What's the difference? (Normal and Steep Approach)

There is another important item regarding steep approaches: The aircraft to be used have to be certified for steep approaches and sometimes the software has to be customized.

Take the Embraer E190.
Its Control law system usually does not allow the speed brakes to be extended after going beyond Flaps 2.
However, in order to be able to maintain the approach speed (V REF) while descending faster, it is neccessary, to use the speed brakes even with Flaps FULL.

So they changed the software and also installed a special switch, labeled steep approach, which is activated on these approaches.

By the way, the E195 is not allowed to fly steep approaches.
