Three aircraft have been certified with Emergency Autoland (EAL) systems in 2020: the Piper M600, the Daher TBM 940, and the Cirrus Vision Jet SF50.

EAL systems can perform an emergency landing in the event of suspected pilot incapacitation. When these systems are activated, the autopilot will begin to announce its intentions on air traffic frequencies. Here’s what other pilots in the area should know about EAL systems.

EAL can be activated in three ways:

  1. EAL senses erratic flying, stabilizes the aircraft, and checks for pilot responsiveness; if no input, EAL activates.
  2. Emergency Descent Mode (EDM) activates. After descending, EAL checks for pilot responsiveness; if no input, EAL activates.
  3. EAL can be manually activated by a pilot in distress or a passenger.
EAL will squawk 7700 and broadcast a Mayday advisory on the aircraft’s last pilot-selected frequency and on Guard (121.5) as follows:

“Mayday, Mayday, Mayday, November One Two Three Four (N1234), Emergency Autoland activated, standby for more information.”

After the initial broadcast, there will be a 25-second pause for Air Traffic Control (ATC) to move conflicting traffic. Twenty-five seconds after activation, EAL broadcasts the following:

“N1234, pilot incapacitation, XX miles southwest of KABC, landing KXYZ airport. Emergency Autoland in XX minutes on Runway 00.”


The aircraft then begins maneuvering to the selected landing airport.

Subsequent broadcasts will be on Guard. After initial activation, it will immediately broadcast on Guard if EAL changes destination due to weather or other factors. As necessary, the aircraft descends in the hold at the final approach fix for landing at the emergency airport.

EAL will broadcast on the appropriate ATC frequency or Common Traffic Advisory Frequency (CTAF) within 12 miles of the landing airport. Subsequent broadcasts at intervals repeat information and update time to landing. After landing, EAL broadcasts at 90-second intervals on Tower/CTAF and 5 minutes on Guard as follows:

“Disabled aircraft on Runway 00 at KXYZ airport.”

Once activated, the EAL system will make verbal announcements to passengers in the cockpit on upcoming maneuvers, and indicate the route of flight and ensuing maneuvers via a video map display. A push-to-talk button is available for passenger communications to ATC.

EAL will avoid: prohibited areas; known obstacles and terrain; and significant weather.

EAL does NOT:

  • Check Notices to Airmen (NOTAMs) (e.g., closed or shortened runways).
  • Avoid Military Operations Area (MOA), Special Use Airspace (SUA), Restricted Areas, or Temporary Flight Restrictions (TFR).
  • Turn on aircraft lights (lights that are already on when EAL activates will stay on).
  • See and avoid other traffic.
    • Traffic Alert and Collision Avoidance System (TCAS) is not linked to EAL.
EAL Operational Considerations:

  • Only selects airports with a published Global Positioning System (GPS) or Area Navigation (RNAV) Approach
  • May cross international boundaries
  • Does not exit the runway
  • May land opposite direction to current traffic
  • Does not receive braking action reports
  • Does not know about personnel and equipment on the runways
  • Will not alter route of flight per ATC instructions
  • Must have a terrain database loaded (may be out of date)
The EAL system selects a suitable landing airfield based on several factors: weather, wind, runway length, and towered/non-towered airport status. EAL selects towered airports over non-towered airports where possible, and uses runway requirements that depend on the aircraft type. If the system loses the GPS signal, the airplane continues straight flight without attempting to land until GPS coverage resumes.

-- all the more important to monitor Guard as more of these things comes into play
 
I can just see the thing piping up while I'm flying asking if I'm incapacitated. It's bad enough that my truck asks me from time to time if I have my hands on the wheel.

As an airport operator, those parts cause a little concern. I realize its probably a technological limitation as there isn't currently a good way for the EAL to access and process such information. A runway could be closed for construction, with open trenches, lots of heavy equipment and operators, etc., and those people more than likely will have no heads up a "pilotless" aircraft is headed their way.

I do love the intent behind the system. Its definitely peace of mind for the non-pilot passengers that accompany us on our adventures. Something happening to me has always been my wife's concern.

Fortunately its a system that probably will see limited use, pilot incapacitation is relatively uncommon. Probably more so in the type of aircraft that has it built in.

Does auto land switch fuel tanks?
 
Hopefully the dudes selling it have lol.
i am sure they did. in fact in one of the webinars they mentioned that this was in the making for about 10 years now and initially they tricked the system to create a runway in the sky at 5k or so and tested it there...
 
I wonder how long before some dude tries this in real world without an actual emergency.


I'm wondering how you could not, lol.

These systems are installed in some pretty sophisticated aircraft so I suspect that communicates to someone (i.e. via datalink) that it has gone into autoland mode. That said, I'm sure there must be some way to test it (minus the emergency radio broadcasts described above).

Dumb question #809.

Wouldn't you just be able to fly out to a rural uncontrolled airport that meets the landing criteria. Pull flight following. Tell atc you are going to test it. Then announce the same on guard. Finally a message on CTAF. Then just do it.

How many violations would that "announced test" result in?

For those who have not seen this yet, 15 minutes long but interesting and informational.

If people are working on a runway and no one's monitoring a frequency, they are indeed in danger, not only from planes with autoland. It'd be nice if there was a way for the autoland system to avoid closed runways, but any such system would be inherently limited.
 
I'm sorry Dave, I can't do that. You've been flying erratically.

That is often the case on closed runways. Construction crews rarely if ever have a radio, that's why the runway is closed.
 
Just to add on above, fuel management in the Piper M600 is also automated.
