How many Gs can a 747 take?
Civil aircraft certification requirements for airliners demand normal operations be possible up to 2.5g and down to -1g in clean configuration up to design manoeuvring speed, reducing above that speed.
What limits an aircraft service ceiling?
When you can no longer climb with more than 100ft per minute (for propeller aircraft) or 500ft per minute (for jet / turbofan aircraft) you have reached your service ceiling. If the aircraft maximum altitude is determined by thrust, the absolute ceiling will take very long to reach.
How many 747s are still in service?

What is the difference between absolute ceiling and service ceiling?
The absolute ceiling is the altitude at which the (maximum) rate of climb goes to zero. The service ceiling is the altitude at which the maximum rate of climb is 100 ft/min. ( 0.5 m/s) for piston powered aircraft or 500 ft/min (2.5 m/s) for jet powered aircraft.
What determines aircraft service ceiling?
Service ceiling is where the rate of climb drops below a prescribed value. However, some performance charts will define the service ceiling as the pressure altitude at which the aircraft will have the capability of climbing at 50 ft/min (0.25 m/s) with one propeller feathered.
