WARNING!!! Suspect Flights in our Schedule

Postby David Vega » Tue Jan 24, 2006 8:04 pm

Flyer beware! :twisted:

There may be some flights with block times that need adjustments. Unfortunately after mass producing over 1500 flights, we don't know which ones are the bad ones. So, if you're going to fly, please estimate first what your block time should be. If the flight plan estimation doesn't match yours by a lot, then this is a suspect flight.

Please email me the details and we'll take care of it.

Dave,

I have recently flown some flights which I believe need adjustments in their block times. They are:

5104 EBBR - DAAG BLK TIME 2:17
5119 DAAG - EBBR BLK TIME 2:21

To meet these times, avg speed would have to be 450 mph. That is really not possible on this short of flight. Note that in actual real life the Air Algerie nonstop times are 2:35 and 2:45 respecively.

5172 EBBR - LKPR BLK TIME 1:11
5185 LKPR - EBBR BLK TIME 1:15

Non stop block times for scheduled airlines on this route are 1:25.

Finally, I flew flight 549 UUEE - EBBR. The distance listed was 1484 which is about 69 nm further than actual. I did fly the suggested flight plan.

You guys have done a great job with these schedules and am really enjoying flying them.

Roy,

Thank you. Reviewed all the flights and made adjustments where appropiate. Most airlines change their block times periodically based on many factors. For example, heavy ground traffic during certain time of the day would extend block time. We have average taxi time information for most heavy airports in the US, but unfortunately not for anywhere else. For those airports, I've used an average departure and arrival taxi times.

Regards,

Dave Vega

ZBAA - EBBR, Flight 537

Postby kenyapilot » Thu May 18, 2006 12:15 pm

Dave,

I was getting ready to fly to Beijing and back, noted the flight to was 4411 miles and then was surprised to see the return at 7927 with a flight time of 16 hours. I have done the route on FSNav and it is only 4395, so something is wrong here. Please look at this route and adjust as necessay.

Thanks.

Roy,

Which flight number? This would make it a lot quicker for me to find, fix, and post.

Thank you Roy. Done. Flight 537 now has corrected values. The new route has an average flight time of 10:00 hours. That's 6 hours less than the previous route. Thanks for the correction.

Dave,

I flew 8053 shows a Blk time of 3.0 but that seems a little high. I actually flew it in 2.2.

28/5/2006 8053 CRJ2 N805SL KISP KATL 6,033 769 2.2 -0.8
27/5/2006 8052 CRJ2 N805SL KATL KISP 6,377 773 2.1 0

I have flown flight 2129 in a 767 which has an estimated time of 02:40 which appears to be too long for this flight the same route which is flown in flight 2145 in a 737 is twenty five minutes less and seems to be more in keeping with the time it would probably take for this flight. I tried to stay within the time limits for 2129 and flew it at .74 mach for quite a ways and even took the long approach and still was to early. :cry:

Al, good catch. The block time should've been closer to 2.4. It's now adjusted and your fltrep regraded. You're now on time for this flight.

How do I know what the block time should be? You and anyone else can use the same method. Go to http://www.fltplan.com and log in with user id 'sax' and password 'pilot' (in both cases without the quotes). Select the link labeled 'Quick Info' and then select airplane, departure, and destination, and see what is the average flight time. Add 12 minutes to taxi out and 5 minutes to taxi in to the flight time and you have your block time. If this block time is way different from what's published in our schedules, let me know and I'll review and correct when necessary.

Have fun

I have recently flown both flt# 152 and # 163 they are the same routes flown in reverse directions but their times are considerably different, wonder if you could give it a look see.

Thanks Al,

They are slightly different routes. KTPA-KPHL distance is aprox 862nm and KPHL-KTPA is 842. The other difference is the direction of flight. KTPA-KPHL is an easterly route, normally with the prevalent winds. Coming back, you would normally have a head wind. http://www.fltplan.com, using a direct point to point route, calculates KTPA-KPHL today at 1:57, and KPHL-KTPA at 2:08.

Have a super 2007!

Dave

Yes I'm still alive :shock:

Also, the hardest thing about making our schedules is that it is static over the entire year (re: winter winds, IFR, etc.) so there has to be a balance in there to keep the majority of our flights on time.

Dave,
Was about to do flight #5223 uacc-ebbr when i noticed the block time is 1.7 more than the reverse flight which is 5.5. I loaded suggested route into fs9 and found it around 230 miles shorter than the expected mileage but on a par with the 2,500 mileage for the reverse leg which i had flown. I checked to see if any other pilots had flown #5223 recently and noticed sax680 did it(differing route) on 7/9/06, 2200 miles, blk 6.0, actual 6.2. Could this be a suspect flight? :? :?

Dave, I'll take a look. Preliminarily I can see that there's going to be a difference in time based on flight direction. EBBR-UACC is also likely to have tail winds, where UACC-EBBR should expect head winds. Will post a better answer as soon as I finish the setup of the Baghdad, Iraq Regional Office of SunAir Express. :)

Dave,
Did flight 19/03, 2499 miles, block of 6.2, same as sax680 did it.Yes there were some headwinds but i think 7.2 maybe too high a block time??

Thank you for the info. Flt 5210 and 5223 adjusted. Your FLTREP for 5223 is also updated.

Another boring day at work. Looked at flights in the logbooks that were in the red (1/2 hour or more early or late) and saw which were flown by two or more pilots. Here are some flights with suspect schedules.

Flight 59 WSSS-EBBR is scheduled for 12.8. Jones (SAX464) did it in 11.9 (-0.9) and I (SAX714) did it in 12.2 (-0.6). Fltplan.com says 11:47 flight time. Not sure why Brent (SAX680) took 13.3 (+0.5) to fly it.

Flight 161 KJFK-KTPA is scheduled for 2.9. Jones and Tilley (SAX741) did it three times in 2.3 (-0.6). Fltplan.com says about 2:11 - 2:30 flight time depending on winds.

Flight 217 EDDF-KATL is scheduled for 10.3. Jones did it in 9.3 (-1.0) and 8.9 (-1.4). Fltplan.com says about 9:03 - 9:24 flight time depending on winds.

Flight 6010 LSZH-KORD is scheduled for 10.2. Remynse (SAX747) and Becker (SAX054) both did it in 9.7. Remynse was 0.6 late, Becker was 0.5 early (schedule must have changed between the time the two flights were flown). Fltplan.com says about 8:58 - 9:17 flight time depending on winds.

Flight 9566 EBBR-EGPE is scheduled for 3.2. Brent did it in 3.0, then 0.7 late, and Woodward (SAX728) did it in 2.5, now 0.7 early. (Must've been a schedule change between the two flights.) Fltplan.com says 1:51 flight time.

Flight 9570 EBBR-ENBO is scheduled for 3.3. Woodward did it in 2.8 (-0.5) and I did it in 2.6 (-0.7). Fltplan.com says 2:36 flight time.

What's this flight 9999 that's suddenly appeared in the Route Search (and one or two logbooks) and how is MMTG equal to Boston Logan Int'l (in the List of Airports)?

P.S. Why is the Forum so super-duper slow today?

9999 is a flight # that is used for the monthly flyins. It records time but does not affect on-time performance.

I believe the LSZH-KORD flight did have a duration time change from when it was initially loaded.

I had some trouble adding the new airport MMTG for the last flyin. Looks like the database copied something from the KBOS record entry and made two Boston airport entries. I will have Mr. Vega take a look at it. I'm sure he will be able to fix it. In the mean time I deleted the MMTG Boston airport but it also deleted the KBOS Boston airport entry.

As for the slow forum, it's probably due to high demand on the server. Guess we are just too popular. :wink:

Dave Vega,

I've found quite a few schedule conflicts (planes in two places at once, too short time spent at the gate, etc.). I'll email you a list of my findings and a spreadsheet of proposed corrections.

Yes, have a big load of changes to make. I'm way behind. Unfortunately work is keeping me very busy. I should be able to update the entire schedule soon with a major revision work one by another of our Captains. For now, believe 161 is corrected.

Dave,
Flight #9570 ebbr-ebno has been mentioned before, i did it on feb 1st in 2.8 hours way quicker than the scheduled 3.3.
Pilots 728 &714 have done it in 2.8 & 2.6, Fltplan time it at 2hrs 36m, this flight defnitely needs adjusting. Am expecting return leg #9573 will probably be a wee bit longer than the 2.8 published block time.
