Max Climb & Turn

[designrs]

I had an aborted landing today that was somewhat challenging. Lots of turbulence on final. Decision made to abort landing from about 300 feet up. It needed a rapid climb and 90+ degree turn to avoid terrain. Very non-traditional. There was a mountain at the other end of the runway. It was not a stay in the pattern type of thing. It was more like, get out of there!

My best angle of climb is 60 kts. So if I climb at 60 kts while executing a 30 degree bank turn with the ball centered am I safe in avoiding a stall?

Yes. It was intended to be a landing on a paved runway, but the airport was small, there was Class-C airspace above it. Mountains on the opposite end of the runway. Located in a valley that picked up winds, combined with kind of a mountain pass where the winds blew through. Lots of stuff going on. It was a low wind day but still getting tossed around on final. Too many issues.

A 30 degree turn will increase your stall speed by 7% (45 degrees is 19% and 60 is 41%). This comes to around 3 kts for an LSA so you were fine. 45 degrees could be a bit more problematic.

As long as the ball is centered you are coordinated you won't stall.

No, that's not right. As long as the ball is centered, you are coordinated; you won't spin. Certainly you can stall. You stall every time you land properly (hopefully, with the ball centered). And you practice stalls all the time, with the ball centered!

This is a dangerous bit of misinformation. Is it what you really meant to say?

How many hours of flying time do you have? Are you licensed?

I'm really starting to think someone needs a 709 ride.

This thread raises a question. We all learned that stall speeds increase with bank angle, but are other speeds affected? Do Vx or Vy increase?

[drseti]

I think not, Bruce. Vx and Vy are both related to lift-to-drag ratio. In a bank, neither changes (although the direction of lift is still perpendicular to the wing, thus no longer vertical).

In my short 66+ years, I have never before come across someone who knows so little and claims to know so much.

Priceless.

SportPilot hit the nail on the head. Stall speed goes up based on load factor rather than just bank angle. Load factor only parallels bank angle in a steady state turn. Climbing and turning could increase the stall speed more than turning itself.

It boggles the mind.
