How many seconds does it take for a B737 to reach 0 to 60 mph ? Does anybody out there know?

between 20-30 sec.
depending on weight outside air temperature.
The B737 takeoff will be executed a lot with reduced N1 procedure so takeoff thrust sometimes is only 88 or 90%. V1 Vr V2 are also different in every flight.
but 20 to 30 sec is good!

I have checked the notes I usually take when flying as a passenger, and my experience for the take-off roll in 737s (from releasing the brakes until Vr) on 48 flights in 737s varies between 22 and 35 sec depending on TOW and environmental factors. For most of the flights on a short hop between BRU and SXB with a scarcely laden kite, acceleration to Vr would be in the low 20ies for a --300 or -500 series 737.

To SQ325: Although I do not think that our contributions answered Wardialer's question, as the acceleration to 60 mph implies that he seemed to have looked for a comparison to car performance figures.

To Wardialer: If my assumption was right: I know about tests of a German motor magazine (Auto, Motor und Sport) from 1980 or 1981 where they had a competition between a BMW 850 sportscar and a German Air Force Lokheed F-104 for the acceleration ratio. Maybe you can get hold of a copy.

I have a video of takeoff roll (infact, I have 3 complete flights recorded) in a B737-300, in December of 1994. The temperature outside was about -5 degrees celzius, and I measured the time needed for aircraft to reach 80 KTS, V1-Vr (a/c was half-loaded with passengers):

80 KTS - 15 seconds
V1 - 27 seconds
Vr - 27-28 seconds (almost instantly after V1 call)

I don't know the exact t/o speed (Vr), I think speed was 134 KTS - it was long time ago (1994) and we shoot from hand and camera was rocking like hell so we couldn't zoom sharp on the airspeed indicator. V2 speed, as I recall, was 143.

I think that the time needed to reach 80 KTS will give you some information about 737 acceleration Smile But, that depends of temperature, wind, runway condition takeoff weight etc...

Best regards

depends on the weight

Literally empty 732 (20 pax and luggage)with 10,000kgs fuel with JT8D-9A could do 0 - 60mph in about 20 secs.
A JT8D-17 could make that into 17 secs... It was fun !


When losing situational awareness, pray Cumulus Granitus isn't nearby !

I seriously doubt it takes a 737 20 secs from 0-60 mph.

Most ailiners, including larger wide-bodied planes that I've seen/been on, take around 35 seconds to T/O. I'd assume the entire time spent at T/O for a 737 would be 25 seconds. So, assuming a T/O roll Vmax=150mph, it would take no more than 10 seconds to reach 60mph.

I know Concorde takes 26 seconds and it accelerates to 250mph!
