P. NW 305's at low fall honoring hold at 6,000. C. (Unintel). P. Approach from NW 305. We find that your low fall interception's going to put us into ah. . .some overcast and some icing conditions here. We'd like to hold. . .ah. . if we could hold at about. .ah. .20 PME 15-20. .something like that if that is not going to be in your approach pattern. We'd appreciate that. P. NW 305. Should we start to climb a little higher also? C. NW 305, turn left heading 130 and then you can talk about that altitude later. P. Okay, we'd just as soon stay 6, if we can if it's smooth. C. Okay, fine. P. Seattle Approach. NW 305. We're still at 6 and. .ah. .we're about 22 PME out on 307 radio. Or ah, we'll be pulling back on the 307. Ah. .we could just find ourselves a place to hold out here somewhere in the 20 PME range would be okay. Looks like it'll keep us in the clear and smooth. C. Okay, fine. If you want to hold on the 307 radio between 15 and 25 PME would be fine. P. Okay, we'll. .ah. .we'll do that. C. NW 305. Say altitude. C. NW 305; verify altitude at 6,000.

P. Verified at 6. C. Did you call 305. P. 305. Negative. P. Approach, NW 305, ah. .a little rain up over here. We'd like to hold it at about. .ah. .turn back on the radio now and go out to about, oh, 30 would be a little better. C. It'll be okay. P. NW 305. Seattle Approach. Roger. C. NW 305, verify you're still at 6,000 please. P. Holding at 6,000. P. I don't know, I think it's free. .free to call us. .ah. .nobody's giving us any trouble up here. He's in the back. C. We won't bother you unless we absolutely need to. C. NW 305. Approach. Are you ah. . .in (unintel) conditions or what are your flight conditions now? P. Well, we're ah. .we'll be up higher. .ah. . we're just about. .looks like the scattered layout here is about 5 to 55 variable. C. Okay, if you get too far beyond low fall, it will be necessary to go up a little higher than 6,000 for a minimum terrain (unintel). P. Okay fine. We. .ah. .plan not to take it
beyond low fall here, we get little bumps once in awhile. This ends Reel #1 of the re-recording. Time at this point is approximately 0011 Greenwich.
