    Low oil temperature on 915iS.

    In my opinion it is best to consult the engine manufacture for the optimum oil temperature range. It has a lot to do with where the oil temperature sender is located. Some engines may have fifty degrees higher oil temperatures elsewhere in the engine.

    Fatal - N419LB Oklaholma

    I feel the takeoff decision was likely made before the takeoff was commenced. Uphill with a tail wind and a fence in three hundred feet reads like poor aviation decision making to me rather than a medical issue.

    Fatal - N419LB Oklaholma

    In my experience it is not unusual for someone to imagine that a gyroplane is a short takeoff and landing aircraft. In my experience it is not unusual for someone to imagine that wind direction is not an important part of the takeoff decision. I have made some poor aviation decisions myself...

    Fatal - N419LB Oklaholma

    I have no information on the photo. When I saw her she was in the ultralight area of AirVenture with a cover over her. This is not my picture either.

    Fatal - N419LB Oklaholma

    I had a vague recollection of seeing this Cavalon at AirVenture so I checked facebook and there is was.

    Low oil temperature on 915iS.

    I have not had a problem like that with a Rotax 9 series engine. When I get the foam in the oil of my Lycoming IO-320 I suspect it is because of water contamination in my oil. When the water in the oil boils it makes white/yellowish foamy goo. It usually happens when I allow the oil to get...

    Low G and Rrpm decay rate

    I can tell when my clients become comfortable flying as their control inputs become smooth and progressive. Perhaps I am confused because I was not taught the jab technique. With all of the gyroplanes I have flown smooth control inputs worked best for me. Smooth control inputs seemed even...

    Low G and Rrpm decay rate

    I find clients often stab at the cyclic when they encounter rough air. One of my demonstrations to show them the futility of this is to take the controls and move the cyclic rapidly in a four inch circle. It appears to me there is no effect other than the rotor slowing down a little. I...

    Some thoughts on cross wind takeoffs.

    That is the compromise exactly Christine. I find it is difficult to teach people the effect of left or right disk angle on the takeoff roll particularly with linked nose wheels because the pedals control the direction. The surprise comes when they lift off and they have to correct the disk...

    Low G and Rrpm decay rate

    In my opinion based on my gyroplane flying experience a quick jab of the cyclic won't initiate anything. In my opinion if he had three hundred pounds of thrust a foot above the center of gravity there are three hundred foot pounds of torque trying to rotate the aircraft around its center of...

    Low G and Rrpm decay rate

    I feel there are not more videos of the accidents that Doug is describing because there is not much reason to video a flight of someone just flying the pattern. An airshow demonstration is more likely to have a video of it. It appears to me the video shows a bunt over at the top of a zoom...

    How to get your basic Medical

    This is what shows up on the FAA website now: Medical Information: Medical Class: Third Medical Date: 11/2019 MUST WEAR CORRECTIVE LENSES. BasicMed Course Date: 10/20/2021 BasicMed CMEC Date: 10/13/2021 It really was that easy. At the bottom of the form from AOPA is a thing that can be...

    Low G and Rrpm decay rate

    Yes, if I have her nose up at full power I may see the rotor rpm decay from three hundred thirty rotor rpm to perhaps three hundred depending on conditions. I have seen more on occasion. I feel anything over two hundred seventy RPM is acceptable for my rotors on The Predator based on...

    Low G and Rrpm decay rate

    I don’t know what a “power hover” with a gyroplane is. The gyroplane I fly will descend at around 20kts indicated air speed at wide open throttle. If I have the nose up in order to minimize the descent at zero indicated air speed and wide open throttle the rotor rpm will decay. In a power off...

    Some thoughts on cross wind takeoffs.

    I feel there is value in re-examining my takeoff procedures flying The Predator from time to time. Whatever gyroplane you fly; please follow the procedures in the pilot’s operating handbook. I had a particularly challenging client who asked a lot of good questions about the how and why of the...
