Re: Bose aviation headsets...pleased be advised:

If they could not have sourced the parts of the frame I was going to just 3d print them since they are well beyond any expectation of repairs at this point. Exactly. I was so convinced it wouldn't be repairable that I'd already ordered one of these (an astoundingly inexpensive ANR headset) as a sto...

Re: Bose aviation headsets...pleased be advised:

I also own a 15+-year-old Bose X headset. One of the plastic side yokes cracked a few months ago, so it sent it to Brant Aero (the authorised Canadian repair shop) and got it back in a bit over a week, totally overhauled, with stronger side yokes, for just over CA $200 including HST and shipping. I ...

Re: Setting pitch trim for takeoff

Many airplanes have a 1 inch or so “safe zone” and manuals often suggest moving the trim fore or aft depending on your CoG off the W&B. From what I’ve seen, most people seem to leave it in the center anyways. How many of you adjust it or what are your thoughts In my piston single, I always prefer t...

Re: English Vs French on the Radio.

Actually, your claim of well within Ontario is still a highly doubtful one. You still haven't explained how you know where they were since you don't know where they were. Ok A. But over the campbellville VOR, I think was around there -- at maybe 5000 feet, hearing position reports in French, you al...

Re: English Vs French on the Radio.

First, not everyone in Quebec aviation speaks English. I've often arrived at GA airports where the FBO staff has zero English, or close enough as matters. Why should francophone pilots in Quebec subject themselves to extra fatigue and an elevated risk of misunderstanding all the time just because b...

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...

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...

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

If someone's reason for leaning on the ground is for when they forget the basics of the before takeoff checklist, that person has bigger problems to worry about than fouled plugs. ... or it's a genuinely-experienced pilot who's flown enough hours to know that safety comes from multiple layers of sa...

Re: Emergency declared in circuit due to IMC

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...

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...
