• The “Fruit” - Operational Credit
• Crew training and proficiency
• Glimpse into the future

Past | 14CFR §91.175
• Since 2004: Allowed for descent below DA/DH or MDA down to 100 feet above TDZE
using Enhanced Flight Vision System (EFVS) in lieu of natural vision
EFVS SEGMENT

14CFR §91.175 | Issues
• Regulation did not fully leverage
EFVS capability below 100’
• Regulation failed to offer
dispatch/continuance credit for
Air Carrier Operations
(91k/135/121)
• Regulation did not define
equipment requirements nor
contain provisions for product
improvement (better EFVS
technologies)
• Regulation did not address
training nor recent flight
experience requirements

• Permits EFVS operational credit below 100
HAT
• Permits air carrier dispatch/continuation credit
• Defines equipment requirements
• Defines equipment certification requirements
• Defines authorization requirements
• Defines training/proficiency requirements
New | FAA Advisory Circular 90 – 106A

New | 14CFR §91.176 (b)
• Allows for descent below DA/DH or MDA (excluding circling minimums) down to 100 feet
above TDZE using EFVS in lieu of natural vision
• From 100 feet above TDZE to landing, natural vision required
• Same language as §91.175 (l)

New | 14CFR §91.176 (a)
• Allows for descent below DA/DH down to touchdown and rollout
using EFVS in lieu of natural vision (No less than 1000 feet RVR)

EVS-To-Land | EFVS Credit
“NEW” | 91.176(a) – Visual Cues and Touchdown Zone
• From DA/DH to 100’ above TDZE: “Any approach light system
or both runway threshold and touchdown zone” visible using
EFVS
• From 100’ to touchdown and rollout, one of the following must
be distinctly visible/identifiable using EFVS: runway
threshold/threshold lights, touchdown zone surface/lights or
markings of touchdown zone

EFVS Performance
What is Visual Advantage ?
The measured
difference between
the distance required
to see an object with
natural vision and
the distance required
to see that object
with the enhanced
vision provided by
an installed EFVS
sensor.
