Thank you for those replies!
I think have full landing config(F40 is the best) before abeam threshold is a good solution for 738's circling. Otherwise we will be too close to(or out of) the boundary, since we don't have Secondary Area while cirling under TERPS, that's extremely dangerous!
And i'm still waiting for answers for my qiz:
any jeppesen charts changed for this reason? or any plan to change? anybody has rumor for me?
thanks!
