Erau flight business model l.jpg

ERAU Flight Business Model

  • The university is a privately funded “non-profit” institution.

    • Flight training is considered a revenues neutral “lab” for our students.

    • Safety and educational excellence are the priorities!

    • University leadership is actively involved!

  • Flight safety does not have to vigorously compete for dollars

    • Risk mitigation is a priority.

    • Residual risk acceptance levels are relatively low.

    • New equipment and technology embraced.

“Where the Eagles Fly”

The safety of our students and flight instructors is our number one priority l.jpg

The “Safety” of our students and flight instructors is our number one priority!

  • Independent University Safety Oversight

    • Students, instructors, and staff are actively involved in all aspects of the flight safety program!

  • In- house maintenance

    • “perfect” aircraft!

  • Active 24 hour flight supervision

  • Entire Fleet is ADS-B Equipped

A little history l.jpg

A Little History

Accident occurred Friday, September 15, 1995 in NEW SMYRNA BEACH, FLAircraft: AEROSPATIALE TB-9, registration: N117ERInjuries: 3 Fatal, 1 Uninjured. The Aerospatiale TB-9, N117ER (Embry Riddle) , was observed on short final approach, and the Piper PA-38 (Non Embry Riddle) had turned from base to final just above and behind the TB-9. Two pilots on the ground transmitted warnings to the aircraft but no action was taken. The aircraft collided; the TB-9 sustained stabilator damage and nosed down and crashed. The Piper landed without further incident

The National Transportation Safety Board determines the probable cause(s) of this accident as follows: the failure of the pilots of both aircraft to see and avoid each other.

And a little more l.jpg

And a little more

Accident occurred Friday, December 03, 1999 in DELAND, FLAircraft: Piper PA-28-161, registration: N153ERInjuries: 4 Fatal. After the Cadet airplane departed, the flight proceeded to the DeLand airport and remained in the traffic pattern for runway 05; The Seminole (non ERAU) flight continued on the VOR approach; the last radar target of the Seminole was approximately .6 nautical mile from the approach end of runway 23. Several individuals heard the Cadet flight announce on the DeLand CTAF that the flight was departing runway 05. The airplanes collided in-flight near the departure end of runway 05; the wreckage of both airplanes came to rest within approximately 1/2 nautical mile from the departure end of runway 05.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:

The inadequate visual lookout by the pilot-in-command (PIC)/certified flight instructor (CFI) of both aircraft. Contributing factors in the accident were: 1) the frequency congestion of the CTAF 2) the poor in-flight planning decision by the PIC/CFI of the Seminole for his continuing a practice instrument approach to within approximately .6 nautical mile from the approach end of the runway with opposing airplanes departing on the upwind leg, and 3) the absence of guidance in the Aeronautical Information Manual and Advisory Circulars as to how or when to terminate a practice instrument approach to an airport that does not have an operating control tower.

Return on investment l.jpg

Return on investment!

The next five slides depict an actual save between two ERAU aircraft using ADS-B.

Note that 491ER is a high wing climbing from a lower altitude.

N712ER is a low wing aircraft at a higher altitude.

The incident resulted from a blocked/ misheard radio transmission.

The manuevers were begun using ADS-B and completed visually.

Slide27 l.jpg

Has the investment in ADS-B been worth the dollars expended?

What s next l.jpg

What’s next?

  • ADS-B cost should decrease and availability should increase.

  • General Aviation should embrace the technology as these events come to pass.

  • General aviation should have a strong voice in

  • deployment and utilization of the technology.

    • The needs of GA may be different than air carrier requirements?

    • The term “uncontrolled airport” should be examined?

    • The pilot controller relationship should be examined?

    • ADS-B can significantly improve safety below 10,000 feet.

    • GA has a strong experience base in ADS-B
