Boeing 727 in flight at Mach .85 and also close up of LED extension and retraction.

Boeing 727 is a very good aircraft there can last long.

I like this - thanks for sharing...

The 727 burns around 9,000 pounds/hour at cruise speed. Hi speed and down lower, we were probably burning 10,500/hour

[archer49d]

How many lbs an hour are you burning cruising down there?

[mawkbuff]

@archer49d Around 10,500 pounds/hr total.

[SandburgSpartans]

that's the cruise speed of a 787. 647.025993 mph

[mawkbuff]

For us, it's a bit different reasoning. Our fastest true airspeed is at 26,500 feet in the 727. I believe this day we were cruising at 27,000 feet and clipping along nicely just shy of Mach .86

In the tropics you'll try to cruise at waist level of thunderstorms because that's the narrowest point. Best levels from FL250 to FL280 of course using the aboard radar extensively.

why such a low cruise altitude??

[lufthansa330pilot]

@maplemanz ya doesnt its save fuel going at fl35 or so? or was the airspace overtheir full?

[mawkbuff]

@lufthansa330pilot Higher is better, but I think it was a shorter stage length, so we stayed low.
