What is a 'hot section inspection' requirement, and how might it affect ATC operations?
Answer: A turbine engine maintenance requirement that may ground aircraft unexpectedly, affecting filed ETAs
A hot section inspection is a scheduled turbine engine overhaul; if triggered unexpectedly (e.g., after a hard landing), it may cause an unplanned aircraft-on-ground situation affecting ATC traffic flow.
When a pilot reports 'heavy aircraft, speed unstable on approach,' what should the controller anticipate?
Answer: A possible go-around, requiring immediate sequencing adjustment for following traffic
An unstable approach is a leading indicator of a go-around; controllers must be prepared to adjust the sequence and provide a prompt go-around clearance if needed.
What is 'hydraulic failure' significance for an aircraft on approach?
Answer: May result in abnormal gear extension, reduced braking, and potentially longer landing roll requiring runway length or emergency equipment notification
Hydraulic failures can affect landing gear, flaps, brakes, and nose wheel steering, resulting in abnormal approaches, longer rollouts, and potential need for emergency equipment.
What is the purpose of 'speed control' issued by ATC to arriving aircraft?
Answer: To create and maintain proper spacing in the arrival sequence and reduce the need for radar vectors
Speed control assignments manage the spacing between arriving aircraft, helping controllers build consistent gaps for sequencing without excessive vectoring.
When an aircraft crew declares a pressurization failure, what altitude action do they typically take, and how should ATC respond?
Answer: Initiate emergency descent to 10,000 ft or lower; ATC should immediately clear the airspace below and provide direct routing
A pressurization failure requires an immediate emergency descent to approximately 10,000 ft MSL for crew and passenger safety; ATC must clear below and provide the most direct route to an airport.
What does a pilot mean when they report 'gear disagree' on approach, and what should the controller consider?
Answer: The landing gear indication shows a discrepancy — possibly one gear not locked — potentially requiring emergency equipment and extended approach time
A gear disagree indication means one or more gear may not be properly extended and locked, potentially requiring a low pass for visual inspection, extended troubleshooting time, and emergency equipment standby.
