Definition of Time and Speed Table
A Time and Speed Table is a feature found on instrument approach procedure charts used in aviation. It serves as a guide for pilots by providing information on the distance between the Final Approach Fix (FAF) and the Missed Approach Point (MAP) and the estimated time of transit based on different groundspeeds.
The purpose of the Time and Speed Table is to assist pilots in making critical decisions during instrument approaches, especially when visibility is limited or when landing is possible only through instruments. The table helps pilots to calculate the amount of time they need to fly a specific distance, and this information is critical for making timely turns, adjusting altitude and airspeed, and achieving proper track alignment.
The table is depicted in a graph form, with groundspeeds on the horizontal axis and time on the vertical axis. The chart clearly shows the time required to travel a certain distance at a specific groundspeed, taking into account the expected wind speed and direction.
In summary, the Time and Speed Table is a valuable tool for pilots that can help them plan their approach more efficiently, reduce the chances of overshooting or undershooting their intended destination, and ultimately ensure a safe landing.
