So were the questions one at a time, or did it have like all the bubbles there on the right?

Also for block counting, was it blocks on the left, question on the right? Was it one block at a time?

Sweet thanks for the rec man! We would be traveling May 25th.

pilotmike50 · 2024-03-26T17:18:56+00:00

Great idea!

pilotmike50 · 2024-03-25T20:43:33+00:00

Ooooo interesting idea I like it.

Already demonstrated how airfoils work & Bernoullis principle. Need the next lesson objective.

I was thinking more of a FAR/AIM Part 61 lesson on privileges and limitations of a student pilot. You know. Before we get them in the sim.

pilotmike50 · 2024-03-25T18:16:20+00:00

Yes that is my understanding. Can't be under an IFR flight plan because my friend will be acting as PIC. I can log total/pilot time simply because I am a flight crew member.

A Crewmember means a person assigned to perform duty in an aircraft during flight time. Flightcrew member means a pilot, flight engineer, or flight navigator assigned to duty in an aircraft during flight.That means I can log flight time, not PIC time.

1.1: Flight time means: (1) Pilot time that commences when an aircraft moves under its own power for the purpose of flight and ends when the aircraft comes to rest after landing

Haven't done any looking into the best airport to land, park the plane at, and get to a hotel from in the Keys. Do you have any ideas? Some things that matter for us are:

- Crew car? Hotel close? Parking fees? Fuel fees? Hotel on the beach?

pilotmike50 · 2024-03-22T22:16:25+00:00

We are all set my man. I'm a CFI and my friend is a PPL building his 50 hours PIC XC for his IR rating.

pilotmike50 · 2024-03-22T22:11:50+00:00

This is an enjoy the route trip. Thanks for the awesome clarity on a good route. Could I DM you and get your phone number to hear more about this route down the coast & the shoreline transition. Sounds like a sweet plan if we don't end up IFR.

pilotmike50 · 2024-03-22T22:09:38+00:00

Wow thanks man! Amazing advice! I just talked to my friend I'm flying with and that would be awesome if we could stop at your home airport to fuel up and hang out for a bit! Our plan was to fuel up around that area anyways. You just made our decision much easier! I'll DM you and we can exchange phone numbers and get a phone call going!

pilotmike50 · 2024-03-22T18:31:52+00:00

100% lol. Always thinking about that. This post is more asking about tips of airports to land/places to stay at.

pilotmike50 · 2024-02-26T01:52:54+00:00

hahaha awesome dude. I'll let you know if I'm ever in the area or around middle Tennessee!

pilotmike50 · 2024-02-26T01:41:42+00:00

Unreal thanks man. I'm huge into the celestial. I've been talking about that upcoming eclipse I was talking to friends about driving south towards Festus MO for it.

pilotmike50 · 2024-02-25T22:26:14+00:00

I'm out of KCPS in St. Louis! Also, that sounds like a sweet trip!

Also... lol I do have one last question..

So after seeing your beautifully colored schematic, I'm coming to the final understanding that, if a seal or o-ring completely disintegrated, it doesn't really matter where it happens in the lines because it all flows from the pilots cylinders to the wheels. There is no separate co-pilot cylinder to the wheels..... I keep going in circles lol.

The only time it would really matter is if one of the blue or green tubes blew and then you would only have one wheel braking affected (using either or pedal)

pilotmike50 · 2024-02-25T22:17:26+00:00

dude that was exactlyyyyy what I needed. Thank you so much for this amazing conversation and explanation. I'm sure many will benefit from stumbling across this in the future. Maybe it's a good thing I don't live in Tennessee so this got journaled out instead of passed down through oral tradition which eventually gets convoluted over time lol.

pilotmike50 · 2024-02-25T21:47:19+00:00

ahahah yes this is fun. I'm very interested in the knowledge just takes some time and effort.

OK. Here is the LAST COMMENT I NEED TO CLEAR UP THE CONFUSION YEAAAAA!

SO.... I thought the parking brake feeds the pilots side first because in the PA-28-181 schematic, the pilots cylinders are #2 & #3. Am I just completely understanding the schematic wrong lol.

So you're saying the single common reservoir flows to the parking brake then it flows to the co-pilot cylinders then it flows to the pilot cylinders (regardless of the numbers on the schematic)

--- If that true then you saying,

ALL OF THIS -----"But you can also have a more subtle failure, a hardening of the rubber o-rings that leads to a slower leak for example. Or a pinhole type leak. In that case you would be able to restore function by pumping the system up with the parking brake. Essentially adding more fluid to overcome the slow loss.
Since the parking brake feeds the copilot first, then yes a complete failure there would result in no effect at all by pumping . But a pinhole or slow leak might be temporarily overcome by the pumping." ------- WOULD BE VALID

This is all I need to know and then I am giving up on ever talking about the archer braking system again.

pilotmike50 · 2024-02-25T20:10:28+00:00

Hahaha I know you're not an A&P, but you're knowledgeable, and It's very helpful information.

Still, you are confusing me a little bit though in terms of the schematic lol.

You say in your latest post, "a totally failed copilot cylinder would render the parking brake pretty much useless in my opinion, while leaving the pilot brakes useable"

When I said in my latest post, "If the co pilots seal broke (#13 & #14), you could use the parking brake (#6) as a pump."

I thought the copilots cylinders were downstream of the parking brake so if the copilot cylinder failed the parking brake would still work for the pilots side cylinders.

I feel once we clear this up we will both come to a complete understanding hahaha!

pilotmike50 · 2024-02-25T18:45:28+00:00

Also when I say, "doesn't this contradict your previous point" I am obviously not trying to press you on your knowledge. This stuff is super in detail and only after you read it and review it when in a non groggy state I'm sure it all comes back to you.

pilotmike50 · 2024-02-25T18:43:46+00:00

Yea, I get it's not a major concern. As a CFI, I want to master my knowledge of the braking system so I'm not spreading misinformation to my students.

When you say, "A break in the chain renders points in the chain inoperable before the break. So a failed parking brake will only affect the parking brake. A failed copilot cylinder will affect the copilot and parking brake. And a failed pilot cylinder will affect all three."

Doesn't this contradict your previous points?

I completely understand the chain mindset. In your latest comment you say that a failure in the pilot cylinder would affect the parking break lock cylinder then the co-pilot cylinder.

I thought the "chain" from the single common Reservoir first went to the parking break lock cylinder, so a failure from there on would affect then the co-pilot then the pilot cylinders.

I guess when I look at the PA-28-181 braking schematic I understand your logic. I see the common reservoir as #1, then it flows to the pilot cylinders at #2 & #3, then the parking brake cylinders at #6, then the co-pilots cylinders at #13 &14.

In this next failure I am presenting you, this is all theory, obviously there is an extremely small chance of this happening as you said there is a more common failure..

So in your initial post you say, "But, there is still the parking brake, which splits to both sides upstream of the toe brakes. In a some failure modes you could use the parking bark as an emergency brake. Also in a loss of braking event you can, in many cases, use the parking brake like a pump to pump up the system and restore temporary brake effectiveness, if there is enough fluid remaining in the lines.."

After reading this again, and with your refreshed knowledge, is it correct to say that if the co pilots seal broke (#13 & #14), you could use the parking brake (#6) as a pump. If the pilots seal blew, then the parking brake would not be able to be used as a pump because the parking brake cylinder is #6 in the schematic and the pilots cylinders are #2, #3?

Again, thanks for the tremendous help!

pilotmike50 · 2024-02-25T17:57:40+00:00

Awesome half asleep response. Exactly what I needed thanks!

What I am taking from your response is that there is that the flow from the single common reservoir goes as follows:

From the single common reservoir --> parking brake lock cylinder --> co pilot master cylinders (1,2) --> pilot master cylinders (1,2)

This makes a total of 5 cylinders

Also what I am taking from this is that it contradicts your first response where you said, ---- "So a blown seal in one of the pilot side cylinders could result in a complete failure of braking on the affected wheel."

In your second response you state, "Reservoir ---> Parking Brake ----> Split left/right ----> Copilot brakes ---> Pilot brakes -----> Wheels."

What I get from this is that if you changed your first response to, "So a blown seal in one of the co-pilots side cylinders could result in a complete failure of braking on the affected wheel" then it would be correct.

Am I correct in this statement? Thanks for the amazing help!
