    Restricted areas times and altitudes

    Hi Guys, Covid has prevented me from visiting the USA for two years now and I was doing some flight planning to refresh my brain. It occurred to me that my preferred flight planning App doesn't have any way to lookup the active times or altitudes for restricted areas. Google was spectacularly...

    2nd class medical

    Hi guys, I have a question for you :) I have an FAA Pilot Certificate supported by an FAA class 3 medical. This has been a valid combination in the UK for the 30 years I have been flying. However, the CAA has just decided that the rules state that a class 2 medical is required. I tried...

    Superior Airparts 100HP diesel engine

    This just in... Superior Launches 100 hp Diesel Engine | Flying Magazine Superior introduces diesel - AOPA I notice a fairly big discrepancy in the predicted fuel consumption. Reports vary from 20 or 25% "better than an equivalent...". But the flymag report says 4.5gph! That isn't "better"...

    Renter insurance

    Hi Guys, (Have I found the right section to post this? Feel free to move it if not) For those that don't know me, I am a Brit with an FAA Pilot Certificate. With the cost of flying so expensive in the UK, most of my flying is done on my annual trip to Florida. This year I was asked to prove...

    FAA PPL in Europe

    Hi, I have an FAA PPL but live in the UK. At present, I can fly G registered planes in the UK (with some restrictions) without having to convert to a CAA/JAA/EASA licence. However, it looks like EASA may not permit this arrangement to continue. My questions is: What would be my least-cost...

    New Rotax engine 912iS

    I see Rotax now offer a fuel injected version of their 912. Same 100HP, but 38-70% more fuel efficient. I wonder if that is a response to ULPower stealing market share. I also wonder which engines it is "more efficient" than. If it is their own 912S, then I'm quite impressed. I'd like to...

    Optimum propellor speed

    Wotcher, Ok, LyCo's typically spin the propellor at 2700, Jabiru's 3300. I also understand that (generally) the faster you spin the propellor, the more noise it makes. And (I think) the less efficient it becomes. Modern engines want to spin faster than that, introducing the need for...

    Total 91UL fuel

    I notice that Total have started shipping a 91UL Avgas in Europe. Starting with France and Switzerland, the UK launch is in September. This is an avgas, not a mogas, and is basically 100LL with the lead taken out. Apparently EASA has given blanket approval for any engine where the...

    Cafe - Pipistrel G4

    Hi all, I've just seen a picture of the Pipistrel entry. Can anyone explain to me why two fuselages and a third pod between the two for the engine is a good idea? I admit, I am only a spectator when it comes to aircraft design, but it instinctively feels wrong. In fact, I would hate to be...

    New engines from ULPower

    According to this month's Flyer magazine (June 2011), ULPower announced new engines from 145 - 200Hp at Aero Friedrichshafen last week. With 100LL being withdrawn, this looks like a good move, giving them engine choices between 100 - 200HP. However, I can't any details, or even confirmation...
