You'll hear the RV guys call in as "RV 123 Romeo Victor", but that's because the RVs have become so ubiquitous that the controllers all know the type of aircraft, so that tells them a lot about speed and performance to help fit them into traffic flow. Unfortunately, KRs are so rare that most controllers have no idea what they are, so calling in as "KR 1213 Whiskey" doesn't help them. I always use "Experimental 1213 Whiskey" for the KR. They usually refer to me as either a GlassAir or an RV. When they ask aircraft type, most aren't familiar with the KRs.
For my home built SuperCub, I always use "SuperCub 143 Whiskey" as that tells the controllers everything they need to know about my performance in traffic; s...l...o...w. I tried using "Experimental SuperCub", but the controllers invariably shortened it to "SuperCub". Being experimental doesn't really pertain to the performance, so doesn't tell ATC anything they care to know. -Jeff Scott Los Alamos,NM > Sent: Thursday, June 26, 2014 at 7:50 AM > From: "Rayner, Todd M. via KRnet" <krnet at list.krnet.org> > > Maybe a silly question but what do you use as a type designator when calling > ATC in your KR2?
