Flight manuevering load acceleration flaps down?
+2.0g to 0.0g
Runway slope for takeoff and landing?
+2.0% to -2.0%
Max takeoff tailwind component?
Maximum landing tailwind component?
Maximum dry runway wind limits takeoff and landings.
Maximum steady state wind velocity?
Maximum gust velocity?
50 kts maximum steady state
20 kts maximum gust
NOTE: Takeoff crosswinds limits are based upon the most adverse aircraft loading and assume an engine out RTO.
Maximum dry runway wind limits takeoff and landings. Notes about gust velocities?
Gust velocities are advisory; however, operations with a steady-state near the limits with higher gusts should be considered unacceptable. The captain may choose to further reduce these limits based on such factors as mels, gust velocity, runway width/length, braking action, wx phenomena, pilot currency and time in type of aircraft.

What is the max crosswind component for a sideslip only landing?
Sideslip only landings are not recommended with crosswind components in excess of 17 kts at Flaps 15; 20 kts at Flaps 30; or 23 kts at Flaps 40. This ensures adequate ground clearance and is based on maintaining adequate control margin.
What is the minimum ground time after landing on the NG if max quick turnaround weight limit is exceeded?
If max quick turnaround weight limit is exceeded on landing, wait at least 67 minutes after aircraft block-in, then check wheel thermal plugs to ensure they have not melted.

Max takeoff and landing weights further limited
Takeoff and landing weights may be further limited by center of gravity, performance, and MEL/CDL considerations. These lower limits will be annotated on the Dispatch Release unless the limit is driven by actual aircraft loading. When limited by actually loading, the reduced limit weight will be indicated on the Load Closeout.
