Highest Altitude On A Commercial Flight?

Fri Oct 01, 2004 9:30 am

Returning to LHR from PHL on a BA 777 this week, the PTV 'airshow' indicated the aircraft's altitude as 43,000ft. This is the highest altitude that an aircraft I've been on has reached. Has anyone been on a regular commercial service (excluding Concorde), where the aircraft has flown higher than this?

I've flown at FL410 on 757s a few times, but never higher than that.

I'll bet no paying passenger has been higher than FL430 on a subsonic airliner-- I doubt that any is certificated to go higher than that.

410 is it for me, too. I didn't know a regular commercial jet ever went higher than that.

The most surprising plane to cruise at that altitude that I was on was a DL CRJ, believe it or not! It was from Wichita to Cincinnati, and we went up to 410 to go over a storm.

My first time at 410 was on a DL 767-200 - The Spirit of Delta, in fact - on a flight from SEA - ATL.

I know the certified ceiling on the 747-400 is 45,000ft. and assume at times they have flown that high, which would be awesome. Hop in a Citation X, Learjet 45, or Gulfstream V etc., you could cruise around at 51,000ft. however, the time of useful consciousness at that altitude is probably around 5-6 seconds during sudden decompression so it wouldn't be the safest of ideas. I believe 747SP's routinely flew above 40,000ft. but I'm not certain about that.

I've been at FL430 in a B744 before. I can't remember which flight it was though..... I don't think I've flown any higher than that.

Who decides the FL, the Captain?

I think it depends on the Flight plan, and also based on the calculations of the fuel. Usually, a plane, when it has just taken off, it will cruise at a lower altitude, then as the fuel gets less, which translates to less weight, it will go higher. But the captain does have a decision, e.g on emergencies. But most of the time, it depends on the airway used during planning

My highest altitude was FL 410 on a NW 752 between MSP-DTW, with second place at FL 390 going from MSP-LAX as well as DTW-MEM, both on NW.

In 1999 I flew SIN - MAN onboard an SIA 747 and the display in the airplane read just under 45,000ft.

The ceiling for the 747/747-400 is 45100. The limit is the ability of the aircraft to make an emergency descent in 4 minutes or less. In fact, if I remember correctly all 75/76/777 are also 45100.

As far as selecting the flight level, ultimately, it's up to the captain. However, the flight plans are normally run to get you the optimum flight level. Plus, the FMS also provides optimum and max flight level for the given weight and temp. On the 400, ideally, you want to fly +-2000 feet of your optimum flight level.

Got to FL410 on a SAA 747SP on a flight from JNB (elevation 5,577ft) to DUR (elevation 25ft) and the flight time was less than an hour! Had a jump seat directly behind the captain and feeling that thing climb was awesome.
