Aspen Avionics Enstrom 480 Helicopter Flight Testing STC Supplemental Type Certificate. Did I get your attention with that one? That sound just never gets old. No matter how times you start a turbine helicopter, that never gets old. Hello. I'm Kenny Keller, the creator of Helicopter Online Ground School and author of the Amazon Bestseller, Helicopter Check-Ride. I want to share with you some footage of a flight I got to do -- well, numerous flights I should say -- for the Avionics STC in the Enstrom 480 Helicopter for the Aspen Avionics EFD1000H System. I wanted to share the footage and share the story just because it was a really neat deal. I was glad that I got the opportunity to do this flying. We had numerous flights doing the actual flight testing, going through the parameters of all the things that the FAA set forth that they wanted us to do. And then, after going through a long list of things that they wanted us to do during the testing, they sent out one of their representatives from Texas to fly with us, and we went out and basically did -- the majority of what we did during the testing, we went out and did with someone from the FAA. So, it was just really neat to get to see firsthand how they go about doing an STC, a Supplemental Type Certificate. So, the biggest thing I learned was, you know, we all get kind of comfortable in flying in our normal place, like at home around the airport, or whether you're doing training, or whether you're flying oil rigs, or whatever you're doing. Most of us, we know pretty well what we can do performance wise and we're not necessarily every single day doing a lot of different performance planning. But, when you go to an airport and go to fly at a place you've never flown before in an aircraft you've never flown before, you know, you really kind of have to get back to basics and say, "Hey, I really got to do a good preflight," as we should always do a good preflight. But, a new aircraft, you take even more time than what you normally would. It's a proven fact that the more we fly most pilots start getting a little lax the more comfortable they get with an aircraft. So, do a really good preflight with this aircraft and sit down and go through the performance planning. I remember driving up the one day. We were going to go up to 13,000 feet for the testing, and I'm talking to the checker, a buddy of mine on the phone, and he's like "Hey, don't forget to check the POH to see what your VNE is at 13,000." And I'm like, "Yeah. I better do that." What I was surprised to find, I had never been up to 13,000 feet, that the VNE at 13,000 on that day was like 47 knots or something crazy. So, it's really amazing. When you get out in the real world and, you know, you're planning on getting into a different place, a different environment, a different aircraft, you start doing the planning, sometimes you'll kind of surprise yourself. And we were doing all kinds of things. Sidewards flight, rearwards flight, hovering, taking off, turning 30 degrees to the left, banking back to the right 60 degrees, holding it for so many seconds, banking back to the left 30 degrees, and then going back to neutral. And the list kind of went on and on and we thought it seemed like a little bit of overkill. But, you know, in the end, they're making sure that this piece of equipment is going to work through all the different parameters and all the different flight situations. If you'd like to go to our website to learn more about our Helicopter Online Ground School, there's a link below this video. There's also a link for my Amazon author page, So, hopefully, that gives you a little bit of insight into all the work that goes behind a Supplemental Type Certificate. This is why they don't want you to just build your own spray boom, and build it, and throw it on your helicopter, and go out and start flying with it. There's a lot of testing that goes on behind the scenes to make sure that whatever piece of equipment you're adding, you know, fits the environment, and works properly, and it's going to fit well with the aircraft. So, I think the most interesting thing was the last flight we did before going up with the FAA was we went up every 1,000 feet, flew at 1,000 feet for five minutes, recorded temperatures. You can see they have wires hooked all over the place and we're documenting everything that we're doing. And going up to 13,000 feet was pretty cool. I'll admit it. I'd never been to 13,000 feet before in a helicopter.
