DC EMER CONF on airbus A 320 family

[Fly4passion]

Hy,


Does anybody know, why the DC EMER CONF has an higher landing distance factor than any other abnormal in the QRH ? and in particular if compared with an emergency electrical configuration?

I know that out there , there are a lot of you that can help me out ...thanks

At a guess I'd say because you lose more landing distance critical systems with DC config. I'd have a look at the ECAM Abnormals manual and see what systems are lost on both configs.

In elec emer config you have AC ess bus and DC ESS bus powered.
In DC emer config DC ESS bus is not powered when you select your gears so you dont have spoiler1+3+4+5. both reversers inop, normal brake, alt brake, auto brake, antiskid inop....have I missed any:eek: ? land config 3 so you approach with a higher speed.:\
