1.)After I rotate what speed am i targeting?

 

2.)I pretty much do all of my flying in the US which has a max speed of 250knots under 10,000feet. at what point should I select 250kts do be realistic? I've usually done it after I've retracted the flaps.

 

thanks! happy new year!

1. Rotate to 15 degrees nose up initially, then adjust pitch to maintain V2+20.

 

2. At acceleration height, default is 1500ft AGL.

 

 

I'd recommend looking through the NGX tutorial and start getting your head around VNAV which will take care of all this for you

1.)When I rotate what speed am i targeting?

 

That would depend on your aircraft weight, runway length etc.

Just some very broad and general tips from me:

1. You get your V1, VR and V2 speeds from the FMC take-off page. I assume you are doing a non-derated takeoff.
    
   
2. When rotating, your pitch is quite important (more so than aiming the speed). Aim for about 7 degrees nose up.
    
   
3. When confirming positive climb, raise the nose up smoothly to approx 15-18 degrees and gear up. You should have your flight director turned on, and VNAV and LNAV too (they wont engage b4 after 300 ft agl if I remember correctly). That way your crosshair will tell you where to aim. You want minimum v2 + 20 speed, but dont overspeed your flaps. The lighter you are, the higher you have to pitch your nose to keep from overspeeding (exchanging forward speed for vertical speed).
    
   
4. At accelleration heigh (approx. 1500 ft above ground level (AGL)) lower the nose to around 8-12 degrees nose up, and gradually raise your flaps to a clean configuration. Remember the speedlimit of 250 knots below FL100. Do your after takeoff checklist

Yeah thanks. I mean to put after I rotate. ahaha

is there a time it wouldn't be 1500ft?

Depends on the noise abatement departure procedure you are using. For example you may sit at V2+20 to 3000ft AGL before accelerating in built-up or noise-sensitive areas.

are the acceleration heights printed on the STAR charts somewhere?

You would find them with the charts for each airfield, however it may be in a "textual information" section, rather than printed on any SID.

ok, can you think of any examples? Will it just say "accel height: " or something to the like?

1.)After I rotate what speed am i targeting?

V2 + 20 is the initial climb speed recommended in the B737NG FCTM, although speeds between V2 + 15 and V2 + 25 are acceptable, and will result in similar initial climb profiles.

 

flying in the US which has a max speed of 250knots under 10,000feet

Remember the speedlimit of 250 knots below FL100.

I better clarify this before someone else such as scandinavian13 jumps on this. The commonly misunderstood speed "limit" of 250 KT at 10000 ft may be broken if the aircraft requires it, which most often occurs when the aircraft weight is high enough that the minimum flaps clean speeds exceed 250 KT. If you use VNAV (which is recommended), the aircraft should automatically set climb speed below 10000 ft to whatever speed is necessary for safety.

 

When rotating, your pitch is quite important (more so than aiming the speed). Aim for about 7 degrees nose up.

If you provide the specific variant you fly, I can give you some precise rotation figures from the FCTM.

 

is there a time it wouldn't be 1500ft?

If tight terrain clearance during initial climb is a possibility, acceleration height may be higher.

After I rotate what speed am i targeting?

 

In normal situations, initiate a smooth continuous rotation a VR toward 15 degrees pitch attitude. After liftoff, use the flight director as the primary pitch reference cross checking indicated airspeed and other pitch performance related flight instruments. Using this technique, liftoff should occur in 3 to 4 seconds and rotation speed is about 3 degrees/second.

A proper rotation will result in about a V2 + 20 airspeed. Continue to folloe and pitch to the command bars though.

 

I pretty much do all of my flying in the US which has a max speed of 250knots under 10,000feet. at what point should I select 250kts do be realistic? I've usually done it after I've retracted the flaps.

 

After the flap are retracted, dial in 250 kias in the IAS window or select VNAV unless you've been given an ATC climb speed restriction or the SID specifies a minimum speed segment.

 

 

is there a time it wouldn't be 1500ft?

 

Your company my specify another altitude for acceleration as low as 400 feet agl (CFR) to 1000 feet agl more common for 737 Ops). The captain, during an engine out emergency may use what ever acceleration height deemed necessary in the interest of safety.

 

 

are the acceleration heights printed on the STAR charts somewhere?

 

No, usually not on SIDs (US). Acceleration heights can be found in company SOP's.

The FMS has a default profile built in (you can modify it) so just follow the guide of the flight director to get an idea what to do. If in future you want to hand fly with no director you will understand default way or do it anyway you want.

In the US, it's usually by company SOP.

 

Some countries have the info on noise abatement pages or airport info pages.

My company uses 1000'. We have OBST alts in our T/O data as well that we maintain Vclean until passing.

...aaaaaaand that just made my morning. Thanks Owen!

You're welcome! I figured you would come across it sooner or later.

 

Well, I guess it just goes to show that you have successfully instilled some knowledge in the AVSIM community, or at least in this flight simulator enthusiast. . . .

 

Have a great year!
