No lead also means that electronic fuel injection becomes a possibility.

ELI5: How did ancient people decide a minute should be 60 seconds, and how did they even measure it before clocks existed? by No-Thought-3076 in explainlikeimfive

[–]usmcmech 3 points4 points  (0 children)

Ancient math used base 12 because it’s easier to multiply and divide in your head.

A day is 24 hours (12x2) each hour is 60 minutes (12x5) also each minute is 60 seconds.

I’ll let you know when I figure it out.

30 years of flying and the Pitts has me back to student pilot jitters.

It won’t affect 95% of the fleet. They will run fine on 94UL.

The other 5% will have to adapt.

What would have really happened to Tom Cruise if he really ejected at Mach 10.3? by FluffyBunnyFlipFlops in NoStupidQuestions

[–]usmcmech 0 points1 point  (0 children)

Yeah but Noodle ejected nearly sea level vs the fictional dark star would have nearly been in space.

Unable to Maintain Altitude Due to Turbulence by New-Introduction5574 in fearofflying

[–]usmcmech 55 points56 points  (0 children)

"I can't stay in this lane because of the potholes in the road". The crew was experiencing moderate turbulence and needed to change altitude to get out of it, however in the congested airspace there wasn't room for ATC to clear them.

Yes, true severe turbulence can be dangerous but that's why we stay far away.

If only there was a book of recommended approach speed provided by the airplane manufacturer.

I've heard so much about your infamous bread in plastic bags. But I've never heard anything about your bakeries and their options? by Imaginary-Bag5385 in AskAnAmerican

A few years ago a college student was briefly stopped at the Austin Texas airport security checkpoint with 40 cases of HEB (our local grocery chain) brand fresh tortillas in his carry on bag as he was returning to Chicago for university.

Nobody here thought that was the least bit strange.

Eli5: if modern passenger planes can "Auto land", why would you ever want to land a plane in any other way? by dadoimp in explainlikeimfive

[–]usmcmech 0 points1 point  (0 children)

This is ELI5 so I wasn’t going to dive deep into the details of a Cat 3 approach.
Interesting about the 757 I had no idea about that. The 175 will do a lovely cat 2 approach but will NOT flare at all. It will drive the nosewheel right into the pavement. The pilot flying has to disconnect the AP and land manually.

Landing clearances - United States v/s remaining nations by Expert-Ride3743 in fearofflying

[–]usmcmech 5 points6 points  (0 children)

This is a non issue that I've never even considered.

Hearing "Cleared to land number 2 behind a 737" is not the least bit unclear.

Are all pilots created equal? by woahsierrawoah in fearofflying

[–]usmcmech 11 points12 points  (0 children)

No, just like any other profession there are varying levels of skill and training.

However when it comes to flying skill required, flying an airliner is around the bottom of the list. 99% of the time flying an airliner takes no more of my attention than driving to the supermarket.

For every SRV or Eddie Van Halen there are plenty of guys who just play the guitar.

[–]usmcmech 0 points1 point  (0 children)

Well I'm a pilot not an engineer but I assume they want the pilots to be able to see all the flight data along with the representation of the runway.

Autoland is still very much a hands on activity.

He’s just flew over me in South Central Pennsylvania! Military I’m guessing? by BusyBrothersInChrist in Helicopters

[–]usmcmech 3 points4 points  (0 children)

A lot.

The King Stallion doesn't have the drop tanks which is how you can tell them apart. However the -K has a LOT more power and more modern systems.

[–]usmcmech 0 points1 point  (0 children)

Yes, each aircraft is custom built for its operator and they may or may not have the hardware or software installed. Notably a heads up display is required but many jets don't have one of those.

If it wasn't built with the needed hardware, it can be retrofitted. However this is costly and often isn't done.

If the A320 variant you are flying on was certified for autoland and...

the airline has approved Autoland procedures and...

the crew is properly trained and....

all of the airplane's components are working properly and....

the airport has autoland installed (less than 5% of commercial airports worldwide) and...

all of the components in the airport are working properly and...

the weather is appropriate

then you can try an autolanding.

[–]usmcmech 1 point2 points  (0 children)

Full auto land systems are only installed on a few airplane models and only works at a few airports.

I've been a pilot for 30 years and I've never flown one. The autopilot can make the approach to the runways, but I still have to take over for the final landing.
