Vertical separation for jets and turboprops operating at up to and including FL 290 is what?

Vertical separation minima are the safety distance required between two IFR aircraft along the vertical axis. For jets and turboprops operating at or below flight level 290, the standard en route vertical separation is 1000 feet. This means two aircraft on different flight levels must be at least 1000 feet apart in altitude, which aligns with how flight levels are defined under standard pressure (1013.25 hPa) and provides a reliable margin against minor altitude deviations or instrument error. The other options are not consistent with this established minimum: 2000 feet would be more than necessary for this band, 1500 feet isn’t the standard minimum, and 100 feet is far too small and unsafe.
