Salt Lake 2 Departure

Let's get straight to it...

The question is:  Can we do the Salt Lake 2 Departure (SLC2.TCH) in the Seminole?  How about with only 1 engine operating?

Let's take a look at the charts:


When looking at the departure procedures, we see that we need to calculate performance for field elevation, 7800 MSL (Rwy 35), and 8300 (Rwy 17), so we need to see the temperatures for these altitudes...

Field:  18
7800:  14
8300:  13

We then have to check the Seminole performance charts for max gross weight to ensure that we can successfully complete this departure:

-At field elevation, we see that we can climb at 900 fpm.
-At 7800 MSL, we can climb at 650 fpm.
-At 8300 MSL, we can climb at 550 fpm.

With these conditions and both engines operating, we can do the Salt Lake 2 departure from RWY 17/35.

***A key thing to check is the one-engine inoperative climb rate, which in this case is 0 fpm. TAKE NOTE that this is at field elevation, so as we got higher it would be even less. We can see that in the event of an engine failure, we would not be able to climb at all, and would have to take an alternate plan of action - which would most likely be to land as soon as practicable.
