Aerocivil Colombia air traffic controller CTA foundations cheat sheet

Separate requested, cleared, read back and observed information.

Communication transfer and control transfer are different events.

Project the traffic situation using trends and explicit model assumptions.

Arithmetic meeting time is not a separation authorization.

Actual Colombian publications and unit procedures govern operational decisions.

Primary reflection differs from cooperative secondary replies.

ADS-B broadcasts and multilateration timing are different mechanisms.

A display label does not establish independent source integrity.

Pressure altitude, geometric height and slant range retain distinct references.

Alerts assist monitoring rather than replacing the controller's traffic picture.

Compare the actual readback with the instruction, not with expectation.

An emergency does not stop the rest of the traffic situation evolving.

A handover distinguishes completed actions, pending actions and uncertainty.

Request appropriate help while retaining clear roles and qualification boundaries.

Fatigue awareness and motivation alone do not guarantee unimpaired performance.

A small dew-point spread indicates proximity to saturation, not certainty of existing fog.

Compare environmental and parcel lapse rates using the supplied assumptions.

Hemisphere and system geometry matter to wind-shift claims.

Visible cloud or radar boundaries do not contain every hazard.

Decode day, time, units, trends and scope before drawing conclusions.

A radial, bearing, selected course and aircraft heading are different quantities.

TO/FROM is not simply a report of aircraft nose direction.

DME is slant range, including the vertical component.

A pressure altitude is not automatically exact geometric separation.

Published instrument procedures take precedence over a generic display shortcut.
