AZAV8OR Posted July 11, 2014 Report Posted July 11, 2014 I am just short of moving into the FD world from the Cirrus world. I've been looking for information regarding the minumum safe altitude at which BRS becomes viable, but the POH is silent on that datapoint. With my Cirrus, I have a 500AGL "Flaps and CAPS" callout: flaps up, chute viable. What's the common wisdom for a min altitude SAFE BRS deployment? Thanks!
FlyingMonkey Posted July 11, 2014 Report Posted July 11, 2014 I'd pull it at any altitude if I needed it, it can only slow you down...
AZAV8OR Posted July 12, 2014 Author Report Posted July 12, 2014 Thanks, guys. Are the altitude parameters in some document aside from the POH?
Jim Meade Posted July 13, 2014 Report Posted July 13, 2014 From the BRS FAQ: "Q. How low can the parachute work? A. The altitude required is a function of speed more than height. FAA certified tests have shown that full parachute inflation could occur as low as 260-290 feet above the ground."
Jim Meade Posted July 13, 2014 Report Posted July 13, 2014 "What's the common wisdom for a min altitude SAFE BRS deployment?" One of the best ways to have the best answer for a question is to redefine the question to fit the answer one prefers. Minimum safe altitude is not talking about "something is better than nothing". It's talking about an expected outcome that corresponds to what BRS advertises. If you want to base your decision on what the company says, then Roger is probably right that you should contact the company directly. Second hand accounts will not satisfy your curiosity as well as your personal, direct contact. I didn't see anything on the BRS website that answered the question any better than the FAQ I quoted. If you find something in writing that can be cited, I'd appreciate it if you'd post it. I'll be in OSH this year and will be sure to ask your question and see if I can get a published reference when I visit the BRS booth.
Ed Cesnalis Posted July 13, 2014 Report Posted July 13, 2014 To pull or not to pull is a question, but embedded in the standard emergency sequence of GGG... G = glide, set for best glide first (then put in 121.5 and 777, then do a mayday call) G = grass, look for a spot to do an emergency landing or set down (or decide to pull: shut off ignition, fuel and open doors) G = gas, if you decided to land you may have time to try to restart the engine. If the chute is out, don't bother. If you are stalling on base to final, none of this matters anyway. None of the above applies. If I loose my engine the first thing I will do is trim fro best glide. Talking and squawking can wait, I'm going to fly the plane and decide on a landing approach next. What good is best glide speed if its not on a heading that will get you to a field?

Ed Cesnalis Posted July 14, 2014 Report Posted July 14, 2014 What does adding dedicated grounds to various systems over time result in? Sounds a little like adding problems to solve problems.

He'll be based out of Chandler, AZ Welcome aboard, Kevin I just posted the adoption annoucement in my "Wanted to Buy" posting. To all that have responded to my posts: thank you for the warm welcome!
AZAV8OR Posted July 15, 2014 Author Report Posted July 15, 2014 Hello 100Hamburger , How does the 796 come out? I've not seen my airplane yet, but I assumed I'd have to remove the metal panel it's mounted in to get to the back. Thanks!

I've not seen my airplane yet, but I assumed I'd have to remove the metal panel it's mounted in to get to the back. Thanks! There is a 3mm hex midway up on the right side of the installation. Just turn it clockwise a quarter turn and pull out the right side first. The antenna connection is located on the upper left side and requires minimum effort to rotate out. Reverse procedure to reinstall.
