    Switching Options of Essential Equipment

    I have lost switches before. But switch failures are much more predictable. I have ~750 hours. I do not think I can recall all the electrical failures I have had. Always in a plane with redundant systems. Off the top of my head: 1. PFD Failure, blank screen (Avidyne) 2. MFD Failure, blank...

    Switching Options of Essential Equipment

    @wsimpso1 I have started to read aeroelectric. It will take me a long while. Here is a question though, since you seem to want to be able to selectively bring up systems. A friend had 45ft yacht, out fitted for running the ocean. He said, when planning for ocean running, you have to have...

    Switching Options of Essential Equipment

    I like the Cirrus electrical layout for the most part. Two busses, essential and main. Backup alternator and backup battery connected to essential. Main battery connected to main buss along with the primary alternator. The main bus runs at 28v, the essential bus is tuned to 26v. Both batteries...

    Electric Aircraft Manufacturer Electron Secures Orders from Air2E, Hopscotch

    Well I contacted GoFundMe, to discuss a satire or phony company raise that does not allow people to actually invest. The CSR liked the idea, and was planning to send it off to the management team. Basic idea was to build a profile out, after someone clicks invest/donate; have a second page which...

    I wonder if we could actually post this on a gofundme page? :D Tim

    Electric Aircraft Manufacturer Electron Secures Orders from Air2E, Hopscotch

    Um, are you positive on the absolute factor here? I think it was Toyota's new battery tech that the rate of charge affecting battery degradation was almost completely related to temp. And there were other battery announcements along the same lines; that higher temps while charging are the...

    I wonder if in the artist renderings include basic weight, structure, and energy density requirements.

    Pushers...way to go ?

    The Cirrus experimental CK-30 I believe was the name, has had multiple crashes due to the drive shaft extension. Tim

    Swift Fuel Unleaded Causing Valve Problems? UND goes back to 100LL

    Ok, consider me confused. 94UL is just 100LL without the TEL. Correct? And the aromatics mentioned Lycoming's answer are the same ones GAMI is using as the core foundation to make G100UL. So, how does this make sense? Tim

    Blended wing ACs are coming !

    Curious, why so many on here do their own perceived virtue signaling about spending any money on things they disagree with? Can we avoid it? Trying to stay on topic, as displayed, I think the JetZero has many problems, most of which have been listed. Such as Jet Bridges and terminals. There are...

    Sun ‘n Fun 2024: Piper To Test DeltaHawk Diesels In Seminoles

    If the deal was structured in some way as to make everyone who ever invested in DeltaHawk "whole" again, I think your number is very low. If the deal was structured (as I would likely believe) for the Rudd family to get a positive return, I think your number is fairly high. But this is all...

    Sun ‘n Fun 2024: Piper To Test DeltaHawk Diesels In Seminoles

    Hundreds of millions is what has been stated online and in a few articles over the years. From what I have recall, the Rudd family purchased DeltaHawk a few years ago. What I have not seen published, since this was a private deal is how much was the purchase price and how much has the Rudd...

    Sun ‘n Fun 2024: Piper To Test DeltaHawk Diesels In Seminoles

    G100UL is looking to add at least a $1 to the price of avgas. With the recent price increases for CMI and Lycoming for 160-230HP engines, the potential savings might be there. It will depend on both the cost to pursue the STC and the cost to implement the changes. Since we are on HBA, I am...

    Today's Sketch

    That might be fine for ailerons, rudder or elevator/stabilizer, but not flaps. Based on @addaon previous comments he wants identical solutions for all seven control points. Not knowing any better, I would think it might be easier to have two types of control surfaces. One which centers on...

    Blended wing ACs are coming !

    Outside of three classes in college, I stopped taking advanced math classes 38 years ago, and those college classes were about 35 years ago! So I thought it might be fun to try and figure out the acceleration rate. I found this: https://todocalculator.com/roll-acceleration-calculator/ and gave...

    Blended wing ACs are coming !

    @Tiger Tim Two thoughts on this. 1. The pace of change has dramaticlly declined over the decades. Likely because the easy ones have been done already, and I am guessing here, that computer aided designs have made it much easier to get closer to optimal with many fewer steps. 2. Significant...

    Blended wing ACs are coming !

    One of the marketing packages from some company pursuing it addresses these issues. First, no physical windows, they have high resolution "windows" and "sky lights". Second, the baggage/fuel areas instead of being below passengers will actually be on the sides, hence why no side windows. This...

    Today's Sketch

    @addaon One of the feedback items in some crash reports on Airbus, is they joystick gives no feedback to the control surfaces. Are you planning on any feedback from the control surfaces, or just one way communication? Tim
