Not necessarily...

If the SID is coded for runway track, then arming LNAV is the proper procedure (744).

Know your system, know your Jepps, and know your procedures!

Good point using TOGA, the track issue does not seem well defined in my company and intervention is not necessarily the most efficient method of obtaining runway track.

Intruder,

I did mean If cleared for take off and you're told "maintain runway heading" which I should have clarified.

I don't see how this can possibly be correct. If it really says that, I think your company manual is wrong.

Heading is heading and track is track; they are quite separate. Except when there is no crosswind component, they will always be different.

... an afterthought ...
 

SMOC, maybe you (and others) are confusing this with "Climb Straight Ahead", which is defined (UK) in both CAP413 and CAP493 as having the following meaning ...

Nope not confused, just towing the company line, for example often departing Taipei / Manila / Jakarta we are cleared "runway hdg" we depart in TOGA to maintain runway track however all flying in the US the same instruction we use HDG SEL. "Climb straight ahead" we would use TOGA for track again.

That phrase is not in the US Pilot/Controller Glossary, so the UK CAPs are "new information" for US pilots.

From FAA Order 8260.46C, Departure Procedure Program, page 10, par. 10.g(4):

TOGA: correct; it maintains rwy C.L. after lift off in B757/767. However, B737's depart in HDG SEL. Other types are a mystery to me.

Mod's could perhaps combine this thread with the other associated thread which is running in //.

Should be track
 

It should be track, all clearences from terrain/ obstructions after take off assume that you are following the extended centreline (or trying to!!). Look up the diagrammatic description for TODA and TORA in your regs.

Climb Straight Ahead
 

same case as stated in the most JEP'S approach chart in missed approach it say "climb straight ahead then......"

if you are in ND and MAP mode, setting the HDG bug to runway heading (the number) or set HDG bug to your Heading Pointer ?????:confused:

A "climb straight ahead then ..." clearance is to initially maintain runway extended centreline (i.e. a track). Therefore, the general Boeing answer to this is to use TO/GA, because this will provide the AP/FD with steering commands to maintain ground track. When airborne, you can align the HDG SEL to the achieved heading as you wish.
