Takeoff wingtip strike in the Max threat is not addressed. [Company] ops specs call for rotation on takeoff towards 10 degrees of pitch. Operations Manual states in a note 'In some instances (gusty crosswinds; windshear) it may be necessary to hesitate at 10 degrees until liftoff occurs'. As the pitch increases; the wingtip clearance decreases since the 737 is a highly swept wing aircraft and the wing tips are aft of the center of rotation for pitch. In other words as the nose rises while the plane is on the runway; the wingtips go down. There are crosswind landing wingtip strike concerns when landing the [B737] Max with the cross control technique. This wingtip strike is of concern at a body angle of approximately 5 degrees at max crosswind (33 knots) during a cross control landing.In [the operating manual concerning] Takeoff in Gusty Wind or Strong Crosswind Conditions it states regarding liftoff; under sub paragraph Rotation and Takeoff; 'The aircraft is in a side slip WITH CROSSED CONTROLS at this point. A slow; smooth recovery from this side slip is accomplished after liftoff by slowly neutralizing the control wheel and rudder pedals'. Translation and concern is this - by the [operating manual] definition of crosswind takeoff techniques; the aircraft will be; during a strong crosswind takeoff; up to an approximately 5 degree higher pitch attitude (10 degrees; mentioned above) than during landing with the aircraft in a fully cross controlled state until well after liftoff. This guarantees; by the [operating manual] and sim pilot [B737] Max landing instruction training; a severe wingtip runway strike!At max crosswind there will be insufficient wing tip clearance during a textbook crosswind takeoff in gusty wind conditions. No mention is made of any [B737] Max takeoff guidance in any documents I can find; even though by current takeoff technique guidance and wing tip strike charts; an incident is guaranteed by my observation; at crosswinds well below max demonstrated crosswind limits. If I am correct; this must be addressed prior to line flying the [B737] Max. I cannot in good conscience fly the [B737] Max with crosswinds until this threat is addressed.
B737-MAX Captain reported an unresolved threat of a wingtip strike during crosswind landing and takeoff operations.
