Summary

Max talks with Dr. Catherine Cavagnaro about the dangers of "timid turns" in traffic patterns, where overly shallow bank angles can lead to overshoots and potentially dangerous skidding turns. Catherine recounts a case where a pilot overshot final approach due to excessive speed and timid turns, underscoring how these habits can increase the risk of stall-spin accidents.

They explore the physics of turns, emphasizing that speed impacts turn radius far more than bank angle. A 30-degree bank is both safe and effective, increasing stall speed by only 7% while significantly reducing turn radius compared to a 20-degree bank. Dr. Cavagnaro criticizes overcautious instruction by some CFIs, which perpetuates unsafe patterns.

The conversation also addresses circling approaches, where incorrect visual references at lower altitudes often cause overshoots. Both Max and Catherine cite fatal accidents caused by such errors and stress the importance of proper airspeed, situational awareness, and wind evaluation.

They recommend practical techniques, such as using GPS and visual landmarks, to maintain safe distances and precise turns. Dr. Cavagnaro encourages pilots to embrace effective strategies for tighter, safer traffic patterns, and avoid the pitfalls of timid turns.

0:00.0	At some time in your flight training, someone may have told you to keep your turns in the traffic
0:06.4	pattern relatively shallow since stall speed increases with bank angle, and of course you'd
0:12.4	never want to stall an aircraft in the traffic pattern.
0:15.4	But as Dr. Catherine Kavignaro explains to us today, by doing that, you may actually be increasing your risk of
0:22.0	stalling in the traffic pattern, and she'll explain why. Also in this episode, we have a great
0:27.3	new video of the week, and we'll talk about how Apple's iPhone crash detection works to notify
0:33.3	authorities if you crash a plane, and we'll talk about another plane crash in which that occurred.
0:39.1	Also, DPE Jim Pittman talks about what you need to know about foot position. And I'll tell you
0:44.4	about my vision jet trip that I took earlier today and about something that happened to be
0:49.0	on the guard frequency, which has never happened before. And if you'd like to get a new headset
0:53.2	sometime with the coming months,
0:55.0	you may want to jump on a discount that Lightspeed is offering during the holiday season
0:59.2	that will save you money.
1:01.0	You can get $100 off a brand new Lightspeed Zulu 3 headset,
1:04.5	which brings the price down to $7.99.
1:07.0	Now, that's a great price for a full-featured noise-canceling headset,
1:10.6	the same headset that I use.
1:12.4	And that deal expires January 13th.
1:15.0	So take advantage of it now before you get busy and forget to do it.
1:18.9	To get that deal, go to AviationNewstalk.com slash lightspeed.
1:23.1	Let's get started.
1:24.2	Hello again, and welcome to Aviation News Talk, where we talk in general aviation.
