CLIMB GRADIENT
The climb gradient tables show the climb gradients for several weights,
temperatures and altitudes. These tables are published in the following
configurations:
GRADIENTS FOR TAKEOFF THRUST AND FLAPS 9
The gradients were obtained for a speed equal to V
2
+ 10 KIAS and
V
2
/V
S
ratio equal to 1.2. The thrust rating was T/O-1 with Anti-Ice OFF.
Corrections in the climb gradient for Anti-Ice ON and Flaps 22 are also
provided below each table.
GRADIENTS FOR TAKEOFF THRUST AND FLAPS UP
The gradients were obtained for a speed equal to 200 KIAS. The thrust
rating was T/O-1 with Anti-Ice OFF. Below each table are provided
corrections in the climb gradients for Anti-Ice ON and corrections for
climb speed equal to V
FS
.
GRADIENTS FOR CLIMB THRUST AND FLAPS UP
The gradients were obtained for the following climb schedule:
− 240 KIAS up to 10000 ft, increasing linearly to 300 KIAS at
12000 ft, maintaining this speed up to 20000 ft.
− The thrust rating was CLB with Anti-Ice OFF. Corrections in the
climb gradient for Anti-Ice ON are provided after the tables.
