Risk reduction/mitigation assessment factors.

Company culture
Corporate/company management
 Places safety before schedule20
 CEO signs off on flight operations manual20
 Maintains a centralized safety function20
 Fosters reporting of all CFIT incidents without threat of discipline20
 Fosters communication of hazards to others15
 Requires standards for IFR currency and CRM training15
 Places no negative connotation on a diversion or missed approach20
Flight standards
Specific procedures are written for
 Reviewing approach or departure procedures charts10
 Reviewing significant terrain along intended approach or departure course20
 Maximizing the use of ATC radar monitoring10
 Ensuring pilot(s) understand that ATC is using radar or radar coverage exists10
 Altitude changes10
 Ensuring checklist is complete before initiation of approach10
 Abbreviated checklist for missed approach10
 Briefing and observing MSA circles on approach charts as part of plate review10
 Checking crossing altitudes at IAF positions10
 Checking crossing altitudes at FAF and glideslope centering10
 Independent verification by PNF of minimum altitude during stepdown DME (VOR/DME or LOC/DME) approach20
 Requiring approach/departure procedure charts with terrain in color, shaded contour formats20
 Radio-altitude setting and light-aural (below MDA) for backup on approach10
 Independent charts for both pilots, with adequate lighting and holders10
 Use of 500-foot altitude call and other enhanced procedures for NPA10
 Ensuring a sterile (free from distraction) cockpit, especially during IMC/night approach or departure10
 Crew rest, duty times, and other considerations especially for multiple-time-zone operations20
 Periodic third-party or independent audit of procedures10
 Route and familiarization checks for new pilots
 Domestic10
 International20
 Airport familiarization aids, such as audiovisual aids10
 First officer to fly night or IMC approaches and the captain to monitor the approach20
 Jump-seat pilot (or engineer or mechanic) to help monitor terrain clearance and the approach in IMC or night conditions20
 Insisting that you fly the way that you train25
Hazard awareness and training
 Your company reviews training with the training department or training contractor10
 Your company’s pilots are reviewed annually about the following 
 Flight standards operating procedures
20
 Reasons for and examples of how the procedures can detect a CFIT “trap”30
 Recent and past CFIT incidents/accidents50
 Audiovisual aids to illustrate CFIT traps50
 Minimum altitude definitions for MORA, MOCA, MSA, MEA, and so forth15
 You have a trained flight safety officer who rides the jump seat occasionally25
 You have flight safety periodicals that describe and analyze CFIT incidents10
 You have an incident/exceedance review and reporting program20
 Your organization investigates every instance in which minimum terrain clearance has been compromised20
 You annually practice recoveries with GPWS in the simulator40
 You train the way that you fly25
Aircraft equipment
Aircraft includes
 Radio altimeter with cockpit display of full 2,500-foot range—captain only20
 Radio altimeter with cockpit display of full 2,500-foot range—copilot10
 First-generation GPWS20
 Second-generation GPWS or better30
 GPWS with all approved modifications, data tables, and service bulletins to reduce false warnings10
 Navigation display and FMS10
 Limited number of automated altitude callouts10
 Radio-altitude automated callouts for nonprecision approach (not heard on ILS approach) and procedure10
 Preselected radio altitudes to provide automated callouts that would not be heard during normal nonprecision approach10
 Barometric altitudes and radio altitudes and radio altitudes to give automated “decision” or “minimums” callout10
 An automated excessive “bank angle” callout10
 Autoflight/vertical speed model10
 Autoflight/vertical speed mode with no GPWS20
 GPS or other long-range navigation equipment to supplement NDB-only approach15
 Terrain-navigation display20
 Ground-mapping radar10
