Strange Altitude Assignment

Thu Feb 10, 2005 2:13 pm

I have been tracking a SwissAir flight from Los Angeles (LAX) to Zurich, Switzerland (LSZH) and the altitude is FL250 for some reason. They were assigned FL330 for the initial flight plan. 25000 feet uses up more fuel this way. Howver, I am pretty sure that they will reach a higher altitude as they go along.

Why is this? I never in my life seen this altitude.

FL250 is a commonly used altitude. Nothing at all unusual about it. The flight was probably leveled off at a lower altitiude temporarily. This is a common occurance. You may have as many as 5 or 6 level offs, depending on where you are leaving from, performance limitations, routing limitation, and traffic conflicts. It is extremely rare to climb direct to the higher flight levels in the US.

"It is extremely rare to climb direct to the higher flight levels in the US."

You mean it's rare to be cleared direct to cruise altitude upon takeoff. But climbing direct to cruise altitude is common; eastward out of SFO flights take off cleared to 15,000, and before they reach that they're recleared to FL230, and before reaching 230 they're cleared to their planned cruise altitude.

No, I mean exactly what I said. The situation you describe may be accurate for eastward traffic in the San Francisco area. It is not the norm through out the US. If I am going above 250, I usually have at least one level off.
