Over the last 6 years, 23 of 82 turboprop major accidents has been a CFIT– that’s 28%, or more than 1 of every 4 !
Upset Aircraft Loss of Control Unusual Attitudes Lack of Control Upset Aircraft Stall Extended Envelope Advanced Maneuvering
Upset Aircraft Accident An upset accident is an accident in which an aircraft is upset and unintentionally flown into a position from which the crew is unable to recover due to either aircrew, aircraft, environmental, or a combination of these factors.
Over 25 degrees nose up • Over 10 degrees nose down • Greater than 45 degrees bank • Airspeed inappropriate for conditions
Aircraft Upset Major Accidents Commercial Jets 1 January 2012 through 31 December 2012 None in 2012
Aircraft Upset Major Accidents Commercial Jets 1999 through 2012 6 Number of Accidents 4
Upset Aircraft • No good visual references • * IMC • * Night • * Over Water or lightless/featureless land - Distraction involved - Initial movement imperceptible (2 degrees/sec) - Initial correction often in wrong direction - One of crew has good or better SA – but wait too long to correct the situation - The pilot who got into the upset situation is theleast likely one to be able to recover from it
Stalls 1. #1 Factor: Angle of Attack 2. Low Speed warning systems ? 3. For airspeed issues --Pitch and Power 4. Modern aircraft know their AOA Why doesn’t the crew ?

Other Challenges - Functional Check Flights - Unreliable Airspeed
Functional Check Flights - Symposium February 2011 - Vancouver - EASA Rulemaking on FCF (NPA published) • FCF Steering Team • * Boeing • * Airbus * Bombardier * Embraer * Gulfstream - FCF Compendium
Flight Safety Foundation Functional Check Flight Compendium • Introduction • “Be Prepared” paper • FCF Guidelines Document - Preparation - Ground Phase - Flight Phase (25 Modules: e.g. Auto Pilot, Air Conditioning, APU) • FCF Symposium Material
Unreliable Airspeed The Issue Historical and recent accidents and incidents have highlighted the increased risk associated with unreliable airspeed (URA) events • Industry Steering Group Formed Created URA Philosophy and Guidelines
URA Philosophy • The keys to successfully dealing with a URA event are recognition, procedures, and training • The aircrew’s recognition of and initial reaction to a URA event are critical • Manufacturers should attempt to ensure unreliable airspeed events are clearly identifiable to aircrews • The most important function of the aircrew during an in- flight URA event is to maintain control over the aircraft’s flight trajectory and energy situation by selection of attitude and power settings so that the aircrafts flight parameters remain within normal limits
URA Philosophy - Crews should be aware of the instruments and critical systems that are not affected by a URA event (e.g. attitude displays, engines) - Procedures and training for URA events should include the effect of a URA event on other aircraft systems, and potential alerts/warnings and indication system inaccuracies that could be expected - Crew coordination and communication are important elements in successfully addressing a URA event
URA Guidelines - URA procedures should provide information on attitude and power settings that enable crews to maintain the aircrafts flight parameters within normal limits during in-flight unreliable airspeed events for all phases of flight - URA procedures should address the availability and use of independent alternate sources of airspeed information (e.g. GPS, inertial, angle of attack, etc.) - URA procedures should include memory items for critical immediate action steps - Training programs addressing URA should exist at beginning (ab initio/MPL), initial, and recurrent levels - URA training should include both simulator and academic phases
Aviation Safety 2012 • Record year for commercial jets • Record year for commercial turboprops • Average year for business jets • CFIT continues to be a challenge – and it is making a strong comeback as the leading killer • There are many challenges out there, and FSF is addressing many of them: * Runway Excursions • * Upset Aircraft • * Functional Check Flights * Unreliable Airspeed
Some Things to Think About • Upset Aircraft not a major issue in business aviation • CFIT not a major issue in business aviation • ALA is a major issue in business aviation • - Over 75 % of accidents over last 4 years • - Majority of those were runway excursions Data and Risk Management
