First of all, TC isn't going to pull your medical. TC medical is going to send you a letter repeating your ex's claims as if they are facts and telling you to deal with it or face potentially losing your medical. When you take this letter to your CAME, they will be familiar with the process and will...

Further reinforcing the idea that the MP is not what is wearing out the engine, the CHTs are. As long as your CHTs are 380 or below, reducing MP is not going to increase longevity. Depends, what failure modes are you seeing when the engine 'wears out'. The most common wear based problem is excessiv...

See that's what I always thought too but they make a turbo version of the exact same engine that climbs out at 38" every day, so leaving at full throttle at 28" isn't going to make a difference. C-421 has the GTSIO-520. It is in not 'the same engine' as the 185 or such, but the core is essentially ...

It occurs to me that I should give some additional information. During climb I keep the mixture very rich, only leaning enough to keep the EGTs about where they are after takeoff. At all times the CHTs stay below 400. A little hot for a continental but the floatplane is draggy and the 210 doesn't ha...

Full throttle from takeoff to top of descent. Small power reduction after takeoff by reducing the rpm, large power reduction in cruise by reducing rpm and fuel flow.

Hi Bede,

I fly a 180 and a 210 with IO-520s, we do not reduce throttle after takeoff, only RPM. The 210's engine has 2100 hours and 18 years since last overhaul, no issues so far. The 180's engine is new but it flies lots year round so we're planning on getting 3000+ hours out of it.

Jeppesen is stopping paper plates as well. As an IFR instructor, I carry one device with plates, no backup. The student has their own set, I guess that's a backup. The aircraft I normally fly by myself have integrated plates so that's a backup. ATC has plates and I have a radio and a phone so that's...

Constant speed prop. Have very slight movement (noticeable) in mp and rpm. That confirms your oil pressure is fluctuating and it's not a sensor issue. I would ground the aircraft immediately. Do you have an oil filter? I would do an oil change and check the screen and cut open the oil filter. Take ...

Absolutely not. Constant speed prop or fixed pitch? The biggest advantage to the digital engine monitors is that they record everything. These recordings make tracking down problems like these in a scientific manner much easier. Read your manual or get help and download the data. Post it here or pm ...

I had this problem once. Applied ACF 50 (CorrosionX is similar) several times with several hours allowed to soak in, then a final application of Penetrating Oil #1 allowed to soak in for an hour and out came the drain. I've never applied penetrants to a thread that's upside down. Does it work? Oh y...

Sorry, I meant F. Appendix B is fine except that uAvionix will not publish any continuing airworthiness guidance for skipping friction, hysteresis, or scale error so you're wasting time doing tests that should not be required.

Without being very familiar with the TailbeaconX and having been provided a copy of uAvionics software to place the transponder in a ground test mode, many of the tests required by Car 571 Appendix B cannot be performed. As for the ADS-B, there is no requirements for testing in either the uAvionics ...

2021 numbers are not a useful metric. What was the AC CEO’s compensation in 2019?

As photofly has pointed out, none of the equipment needs to be TSO, but then it’s up to you to show that it meets the requirements for IFR when you request the VFR restriction removal. Each time I have had a client questioned by a TC inspector, we were able to get an email from the manufacturer sayi...

30+ years ... if kept inflated. If they are sitting around at 10 pounds most of the time and only inflated at annual, not nearly so long. Even without wear and UV damage most tires don't last more than seven years because of neglect. I would never change a tire by rule of thumb. Change it when it is...

During the biennial check it's 125'. CAR 571 Appendix F.

Lots of homebuilding around Calgary. I'd start here

I think basically the OP wants to move into the Air Force from the Army. There are a couple CF pilots on this board, hopefully they will chime in.

Maybe they don't have enough power to go that fast?

As a minimum you'll want a Garmin GPS175 and a G5 added. That still leaves you with only one radio and an old one at that and you're already over budget.

What's the nav indicator for the KX155?

Which province are you in?

Insurance has been mentioned. You will want to become familiar with CAR 625 Appendices B and C and make sure that the owner has done all the required maintenance. A guy came out here last month to do some training and after a couple flights discovered that the student's plane was out of annual by a ...
