[Nev]

Has anyone read this ? Thoughts ?

I haven't, but since I've become a more visual and less literary guy in modern times, I do love this video series below. I must have watched it a hundred times.

It's more technique than anything and probably doesn't contain the content that's in the book you reference. But I'm a fan.

Yep that a good series for sure !

CC’s book is pretty good, but far from best on mountain flying.

Check out Amy Hoover and Dick Williams’ book, Mountain, Canyon and Backcountry Flying

It is the best in my opinion, and I have read every one I could find.

I am drinking coffee and headed up to scout some goats this morning in my buddies Cub, but if you want a more comprehensive list let me know. Order them all at once and save shipping

[Jhankins]

Utah-Jay I would enjoy a list of other books you know of and think are worth the read

Mountain Flying Bible by Sparky Imeson

[AKKen07]

This was the text book for a college class I took once. Iz gud.

Ok, here are the books I felt had at least some good info. Obviously some are better, several have overlapping info which serves to reinforce it’s importance

And yes CC’s book

Here are some nuggets I got from the books, I carry a laminated copy in my plane.



Take-Off and Landing Calculations




Density Altitude

3% loss of performance per 1000’ DA


Headwind

• A wind of 15mph will decrease Landing Distance by 10%

Tailwind - Add 10% landing roll for every 3mph tailwind ~10mph Maximum~


Gradient Effect on Landing

• Each 1% of slope will effect about 3% of landing distance
• Each 1% of gradient is about equal to 10% change in effective runway length

Unimproved Strips

• Add 20-30% for Long Grass (longer than 4”)
• Add 45% for Sand
• Add 20-75% for Mud or Soft Surface depending upon severity

71% of Vr speed should be reached by the mid-point of the runway


Gross Weight

1% increase in Gross Weight will increase Take-Off about 2%

I have very similar information in my POH...

But all you really need to know is, if the Bearhawk can land there - it can take off again

It's great to have an airplane that can takeoff shorter than land but it's quite easy to get stuck anyways. One time I landed on this strip close to Elba. It was sloped uphill with a power line at the high end. A solid breeze was blowing downhill. This made landing it easy but the uphill departure with obstacle made it very dicy for leaving. I ended up waiting for the wind to turn. Luckily this took only a couple of hours and the locals took me to a nice lunch place where I ate scorpion fish tortellini for the first time. If the wind would not have turned the same day it would have been very handy to run some numbers and then do some mid-point speed tests. Generally I find the mid-point speed check very practical. Use it and variants of it a lot when glider towing on short strips.

I made a Take-off & Landing distance calculator for my iPhone which so far is surprisingly accurate. Its main value is for hot/ high/ tailwinds. For most people it's probably a bit academic (I quickly got used to estimating it) but I still find it useful to get me thinking about these airstrips before launching into and out of them.

I bought CC’s book after hearing him speak on the subject at OSH. His talk was great. I haven’t read the book yet.

I went down a rabbit hole a bit on the subject in YT videos and recall some great information and importance of understanding climb gradient vs climb rate. It is interesting to realize that a ‘high-powered’ airplane like a big engined C-180 may have a lesser ability to gain vertical vs horizontal feet because of ground speed as opposed to a Cub.

Aviation has a lot of "isms" in it. Some modern, some holdovers from 70 years ago. The science and math never changed, but how it was taught and characterized are stuck in various older time periods. Building airplanes has been a continuous process of improvement. Flying them? Two step forward, one step back. Sometimes stuck 5 steps back.
