Wow. Nice. Our flows are an embarrassment.
I think the APU on the SuperDooperDugong burns more than that.


However, 380 MTOW is 569,000kg & we carry 520 people.
Max fuel load is upwards of 250,000kg depending upon SG.

This will make you laugh Salty! Your MTOW is almost 1000 times more than a Laser MTOW! You also carry 520x the human cargo! Max fuel in a Laser (Avgas) is a massive 62 litres (less than 45 kg), or 5,555 times the fuel load for you! Isn't it said somewhere that size doesn't always count? :oops:
Also, the only inflight service I could administer to myself would be perhaps scrambling for a barf bag if needed! Hey, real aerobatic pilots don't need those! :oops:

Ah, can you get off the runway in 6 seconds though?

Your fun count would be much higher than mine.
The thrill sorta rubs off at 3:30am when you've been going for 7 hours & you still have 6 more to go.

Yes.

Sideways if an outside engine fails below Vmcg.

:mrgreen:

Stu, is the last read out at the bottom left for vibration? And is it IPS?

Hi Dave, yes it is mate, I presume you mean what scalar units are used to measure vibration? The highest reading is shown on the flight deck in units and then they use a table to convert to MILS. The Airborne Vibration Monitoring (AVM) takes its readings from the N1 bearing and the fan frame compressor case. When Vibration indications exceed 4.0 units we have to consult the checklist.

Does this answer your question mate?

Thanks Stu, it does answer my question. Impressive to have vibration monitoring during flight. The ol' kingair gets an annual vibration check-up, unless there's been a prop or engine change. And IPS is the units we use, inches per second, with 0.1 being acceptable, but we get them down to 0.03 and smoother, well the analysis box we use does anyway.
