A great little plane, but I'm curious why it has been restricted to 28,000 feet. Sure, there aren't many of them left, but still curious why the altitude restriction, the last ones I was on (all NWA), seemed to climb like they wanted to keep going up forever

Just a hunch, but they may not be equipped to comply with the new RVSM airspace that recently took effect, the floor of which starts at 29,000 and goes to 41,000. (RVSM allows for 1,000 foot spacing versus the previous 2,000 feet). If an aircraft is not RVSM equipped, it has to stay out of RVSM airspace, and 28,000 would be its max altitude...

If NWA does indeed have their DC-9-10 fleet certified for RVSM ops, the particular aircraft you were on may have been non-compliant that day due to an inter-related MEL item, and may have thus been limited for a day or two until the offending item could be repaired...

Makes a lot of sense.
What happens if an RVSM Aircraft encounters a snag in its Altitude measuring systems flying above FL280.Not considering stby Instruments.

If you encounter any onboard malfunction while flying in RVSM airspace that affects your RVSM legality, then you must advise ATC right away. You may not have to descend, but the airspace ATC uses around you will reflect your reduced reliability/capability.

There may or may not be one or two DC-9-10s still around. If there is one or two remaining they are not and will not be certified to fly in RVSM airspace.

It's likely it has to do with the age of the aircraft (by now most series 10s are at least 35 years old, with airframe hours to match). To prolong the fatigue life of the airframe, the permitted cabin pressure differential may have been reduced; in turn, this would restrict the aircraft's operating ceiling. I know such limitations have been imposed on other aircraft types as they reached high hours and cycles.

The RVSM airspace explanation is certainly another possibility. In either case, the DC-9-10 is unlikely to be the only type affected, as there are plenty of elderly and old-technology aircraft still in service.

Tonight, I was on a dc-9 out of FNT to DTW -- miserable weather, de-iced in FNT, then we were in the air close to 1 1/2 hours, landed on a very slippery runway in DTW (kudo's to the captain, beautiful landing). Then, another dc-9 to IND -- de-iced in DTW again, sorry, I don't remember the take off because I fell asleep, but I've been on many dc-9's at 36,000 feet (not the 10, granted)

- An hour and a half flight from Flint to Detroit? What kind of routing? Via Cleveland?  Wink/being sarcastic



Flying is the second greatest thrill known to mankind, landing is the first!
