737-300 No bleeds T/O thrust increase
How much more thrust can one obtain by doing a bleeds off take off on a 737-300 ? How many percent increase in N1 % can one get ?
By the way, where do we find such information? Thanks! |
Not sure about the thrust increase, but I seem to recall on the 737-200 bleeds off resulted in about 1000kgs extra weight to be lifted off the runway.

You can find the info on the 737-300 QRH Quick reference handbook....
|
AFAIK, the 'standard' Boeing 737 3/4/5 increase is 600kg, unless your performance guys calculate SPECIFIC aerodrome data when it will be more.
N1s are typically 1% higher bleeds off. |
weight increase
Thank you so much for all the postings. Managed to find the 1% increase in N1 in the QRH. But what about weight increases? Where can we get those information?
|
That depends on the runway analysis charts for the specific airports...
I'm afraid there's no fixed value, and as BOAC says it's in the range of 600-900kg more or less. |
