E190 on FLL-JFK!?
 

I received a 15-minute (no big deal) schedule change notification today, and as always, went to see if my seat stayed the same or if I was reconfirmed with an acceptable one.

To my pleasant surprise, I saw an equipment change. Instead of the usual 320, I'll experience the 190 for the third time in my life...very excited, but any guess as to why the equipment change? All other flights are 320.

is it me or do E190's fly faster?


--Russ :p

Would not be surprised, since it's a fully powered jet with less overall weight!

From airliners.net:

So, it looks like it depends on how much they're pushing the engines, but if both are at max power, then it seems that the A320 goes faster, although not really by much (only 13km/h)

I have this same feeling, too. Perhaps its more related to the flight paths/altitudes/routes though.

I didn't take a picture so don't ask for proof, but it must have been some strong tail wind to display 618mph on Channel 13 during my ORD-JFK flight on E190.


I remember my Florida trips usually averaged around 550mph on the E320


I could be wrong.

I never knew Mercedes E320 can go so fast! :D:D:D

But, I believe it regarding the 618mph on a 190...a westbound flight most often catches pretty decent tail winds. The fastest I recall seeing on ch. 13 was on a MSY-JFK flight about 15 months ago. I think we hit the 670mph range at one point, no joke.

Eastbound, in the winter, i use to constantly see speeds around 670-690 in the 320. Today I was supprised to see a JFK-LGB flight blocked at 5:05.

As for the 190, we do see it occassionally. If the inbound aricraft is extremely late and the outbound flight is booked under 100 they may add in a 190 if there is a free one sitting around JFK.

To the Delta 767 we where following in JFK this morning, if you are wondering where a huge, long rod from your aircraft went, check with our JFK MX Department as it found it's way through our right side main well tires. :mad:

There are two measures of speed in aviation, ground speed, which is the numbers you are all quoting, which include the velocity of the aircraft plus or minus the wind, depending on the direction of the wind.

Then there is what is known as "true air speed" which is what the specs in the post above referred to. This is the air speed of the ship regardless of the wind. This is a critical piece of data because the a/c's capacities are defined according to true airspeed, not ground speed.

All commercials airliners fly considerably below their maximum true air speed which is not safe to operate at for extended periods of time either structurally or mechanically.

The numbers shown on Channel 13 are ground speed numbers. That is how fast we are moving across the ground. Ground speed factors in the wind velocity as TWA stated above.

Thanks for the ground speed/true air speed info! I've always seen both terms on MS Flight Sim, but never understood it as good as you just explained it.

the Jet Blue spec decked out A320 is a Mercedes-Benz of aircrafts...


I'm guessing the other number you see on ch 13 is the sea level elevation.


JFK, LGA, EWR here show 5 feet, while Chicago was signifincantly higher.

I first picked up on that during a trip to SEA last year.

Westbound will hit headwinds most of the time. Eastbound will get tailwinds. That's the way the jetstream rolls. In the winter they can be very significant - enough to cause fuel stops westbound but still have the planes complete the r/t turn out and back in about the normal allotted time thanks to such a short return trip.

Seasons really do play an effect on the wind speeds... worse in the winter, better in the summer.
