October 24, 201312 yr Is it true that the entry point to a TCA is always the Initial Approach Fix (IAF)?

November 14, 201312 yr Is it true that the entry point to a TCA is always the Initial Approach Fix (IAF)? Not sure I understand. TCA is a north americanism (TMA or terminal manoeuvring area everywhere else in the world). Controlled airspace is built up like an upside down wedding cake with a CTZ (control zone) at the bottom, extending up generally around 1,500 agl, a CTA above the CTZ extending to around 3,000ft, then the TMA above that up to the base of class C airspace at FL195. Since you'll descend from class C into the TMA from above rather than entering laterally it isn't a fixed point; and this will be considerably higher than the IAF. Additionally, not every approach has an IAF anyway. Jordan Forrest
