Not being familiar with the MD-10/11, how far can you have the flaps out before it starts to scream at you about the gear? In the ERJ, we can have up to Flaps 22 out (Flaps 45 is the final setting) with the gear up. However, the GPWS starts bugging us at 1200' RA...and in typical Embraer fashion, it's not subtle either.
