Runway Remaining Monitor the separation with runway end
Runway Remaining Distances after which it is not possible to stop before the end of the runway at the given speed and deceleration 100 kts 80 kts 60 kts 0. 4 g Number of landings vs speed and remaining distance for 1 day in VHHH Hong. Kong VHHH
Runway Remaining One aircraft was at 60 kts with 1000 feet remaining 100 kts 80 kts 60 kts 0. 4 g Number of landings vs speed and remaining distance for 1 day in KATL Atlanta KATL
Reduced separation with runway end 1300 feet 2000 feet Exit Speed 20 kts Atlanta KATL

Monitoring Usage Operations Nb. of Crossings Nb. of Landings Ops Mix Nb. of Take-Off One day at Hong Kong RWY 07 R/25 L per nb of Operations per 15 min Runway Availability X Crossings per Day
Monitoring Separation Seconds between Take-offs and Landings Seconds between Crossings and Landings / Takeoffs One day at Hong Kong RWY 07 R/25 L per nb of Operations per 15 min X Crossings per Day
Future Work 1. Define Indicators relevant for monitoring of runway collision risk 2. Connect to ADSB data on ground level and hazard data 3. Automate the real-time generation of those indicators 4.
