Aviation Safety Tribal Knowledge

 06 Jun 25:

From AOPA, who reshared them from other sources:

These time-honored quotations reveal the topics pilots think (and talk) most about: emergencies, aeronautical decision making, aircraft design, and flying technique. And many are imbued with exaggeration and flying’s pervasive gallows humor.

“Any landing you can walk away from is a good one.”

“Any landing where the airplane is reusable is a great one.”

The meaning of most of these maxims is obvious, but some include subtle messages, too. Here, in no particular order, are some of the most widely circulated.

Aerial emergencies:

“The first thing to do is wind your watch.”
Think things through, and don’t make a bad situation worse by compounding the problem. Get the checklist out, consider your options, and don’t rush.

“In an emergency, undo the last thing you did.”
Sometimes pilot actions produce seemingly unrelated problems. For example, if your airplane starts an uncommanded roll to the left moments after you turn on the cockpit heater, try turning off the heater—even if those two actions seem to have nothing to do with one another. Sometimes correlation really is causation.

“If faced with a forced landing, fly as far into the crash as possible.”
Aviation icon and test pilot R.A. “Bob” Hoover said this, and he would know having survived multiple aircraft accidents during his long and storied career. Whatever happens, the priority is to maintain control of the aircraft.

“Keep flying until the last part stops moving.”
Don’t give up, even when a situation seems dire.

“It’s Bernoulli that matters in an emergency—not Marconi.”

Concentrate on the physics (defined by Daniel Bernoulli) of flying the airplane, not talking on the aircraft radio (invented by Guglielmo Marconi).

“Aviate, navigate, communicate.”
Fly the airplane first. Then find your way. Once those things are accomplished you can talk on the radio.

Fatalism:

“Time to spare, travel by air.”
Yes, flying is plagued by weather, mechanical, and other delays.

“If the engine quits at night, turn on your landing light. If you don’t like what you see, turn it off.”
Dark humor. Besides, your airplane may not have electrical power after the engine quits. (More “dark” humor, as it were.)

“The second happiest day of your life is when you buy an airplane. The happiest is when you sell it.”
This is only true of some airplanes, not all of them, sometimes due to cost and maintenance. Pilots often feel deep and lasting regret after selling an airplane.

“If it ain’t Boeing, I ain’t going.”
Grammatically questionable Airbus shade.

“Please God, don’t let me [mess] up.”
Also known as Chuck Yeager’s prayer, but originally said with a potent F-bomb.

Illustration by Robert Neubecker.Aeronautical decision-making:

“It’s better to be on the ground wishing you were in the air than in the air wishing you were on the ground.”
True—but being on the ground wishing you were in the air is still regrettable.

“Start at the NTSB hearing and work backwards.”
When considering a course of action, think about how you might try to explain it to the inquisitors if things go badly.

“Takeoffs are optional. Landings are mandatory.”
What goes up must come down. On a related note, “There are more airplanes in the ocean than submarines in the sky.”

“Better to land downhill than downwind.”
Beware downwind landings, particularly in tailwheel airplanes, because of the possible loss in directional control during rollout.

“Speed is life.”
This saying, coined by a U.S. Navy combat pilot, has broader aviation applications.

“Always leave yourself an out.”
Pilots need to have a Plan B. Not a bad policy for life on the ground, either.

"The only time you’ve got too much gas is when you’re on fire.”
Having lots of fuel provides options—but it’s possible to have too much of a good thing. Think heavy loads, high elevations, and hot days.

“There are old pilots and bold pilots, but there are no old bold pilots.”
Good point, but overstated. Old bold pilots do exist. They’re just rare (or lucky).

Aircraft design:

“Never fly the A-model of anything.”
This military maxim contains an irrefutable truth that aviation learns from bitter experience, and later versions of any aircraft are likely to contain improvements.

“An airplane that looks good flies good.”
Aesthetics matter. A Spitfire is sure to fly more gracefully than a Lancaster. But looks can be deceiving. A de Havilland Beaver and North American T–6 look bulbous, yet they’re delightfully responsive and well balanced in the air.

“There’s no substitute for horsepower.”
Amen. And no replacement for displacement. Excess power can get pilots out of tight situations.

“The Cub is the safest airplane ever made. It can just barely kill you.”
Yes. See previous quote about horsepower.

Technique

“Push forward and the houses get bigger. Pull back and the houses get smaller.”
Except when the airplane stalls, spins, or exceeds 90 degrees of bank.

“Pitch plus power equals performance.”
Aircraft attitude and power produce repeatable results.

“Fly it all the way to the chocks.”
Pay attention and stay engaged whenever the airplane is in motion.

“If you think you might be approaching a dock too fast, you are.”
Many seaplane pilots have learned this lesson the hard way, and they’ve got dinged and scraped floats to prove it.

“Never run out of airspeed, altitude, and ideas at the same time.”
Airspeed and altitude create energy and options for pilots. Landings are the only time pilots should intentionally lack both airspeed and altitude—but they should still have ideas.

“The three most useless things in aviation are altitude above you, runway behind you, and fuel in the truck.”
Same concept as the previous statement about airspeed, altitude, and ideas. Don’t pass up the safety margin that more runway, additional altitude, and extra fuel can provide.

NASA Aviation Safety Reporting System and Safety Management Systems

 26 Apr 25:

Working on SMS implementation and wondering how to get a reporting database up and running? The folks at NASA have been administering the Aviation Safety Reporting System (ASRS) for the FAA for almost 50 years now. Analysts have coded and archived over 2 million reports, and the deidentified report database can be searched online.

ASRS is the Global Gold Standard, compared to siloed databases that are accessible only be a few analysts. 7400+ Safety Alert Messages, 527 issues of the Callback newsletter, 7600+ search requests have been generated as a result.

We are peeking over the horizon at improved methods to create and communicate safety intelligence. One way is to share this QR code to the ASRS, on websites, business cards, stickers...who will be the first air operator to put a big graphic on the side of their aircraft? United?


Some folks are using QR code stickers placed on aircraft components to help guide mechanics to proper, up to date manuals. Creative! We use Adobe to generate free QR codes. 


FMI: https://asrs.arc.nasa.gov/report/electronic.html

Reporting is the key driver of risk management, Safety Risk Management is one of the Pillars of a Safety Management System (SMS). What is the future of SMS? System Wide Safety, which relies on reporting to create in-time aviation safety intelligence.

Fly Safe Fact Sheets and Cleared for Takeoff blog

25 Apr 25: 

The FAA has a website with Fly Safe Fact Sheets that cover a variety of General Aviation safety topics. The links take us to a 2 page fact sheet that is visually interesting, covers the high points and has links to additional references: 


There is also a link to the well designed Cleared for Takeoff blog:


Now if we can just get the name changes to "Fly Smart."

Take care in the air and keep a sharp lookout for traffic through the big glass panel, aka the windshield. Spring flying brings everyone out, most mid airs happen on beautiful clear days, especially around visual reporting points or in proximity to airports or near departure and approach corridors for commercial traffic.

Pop quiz: How far away from this hovering helo should we stay in our light GA airplane?


Fly Smart,

Collision Avoidance

Pilot's Role in Collision Avoidance
Collision Avoidance
Advisory Circular 90-48E

Remember Herb's Rules to Live By:
1. Use a Checklist.
2. Look outside
3. Never fly hard IFR in a single engine aircraft

Visual Scan and Collision Avoidance
-Most midair collisions occur near airports, during daylight hours and in VFR conditions. Early detection is crucial to avoiding collisions, since it takes about 12.5 seconds to realize you are on a collision course and to do something about it.

-Degraded physical condition = degraded vision.

-Environmental conditions such as night time and low visibility degrade vision.

-Vestibular and visual disturbances can create motion and visual illusions.

-Spend 2/3 to 3/4 of scan time outside cockpit.

-Proper visual scanning procedures, eye movements of 10 degrees, focusing one to two seconds on each segment of the sky, 60 degrees left and right, 10 degrees up and down. Day=central vision, night=peripheral. Know that central focal vision is severely degraded at night, so peripheral vision is needed.

-“See and avoid” concept requires vigilance be maintained at all times, regardless whether the operation is IFR or VFR.

-Poor scanning = increased collision risk.


-Proper clearing procedures in all phases of flight.

-Know your aircraft’s blind spots. Turn on all lights in the pattern, and keep in mind that folks using night vision systems may not see all of those lights due to wavelengths outside the NVS operating specifications.

Hanger Talk: There is something special about flashing the wing lights or ground handling lights at night at another aircraft that is off in the distance, like ships passing at sea. A special hello to fellow aviators.

-Know your blind spot, located in the central focal vision where the optic nerve attaches. That is why traffic that is on a constant bearing, decreasing range to your aircraft "suddenly appear." One example is the 2025 nighttime collision near KDCA Reagan National airport.

-Aircraft speed differential and collision risk, converging at 300 knots = 36 seconds to react.

-Greatest collision risk: Airways, VORs, within 25 nm of airports, enroute, at or below 8,000 feet, day, VMC.

“Clear left, clear right, above and below”

-Slow down and live is one defensive tactic, especially in the pattern. 

-"Look with your ears" also, listen to radio calls to build situational awareness of where the traffic is. If a tower is running split frequency operations with customers on both VHF and UHF frequencies, our awareness needs to be higher than whatever the highest level is. 

From the Advisory Circular:
"13.1 Scanning at Night. Scanning at night depends almost entirely on peripheral vision. This is due in part to the night-blind spot that involves an area between 5 and 10 degrees wide in the center of the visual field. A pilot can compensate for the night-blind spot through “off-center” viewing, which requires looking approximately 10 degrees above, below, or to either side of an object. To better perceive a dimly lit object in a certain direction, the pilot should scan the area around the object rather than looking directly at the object. Short stops of a few seconds in each scan will help detect the light and its movement. Note that conflicting ground lights at night increase the difficulty of detecting other aircraft. Also, avoid blinding others while taxiing by not using strobe or landing lights until on the active runway for takeoff. 

Note: Pilots utilizing a Night Vision Imaging System (NVIS), such as night vision goggles (NVG), must be aware that some light-emitting diode (LED) obstruction and aircraft anticollision lighting may not be visible through the NVG. When flying with NVG, pilots should also be looking around the binocular assembly frequently, outside of the NVG view, to detect lighting that may not be visible through the NVG."

Active Failures of the National Airspace System (NAS)

31 Jan 25:

Dr. James Reason's Swiss Cheese model is often used as a visual model to show how active failures work their way through the latent risk holes in defensive layers (controls) of a system.

(Image Credit: Unknown)

In the case of the recent midair collision over the Potomac, the holes in the National Airspace System (NAS) cheese were big enough to fly a Sikorsky Blackhawk through...

Investigators will quickly determine the Who What When Where and How of what happened in this tragic mishap. Now we must ask, Why? And keep asking, so that we can create solutions that eliminate the multiple severe hazards that exist within the NAS in latent form, in order to keep this from happening again.

PS: The 2 dimensional, static sliced cheese model gets us thinking about the challenge, while in reality all of the cheese is melted together as a fondue and moving through space and time.
