CPC Aircraft Performance & Systems Knowledge for Controllers 3

Question 1

What is a 'hot section inspection' requirement, and how might it affect ATC operations?

Accepted Answer

A turbine engine maintenance requirement that may ground aircraft unexpectedly, affecting filed ETAs

Answer

A runway inspection required after hot brake incidents

Answer

A ramp check by FAA inspectors during peak traffic

Answer

An ATC audit of position records

Question 2

When a pilot reports 'heavy aircraft, speed unstable on approach,' what should the controller anticipate?

Accepted Answer

A possible go-around, requiring immediate sequencing adjustment for following traffic

Answer

The aircraft will increase speed and shorten the approach

Answer

The aircraft will declare an emergency and divert

Answer

No action needed — it is normal for heavy aircraft to vary speed

Question 3

What is 'hydraulic failure' significance for an aircraft on approach?

Accepted Answer

May result in abnormal gear extension, reduced braking, and potentially longer landing roll requiring runway length or emergency equipment notification

Answer

Only affects fuel consumption

Answer

Causes autopilot disconnect only

Answer

Has no impact on approach speed or landing distance

Question 4

What is the purpose of 'speed control' issued by ATC to arriving aircraft?

Accepted Answer

To create and maintain proper spacing in the arrival sequence and reduce the need for radar vectors

Answer

To make aircraft fly at maximum speed for efficiency

Answer

To prevent aircraft from exceeding airspace speed limits

Answer

To slow aircraft for weather avoidance

Question 5

When an aircraft crew declares a pressurization failure, what altitude action do they typically take, and how should ATC respond?

Accepted Answer

Initiate emergency descent to 10,000 ft or lower; ATC should immediately clear the airspace below and provide direct routing

Answer

Climb to FL450 for better air quality; ATC should provide immediate climb clearance

Answer

Hold altitude and divert to nearest airport without descending; ATC should provide divert clearance

Answer

Reduce speed only; ATC should issue speed reduction

Question 6

What does a pilot mean when they report 'gear disagree' on approach, and what should the controller consider?

Accepted Answer

The landing gear indication shows a discrepancy — possibly one gear not locked — potentially requiring emergency equipment and extended approach time

Answer

The aircraft weight exceeds landing limits

Answer

The crew disagrees on whether to land

Answer

The aircraft needs a runway change due to crosswind
