Definition
One of three standard methods for entering a holding pattern, used when the aircraft approaches the holding fix from a heading roughly opposite the inbound holding course on the holding side. The pilot flies to the holding fix, turns to a heading parallel to the inbound course (in the same direction as the inbound leg), flies outbound for the appropriate timing or distance, then turns toward the holding side through more than 180 degrees to intercept the inbound course back to the fix.
Plain English
When you arrive at the holding fix from a direction that lines up roughly opposite to the holding course, you fly straight ahead alongside the holding course for one leg, then make a wide turn back across to rejoin the holding pattern.
Context Anchor
Seen in instrument flying when choosing the correct standard entry for a published or assigned holding pattern.
Derivation
‘Parallel’ comes from the Greek parallelos, meaning ‘alongside one another.’ The name describes the entry exactly: the aircraft flies a path running alongside the holding course before turning back to join it.
Why Pilots Care
Choosing the correct entry keeps the aircraft within the protected airspace of the holding pattern. Using a parallel entry when the geometry calls for a direct or teardrop entry can put the aircraft outside that protected area, creating obstacle and traffic risks.
Grounding Statement
Picture crossing the fix, briefly flying alongside the hold, then turning back to join the inbound path to the fix.
Intuition Check
Parallel does not mean you stay beside the hold indefinitely. In this procedure, the parallel part is only the setup before turning back to join the hold.
Example Sentence 1
Approaching the fix from the northwest with a southbound holding course and right turns, the pilot identified a parallel entry as the correct procedure.
Example Sentence 2
Approaching the fix from the non-holding side called for the parallel entry procedure to remain within protected airspace.
