    Remembering Dale Carlson

    Wow, a sobering moment that I'd like to share. I haven't logged in as Sierra Bravo for a long, long time but I just did when I clicked on the wrong screen name. I was surprised to see several PMs in...

    Here's an interesting quote from the president of ACK.

    I'm betting lots of folks around the Kenai Peninsula fire were happy to have drones assisting. Whatever it takes.

    Take what you want from this story but two items of interest are

    1) a flipped/partially submerged airplane
    2) SAR flew to the coordinates of the ELT beacon

    406. Get one.

    Frenchy,

    My mechanic always wanted the prop pitched to see 2400+ at static. For me that equated to 2600+ in cruise. Your cruise example seems a little low. In my experience with a coup[le of bad...

    Compression tests have the piston at TDC. Cylinder glazing happens below that. Too low cylinder pressures are always a break-in concern and flat pitched/STOL props can be contributors. Run it hard.

    I figured as much re: the blending of information. The problem is that one bad set of info will contaminate the entire report. Probably a low risk but I'd still use a dipstick and have a good idea of...

    It's an attractive instrument and I've looked at it a little. Compared to my current digital fuel quantity instrument I thought the CGR-30 fuel mapping procedure was goofy. Mapping? Starting with...

    Macbook Pros have CD drives? ;-) Seriously, my newer Macbooks don't have CD drives. I'm surprised you guys aren't copying your disc content onto an external drive.
  10. Mike, I believe you're misinterpreting the...

    Mike,

    I believe you're misinterpreting the other thread. The GPS receiver in that unit is internal and does not require an external antenna. The ELT transmitter does use a BNC connector to a cable...

    The ELT is not dependent on aircraft power. I believe Darrell is addressing the potential for an external GPS to be powered off. In that case the last GPS position would stay in the ELT memory and...

    Welcome. I'd appreciate some discussion about the reliability of your internal GPS. Does it work equally well whether in a Cub, a Lancair, or under the cargo floor of a DC-3? Are there any...

    Remember, radios are not required equipment in the vast majority of airspace. Don't forget to look outside with that in mind. Especially as all the summer hobby flyers cruise up and down over streams...

    Pundy,

    The hard part of any ELT installation is the structural requirement. Max deflection of the installed ELT can't exceed 1/10th of an inch with 100# of applied force in the most flexible...

    Whether a 406 beacon remains viable and active or a GPS enabled 406 sent a couple of transmissions out prior to being destroyed, a 406 beacon action is not a search. It's a rescue and recovery. You...

    Fobjob,

    For a redundant 121.5 beacon to be theoretically effective the ELT must continue pinging while searchers are arriving into the area. Think about that. For a 406 ELT to trigger a search...

    Every 406 ELT that I've seen has a self-test that's required to be done periodically from the remote panel switch. Artex recommends once a month. ACK once every three months. Do what your manual says...

    Everyone interested in this topic should arrange a visit to the RCC or your regional equivalent to see for yourselves how these devices work in real life. Please take the time to do so.

    Last I looked there was no regulatory requirement in the ELT TSO for GPS and more to the point there is no TSO standard for optional GPS accuracy or reliability. As long as the ELT operates to ELT...

    Any 406 ELT is better than any 121.5 ELT. All the 406 ELTs conform to the same TSO and share the same structural installation requirements. That being equal there's no statistical advantage of one...

    An old post that reports actual sound levels from a noise meter. Decide for yourself whether hearing protection is important. Flying for my kid was like riding in a car. It's how we traveled. DC...

    With either my iPhone or iPad the GPS accuracy on Foreflight is usually reported as 5 meters or occasionally is 10 meters. I can't recall it being worse than that for longer than a moment or two....

    My first generation iPad needed help so I added a Glo. It works great. My newer iPad mini 4G doesn't need any outside help. It acquires a GPS lock anywhere I've tried. Cell service has nothing to do...
