DC-10-30 at 380,000 pounds out of MSP at FLEX temp 49 degrees Celsius and STP (I can't my 580,000 pound TOGA sheet):

V1- 130
Vr- 136
V2- 148
Vf (minimum speed to start retracting the flaps at)- 163
Vzf (minimum clean wing speed)- 231

Optimum climb speed: 293

T/O N1= 102.5%


For a 508,000 pound DC-10-40 (less powerful engines), at FLEX 00 temp and STP out of DTW:

V1- 162
Vr- 166
V2- 177
Vf- 196
Vzf- 267

Optimum climb speed: 320

T/O EP= 1.51

The -30 speeds are a bit less than these as it has much more powerful engines.

I forgot, this is with Slats in takeoff position and 19 degrees of flaps for the -30, and 22 (or maybe 24...) degrees of flaps for the -40. It's been a while since ive been in the plane and some of the little differences between the two aircraft are clouding themselves together.

I thought the DC-10 had

Flaps Up, 0 (slats), 5, 10, 15, 22, 35, and 50 degrees

And slats 15 at flaps zero, 35 at flaps 35, and 50 degrees at Flaps 50.

There's also a dial-a-flap, as a customizable flap-setting that enables you to select a flap setting from 1 - 21 degrees I think.

I know on the MD-80 there's a similar dial that enables a custom setting from either 18, or 23 flaps. The idea is that you can use 18 for a takeoff or 23 on long final for slowing down. Useful because going to 28 without the gear will elicit an irritating warning sound. 23 without the gear enables you to avoid the warning sound, and slow down a bit, drop the gear, and go to 28. At least that's what I think.

No, the DC-10 Flaps/Slats are as follows:

Flaps/Slats
up/retract
0/takeoff
15/takeoff
22/takeoff
35/land
50/land

Plus dial a flap with slats at takeoff.

The NW -30's have the notches at up, flaps 1(slats only), 19, 24, 35, and 50.

The -40's have the settings as you descibed.
