TALPA PIREP

Here is a story shared by one of our 757 Captains on a recent trip for your benefit.

Here's the details of our TALPA divert:

Flying up to Kxxx in late November, ATIS was calling TALPA braking action of 3/3/3, which equates to medium braking action.  Winds were gusty and almost a direct cross. Somewhere around 16 knots steady gusting to 25+. Kxxx was experiencing a blizzard and the runway was covered with snow, the plows were doing their best to keep up. On the way in I ran the numbers for landing in the APS and input the TALPA 3/3/3 for the runway condition. We were surprised to see that the APS was giving us numbers, and a max crosswind limit for landing of 25kts. We had it in our brains that the max medium braking crosswind limit was 15kts. We double checked the limitations section of the PHB to confirm the 15kts, and decided to divert to Kxxx due to max crosswind limits.

B757/767 (PHB):

After we got on the ground, I did some more digging and found the new crosswind limits chart as it relates to TALPA numbers buried in the bulletin. This was a little hard to find since there are two bulletins that relate to the new APS, and each one has a crosswind chart in it. The newer bulletin has the new crosswind limits. We confirmed the new crosswind limits with a standards pilot and launched back to Kxxx, this time able to land.

Use the TALPA bulletin to determine your wind limits:

B757/767:

For takeoff the next evening, the weather was very similar.  

ATIS was calling TALPA 3/3/3 with 80%of the runway dry snow <1/8 inch, and 10% ice. Crosswinds were also high. When running numbers for takeoff, I noticed that there is no ability to input TALPA numbers in the takeoff section (only in the landing section).  So we had to input the descriptor instead. The closest thing we could find was dry snow <1/8 inch. The numbers crunched, however the max crosswind limit was stated by the APS as 25kts. However, if you look at the new crosswind limits TALPA chart, the max crosswind limit for 3/3/3 is 17kts. No ability to put this in the APS was definitely confusing.  

Key takeaways:

1-Every FedEx airplane has new wind limitations and it is in the TALPA Bulletin not your PHB—The PHB wind limits have been superseded by the TALPA bulletin.

2-There are different wind limits for takeoff (less than) and landing (greater than) as a result of the TALPA bulletin—The APS displays them.

3-There may be APS errors for takeoff crosswind limits—trust but verify.

4-APS landing calculations allow RCC inputs—takeoff does not.

5-These are max limits—you determine what is safe under the reported conditions.
6- This InFO serves to heighten awareness of the TALPA initiative’s activation date and to highlight forthcoming amendments to the AIM and AIP.
