Question: 1 / 400

Is it true or false that when using vertical separation the lead aircraft must always be the same speed or faster?

True

False

When using vertical separation in air traffic control, it is not necessary for the lead aircraft to always be the same speed or faster than the following aircraft. Vertical separation relies on the altitude differences between aircraft, not their speed. As long as the required vertical separation minimum is maintained, the trailing aircraft can safely operate at a slower speed than the lead aircraft without compromising safety. This principle allows for more flexible management of air traffic, particularly when considering varying flight profiles, such as climbs and descents.

The other options suggest conditions or restrictions that do not reflect the basic principles of vertical separation in air traffic control. Vertical separation applies broadly, regardless of the type of airspace or the category of flights involved.
