The Flight Nerd Weekly Briefing: October 20, 2026

01: COCKPIT VOICE RECORDER

Fall is officially here: the air is smooth, the leaves look great from 2,500 feet, and the morning METARs have started their annual habit of saying "CLR" right up until they say "FG." The FAA also had a busy week. It told Centennial's hangar tenants that an 82% rent hike is just fine, grounded every Elixir trainer in the country, and announced it's putting air traffic controllers back in the jumpseat. Oh, and the Thunderbirds are three weeks away from performing over the runway where the Space Shuttle used to land. Grab your coffee and pull up a chair. Unlike the fog, this one won't burn off by 10 a.m.

02: RADAR CONTACT

Centennial Strikes Again: The FAA Says an 82% Hangar Rent Hike Is "Fair and Reasonable"

Last week Centennial Airport (KAPA) was in the news for losing its touch-and-goes. This week it's the hangars. On October 7, the FAA ruled against a Part 13 complaint from the Centennial Airport Pilots Association and decided that Denver jetCenter raising T-hangar rent from $660 to $1,200 a month is "fair and reasonable." AOPA says 15 of the 45 hangars emptied out when the new rate took effect, while comparable T-hangars at nearby Broomfield go for around $450 to $475. AOPA asked the FAA to reconsider, and the agency said no. Its position is that tenants have to bring the cost and financial data to prove a rate is unfair, even though the airport and the FBO are the ones who hold those records.

The so-what: the ruling sets a precedent, and AOPA's general counsel expects other airports to try big increases now. Salt Lake City is already on deck, with single-hangar rates jumping 84% in January. If you own or plan to own an airplane, hangar costs are a bigger long-term ownership expense than most people budget for. And the FAA has now signaled it won't check the math for you. Want a heads-up before it hits your field? Find your airport's AOPA Airport Support Network volunteer now, not after the rent letter shows up. (AOPA)

The FAA Just Grounded Every Elixir in America (All Three of Them)

The FAA issued an emergency airworthiness directive grounding all Elixir Aircraft Model Elixir airplanes, the French-built two-seat composite trainer, effective October 14. It follows a fatal accident during a production flight in France on October 1, after which EASA grounded the European fleet on October 2. There's no approved inspection or fix yet. Special flight permits to ferry an airplane somewhere are generally off the table too, and the FAA calls the AD an "interim action" with comments open through November 27.

The so-what: three airplanes is a small fleet, but how this AD works is a great lesson. An emergency AD skips the usual comment-first process because the FAA believes the unsafe condition is serious enough to stop flying immediately, and it applies "regardless of certification category." For student pilots, this is a real-world look at a topic that shows up on the written and the oral: ADs aren't suggestions, and checking AD compliance is part of how you confirm an airplane is airworthy. (More on that in Pattern Work.) (AVweb)

Controllers Are Getting Back in the Jumpseat, and GA Cockpits Are on the List

The FAA is bringing back its Flight Deck Training program, developed with NATCA, which lets air traffic controllers volunteer to ride along in commercial, general aviation, and military cockpits. The program went on pause when the pandemic hit, and FLYING reports it will formally restart after Thanksgiving. The goal is to give controllers a firsthand look at pilot workload and at how their instructions land on the other end of the frequency.

The so-what: every pilot has gotten a clearance that made perfect sense on a radar scope and none at all from the left seat. Think "turn left heading 270, descend and maintain 2,500, contact approach 124.35, and report the airport in sight" while you're in the bumps at 120 knots. A controller who has watched a pilot juggle that is a controller who might space it out next time. GA being on the list matters: the Cessna pilot in a busy Class C is exactly the workload controllers rarely get to see. If your flight school or local FBO gets a request, say yes. It's the cheapest safety improvement in years. (FLYING)

03: BRIEFING ROOM

The Fall Morning Fog Trap: Read the Spread, Not the Sky

Picture a Saturday in late October. You've got a 7:30 a.m. leaf-peeping flight booked, and the 6:53 METAR looks perfect: wind calm, 10 miles visibility, sky clear, temperature 8, dew point 6. You're already picking out your sunglasses.

Look at those last two numbers again. A clear sky and calm wind mean the ground has been radiating heat away all night, cooling the air right above it. A 2-degree temperature/dew point spread means that air is very close to saturation. That's the textbook setup for radiation fog, and here's what the textbook leaves out: radiation fog often gets worse right after sunrise. The first bit of solar heating stirs a little mixing into that shallow, saturated layer, and you can watch your 10 miles become a quarter mile while you're doing the preflight. Airports in river valleys and low spots fill in first, because cold air drains downhill and pools there.

The habit that saves you is looking at the trend, not the snapshot. Pull the last three or four METARs. If the spread has gone from 6 to 4 to 2 overnight, it's still closing, so plan accordingly. And know where you'd divert before you ever take the runway. Fog doesn't care that your destination was clear when you left.

DPEs love this one on the oral. "The weather's VFR, is it a go?" is a trap question. The answer they want sounds like "VFR right now, but the spread is closing, so here's my plan."

04: FLY-IN RADAR

Two great shows, same weekend, opposite ends of the Gulf. Pick your coast.

Salute to America in Space | November 7-8, 2026 | Kennedy Space Center, FL

The U.S. Air Force Thunderbirds headline an air show at Kennedy Space Center's historic Shuttle Landing Facility, the same runway the orbiter landed on. They're joined by the NASA Freedom 250 Aerial Team, the C-17 Globemaster III Demo Team, an F-104 Starfighter, and F-18 Super Hornets, with more acts still being added. On the ground you'll find NASA's ER-2 high-altitude research jet, a NASA F/A-18B, and an RS-25 rocket engine. The show is part of NASA's larger MAX POWER expo that weekend, which also includes astronaut speakers and behind-the-gates bus tours to the Vehicle Assembly Building and the Apollo Saturn V Center.

Insider tips:

• Everyone rides in one car. Each ticket order comes with one parking pass, everyone in your group has to arrive in the same vehicle, and the pass needs to be printed out. You enter through the North Gate via Titusville Road, and every vehicle goes through federal security screening. One prohibited item gets the whole car turned away, so clean out the glovebox and trunk before you leave home.
• The air show ticket covers the air show only. It doesn't get you into the Kennedy Space Center Visitor Complex, and the MAX POWER bus tours are ticketed separately through NASA. If you want the VAB tour, book it on its own.
• Bring a chair, not a canopy. General admission doesn't include seating, personal tents and canopies aren't allowed, shade is limited, and coolers aren't permitted (you get one sealed water bottle, up to a liter). Pack sunscreen, ear protection, and a small handheld umbrella for shade. Gates open at 9 a.m., and the flying runs from noon to about 4 p.m.

Texas Capital Air Show | November 7-8, 2026 | San Marcos Airport, San Marcos, TX

This one was supposed to debut last fall, until the 2025 government shutdown canceled it, so this is a first-year show with a year of pent-up demand behind it. The lineup includes the USAF F-22 Raptor demo and a four-ship of F-16s, plus a serious warbird roster: the B-25 "Yellow Rose," the C-47 "That's All, Brother" (the airplane that led the main D-Day paratrooper drop), a P-51 Mustang, an FG-1D Corsair, an FM-2 Wildcat, a TBM Avenger, and a T-33. Also on the bill: the NextGen Eagles, Bob Carlton's FoxJet glider, and a Coast Guard MH-65. All proceeds go to the Wings & Warriors Foundation, which works on suicide prevention for military members and first responders.

Insider tips:

• The morning is your ramp time. Gates open at 9:30 a.m., but the flying doesn't start until noon. That's two and a half hours to see the warbirds up close, so use them for the static displays and save your seat-hunting for later.
• First-year shows have first-year traffic. Nobody has driven this parking plan before, including the people running it. Arrive close to gate opening, check the parking page on the official site the night before, and expect the drive out after the F-22 to be the slowest part of your day.
• Flying in? Check the NOTAMs early. Air shows come with temporary flight restrictions, and arrival procedures for a first-time event may get published late. Check NOTAMs for San Marcos (KHYI) in the days before the show and again the morning of.

05: PATTERN WORK

Four questions this week, all from the FAA's own playbook: one warm-up, two solid middles, and one that has fooled plenty of instructors. Answer key at the bottom. No scrolling ahead.

1. (Warm-up) Which set of conditions is most favorable for radiation fog to form?

A) Warm, moist air moving over a colder surface

B) A clear sky, little or no wind, and a small temperature/dew point spread

C) Moist, stable air being pushed up sloping terrain

2. Under 14 CFR 91.403, who is primarily responsible for keeping an aircraft in an airworthy condition, including compliance with airworthiness directives?

A) The mechanic who signed off the last annual inspection

B) The owner or operator

C) The FAA

3. Which type of fog can form or even thicken with winds up to about 15 knots, and is most common along coastlines?

A) Radiation fog

B) Advection fog

C) Steam fog

4. (The hard one) It's November. You haven't flown at night in four months. One evening, you make three takeoffs and three full-stop landings, finishing the last one 45 minutes after sunset. The next night, can you carry passengers at night under 14 CFR 61.57(b)?

A) Yes. All three landings were full-stop, and they were after sunset.

B) Yes, as long as all three landings happened after the end of evening civil twilight.

C) No. None of those landings happened in the period beginning 1 hour after sunset.

Tally your answers. The key (and a scoring guide) is at the bottom of the issue.

06: SQUAWK BOX

Here's one for the dinner table: Space Shuttle commanders didn't learn to land the orbiter in the orbiter. They learned in a Gulfstream II business jet that NASA had modified to fly like a falling brick. To match the shuttle's steep, unpowered dive toward the runway, the Shuttle Training Aircraft flew its approaches with the main landing gear hanging down and its engines in reverse thrust, in flight, descending at an angle around 20 degrees. A normal airliner approach is about 3. Every shuttle commander flew at least 1,000 of those practice approaches before landing the real thing. Next time your CFI asks for one more pattern, remember it could be worse.

And the observation: every pilot has looked at a 6 a.m. METAR with a 1-degree spread and said, "Eh, it'll burn off by the time I get there." The fog said the same thing about you.

That's the stack for this week. Between hangar bills, fog banks, and controllers learning what our side of the radio feels like, it's a good week to be the most prepared pilot in the room. Go read a few METARs for fun. We won't tell anyone.

07: PATTERN WORK ANSWER KEY

Scoring guide:

• 4/4: Flawless. You can tell sunset from civil twilight from "an hour after sunset" without a calculator. Examiners fear you.
• 3/4: Strong. If you missed the night currency question, so has half the hangar.
• 2/4: Ceiling's a little low but you're still VFR. Another lap through weather and regs and you're golden.
• 0-1/4: Visibility reduced in fog. It burns off. So will this.

1. Answer: B (A clear sky, little or no wind, and a small temperature/dew point spread). Radiation fog forms when the ground radiates heat away overnight and cools the air right above it to its dew point. Clear skies let that heat escape, and calm or very light wind keeps the cooling concentrated in a shallow layer near the surface. Choice A describes advection fog, and choice C describes upslope fog. Radiation fog forms over land, not water, since water surfaces cool very little overnight.

2. Answer: B (The owner or operator). 91.403(a) puts primary responsibility for maintaining an aircraft in an airworthy condition, including compliance with Part 39 airworthiness directives, on the owner or operator. The mechanic is responsible for the work they perform and sign off, not for tracking every AD for the airplane's whole life. And separately, under 91.7, the pilot in command has to decide whether the airplane is in condition for safe flight before every flight. That's why "show me the AD compliance records" is a fair question on a checkride.

3. Answer: B (Advection fog). Advection fog forms when warm, moist air moves over a cooler surface, which is why it's common along coastlines where ocean air drifts over colder land or water. Unlike radiation fog, it can develop and even deepen with winds up to about 15 knots. Stronger winds usually lift it into a low stratus layer. It can also form in the middle of the day and hang around far longer than radiation fog, which is why the Pacific coast can sit socked in while inland airports are wide open.

4. Answer: C (No. None of those landings happened in the period beginning 1 hour after sunset). This is the classic "three different nights" trap. Under 61.57(b), to carry passengers between 1 hour after sunset and 1 hour before sunrise, you need three takeoffs and three full-stop landings within the preceding 90 days, made during that same 1-hour-after-sunset period. Landings at 45 minutes after sunset don't count, no matter how dark it looks. Meanwhile, under 91.209 your position lights have to be on from sunset to sunrise. And under 14 CFR 1.1, the "night" you log in your logbook starts at the end of evening civil twilight. Three regulations, three different definitions of night. Choice B gets the logging definition right but applies it to the wrong rule.

If you'd like the "three nights" problem and the rest of the regs sorted out for good before test day, the Private Pilot Ground School course covers the full written exam syllabus: flightnerdairforce.com/private-pilot-ground-school-lifetime-access
