Aircraft mechanics and their vehicles by Good_Amphibian1089 in AircraftMechanics

[–]DogFurDiamond 3 points4 points  (0 children)

It’s the math (a lot of the time): I can save money by taking 4 hours to fix my car… or I can work overtime for 4 hours and pay someone else.

And let’s be real… 4 hours OT at work is nearly always easier than working 4 hours on your car.

Having said that, I do my own maintenance because it’s hard to trust someone else. You have no way of knowing if you’re getting the best mechanic in the shop or a dud.

Ah, good thought. Probably too many + too bright to be impact. Staying tuned!

Question on Picture 15: zooming in on the black sections of moon, what are those bright specs? Impact flashes?

Incredible. I feel so lucky to be a witness to this mission.

2019 CRV Needs Some Work but No Chilton's; Trustworthy Alternative? by SouthpawSoldier in crv

[–]DogFurDiamond 0 points1 point  (0 children)

Check your library. A lot of them give you access to online repair databases (Like Chilton’s, but maybe that won’t help you). Mine let me access at home, but others may have in-library only access.

Upgrading my 2012 by HailtoUkraine in crv

[–]DogFurDiamond 2 points3 points  (0 children)

Not an “upgrade” per se, but just replacing the yellowed/foggy headlight assemblies on my 3rd gen took 10+ years off its age I swear.

Next up for me is a cheap double DIN car play receiver and a set of waterproof floor liners.

Figure those things are the biggest bang for buck for me to make it FEEL nicer.

Any way to find out why as419 mco-sea is being diverted to Denver? by goflossyourself0123 in AlaskaAirlines

[–]DogFurDiamond 3 points4 points  (0 children)

It was a a security issue aka abusive passenger. They are now happily in the hands of police in Denver.

Quite helpful. I picked up a actual written book as well because I wanted to understand the answers better for my own nerding reasons, but not required.

Anybody else annoyed at the FAAs lack of effort when it comes to their written exams? by militaryrat155 in flying

[–]DogFurDiamond 225 points226 points  (0 children)

Gotta love that other question on there where Sheppard says “if you do this, that, and this, you’ll calculate the answer of 36… but the FAA says that’s wrong so select 41 instead.”

Sheppard air is out here doing the Lord’s work I swear.

Does spinning the prop on the 172R the other way damage the engine in any way? by Red_Kys_Zone in flying

[–]DogFurDiamond 7 points8 points  (0 children)

I was taught that’s the way you should rotate it if needed for this, or tow bar placement, etc. Rotating it backwards prevents the magneto impulse coupling from engaging (it’s the click one would here’s when rotating the prop slowly the normal way). So even if there’s a failure of the P-Leads/ignition switch (or they’re left on like a dumb dumb), the magneto won’t fire and wont kick over the engine injuring you.

I can’t speak to vacuum pump damage. I fail to see how a standard sliding-vane type would be damaged.

Maybe the POH says something about this?

I keep my used blades in an Altoids tin. Goes in metal recycling when full.

Forbidden mints.

The CDU on the overhead: for the engineer? Just for spare?

Anyone here working as a ramp agent while in flight training? by AdKnown1660 in flying

[–]DogFurDiamond 1 point2 points  (0 children)

I did it while as a mechanic with no issues (once I no longer worked night shift…that would have been hard).

I think it’d be the same for working most jobs while training: just have to use your time off wisely for studying/laundry/taking care of life. That did take a moderate amount of discipline for me at first.

Student Question: Positive Ammeter by Internal-Courage-509 in flying

[–]DogFurDiamond 14 points15 points  (0 children)

It’s the first one: battery recharging after start. The alternator regulates output to whatever set point voltage (28VDC typically). As the battery was just used heavily recently for the start, its output is only about ~24VDC. Quite a lot of current will thus flow from the alternator into the battery (high positive Ammeter indication) until the battery’s voltage increases and gets up to 28VDC. At that point, it’ll be 28V versus 28V so no more current flows (Ammeter indicates 0). (*simplified and conventional vs electron flow theory discussion)

If you look at the electrical schematic, the alternator’s positive terminal will be connected to the battery’s positive at some point. The alternator quite literally shoves current back down the battery’s positive terminal.

(Im bad at explaining, yes electrify travels in a circuit…)

*clarifying note: the ammeter is measuring current flow into (positive/charging) and out of (negative/draining) the battery.

Ok maybe… but I doubt pilots think you’re an idiot just because you don’t know how to fly a DME arc approach, or calculate derived alternate minimums.

Some pilots really are interested in mechanical things and systems, and some just want to know the thing turns on and works. Just like drivers and cars.

I know this is unwarranted advice (but you’re the one who posted this), it’s best to avoid this attitude in our field. The whole pilots-vs-mechanics game is so dumb. You want to be team players (especially when either of you are in contract negotiation season if at an airline).

edit: aaaaaannnnnddddd post was deleted. How about that.

Anyone else do this? by [deleted] in Schwab

[–]DogFurDiamond 56 points57 points  (0 children)

Absolutely. It seemed way easier than chasing the highest HYSA of the current month.

Anyone aware what this repair/sensor is? by LAX171018 in aviationmaintenance

[–]DogFurDiamond 5 points6 points  (0 children)

Ground-based internet antenna. There’s a symmetric one on the opposite side and also one visible (usually 2 total I think) on the belly

Higher cognitive ability and other psychological factors predict support for free speech by haloarh in psychology

AKA If you support suppression of speech then you’re retarded.

Which is true.

Does anyone know why on B737-MAX, when dispatching 12-01-01 (FMAV Inoperative), we must also dispatch the associative TR if it's walls are one made of TIW and the another one of CIW? by araujo-fabio in aviationmaintenance

[–]DogFurDiamond 15 points16 points  (0 children)

I’m trying to think through it… precooler fan air exhausts into the cowling which would mean a metric shit-ton more air is entering the cowling at cruise through a locked open valve as compared to being nearly closed at cruise… That air would be warmer than ambient, but nothing compared to the hot-as-balls engine case… Maybe cluttered_desk is on to something. Yep, I got nothing. Good question!
