Which of the following is a data item used to estimate the flight duration in the planned data?

Estimated time enroute is the forecasted duration from takeoff to landing under planned conditions. It’s the key value used to estimate how long the flight will take because it combines the planned route distance with expected cruise speed and winds, giving a single time figure to base the schedule and operations on. Cargo load affects weight and can influence fuel burn and performance, but it doesn’t provide a direct time estimate for the flight. Flight number is merely an identifier, and FMS Reserve Fuel is a fuel quantity reserved for contingencies, not a time estimate. So, the data item that directly estimates flight duration in the planned data is the estimated time enroute.
