HOLDING SPEEDS AND FUEL FLOW
Holding speeds vary with gross weight and altitude as given in the following chart. These speeds
provide the minimum practical fuel flow and corresponding performance (40% stall margin in 30°
bank, 50% in level flight) required to guard against speed instability and buffet.
BASED ON:
2 Engines Operating.
Flaps and Gear UP.
AC Pack ON.
Anti-Ice OFF.

* Add 5 knots to given holding speed (10 knots for grey box values) when holding
above 32,000 feet.
CORRECTIONS:
•
Increase/decrease fuel flow by 100 LBS/HR (0.1) for every 1
°C
above/below Standard
temperature.
•
Increase fuel flow by 5%, 200 – 300 LBS/HR (0.2 – 0.3), for Engine Anti-Ice ON.
•
Increase fuel flow by 20%, 800 – 1300 LBS/HR (0.8 – 1.3), for Engine and Wing Anti-Ice ON.
NOTE:
Notify ATC when holding at speeds faster than the following ATC holding speeds:
