While, I've always listened to the Art of Manliness podcast while running, I've recently started to listen to more podcasts.

A screen fine enough to adequately protect from birds, would most certainly require anti-ice protection. I’ll add, that a bird-strike capable of damaging an engine, sufficient enough to shut it down, is not a single bird. It’s a flock of birds. That same strike on a screen would likely a) destroy th...Jump to post
In deed. Figuring that out quicker would be helped a lot by having more judges for it, which would also help the people truly needing asylum, as it would cut down the time of uncertainty. best regards Thomas I don't disagree with you Tommy, but that's not what I meant when I asked the question.

No, that's not what it means. The fact that one is seeking asylum proves that they've not been granted asylum, which means the legality of their presence in this country is questionable. Not quite. An asylum seeker does have some legal status, and is not necessarily an illegal alien. The problem is...Jump to post
Republicans have been doing it for years. Y'all weren't outraged then. In fact, it was encouraged and applauded. All the name calling, harassing, bullying, death threats, and murder.

Mitch McConnell is the actual Senate Majority leader. He decides what bills should be debated and brought up for a vote. Health care? no. Environmental bills? no. Voting rights? no. Gun control? no.

What was it like for the Routemasters to tow the luggage trailers at 70 mph. I'm not sure I understand what you're asking. If the trailer is properly loaded, it's a non-event, assuming the tow vehicle & trailer are capable of, and stable at 70mph. If the tow vehicle can't make 70mph, then it do...Jump to post

So we are supposed to be outraged over a CNN host but not two people who have actual power and deny there is voting issues and health care issues and racial issues? Actually, I'm not outraged.

Which is of course the same as the pressure of the hydraulic fluid in the reservoir. Which, is of course, controlled by the air pressure in the reservoir. On aircraft where air is used to pressurize the reservoir, we measure and regulate air pressure, not hydraulic pressure, in terms of head pressu...Jump to post
Air pressure? Or hydraulic fluid pressure?
Presumably, cavitation would cause hydraulic-fluid-bubbles, rather than air bubbles, correct?
Thanks guys, another follow-up question. I’ve heard the term “hydraulic head pressure” mentioned a lot while trying to get an answer to this question. What does that mean? Thanks again Really, really simple, in hydraulics, head pressure is the pressure exerted on the system by the fluid above the s...Jump to post
You will probably need to specify country, regulating authority and operator if you want an answer that means anything to you.

It’s a sight target. When the pilots’ eyes are aligned to it, they are in the “proper” position.
When teaching taxi, I used to explain that when aligned to the target, all the sight lines and angles in the AMM and taxi manuals were valid.
All the aircraft I have worked on ranging from the BAC One-Eleven through to the A350 have a pneumatic system that runs a 45/50 psi. I don't call that very high I think we had this discussion before. From a maintenance point-of-view, chapter 36 air is indeed low pressure. High pressure, to the main...Jump to post
Simply, the plumbing is designed and rated for 3000 psi...actually a lot higher than that. The pneumatic ducting is rated for much lower pressure...probably in the 200-300 psi range at the engine and lower as the air progresses through the airframe. Locations where high pressure air is used, e.g. ac...Jump to post
I was talking more like a horse trailer, U haul trailer, or boat trailer rather than an articulated bus. As long as the tow vehicle and hitch system are rated for the weight of the trailer/load, then it’s not a problem. Acceleration may be slower, and stopping distances increase, but that’s to be e...Jump to post
What does that mean? What exactly is it like towing a loaded trailer with a bus of any kind like a full sized bus or a small shuttle type bus. It is exactly like towing anything.

I think you're speaking of the Fan air valve. The Fan air is used while sitting stationary while on the ground. The Fan Air is no longer needed after takeoff thus the valve closes and Ram air takes over. No, the fan air valve opens or closes in response to bleed air temperature. It allows fan air t...Jump to post

Taxied back, or pulled back in? Not sure of ramp procedures in SFO, but it could be possible that the access door for the air cart was left open, so they pulled back in, dealt with it, and pushed again. Around here, it’d be no big deal for the dude to walk out and deal with it, but different airport...Jump to post
We moved from AT&T to Verizon a little over 10 years ago and ported my wife’s Blackberry over. I don’t recall it being an issue at all.

As I understand it, it is illegal to record anyone without consent, unless it happens in a public place (e.g. filming of a police officer or a crowd of protesters).
