Definition
An evasive maneuver during a simultaneous close parallel PRM approach in which the pilot climbs and turns away from an adjacent aircraft that has deviated into the No Transgression Zone. The maneuver is initiated immediately on ATC's breakout instruction and takes priority over the published missed approach.
Plain English
If another aircraft strays toward your approach path during a closely spaced parallel approach, the controller tells you to climb and turn away right now. You stop the approach, climb to the assigned altitude, and turn to the assigned heading without delay.
Context Anchor
Seen in Precision Runway Monitor approach material, where two aircraft may be flying instrument approaches to closely spaced parallel runways at the same time.
Derivation
Breakout' comes from the idea of breaking out of the approach sequence. 'Climbing' is added because most breakouts on PRM approaches require an immediate climb to gain vertical separation from the threatening aircraft, distinguishing it from a descending or level breakout.
Why Pilots Care
Provides immediate lateral and vertical separation from traffic on the adjacent runway.
Intuition Check
Do not read “breakout” as simply seeing the runway or breaking out of clouds. Here it means an urgent escape maneuver away from the approach path. “Climbing” does not just describe a normal climb; it is part of the assigned avoidance action.
Example Sentence 1
When the controller called 'Traffic Alert, climb and maintain four thousand, turn left heading two-seven-zero,' the crew flew the climbing breakout immediately and disconnected the autopilot.
Example Sentence 2
The pilot executed the climbing breakout and climbed to 3,000 feet while turning 45 degrees away from the parallel approach.
