WEIGHT LIMITS Takeoff Weight
The takeoff weight (weight at brake release or at start of takeoff roll) is limited by the most restrictive of the following:
.        
Maximum Climb Limited Takeoff - based on the aircraft's engine-out climb capability at a given density altitude  

.        
Maximum Runway Limited Takeoff Weight - determined by the ability of the aircraft to accelerate to takeoff speed on a given runway.  

.        
Maximum Certificated Takeoff Weight - the weight set by the manufacturer as the highest allowable under any conditions

.        
Obstacle Clearance, Enroute, and Landing Limitations

.        
Tire Speed and Brake Energy Limit Weights


Landing Weight
Maximum landing weight is limited by the most restrictive of the following requirements:
.        
Maximum Landing Weight (Runway Length plus Obstacle, and including Limitations for Inoperative Equipment)

.        
Maximum Landing Weight (Climb Limited)  

.        
Maximum Certified Landing Weight

ICE & RAIN PROTECTION Wing Anti-Ice Operation
.        
Wing anti-ice must be OFF for takeoff and must not be turned on prior to reaching 400 feet AFE. (AFM)  

.        
Do not operate wing anti-ice on the ground. (AFM)  


Operation In or Near Moderate To Heavy Rain, Hail, or Sleet
When flight in moderate or heavy rain, hail, or sleet is encountered or anticipated, engine start switches must be set to FLT and a minimum 45% N1 must be maintained except on short final when landing is assured.
FUEL Fuel Quantity
Maximum Fuel Quantity (at a density of 6.7 lbs/gallon):
Each wing tank:  10,000 lbs  
Center tank:  15,500 lbs  
737-300 Aux Tank (if installed):  2,800 lbs  
737-400 Aux Tank (if installed):  3,300 lbs  

Fuel Imbalance
Maximum allowable fuel imbalance between tanks 1 & 2 is 1000 lbs.
Fuel Usage
Use center fuel tank to depletion followed by main tank fuel; however, a maximum of 1,000 lbs may be retained in center tank provided the effects of balance have been considered.
FLIGHT CONTROLS Speedbrake Usage
Speedbrakes should not be deployed in flight at radio altitudes less than 1,000 feet AFE.
AUTO FLIGHT SYSTEM Autopilot
.        
Do not engage autopilot below 1200 feet AFE during takeoff. (AFM)

.        
Single Channel - The autopilot shall not remain engaged below 50 feet.  

.        
Dual Channel - The autopilot may be used for autoland.
