Definition
An electronic unit that receives raw signals from one or more aircraft sensors and processes those signals into usable data for display systems, flight instruments, or other onboard equipment. The SRAP acts as the interface between the sensor itself and the systems that need to use the sensor's information.
Plain English
A box of electronics that takes the raw signal coming in from a sensor, cleans it up, and turns it into information the rest of the aircraft systems can actually use.
Context Anchor
Seen in aviation acronym lists, equipment references, maintenance notes, or NOTAM-related material for automated airport sensing systems.
Why Pilots Care
If a SRAP fails or degrades, the displays and instruments that depend on its sensor will show incorrect or missing information, even though the sensor itself may still be working. Knowing this helps pilots understand why a single failure can affect several indications at once.
Intuition Check
Do not read SRAP as a weather report itself. It is part of the equipment that receives and processes sensor signals before information can be reported.
Example Sentence 1
The SRAP failed during the flight, so the affected sensor data dropped off the multi-function display.
Example Sentence 2
During the preflight check the technician verified that the SRAP was receiving valid inputs from all connected sensors.
