CPC Separation Standards & Traffic Flow Management

Question 1

What is the standard vertical separation minimum between aircraft operating in Class A airspace below FL290?

Accepted Answer

1,000 feet

Answer

Standard vertical separation in Class A airspace below FL290 is 1,000 feet between aircraft.

Question 2

Which separation method uses distance-measuring equipment (DME) to maintain spacing between aircraft on the same route?

Accepted Answer

Longitudinal separation

Answer

Longitudinal separation maintains spacing along the same route or track, often using DME or time-based intervals.

Question 3

When two aircraft are converging at approximately the same altitude, the minimum radar separation standard in en route airspace is generally:

Accepted Answer

5 nautical miles

Answer

The standard en route radar separation minimum is 5 nautical miles between aircraft at the same altitude.

Question 4

Traffic Flow Management (TFM) programs such as Ground Delay Programs (GDPs) are primarily used to:

Accepted Answer

Absorb en route delays at the destination airport

Answer

GDPs delay aircraft on the ground at origin airports so they arrive at the destination airport at a manageable rate, absorbing anticipated arrival delays.

Question 5

The EDCT (Expect Departure Clearance Time) issued during a GDP represents:

Accepted Answer

The window in which the aircraft is expected to depart the origin airport

Answer

An EDCT is a time window assigned to a flight during a GDP specifying when the aircraft is expected to depart its origin airport.
