Frantalone's Hardware and Garden Stores brings you garage logic podcast number 773

January 18th, 2022. 48 degrees was the record high for this day and that was in 1891 and it was 36 below in 1887.

And now from the mayor's office above the boat house on the east shore of Spoon Link.

It's garage logic with rookie on production Chris Reavers, director of social media John Hyde in the newsroom and occasionally Kenny from the Krabby coffee shop.

Here is your flashlight king fireworks commissioner and keeper of common sense. Your mayor Joe Sushare.

I knew all the GL pilots would help us. Oh yeah.

Yesterday we got news of the FAA apparently arranging now for commercial airliners to land in a gradual descent instead of a step process where they'd go a little ways lower, go a little ways lower and

the plane pause. Yeah and I was wondering if that's so great. Why, why have they only been doing, why are they starting it now and a car all down in

Northfields a long time experienced pilot both military and commercial on the January 17th podcast. You are wondering why if steady descent rate approaches are so great.

Why haven't the airlines been doing them for years short answer. The autopilot technology and the FAA radar precision wasn't good enough until about 10 years ago.

Long answer beginning with the phone 757 and Airbus 320 airliners in the late 80s and early 90s.

All of the cockpit instrumentation switch from analog to digital electronic instruments.

The autopilot snows aircraft are much more sophisticated than what was previously available.

The really large congested airports such as Los Angeles Dallas Miami and Chicago needed a better way to land aircraft and increase the frequency of landings and takeoffs.

The FAA came up with the continuous descent approach that was planned to work with the vertical navigation function of modern autopilots.

Although pilot training today is as good as you would hope it could be a human pilot cannot fly an airliner with the precision required to meet all the requirements of a vertical navigation approach.

The adoption of GPS navigation by the airlines and improved radars by FAA now allow a totally automatic approach from 35,000 feet right down to the runway.

When flying from Minneapolis to LA, the FAA controllers will start sequencing aircraft to land on a specific runway and at a specific time as far away as Denver.

The pilot is obligated to comply or the aircraft will be denied access to the LA airspace.

If everyone does their job the system works wonderfully.

But if some pilot for cheapo airlines misses the altitude and airspeed assigned over Riverside for example,

it will follow things up for everyone behind him and those waiting to take off.
