Bypasses, speed/flap configuration

[Driver170 42]

Part of my Preflight (RIBETS) check, for the S part it mentions - Enter max 220kts when no speed is specified in the FMC for 

initial turns on SID to assure track keeping. At the bottom.

 

Now lets say you had a DP for a speed max 190 knots and your flap bug speeds were, 1 was 190 and UP was 200 would you hold flaps 1 for the initial turn and what if you reach AA would you retract and would it still be safe to hold 190 flaps up?

 

 

SID briefing

The PF will first brief the intended departure routing. Briefings should 

always highlight the relevant MSA

 

• RTE page 1 and 2 - Confirm selected runway, SID and Transition 

where appropriate.

• INIT/REF - Confirm transition altitude

• LEGS - Identify each individual waypoint by reference to the 

departure (SID) plate. Include Tracks and Distances between these 

waypoints. Confirm speed/altitude restrictions and fly-over or fly-by 

waypoints. Ensure bypasses are minimized by selecting an 

appropriate speed/flap configuration to comply with the SID routing.

Enter max 220kts when no speed is specified in the FMC for 

initial turns on SID to assure track keeping

If the SID specifies 190 knots max then it's probably best to stay with Flap 1. The bug speed isn't the minimum so Flaps up would be probably be ok if you weren't manoeuvring.

So it would safe to retract even if your speed bug is between the 1 and up indicator?

Probably, but best to do that only when you are accelerating.

I mentioned above what if i reach my AA ?

AA is airline specific. SID is airport specific. Just stay at F1 until you pass the fix with the restrictions.
