um excuse me posted:

Ft*lb is a gross unit of energy a lot because it's the same unit as torsional force. Confuses a lot of people for that reason. But to answer the question, you can use that to figure out if the brakes will be large enough simply by knowing a vehicles mass and speed. E=1/2mV^2. If the energy of the vehicle is greater than the energy rating of the brake, you need a bigger brake.

Why should this be a memory item for the pilot of the aircraft?

C-17 4 ship low levels 300' @ 300 KIAS. Won't even get into the SOLL2 missions.
C-130 air drop on NVGs with assault strip landings

C-146 and U-28 missions are generally classified.

C-5s have 26 yr olds in charge of international flights with (multiple) inflight 90k+ lbs of fuel onload.

To call anything C or U related boring seems a bit out of one's lane.

After having done both, you know whats boring? Flying 737s doing an ILS 2x a day. Thankfully, the benefits far outweigh the drawbacks.

To be fair helicopter pilots are crazy.

This is true. You also have guys who are great pilots and have paid their dues and then legacy airline HR departments will reject them for the most fickle reasons like “he’s got too much PIC time maybe he’s too set in his ways.” Then they’ll turn around and hire some 26 year old rich kid with only two jobs in his resume.

Speaking of which, I actually have one of these 20-something dudes in my facebook who was genuine bitching that he got assigned the MD88 at Delta. Literally all “I’m grateful for the job BUT I was expecting the 737 this is disappointing but oh well”

I was daydreaming I could telekinesis his smartphone to explode in his eyes

:lol: did that guy know anything about Delta?

I'd forgotten about Kent Wien, but he seems like he'd be a top quality guy to fly with.

Also, watching that video and seeing all the little quirky, glorious things the Mad Dog can do makes me sadder they'll all probably be gone (at least in the MD-80 form) by 2021, though the magic mirrors watching the compass might be a pain in the dick if you really had to lean on the mag compass itself.

At least Delta's keeping the MD-90s around a while longer.

With Boeing throwing temper tantrums and Trump in the White House it would not surprise me to see Delta flying them well into the 2020s because they can't get the C-series and A321s they ordered.

While it won’t be exactly the same sort of stress, I’m pretty sure that airline pilot is pretty far down the list of jobs that let you stay home a lot.

Sagebrush posted:

So why are they delivering so few? Just because there are no pilots, or because they're so expensive?

Probably because maintenance requirements for aircraft mean that some massive percentage of every plane they've built is still flying.

The new car market would be pretty hosed if used cars had their engines replaced every 5 years and the body didn't change.

edit: I mean you're flying the very first cessna 152 off the line and its looks all shiny. What do you think a 1977 model year car from detroit that student drivers drove every day would look like?

Future Flight out in Princeton, TX is one of the better PPG schools from what I've heard. I'm sorry to hear about your medical. Being out in the open is amazing! Canopy flight can be really rewarding as well. You'll love being on a ppg.

If you'd like to be able to fly a passenger with a fixed wing, you can obtain a private glider pilot license with a self launch endorsement. That can allow you to fly things like a Grob 109b or a Diamond HK36 while having a revoked medical.

The Diamond HK36 seems like a pretty amazing loophole.

That makes sense. It’s amazing he didn’t kill himself doing the lopsided maneuver he did at such a low altitude. I’m just amazed the thing could handle the Gs he pulled doing it.

I imagine he hit the "must overhaul aircraft if this is hit" g limit but thats different from the "airplane literally falls apart" g limit.

What I'm concerned about is the students who feel like they will be ready for an airline gig at 300 hours. That indicates a dangerous lack of self-awareness. I'm over 400 now and I still don't know jack poo poo; one of our former instructors who's just now upgrading to captain at Georgian admitted he felt the same way even after he'd got his ATPL. Being a safe pilot means realizing you always have new stuff to learn.

How many hours does the typical military transport pilot have when they hop in the right seat?

About 180, but the training isn't even remotely close to the civilian side of the fence.

Not looking to start a debate, but USAF pilots are soloing an 1100HP P-51 lite at 14-17 hours.... the infrastructure that allow the students to do that are cost prohibitive to the outside world.

--

I don't know if a solid 1,500 hours is the right number, but I really enjoy being on the plus side of that. I wish there was a more quantifiable way to make quality worth more. Personally, I learned more in one 2 hour military pattern only sortie than I have in 220 hours on the 737.

My point was more that an order of magnitude difference there probably means that congress and the FAA haven't put much thought into it.

They both had little experience flying into icing conditions... which clearly doing 1500 hours of pattern work at a flight school in Florida will help with

Yeah, the only thing I can think of is the captain was thinking "the plane is WRONG I can't be in a stall!" or he didn't realize what those systems are and what they do; either way, a big failure of training that goes beyond inexperience with icing conditions.

Which is why the FAA went with "he was fat and didn't have a CPAP" :psyduck:

Still, it seems like a total failure of HCI practice that the software doesn't go "hey, you just put in a value that's seventy degrees below what I'm reading as the external temperature. Are you sure that's right?"

Like, if the temperatures disagree that much, then either

a) you hosed up your input
b) you are deliberately messing with the computer to trick it into doing something abnormal, or
c) the sensors are reporting wrong data

and in any of those cases the pilot should be alerted to take extra care.

Also I would love to experience a full-power takeoff at -52C :getin:

I wonder what the record for the LC-130s serving the South Pole station is. Daily mean temperature in March when they stop is -53C.
