confusion about STAR into KORD

Recommended Posts

Flight from KMSP to KORD, FL 330, FYTTE5 ZZIPR transition for arrival to RWY 28R. After passing ZZIPR (don’t recall the distance) received clearance to cross FFYTE at 5700, then descend via the FYTTE5 arrival. 

It seemed, first of all, that an altitude of 5700 was kind of strange, especially given that the FYTTE5 arrival calls for a hard altitude of 11000 for that intersection, and also specifies 300 kts for landings to the west. My 737-700 had to just about fall out of the sky, and even at that could not make 5700 feet at 250 kts. I received a Descent Path Unachievable and Unable 250 kts message on the FMS CDU.

Flew this route twice, and received this clearance both times. Is there a logical explanation for it?

Can't be sure without looking at the log file, but in the scenario you describe, you should have been cleared to "Descend to 5700 via the FYTTE5 arrival with the ZZIPR transition for the ILS to Rwy 28R at Ohare International..." or something similar.

This clearance is to follow the altitude and speed restrictions published in the STAR to descend to 5700.  

If your aircraft call sign is designated as "Heavy" then the 250 kt below 10000 ft speed restriction should have been lifted to 280.  Be sure your call sign has the "Heavy" checked to get the higher speed.

If you could email the P2A Log file to admin@pilot2atc.com, I can have a look and see if something went wrong.  

P2A Log files are located in: 
C:\Users\<UserName>\AppData\Roaming\P2A_200\Logs 
where <UserName> is your PC user name. Portions of the path may be hidden by default, so be sure Windows Explorer has Show Hidden Items checked in the View tab.
A new one is created each time you start Pilot2ATC, so if you take the most recent one when you have the error, you should have the correct one.

Thanks. I will refly the route. It is possible that it is as you say and I misunderstood what ATC told me. Otherwise, will send you the log.
