CTO Air Traffic Control Procedures & Communications 4

Question 1

What squawk code should a controller assign to an aircraft experiencing a radio communication failure?

Accepted Answer

7600

Answer

Transponder code 7600 indicates a radio communication failure (NORDO), distinguishing it from hijacking (7500) and general emergency (7700).

Question 2

When issuing a taxi clearance to a runway crossing, which element is REQUIRED by FAA Order 7110.65?

Accepted Answer

An explicit clearance to cross each runway must be issued separately

Answer

Each runway crossing must be explicitly cleared by the controller; blanket taxi-to-runway clearances do not authorize runway crossings.

Question 3

An aircraft on final approach reports a bird strike and loss of engine power. The controller's FIRST action should be:

Accepted Answer

Notify the ARFF immediately and clear the runway

Answer

With an emergency aircraft on final, the controller must immediately notify ARFF and ensure the runway is clear to support the landing.

Question 4

What is the correct controller response when a pilot states 'Unable' to a clearance or instruction?

Accepted Answer

Acknowledge and issue an alternative clearance that meets the pilot's capability

Answer

When a pilot declares 'Unable,' the controller must acknowledge and work to find an alternative that is both safe and operationally acceptable.

Question 5

Under FAR Part 91, pilots of large turbine-powered aircraft must report which condition to ATC immediately upon detection?

Accepted Answer

A TCAS Resolution Advisory (RA)

Answer

FAR 91.221 requires pilots to notify ATC immediately whenever a TCAS RA is issued, as it may conflict with ATC instructions.
