Newbie--some basic questions about takeoff

Featured Replies

Happy new year!I'm a very amateur PIC 767 user. Although I can takeoff, land, and navigate, I still have some questions.1. Takeoff speedsNo matter what I use as my ZFW (usually 245,000) and my reserves, the V1 for flaps at 15 is always 157. Isn't this a bit fast? Shouldn't the V1 change in response to my fuel load? Something I'm missing here?2. Takeoff using keyboard commandsOnce I hit V1, I guess I'm supposed to "pull back" by using the number 2 on the number pad to increase pitch. The question is... When do I begin to pull back? (Before V1, exactly at V1?) And how much pitch do I need to take off?3. Activation of VNAV and LNAVWhen should these be activated? On the ground or after takeoff? I think that this is dependent on individual airline policy, but is there a standard technique?Thanks for your help.

If you fuel the aircraft differently before each flight and follow the full preflight procedures in the FMC, V1 will vary. If you have a different fuel load and V1 is staying the same, you are skipping important parts of the preflight routine.>2.

I depart with nothing activated. After passing 400 feet, I activate FLCH but do not turn on the autopilot until at least 1000 feet. Most of the time not until around 4000 feet. Activation of LNAV is departure specific for me. It all depends on vectored vs. RNAV departure. I activate VNAV at around 10,000.Hope this helps you some. It sounds like you need to do a little more homework in the PIC manual regarding your first 2 questions.

Almost all Airlines that fly the 757-767 use that setting although a "FEW" might use 15 as stated in thier SOP. V1 @ 157 does seem very odd indeed. You sure thats not Vr?>2.

(Before V1, >exactly at V1?) And how much pitch do I need to take off? At V1 start lifting the nose at roughly 2.5 degrees per sec and commence Vr at Ref speed. DO not rotate past 15* nose up on climb out. >3. Activation of VNAV and LNAV >When should these be activated? On the ground or after >takeoff?

This might be a Airline SOP thing in the real world but for FS you can arm both on the ground of course this does nothing without CMD engaged. At 400' AGL you are free to engage CMD. I arm LNAV myself on the ground and clean up the bird at 1000' AGL, hand fly till my transistion VOR and engauge CMD, VNAV. NOTE! I'm not sure if others engage VNAV on the ground along with LNAV, but I have had no problems doing so. Maybe someone else here can give us the correct procedure if there is one.Best Wishes,Randy J.

In regard to question 1, its very likely that you're aren't completing the FMC correctly and as Mike points out, you'll need to dig into the 767 PIC FMC manual for futher explanations.It also occurs to me that it would be very difficult, although not impossible, to fly 767 PIC with only a keyboard.

Hi newbie, I arm both VNAV and LNAV on the ground as I have seen done in airliner videos , just make sure that u have armed both the flight director and autuothrottle beforehand. I engage both around 2000'.

"At V1 start lifting the nose at roughly 2.5 degrees per sec and commence Vr at Ref speed. DO not rotate past 15* nose up on climb out."I thought we supposed to lifting the nose at Vr, and when hit V1, i should put my hand from throttle to my controller, did i miss something?

tomchou,You are correct. Hands off the power levers at V1 (committed to take-off), rotate at 2.5 deg per second at Vr.Kevin in CYOW.
