737-800 landing pitch limit??
according to the chart in the manual, when the pitch reach more than 11 degrees, there will be a tail strike, my question is: this number is based on the landing gear struts are all the way compressed or neutral position? please shed me some light~thank you ~
|
You think it matters? :eek:
|
I am wondering if the landing gear is fully compressed, the 11degree pitch limit maybe reduced.
|
You must have a different chart to me! Mine says 11.5 degrees struts extended and 9 fully compressed. What is your document?
|
Boeing FCTM section Take Off and Initial Climb gives 11 degrees struts extended.
Section 6.21 " landing" shows pitch angle approx 9 degrees and associated tail clearance with struts compressed. Same chart also shows data with struts extended...quite how you land with the struts completely extended is beyond me! |
yeah, I think it is a different chart.
And I found that in my FCTM, during landing when the landing gear strut is extend, the tail strike attitude is 11 degrees, and for the landing gear strut compressed it says a little bit more than 9 degrees. and my 737-800s have the SFP qulification but one position tailskid. |
Same on mine. Both in the company manual and the Boeing docs... In any case, don't even come close to these limits - please :D I flinch during takeoff every time I don't hear the 'clack' and the pitch hits eight or more...
|
I think the landing gear strut fully extended during landing only happens when the crew need to make a go-around at 0 altitude without enough power.
and it may lead to a tail strike~ |
.....or one of my 'greasers':)

737 700-800-900 Tail Strike Attitude
I have been trying to read through thr FCTM and the COMs but i dont seem to find the Tail strike attitude mentioned. But looking at the above given replies, 11 seems to be a safe bet. But if anyone has an exact value, please pass on the information.
Thank You |
Its all in fctm.
In my airline,any pitch above 7degr should trigger an 'attitude' call out by pnf. Vref at pitch about 5 is target,not like im looking inside or anything:E |
On the FCTM look for "Touchdown body Attitudes" then "Body clearance at touchdown". Anything above 8 degrees is asking for it on the -800. If I read correctly 8 deg pitch = 8 inches of clearance struts compressed.
|
simple one I was taught on my conversion to 737-800 - dont exceed 10 degrees pitch up below 10 feet RA (on take off) easy to remember!
