I don't know why the plane stops in Edmonton. It could be not enough fuel due high headwind or some reason technical stop.

I checked their schedule and it is normally a non-stop flight FRA-SFO... good guess that it is because of headwinds. Extremely strong sw to ne jetstream. Bigjets info shows that it is a 747-400, and that should be able to accomodate non-stop even with the winds, but the schedule shows it as a 747-classic. Who knows what other possible factors could be at play.

The LH aircraft is a 747-400. It is scheduled to arrive at SFO at 1500. No word why it diverted.

Sounds like the aircraft might have been on a reclearance flight plan. Is it normal for LH to file reclearance flight plans though?

Most likely a medical diversion or an alarm involving some kind of possble security threat to the aircraft or crews.

YEG gets a couple non-scheduled stops each month and since DLH has a number of flights right over the Edmonton ARTCC daily, it makes total sense.
They even stopped at YYC one time.



Chance favors the prepared mind.

Ar385,

well, I will attempt an explanation of what exactly a reclearance flight plan is. Unfortunately I am missing a couple of proper English words for my explanation.

Sometimes you (as a flight planner) are in the situation that with the offered payload you wouldn't be able to make it nonstop to your destination without exceeding the maximum takeoff weight. Well, then you can either leave payload behind or file a reclearance flight plan.

1. First a "normal" flight plan to the intended destination is filed with the maximum allowed takeoff weight.
2. Then is determined how much payload would have to be left behind if you actually load the "required" fuel to your intended destination. If the payload which would have to be left behind is less than your required contingency fuel (5 % of the trip fuel) you can file the flight plan as reclearance flight plan.
3. Then you file a "normal" flight plan to a destination enroute (called the reclearance destination) to which you would be able to carry the extra payload without exceeding your maximum allowed takeoff weight. Enroute to both the intended destination and the reclearance destination you have to file a reclearance point which should be at about 90 % of the distance between your origin and intended destination.
4. If you still have some contingency fuel left once you actually reach the reclearance point, you may use the remaining fuel for the trip to your intended destination, if the following is true:

you still have the required trip fuel from the reclearance point to the intended destination aboard
+ 5 % contingency fuel
+ enough fuel to your alternate destination (in case of bad weather or similar at your destination)
+ the required holding fuel

If this is not the case, you have to fly to your reclearance destination.

Example:

For the flight FBA001 from EDDF to KORD following fuel requirements are determined:
trip fuel: 100000 EDDF-KORD
contingency fuel: 5000
alternate fuel: 3000 KORD-KMKE
holding fuel: 2000
takeoff fuel: 110000

If you have a maximum allowed fuel quantity of 107500 you would have to leave 2500 payload behind which is less than the contingency fuel (5000) and thus you may file a reclearance flight plan.

Lets assume you chose CYUL as a reclearance destination with CYMX being the alternate for that reclearance destination and file a flight plan:

trip fuel: 90000 EDDF-CYUL
contingency fuel: 4500
alternate fuel: 2500 CYUL-CYMX
holding fuel: 2000
takeoff fuel: 99000

Lets assume that the reclearance point is BAFIT and lets assume that we found out in the filed flight plan from EDDF-KORD that 85000 fuel is necessary to get to BAFIT.

From BAFIT to KORD you determine the following figures:

trip fuel: 15000 BAFIT-KORD
contingency fuel: 750
alternate fuel: 3000 KORD-KMKE
holding fuel: 2000
total: 20750

Assuming that FBA001 will not use more than 85000 to BAFIT and that at BAFIT at least 20750 will be required to continue to KORD your minimum take-off fuel - when filing a reclearance flight plan - is 85000 + 20750 = 105750. As we have learned we can load a maximum of 107500 fuel so it is safe to file a reclearance flight plan.

Well, that's it. Actually I thought it would be a bit easier to explain a reclearance flight plan... Hope you at least understand basically what it is all about.

Iberia340600 - as you can see in the line

ESTIMATED TIME OF ARRIVAL 1249 SFO

(just below the "TOOK OFF 1126" in the 7th line) of this Amadeus-output, the flight was originally scheduled as nonstop to SFO and was, for whatever reason, diverted to YEG. Otherwise, that line would have read

ESTIMATED TIME OF ARRIVAL 1249 YEG

(obviously with some other time mentioned).

Leskova:

Good point...but...I went back and checked on the info and if you look at the PLANNED flight info...the scheduled times are as follows:

ARR DEP
FRA 1010
YEG 1200 1245
SFO 1500

In my opinion they may have inputed the arrival city incorrectly. How could the ETA to SFO have been 1249 when the STA is 1500? Maybe it was just a scheduled flight for that day. Dunno...looks wierd to me.

Iberia 340600, I guess they put that in there when it became clear that the plane would be diverting - I know, sounds a bit like a longshot, especially when you consider the precise timing of 12:00 until 12:45, but: about a week ago a LH flight from FRA to ORD was diverted to, if I remember correctly, MAN - and that was displayed identically in the DO-Display, as if it had been a planned stop in MAN.

I'd say that the ETA of 1249 in SFO results from the fact that the plane is usually scheduled to arrive at 1230.

But I'll definitively agree with you - the way they display it in the DO-Display does look strange, as if the whole thing indeed was planned in advance...

But, considering the fact that LH455 from SFO to FRA on 01NOV was supposed to leave - according to DOLH455/01NOV - at 14:30, but didn't make it out of SFO until 16:30, I'd say it really was a diversion to YEG.
