WHEN TAKING OFF AT Macedonian Airlines (Greece)">IN THE 737-800, AND USING TWO-PHASE ROTATION, DOES THE PILOT ROTATE TO 5 OR 6
DEGREES INITIALLY, THEN TO 10 DEGREES AFTER REACHING FULLY AIRBORNE?
Depends upon what technique is used/taught by the individual operator(s).
IS IT OK IF A PILOT ROTATES TO 5 DEGREES INITIALLY???
"Ok"? Sure, why not if not prohibited by your airline's operating manual.
AT WHAT PITCH ATTITUDE WOULD THE 737 800 HAVE A TAILSKID STRIKE?
I AM INCLUDING A PICTURE OF A 737 800 ON TAKEOFF ROTATION.....CAN U PLEASE LET ME KNOW APPROXIMATELY HOW MUCH DEGREES IT IS PITCHED (AS MAY BE SEEN ON THE ADI OF THE PFD)....
Any comment looking at a picture would be a "SWAG" [Stupid Wild-A** Guess].
FYI, some excerpts from my OpMan:
For optimal takeoff and initial climb performance, initiate a smooth continuous rotation at VR
at a rate of no more than 2 to 3 degrees per second to an initial target pitch attitude of 10 degrees. Normal liftoff attitude is between 8 and 9 degrees providing 20 inches of tail clearance at flaps 1 and 5. Tail contact will occur at 11 degrees of pitch if still on or near the ground. After liftoff, continue to raise the nose smoothly at a rate of no more than 2 to 3 degrees per second toward 15 degrees of pitch attitude.
Takeoff and initial climb performance depend on rotating at the correct airspeed and proper rate to the rotation target attitude. Early or rapid rotation may cause aft fuselage contact with the runway. Late, slow, or under-rotation increases takeoff ground roll. Any improper rotation decreases initial climb flight path.
With wheels on the runway and landing gear struts extended, aft fuselage contact will occur at 11 degrees pitch attitude.
On the HUD, if pitch exceeds the TO
/GA line, the chance of a tailstrike is significantly increased. The TO
/GA line remains at +10 degrees until 10 feet RA
, and then rates up at 2 degrees per second to match the PFD FD
Takeoff Flap--Liftoff Attitude--Tailskid Clearance
1 -- 8.2 -- 20"
5 -- 8.2 -- 20"
15 --7.8 --23"
25 --7.6 --25"
