Re: IFR work

What might surprise the OP coming back to civilian IFR after a spell away in the service is just how much GA IFR has changed, even just in the past 5 years. For example, NavCan has torn up most of the Victor and Romeo airways in southern Ontario and Quebec and replaced them with twisty GPS-based T-r...

Re: Navcanada discontinuing approaches at under-serviced airports

According to an airport manager I talked to, Nav Canada now pays for maintaining approaches only at airports with some kind of scheduled airline service (there might be other exceptions). For example, Gatineau CYND has a few weekly scheduled flights to Quebec on Air Liason King Airs, so they still g...

Re: How far do you lean while on the ground before takeoff

Exactly. I have no idea what effect using a brutally lean mixture setting on the ground is having on my CHTs because they are climbing rapidly anyway. Photofly the aircraft is a BD4. Same engine and about 1/3 the frontal cooling air intake area as a 172. Very good temps full power climb and cruise ...

Re: How far do you lean while on the ground before takeoff

65% is 320-360. I don't think 75% is much higher. On the ground, do you find that leaning has much of an impact on the idling temperature? In theory, the lowest CHTs should be when the mixture is extremely lean (just above cut-off); the next lowest should be full rich, and the hottest CHTs should b...

I have a normally aspirated engine. If it's 25°C outside it will hit 400°F in under 10 minutes at idle.
What do you see at 75% cruise?

Re: How far do you lean while on the ground before takeoff

I always preferred to have a cooler cylinder head temp on takeoff. The last thing I'd want to worry about on takeoff is an engine that is at its thermal limit (considering age of engine, students beating it up, etc.), and that thermal stress is even more pronounced at colder temperatures where shoc...

Glad to see that the comments have been supportive. I trained at that same airport in 2002, and know the circuit well. Aside from the pilot's concern about his own safety, I agree that a pilot, within a mile of one of Canada's busier airports, who finds himself suddenly in a situation where he isn't...

Re: Aim to be a zero - Chris Hadfield

I think the point is that if you aim to be a zero, you have a good chance of ending up as a +1. If you aim to be a +1, you'll probably end up as a -1, because of all the people you end up elbowing and climbing over trying to get there. In coding, we have a similar motto: always underpromise and over...

Re: ADS-B Weather vs XM Weather Canada

I am having troubles finding ADS-B weather coverage information for Canada. US FIS-B radar does extend a bit over the border into Canada—at 6,000 ft over Pembroke, or 5,000 ft over Ottawa, I can generally pick it up on my GTX 345 transponder and get radar coverage ~50–100 miles into Canada (give or...

Re: Circuits and Phraseology at Uncontrolled Airports

At a uncontrolled aerodrome, each pilot can determine the appropriate runway for him or herself, can they not? That's more-or-less correct, but if something went wrong, you'd have to work a bit harder to demonstrate that you were meeting that fuzzy requirement to "exercise good airmanship" if you w...

It’s about predicting your own performance and matching your flying to your prediction, and not about aceing the shortest touchdown over the obstacle in history.

The Garmin GTX 345 uses 1090 MHz out (which will work in Canada as well as the US), and supports both 1090 MHz and 978 MHz UAT in, so that you can get all the goodies in the US.
