this is not really a issue, so that is why it is not in #support
hey guys!
I was doing perth to london
and i rotated a little more hard than i wanted to, but not as much for a 5 second tail strike right?
that is right, after landing i looked at the replay and i had a 5 second tail stike, that kind of made the flight blah to me
but i rotated almost 3x hard on 777s A320s and so on, and some a MTOW at low speeds
anyway to takeoff with out a tailstrike on the 787?
Rotate at around 160 knots at a maximum 12 degreeâs of pitch. Iâve also had the same issue and thatâs how I do it. Try it on solo first though.
ok thanks, will give it a try next time!
Donât be aggressive on the rotate, just let the plane slowly rotate off!
Try to rotate slowly, and not at a low speed
What plane were you using? What was your rotation speed?
I will check out your page for the V speeds!
i was in a 787, ro ta tay was at 155 knots
I meant the variant đ remember, if youâre using the 787-10 youâll have more possibilities of a tail strike than if youâre using the 787-8
What was your weight? Were you overloaded?
oh, since i was doing perth to london, i was in a 787-9
I was in the weight that simbrife told me
around 94%
Next time remember to rotate slowly, as we donât have gear tilt thereâs more possibility of a tail strike
Also- the 787 family is really sensitive compared to other aircraft, so when you say that you rotate â3x harderâ on other aircraft, that might be why you had a tail strike with the 787 and not those other aircraft.
If Iâm that heavy I add some extra positive trim (50%) and add another flap setting. Once you reach 150~155 knots, the nose should come off the ground rather easy and then main gear will follow suit. Too aggressive with your input in the rotation and the tail will strike for sure.
Add some trim
Use more trim if your plane is heavy and start rotating at about 160-165kts if your plane is heavy. However since I donât know how much heavy was your plane, this speed is just an estimation
Everybodyâs given great advice âŚall I can say is the 787 is the only aircraft I fly here and well with correct flaps and speed for your weight try a 4 To 5 second count to 10 degrees is a good tool to ensure zero tail strikes. hope this helps. Happy flying!
Use +30/40% trim on takeoff and rotate very gently
Hey! Yeah a lot of people tend to have these issues with the 787, as everyone as said, the key is to use some trim and rotate gently, that way your takeoff will be perfectly smooth.
For a flight to Perth Iâll guess youâre fully loaded so you should be rotating between 160kts and above, not less than that, I do long hauls with the 787 too and always end up calculating around those speeds, it always works well.
You can also customize your sensitivity so this wonât happen as easily.
Lots of people here making general comments and suggestions, so Iâll give some actual examples:
Considering ârotate slowlyâ doesnât really mean much at all (slowly is subjective, of course) I can suggest the figure of 2°-2.5° per second of rotation. Be patient with it too, try not to force the nose to unstick.
Usually you would aim to pitch to around 12.5° positive pitch. However, this is not strictly speaking true - on takeoff, we actually pitch to hold a predetermined speed for a given thrust setting.
In other words⌠You were pretty heavy right. Vr probably wouldâve been around 165kts or so and your power setting pretty high, in the region of 95-96% N1. I guess V2 wouldâve been about 175kts. We normally aim to climb at V2 + 10-20kts. So for your particular case, after rotating (again, 2-2.5° per second) you would pitch to maintain a speed of about 185-190kts. This is know as V4 (you donât need to know that bit!) And is what you should climb at until you reach your acceleration height, usually 800ft AGL or 3000ft AGL depending on what noise abatement procedure is used for your particular SID.
Hopefully this clears everything up for you!
