technology Systems allows pilots to interpret navigation data quickly without scanning multiple gauges.
