Leaving / Rejoining SID - all types

[General_Kirby]

As many different answers for as many different types would be great thanks.

Scenario -

You depart on a SID programmed into the FMS. You rotate and engage the automatics and prepare to snooze...


You then get taken of the SID for whatever reason and get given a heading to fly, (maybe due unknown traffic, weather etc etc)

ATC then want you back on the SID asap. Is a heading from ATC pointing you in the right direction easier OR does the A3xx B7xx have a magic button than can take you from heading mode direct to rejoin the SID?
I know nothing about FMS'...


Finally again for A3xx and Boeing, is it easier to fly a heading, or a track? Or no difference?

ATC would most likely have you rejoin the SID via a waypoint. So you just push Direct and the waypoint and go back to NAV mode. Otherwise you could just arm NAV and fly an intercept heading until you are back on track.

As for heading vs track, I can't speak for all Boeing and Airbus products but for A310/320/330/340 you can fly a track between 2 points, or a heading, but you can't just dial in a track the way you do a heading.

General, in a 717 in the scenario you describe, by selecting NAV the aircraft will turn and intercept the SID track, the intercept angle varying depending upon how far one is displaced from the track.

My experience has been that ATC will clear one to a waypoint ahead, rather than require one to regain the SID ASAP. Mind you, my not so worldly experience is all in Australia.
