Easiest way to find out your Top of Climb for Navlog?

[CC268]

Hey guys,

I am just wondering how you guys go about finding your Top of Climb for your Navlog (when doing it by hand - I realize most of your probably don't do this by hand). Finding TOC itself is easy (how long it will take to get there), but trying to figure out where it will be in relation to your waypoints can be tougher...

GS in climb * time = distance.

No, the easiest way is to climb at 500 FPM (above TPA). Then, it's 2 minutes per thousand feet. Then, it's Ed's formula. If there is no wind, you can use TAS instead of GS, but there usually is some wind.

If you want to climb at constant airspeed or at Vy, your POH has a table for that. Just make sure you meet its assumptions, or compensate for exceptions.

Or if you have the power, 1000fpm. I can usually achieve that through 5000'

I use Garmin pilot. I don't think it does a very good job of doing this calculation for you. When I was planning out my cross countries for my private, I would get a clean sheet of white paper, and plot out the altitude profile for my flight. Then I'd calculate the time to climb for each leg, the ground speed, the elapsed time, the fuel consumption. I'd do each direction on its own clean sheet of 8.5" x 11" paper. My instructor loved this. At this stage of your training, it's all about demonstrating that you understand the principles that go into planning the flight. To be completely honest, since I got my private, I've never done this again. The ballpark figures I get from Garmin Pilot are close enough, and I always make sure I have two hours more fuel than I think I need, but the furthest I've ever flown from home was to Safford (KSAD).

This is going to change for me when I fly up to SLC this fall. I'm definitely going to be spending some more time planning that flight.

This is how I remember it:
