SCOPE • The problem • The past: previous regulation • The present: current regulation • The RAF’s approach to policy making • The future: recommended regulation
The problem % Air accident rates with age (1) Broach et al, FAA, 2003 (2) Melzer et al, Age UK, 2015 Comorbidity % (2) Melzer et al, Age UK, 2015 (2) Melzer et al, Age UK, 2015

RAF AvMed policy development •SCAMS policy development •AMSSG policy endorsement •AP1269A policy publication
RAF approach to policy making Consideration to employment law •European Employment Directive 2000/78/EC •UK Equality Act 2010 •Legitimate age-based practices must be objectively justified •Ensuring combat effectiveness is deemed legitimate Other considerations •Civilian standards are used as a baseline: •Consideration of other Nations Air Forces’ policies •The One Percent Rule is used cautiously •1 st , 2 nd and 3 rd party risk
Civilian approach to acceptable risk Acceptable accident fatality rate set at •1 in 10 7 flying hour •1 in 10 9 flying hours due to medical incapacitation For multi-pilot ops: 1% per annum •10% critical flight •1% unsuccessful handover For single pilot ops: 0.001% per annum •Whole flight is critical •No opportunity to hand over control •Not achievable other than in young adults

My thoughts The risk defining disease is cardiovascular disease (5) Wigglesworth, Joint •Sudden incapacitation Epeliepsy Council of the UK and Ireland, 2011 •Hidden until it happens •Risk easily reaches the 1% threshold in the older pilot Other risks are sub-threshold or visible •Epilepsy doesn’t reach 1% per annum •Visual acuity and hearing are easily tested •Cognitive decline can be spotted at medicals / sim checks •Reduced mobility can be assessed functionally
Final DRAFT recommendations Age Test Notes Annually Medical (plus ECH as per schedule) As per current practice. 50 an annually QRISK2 10% over 10 year threshold for further thereafter investigation. 60 and 5-yearly CT angiogram Scoring system to be agreed. thereafter 60 and 2-yearly Exercise ECG, echocardiogram and thereafter ambulatory ECG
