Thanks for the comments guys lots of varying answers, a final question if some of you could answer when would you start configuring the flaps for landing i.e. commencing the final descent? I've been talking to a few local pilots at Cork and 15 nm to 20 nm seems to be the norm? I'm particularly interested in when you start to lower the flaps and do you need to lower them earlier if you're going to be landing with CONF 4 rather than CONF 3.
