Re: Short Field Take Off

I raise them at 300' AGL. If I have an EFATO, I want to get to best glide speed as quickly as possible, and glide as far as possible; flaps are not going to help. That's assuming you may be able to glide to a more-distant place to land from only 300 feet. Usually at only 300 feet with an engine fai...

Re: 2200 or 2400 cruise

That’s interesting for me. Because I’m always trying to follow the grid that is in the POH for MP and RPM (I adjust the fuel flow either LOP OR ROP according to Mike Bush advises). But I never use the WOT position when cruising. I religiously follow 26,5/2200 when I’m at 2000ft for tourism and each...

Re: 2200 or 2400 cruise

For 2007 and newer Lycoming DA40s -- all of which have Powerflow exhausts -- the Powerflow exhaust is "tuned" to an RPM of 2450, i.e., it maximizes scavenging of exhaust gasses at this RPM for increased power and efficiency. Obviously you can reduce fuel consumption by flying at a lower RPM where th...

Re: AE330 180hp DA42 STC

Great, so Austros can join the overheating party! Current engines will dip coolant temps into yellow arc on a 40C+ day, especially if engines are warm/second run. I've flown dozens of Austro-engined Diamond aircraft (including my own) and NEVER had a cooling issue. This is one of the huge benefits ...

Re: AE330 180hp DA42 STC

The radiator on the DA62 E4P-C engine is identical to that of the DA42-VI E4-C engine. The only real difference I can see between the 2 engines (I've owned both) is that my 2013 DA42-VI had an air-cooled gearbox (with an attached air duct and external cooling fins), whereas my 2017 DA62 engines have...

Re: AE330 180hp DA42 STC

It would be trivial to load DA62 AE330 (E4C-P) software into DA42-VI AE300 (E4C) engine ECUs to increase maximum turbo boost. But unfortunately it's not straightforward because of the different size propellers (the DA62 prop is 1 inch larger diameter). So ECU control of RPM/blade angle would likely ...

Re: Activating Approach

Simpler answers to the OP (Gary's) questions: 1. Hitting APR key arms vertical (as well as lateral) guidance for capturing a glideslope/glidepath. If you are flying in NAV mode and forget to hit APR when cleared for the approach, the plane will turn laterally to follow an approach you've loaded, but...

Re: G1000NXi with ESP - Missed Approach

The DA42-VI with NXi has Garmin's "ESP". According to AOPA, this means you can fly a fully coupled missed approach. Does anyone have experience with this? What happens if you hit the GA button while the AP is still engaged? The DA40NG with G1000 NXi works the same as Legacy G1000 GFC700: When the p...

Re: Angel City Flyers - IRA KLGB

Does Diamond have standardized training for schools and instructors? Anything similar to Cirrus Approach? In short, no. The Austrian factory has put together a few training presentations that are used only by the Diamond's own flight school (e.g., the Diamond Flight Centre in London, Ontario). But ...

Re: Autopilots are the answer, not the problem...

An autopilot for a DA40 must be built for certified aircraft, although EAA and others have started getting FAA approval for a few non-TSO'ed systems. Unfortunately it means you can't use most of the cheaper autopilots designed for homebuilts in a 2003 DA40.
