Embraer E-Jet speed brakes for steep glideslopes
Do any E-Jets that approved to operate in short fields with steep glideslopes like London City have the speed brake protection system override?
According to FCOM:
--
If extended during approach, the speed brakes will automatically retract upon selection of slap/flap 2 or above.
Speed brakes will not be deployed if airspeed is below 180 KIAS, and also automatically retract if airspeed decreases below this threshold.
--
Lufthansa City Line guys somehow make the approaches with the speed brakes partially deployed in Flap Full conf.

With the steep approach option there is a new mode for the Multi function spoilers that effectively gives a final approach similar to the old direct lift control on the L1011. In fact one might assume they copied that idea after abandoning their original ventral airbrake concept ;-)

The spoilers deploy, and are controlled automatically during a steep approach.
The spoiler lever stays in the closed position.
If it wasn't for the spoiler deployment, the a/c would probably do the approach at flight idle, with possible spool up problems on the go around.
Not that you'd ever have to go around somewhere like London City mind.....
