ASE climb requirements

[Farmer]

I need a little help with 135 climb requirements and want to use Aspen as an example.

Lindz 4 Departure:

Note: Take-off runway 33 3100-3 or 1000-2 with a minimum climb of 460' per NM to 14,000.


Ok the question,

What weather do you need to use the 460' per NM compared to the 3.3 climb?

In other words is the chart saying that with anything above 3100-3 or 1000-2 you have enough vis and cloud clearance to climb "visual" using 3.3 climb gradient and no longer need to meet the 460' per NM.

Hope this makes sence.

You got me confused actully. I have no idea what you mean by "3.3 climb." You don't need to meet a climb gradient if the weather is above 3100-3. If the weather is below that value down to 1000-2 thats the range in which you need to meet the climb gradient. Anything lower then that you are hosed. I would refer to your 135 companies training program to assist you in this.

I have no idea what you mean by "3.3 climb."

The 3.3 single engine net climb gradient is required for all 135 flights.

ok well you have >5000 so you should already know the answer to this.

3.3 is an ATC climb requirement to participate (sp) in the IFR world.

If you meet the higher value (in terms of the wx) then No 460' pnm. Anything between your numbers (again in terms of the wx) and you need the 460' pnm. Anything less (read not enough wx or too much in your case) and your are out of luck part 135 and/or IFR.

Go VFR (or part 23 doesn't have to do squat but launch and be legal...not smart mind you). You have to meet the 3.3 regardless (part 23 and 25) if'in you are IFR.

So, to review....I think I am not completely hosed so far (it is late)....Go get a beer and wait 8 to 12 hours (FAR or Company) to fly and/or go when you have desent wx.

Peace.

Ok you got me....:blush::smash:


I started looking at some other airport charts and see why that was a pretty stupid question.

Thanks for the help everyone.

Tell him what he won!!!

If you have 3100-3.... You just need 3.3 climb rate to 14000MSL.

If you dont have 3100-3 you need the 460/NM... I think thats over 7.0 climb rate.... I don't know if there are any 2 engine jets that can make that.

Search the Corporate and Charter sections for Aspen.... You will find several good discussions.

 

[ultrarunner]

And don't forget to enter the chart at 14,000'

Nice one . Wonder how many headscratchers are out there right now.

Check out the Apsen Two departure. It requires 5000-5 or 950ft/nm to 12,000'. That's a 15.6 percent climb.

There are 2 twin engine aircraft that I know will make the climb gradient one is the GV light on gas (only like 16000lbs) or enough to go anywhere in the US the other is a global express light on gas (enough to go to Denver)

Hope this helps

What about the C680 and C750?

 

[Jurasic jets]

I am not sure about those 2 I know the 20 series lears won't do it.......

My understanding is that the 3.3 is a standard gross climb gradient under TERPS. However, where ceiling and vis mins or alternative climb gradients are published for a particular departure procedure, they apply--for IFR/IMC operations. The Part 23/25 single engine climb requirements overlap and are actually less than the 3.3, because they do not take IFR/IMC or particular obstacle avoidance into account. Not sure if 135 changes things, but if you have 3100-3, you'll need at least the Part 23/25 climb requirements to 3100 (for a "visual climb" to 3100) and then 3.3 after that. But I think you would need to remain within 3 miles of the airport to 3100 agl. And if you maneuver to do that, consider the effects of your maneuvering on your climb gradient. The net second segment climb gradient under Part 23/25 is something like 1.6%---pretty slim. ( I am interpreting the 460 feet per nm to apply only to the 1000 & 2 wx mins, although it is a bit unclear.)

No way! And don't forget to figure the anti-ice on penalty to the climb gradients.

Approach climb charts can even restrict arrival ops in some aircraft. My MU300 was weight restricted flying *into* Gunnison a few weeks ago because of "Anti-ice ON Approach Climb" requirements.
