It seems like the autobrake is not working properly on my 737-600/700. I loaded the 600 with 39,000 pounds of cargo and passengers. Then I loaded 8000lb of fuel. I then took off a runway and climed to 1800 feet agl on runway heading. I then with the plane stable on autopilot did a procedure turn to intercept the ILS and slowed the airspeed to 180, flaps 5, established on the LOC. I then armed the spoilers and set the autobrakes to 2. As the GS comes alive I lower the gear set speed to 135 and as the plane slows I lower the flaps to 40. I arm the second CMD for autoland so I do not float past the numbers. The runway I am landing on is 6300 feet long. The plane flies a perfect autoland. The light above the autobrake switch comes on. The autothrottle shuts off and I engage full reverse thrust. I do not use my toe brakes until 60 knots. The problem is that it takes 6000 feet of the runway to slow to 60 knots. I tried the same landing using autobrake set at MAX with the same result. Just to compare, I did this landing with the dafault 747 in fs9 and it reached 60 knots with 2500 feet to spare. Any suggestions would be appreciated. Paul

You running version 1.3? Why would you wait till 60 knots to apply the brakes manually? Please do not judge anything by the default bird it does not equate and is not even the same type of aircraft. How much feul did you have when you landed? What was your VREF? How would one know how long it would take to slow such an object? Unless it is replicated in RL in the same conditions, weight, speed, weather, pax, rwy, slope, etc. etc. you would not get the same results..Best Wishes,[h4]Randy J.

Hi,Reading your story I must say, with the info you provided, that the aircraft performed quite normal, 39000 lbs payload makes the plane pretty "heavy" and a 6.000 ft stopway is to be expected. The autobrakes on the NG 737 aren't as powerful as the earlier models like the 737-300 which has a more powerful autobrake system. So nothing strange really..cheers,Bj

Paul,It's pretty basic physics that's needed to see if you are correct.For an ideal situation the below applies:Autobrake set to 2 means the deceleration will be 5 ft/s

Mats, you really were bored weren't you :)

:(Actually Nick, I really take interest in stuff like that. It's the engineer in me I guess. Cheers,
