HI All Been flying the 737ngx for a few flights. I have noticed in every flight I'm getting this warning horn after passing 10 000 ft and it continues as I climb Any ideas there is no physical warnings except for the sound of the horn repeating Look forward to responce Regards Craig

This means that your cabin pressurization is wrong. Im guessing that you havent set up your air panel properly after starting the engines.

Or you've left the doors open!

Have you done the tutorial flight?

Yep cabin press warning. You did something wrong

It's the warning that your cabin altitude is too high - the aircraft is not properly pressurized. Before takeoff, insure that all doors are closed. On the overhead panel pressurization controller, check that the mode switch is in AUTO. Set your planned cruise altitude in the upper window, and the elevation of your destination airport in the lower window. After engine start, make sure that both engine bleed air switches are ON. Turn APU bleed air OFF. Set L PACK, R PACK and ISOLATION switches to AUTO. Set both RECIRC FAN switches to AUTO. Finally, set the TRIM AIR switch (one panel above the pack controls) to ON. That should take care of the problem.
