Definition
A holding pattern flown by aircraft operating at higher true airspeeds, typically turbojets and turboprops at higher altitudes, where ICAO standard holding speeds and larger protected airspace dimensions apply. Above 14,000 feet MSL, maximum holding speeds increase (up to 265 knots in some segments), and the holding pattern's protected airspace is larger to account for the wider turn radius and longer leg distances flown at high true airspeed.
Plain English
Holding done by faster aircraft at higher altitudes. Because the aircraft is moving faster through the air, the holding pattern itself is bigger, the allowed speeds are higher, and the airspace set aside to protect the pattern is wider.
Context Anchor
Seen in instrument holding discussions, especially for jets, turboprops, and other aircraft that may enter a holding pattern at higher speeds.
Derivation
High performance' in aviation refers to aircraft capable of higher speeds and altitudes than light piston aircraft. Combined with 'holding' (waiting in a defined airspace pattern), the term simply means holding patterns adapted for fast, high-altitude aircraft.
Why Pilots Care
Prevents high-speed aircraft from drifting outside protected airspace or creating conflicts with other traffic during holding.
Analogy
A faster car needs more room to make the same turn. A faster airplane also needs more room, so holding at high speed must be managed before the aircraft gets outside the intended area.
Grounding Statement
At the same bank angle, a faster airplane makes a wider turn and travels farther during each part of the holding pattern.
Intuition Check
High performance does not mean the holding pattern is better or more advanced. Here it means the aircraft’s speed and capability can make the holding pattern harder to contain within the protected area.
Example Sentence 1
Climbing through FL240 toward the holding fix, the crew briefed high performance holding speeds and the longer leg timing that came with them.
Example Sentence 2
Before entering the hold, the pilot adjusted the pattern size for high performance holding due to the aircraft's higher airspeed.
