• Small changes in RTA constraint [+3, −2] minutes from nominal induce large ERAM trajectory prediction errors, specifically for arrival metrics at 4 minutes before TOD: before TOD: — Up to 26 nm along track error at TOD — Up to 20% metering time error • Approx 4 min error at 20 min Lookahead — Up to 1100 feet altitude error at meter fix • Recommendations-Future Studies — Impact of sharing RTA clearance and FMS generated speed profiles with ERAM trajectory predictor • Trajectory prediction performance • Conflict probe (i.e., missed and false alerts) — May provide further insight into benefits
