Cruising Altitudes?

Tue Feb 10, 2004 8:00 pm

Probably not the most interesting topic, but just wondering what is the highest cruising alt you have flown and on which flight?
Mine is FL400, on Astreaus 737-700 KOS>LGW.

T500.

FL390 on a Virgin B744 SFO-LHR.
Why do they always stop there?? Crying I'd love to see FL400

757KSLC...
FL400 is not really a legitimate cruising altitude here in the States at this time, but it will become one a year from now. Currently, the standard IFR cruising altitudes are based on the hemispherical rules. At FL290 and above, aircraft are given 2000' separation. For example, on easterly courses, your altitude assignments would normally be FL190, FL210, FL230, FL250, FL270, FL290, FL330, FL370, FL410, FL450, or FL490. For westerly courses, you would get FL180, FL200, FL220, FL240, FL260, FL280, FL310, FL350, FL390, FL430, FL470 or FL510. Actually, the rules extended up to FL600, but I know of no currently operational civil aircraft with a certified ceiling greater than 51,000' - so it's basically a moot point. These altitudes are known as "hard altitudes" - I'll explain more later.

Like everything else, there are exceptions to just about every rule. It is not at all uncommon to be able to get "wrong way for direction of flight" altitude assignments - for example, say you want FL410 instead of FL390 on a west bound leg. ATC is usually quite accomodating, especially at altitudes of FL410 and above.

Is there a way for you to have actually been cruising at FL400 on your west bound flight? Yes. What the captain probably requested is a "block altitude" assignment. For example, s/he probably requested a block altitude of FL390 through FL430; if ATC grants this, you could legally pick any altitude between 39000' and 43000' to cruise at. Block atitude assignments aren't quite so common, but they're not unusual either.

Just about everything that I mentioned previously is about to change next January when ATC impliments DRVSM (Domestic Reduced Vertical Separation Minimums) here in the States. (These have been gradually introduced world-wide for a few years now.) Basically, these new rules require special aircraft and flight crew certification in able to operate in the airspace between FL290 through FL410. When the new rules are enacted, there will be 1000' separation up through FL410 instead of the current FL290. The easterly altitudes will become FL290, FL310, FL330, FL350, FL370, FL390, and FL410. Westerly altitudes will be FL300, FL320, FL340, FL360, FL380, and FL400. You can see that these changes will double the capacity in those altitudes where the vast majority of jets hang out.

Now, to answer the original question...

In my case, I spend most of my time at FL390 and above. Typically, we flight plan initial crusing altitudes of FL390 or FL410. We go to FL430 on nearly every coast to coast trip regardless of direction and FL450 isn't unusual either.

AFAIK I've never hit the FL400 mark...I guess FL390 a bunch of times is the best for me...and GA-wise my highest is 11,500' in a Cessna 172

My best is FL420 in a BA 744 from YUL-YYZ in April 2003. Was really strange! All the way up just to come right back down! Big grin

ATA 101 going from LGA to LAX via Indi. Pilot announced that we were at FL390.

Comming back on ATA 102 from LAX to LGA via Indi. not sure but we were pretty damn high. Anyone have further info would be great.

Hi guys.

I've flown at FL 390 several times. The last time I was at 39,000 feet was from Miami (MIA) back home to Toronto (YYZ) on an American Airlines Fokker 100.

I made it up to FL 410 once on a flight from Ft. Lauderdale (FLL) to Toronto (YYZ) on an Air Canada 767.

It's to bad nobody will be making it up to 58,000 feet anymore (at least for a while) on a commercial flight!  Sad

Reading these posts got me curios; I realize the bizjets can easily get in the upper 40's and even up above FL510, but aren't most airliners (Concorde excluded) limited to FL410? The 737NG is capped there and I think all Boeing's are as well, anyone know for sure? Any Airbus drivers out there?

For the most part it has to do with the pressure system on commercial jets.

Most biz jets are designed to fly high to avoid commercial traffic.

Also, what is currently the most highest flying biz jet on the market?

David...
There's a whole gaggle of bizjets certified to FL510 - it's not really all that unusual at this point. The certification requirements change above FL510 so I doubt that you will ever see anything certified above FL510 unless there's a new SST or SSBJ.

Hmmm. I had thought that the 737NG's had a ceiling of FL390?

ANd arent the "Motor Fokkers" restricted to FL350?

All models of 747 are certificated to FL 451 (45,100 feet) -
707s and 727s are certificated to FL 410 (41,000 feet) -
xxx
These altitudes are rarely achieved on regular flights.
At full takeoff gross weight, we barely can climb to FL280-290...
When flying with the 747s, we are generally at FL 370-390 at end of cruise.
The weight of the aircraft (payload) prevents us to climb any higher.
I have been very rarely at FL 450 with a 747.
One exception, with the 747SP, we were often at FL410-430...

very interesting trip, you actually feel kind of high.

Now the 400 never go over 39,000.

Indianguy, service ceiling is not how high a plane is legal to fly. Service ceiling is the maximum density altitude at which the airplane can climb at 100 feet per minute, and varies with weight and temp. So it still may be possible.

Highest I been at is FL420 Korean air 744 enroute SEL-ORD.

However domestically within Australia FL390 and the highest on a turbo prop Dash 8 is FL210

LGW-MCO Virgin 742/744, probably between FL350 and FL400 not too sure?!

LGW-MAN British Airways 734, we hit around FL190 and FL250
