    Density altitude and runway length quick guide?

    I always carry the documents folder in my bag and it has a page with the DA chart (_not_ the Koch chart). It's a quick check. Unfortunately, I don't know where the authoritative source of the chart is. The FAA-H-8083-25A has a version of in the relevant section, but it's a little too small. Do...

    European GPS is down

    They have a mandatory ADS-B, which cannot work without a satellite navigation system. Basically everyone uses the normal, American GPS. But I don't think they have monitoring stations that can provide data for WAAS.

    European GPS is down

    Fortunately, American GPS still works. Yeah, I know that "European GPS" is not correct, because their satellite navigation system has its own name, which is not a "GPS". Anyway, just imagine if GPS went down for a week, with no resolution in sight. People would be brushing up on those NDB...

    American pulsejet aircraft

    Tangentially, Russians still use similar drones, with some differences. The biggest is, their drones are smaller (ba-dumpsh), intended to imitate gliding bombs and the like. Also, they use valve-less pulse engines. There were some advancements since V-1, you see. Here's the manufacturer's...

    Ercoupe or other ideas?

    One of the most commonly adopted LSAs is Sky Arrow. Something in the design makes it very easy to use a T handle for rudder control. Also, it's relatively less impossible for the front pilot there to get in and out of wheelchair (although I imagine someone needs to wheel the chair into position...

    How do you forget to lower the gear?

    Journalists were doing their journalist thing as usual. The final report contained no such nonsense. https://app.ntsb.gov/pdfgenerator/ReportGeneratorFile.ashx?EventID=20160519X25723&AKey=1&RType=HTML&IType=FA

    How do you forget to lower the gear?

    Amazing, I thought only Russians were capable of that, as in 2001 Aeroflot 521 landing in Dubai (all 322 passengers of the widebody Ilyushin-86 survived the gear-up landing, according to newspapers at the time).

    If You Can’t Fly in The Air Force...

    Still, started flying in 2016 and it is 2019 now. Getting into Mirage F1 in less than 3 years, that's pretty good. It's frankly amazing the he managed to stay airborne long enough for Hifter's people shoot him down. In fact he landed that Mirage several times prior. No word as to if he actually...

    Liquid Cooled Aircraft Engine

    Just as a point of comparison, Lycoming DEL-120 is used in large, MALE-class drones, of which U.S. ordered 19 in 2017. So, let's say 30 engines in a couple of years, just to be generous. Meanwhile Rotax cranked out 50,000 912 engines over 25 years, which comes to about 2000 engines per year...

    Liquid Cooled Aircraft Engine

    Yeah, well... Lyc made noises about FAA certification of DEL-120, but apparently nothing came out of it. It was 3 years since they mentioned it last time. Instead they just crank them out for drones (seen a video with Paul Bertorelli visiting the factory). The refuse to sell those engines on...

    Liquid Cooled Aircraft Engine

    Aren't you forgetting about Rotax 912 family?

    How do you forget to lower the gear?

    Maybe it's time to attend some local fly-in breakfasts? The main reason is, forgetting flaps usually does not cause an accident. In most light singles, the distance between the bottoms of the green and white arcs is not great enough for this mistake to manifest. I done it in the M20E, BTW. Went...

    Anybody know if Garmin pilot has this feature?

    My first airplane cruised at 68 knots. I assure you those numbers didn't appear on the compass any time there was a crosswind.

    Anybody know if Garmin pilot has this feature?

    I turn the tablet off when I have the field in sight and pull the prop to high RPMs. That said, I saw the extended centerline on some of the panel navigators. IIRC Aspen does that.
