Fly runway heading question

Hello,

A quick question for the controllers out there. Lets say you have two parallel runways, 9R and 9L. You are on 9R and there is a crosswind from the Right. You are given cleared for takeoff, fly runway heading. On rotation, you have to crab 15 degrees to the right to stay over centerline.

Now obviously you don't want to drift into the departures off of 9L so you have to do the crab. But is this actually what is supposed to be done or should you actually fly the runway heading? I am sure that you fly the crosswind correction angle but would like to get an official answer as I have had this argument with a co-worker of mine. Thanks.

Fly the runway heading. This is what ATC is expecting.
 
Plus think about it...the guy taking off on 9L will be drifting to the left too so you will stay equally separated...unless he crabs 15 right which is no longer runway heading and then you will have an issue. Runway heading is runway heading...not track.

This. Fly the heading. Please.

I got barked at in SNA once for flying runway heading on departure, with winds out of the north-northwest at 40 knots. "Beercan 123AB, aren't you on runway heading?" "Yes, it's windy."

It's their (the controller's) problem for not noticing/correcting/compensating for the wind. You were doing the right thing :)

They disagreed somewhat at the time. Whether or not a loss of separation occurred I don't know.

"Runway track" is quite another matter.
 
From the PCG

Fly runway heading

The magnetic direction that corresponds with the runway centerline extended, not the painted runway number. When cleared to "fly or maintain runway heading," pilots are expected to fly or maintain the heading that corresponds with the extended centerline of the departure runway. Drift correction shall not be applied; e.g., Runway 4, actual magnetic heading of the runway centerline 044, fly 044.
 
71 means you worked too hard.

I have a feeling Bobduck is looking at this post right now thinking, "I just want to smack that kid sometimes."

Same thing happened to me recently. Was assigned runway heading (345) on departure from PSM, few minutes later:

ATC: N123AB, say heading?
Me: 345
ATC: I'm showing you tracking 310
Me: Roger, I'm getting the same on my GPS
ATC: were you briefed on winds aloft?

Well at that time I thought I was doing something wrong.

"Beg pardon sir, it's windy up here...would you like 10 right?"
 
Rotate, crab, heading select at 400', turn as necessary to fly the runway heading if you're crabbed.
 
Fly the backcourse if it's available. Seems like too much work on takeoff though.
The FMS I had in the ERJ-135/145 would fly a specified ground track even if "PROC HDG" was displayed on the NAV page. Technically, I feel like this was wrong from a "how the procedure is set up" stand point.
