GoJet recommended holding speed above 15,000 feet up to and including Flight Level 310?

• A. Two Engines - 225 Knots
• B. One Engine - 220 Knots
• C. Three Engines - 235 Knots
• D. Four Engines - 230 Knots

Answer: (A)

Holding speeds are chosen to balance stable turning performance and enough stall margin in the hold, and they change based on engine configuration. In the altitude band from 15,000 feet up to and including flight level 310, the prescribed holding speed for a two‑engine configuration is 225 knots. This number reflects the aircraft’s performance with both engines producing thrust: it lets you execute standard‑rate turns in the hold without approaching stall or exceeding safe margins, while still being efficient and controllable in the high‑altitude environment.

If one engine is inoperative, the recommended speed drops slightly to 220 knots to maintain safe control authority and margin in an asymmetric thrust condition. The values for three or four engines (235 knots and 230 knots) show how much more thrust capacity would allow a faster hold in those hypothetical cases, which isn’t applicable to this two‑engine aircraft but is part of the broader performance data. Since this aircraft operates with two engines, 225 knots is the appropriate hold speed in this altitude range.
