MD-11 and MD-90

Does anybody know the autopilot bank angle limitations for the MD-11 and MD-90 during departure below FL100?

Thanks in advance.

Bank Angle Limit - MD-11

From the FCOM:

The commanded bank angle limit will be the bank angle selected with the bank angle limit selector and the FMS computed bank angle limit.
If the bank limit is selected to AUTO, the limit value will be the least of a value varying linearly from 5° at 340 KIAS to 25° at 210 KIAS and the 1.3g buffet limit.
At 1.3 V stall, the limit is further constrained to a maximum roll angle of 15°.

If the bank angle limit selector is set to the AUTO position, the bank angle limit will vary as follows:

• Between 15° and 25° from zero Mach to Mach 0.17
• Limited to 25° between Mach 0.17 and Mach 0.55
• Reduced linearly to 20° at Mach 0.80, 10° at Mach 0.87, and wings level at Mach 0.93

So for departure below FL 100 the bank limit would vary between 15° and 25°, depending on speed.

And to complete the picture...

When the aircraft is stabilized on the localizer, the bank angle limit will reduce to 10°. At 200' the bank angle will be further reduced to 5°.

Hope this helps.
