>One of my favorite station IDs was an independent local analog UHF channel 56 with call letters WLVI. Bangor, ME has an ABC affiliate WVII broadcasting on VHF channel 7.

Rochester NY has WXXI for a PBS station on channel 21. It is also curiously reused as the call sign on local AM and FM NPR radio stations. For whatever reason that is allowed.

The FCC generally allows stations that share ownership to use the same callsign for TV, FM, and AM. Not always in the same area either; KCBS-AM is in San Francisco, while KCBS-FM and KCBS-TV are in Los Angeles. Additionally, stations are allowed to keep their call sign when ownership changes, so even though KCBS-FM and AM are no longer owned by the owners of KCBS-FM, they have chosen to keep the same call signs.

Non-USA resident here. Can someone explain all the four-letter news station names to me? Why not brand them with something more memorable / locally nuanced?

Other posts covered the details. Similar to the airport codes, just national instead of international...

WRC-TV - NBC Washington

similar to...

KIAD - Dulles International

The other thing that might not be obvious to non-residents is that K is for West of the Mississippi, and W is for East. It must be weird to live near the Mississippi and get a mix of K and W station call signs!

W is for East. What a country!

Originally W was supposed to be for the West side, but there was a bureaucratic screw up and they were switched.

As for why K and W, nobody is sure why those two letters, but it might be related to Morse code.

Just to nitpick, this landing technique is something every pilot has to demonstrate to an FAA designated examiner to get their first pilot certificate (or, the private pilot license). So it's kind of like saying "Wow, you did the thing every pilot has to do!". I get what you're saying though - there's an emotional difference between doing this when everything is fine and when you have a real emergency.

I suspected it wasn’t required for every pilot since most initially licensed pilots will train on airplanes that don’t have retractable landing gears in the first place. But I guess the technique isn’t much different than if your nose tire blew, which might be included in all training? Looks like flying with a retractable landing gear is a separate “complex aircraft endorsement” that “has no corresponding check ride…

The technique is the soft-field landing technique, required for every pilot[1]. It's for landing on soft surfaces such as a grass strip. You must land with the mains first and keep the nose wheel held off of the ground for as long as possible, gently setting it down. You don't need a complex aircraft for this.

This is the same technique the delta pilot used, and by other pilots that had an abnormal nose-wheel deployment.

You'd gain nothing, they can already see it with their eyeballs, and they don't require anything else like faster response or a different viewpoint. You'd lose in terms of putting another hole in the aircraft and maintaining another system, and you'd still need the manual procedure in case the camera didn't work.

>and you'd still need the manual procedure in case the camera didn't work. And presumably if the camera doesn't work as part of the pre-flight checklist for whatever reason, you're not going anywhere until it's fixed/replaced.

camera would probably just get an INOP sticker put somewhere, a surprising number of things can be nonfunctional on an airplane before it's grounded.

part of it is that there's a backup for most everything required.

There is an algorithm for everything in aviation. If you suspect your landing gear is not functional, you typically fly by a tower and have them make visual confirmation. Then you have another algorithm (they call them procedures) for how to land without gear. The airport likewise has a checklist of everything to do in this case. All of these procedures are hard won, the NTSB uses every hull failure and fatal acciden…

When you are robotically rolling to unload Gs does it still make your heart go boom!?? I love the idea of flying. I see crop dusters and private planes flying in all the time and it makes me wonder if I ought to try it out.

Did they know in advance that they were having problems? Edit: Answer: Yes ... the crew initiated a go around due to a unsafe nose gear indication, climbed to 4000 feet and entered a hold to work the checklists. After working the checklists the crew declared emergency and requested emergency services on stand by. The aircraft performed a low approach to runway 36L, positioned for another approach to runway 36L and la…

On of the more evocative things (esp. for those in the UK) was a Spitfire helping out a Vulcan (XH558 no less) with nosegear issues in 2015.

Wow! Phenomenal piloting skills. In the 2nd video on the page taken by a passenger during landing, you can hear the plane balanced on the rear wheels for 12 seconds before touching down the nose. Impressive!

This is a pretty standard maneuver - it's similar to a "soft field landing" (eg grass runway). Assuming you have a long runway, you avoid braking since that would slam the nose down, and use more and more elevator to keep the nose up to as slow a speed as possible.

How does a plane lose its front landing gear?

It was there, it just wouldn't drop into place.

I have seen (on one of the YouTube ATC channels) a comercial jet (747, IIRC) that DID lose one of its main landing gear on take-off. Another pilot (in another jet) saw the wheel bounce across the runway.

That plane continued on its way and landed normally. It was just one wheel of a four-wheel truck/assembly (of which a 747 has 4 sets).

I got my CPL the same year my first kid was born. The procedure/checklist culture transferred really well between baby tasking and training.
