Re: Next Rating

So 95% sure next step is instructor rating but just wanted advice/confirmation if you don't mind. Another retired firefighter who has been flying bush planes for quite a while suggested float rating and fly in the bush. If you're considering the float rating and instructor rating, you can pm me abo...

Re: Learning around the clubhouse

This is a fair perspective, but let me offer a counterpoint. If you're chatting around the clubhouse, your conversations are essentially private. This is not true of internet forums. There is an audience, and that audience likely includes people with a genuine desire to learn. This means that trolls...

They tell you , but they can't show you . Sure they can. there is lots of evidence that you can observe yourself to demonstrate the Earth's curvature. There's no need to take anyone's word for it.

Re: Multi-IFR license question

Quick question for the ME pilots of Avcanada: with an an engine failed on a multi-engine aircraft (non-centerline thrust) and the ball centered, are you flying coordinated? No. Why limit yourself to multi-engine airplanes? If you're in *any* airplane, with the ball centred, does that mean you must ...

Re: Books/Websites to help prepare for the TC Written Test?

Can anyone recommend any books, or websites that have sample test questions like the TC Sample test? I found that very useful to highlight areas where I need to review and refresh my knowledge, so I was hoping there are other resources like this out there. Hi Steve. I'm a little biased, but you mig...

Re: Turn Coordinator vs. Turn-and-Bank

Ball just measures the local direction of acceleration - neither slip nor yaw. That's true, but the measure of lateral acceleration is used as a proxy for slip (despite the fact that it's not always accurate). <self-promotion class="shameless"> Read about it here: http://www.flightwriter.com/2012/0...

Re: Single engine Cessna tailplane lift

Were the force which the horizontal tail exerts around the pitch axis to change from a downward force to an upward force ("lifting"), the pilot would experience control reversal, which is extremely disconcerting, and not approvable. It would result in very unpleasing stall handling characteristics,...

Re: Single engine Cessna tailplane lift

There's no pitching moment about the centre of pressure, by definition of the centre of pressure. Since I'm taking moments about the CP, there's no contribution to the total moment from the wing, only from the weight of the aircraft acting at the centre of gravity, the pitching moment of the fusela...

Re: Effect of altitude on Fuel Burn

At a (sensible) fixed Indicated airspeed your MPG figure gets worse as altitude goes up, but you'll get there faster. That depends on what you mean by "sensible". Best range occurs at a fixed AOA, and therefore a fixed CAS. So ignoring the effect of the climb, your best range doesn't change with al...

Re: Powered vs. Power at idle landings.

Not to mention landing from a curving approach is oh so much easier. It's not that difficult and is amenable to training. In any case, it doesn't need to be oh so easy. It needs to be something a low time student pilot can learn and retain -- so that 2 years after getting a license and flying once ...
