QUESTION: Where is this?
(what sort of place would have a road called ‘Airmanship Road’ ?
4
Recognise it yet?
5
ANSWER: …which is the home of: RAF College Cranwell
Central Flying School

What is AIRMANSHIP ? Airmanship is skill and knowledge applied to aerial navigation, similar to seamanship in maritime navigation. Airmanship covers a broad range of desirable behaviours and abilities in an aviator. It is not simply a measure of skill or technique, but also a measure of a pilot’s awareness of the aircraft, the environment in which it operates, and of his own capabilities Wikipedia

What is AIRMANSHIP ? …some other suggested definitions AIRMANSHIP is: The (technical and non technical) knowledge, skills and attitudes aircrew employ to operate an aircraft effectively, efficiently and safely. LMQ (‘Crew Resource Management’ trainers) (Author of ‘Airmanship’ – Carey Edwards is a director)

Airmanship is acquired through experience and knowledge
What is AIRMANSHIP ? …some other suggested definitions Airmanship is the application of flying knowledge, skill and experience which fosters safe and efficient flying operations. Airmanship is acquired through experience and knowledge Transport Canada

What is AIRMANSHIP ? …some other suggested definitions
‘…true airmanship is the ‘total package’ requiring both physical and cognitive skills and an appropriate attitude. These three essential ingredients can be labelled as judgement, control and discipline. Airmen need a balance of these to excel at their job. ‘ Human Factors Department at Advanced Technology Centre Good airmanship is that indefinable something, perhaps just a state of mind, that separates the superior airman/airwoman from the average. It is not particularly a measure of skill or technique, nor is it just common sense. Rather, it is a measure of a person's awareness of the aircraft and its flight environment and of her/his own capabilities and behavioural characteristics, combined with good judgement, wise decision making, attention to detail and a high sense of self-discipline.

Airmanship = safe flying = avoiding getting into a high risk situation
What is AIRMANSHIP ? …some other suggested definitions Airmanship = safe flying = avoiding getting into a high risk situation AND recovering OK when something bad does happen Chas Cowley

Why do we need safer gliding?
BGA ‘Safer Gliding’ program Why do we need safer gliding? Fewer tragedies Avoid over regulation Retain insurance Fewer repetitions of common accidents does not mean avoiding normal risks or taking the fun out of gliding 13
14
Numbers of accidents in 2008
fatal injury serious injury minor Injury crash minor/no damage all 2008 6 12 51 69 120 2007 4 9 16 53 73 126 2006 3 7 8 54 91 145 weighted average 2.7 4.4 11 39 108 14
15
Serious injury accidents in 2008
Undershoot, instructing Field landing, unlandable terrain, mutual Field landing, overshooting, cartwheel Spin from final glide Undershot, hit tree Lost locally, landed through barbed wire 15
16
Pattern of crashes in 2008 no collision, fewer winch, fewer stall/spin
16 field landing; 19 field landing including the 3 in stall/spin 12 landing on home airfield; this is double the average rate otherwise, a repeat of the average pattern 16
17
2008 was the first year since 1985 with no fatal accidents

19
Winch accidents in 2008 no fatal or serious injury accidents 4 crashes
Two no-injury accidents/incidents could have been fatal glider climbed to a stall after hitting the ground followed by back release of the cable pilot slid up the seat and inadvertently pulled the stick back to cause a stall So no grounds for complacency 19
20
Winch accidents 2006-2008 (the 3 years of the BGA safe winch launch campaign)
21
Winch accident summary 2006-8
one fatal accident, cartwheel one serious injury accident, cartwheel 10 crashes 35 accidents and incidents 21
22
Winch fatal and serious injury accident rates from 1974-1998 and from 1999-2005 were identical
22
23
23
24
Winch fatal and serious injury accident rates from 2006-2008 were lower
24
25
25
26
Winch summary 2 fatal/serious injury accidents instead of the 7 expected at the rate for no fatal/serious injury accidents from uncontrolled flight 10 crashes instead of 21 wing drop accidents continue instructing accidents continue lesser accidents continue 26
27
What does this data mean?
It suggests: real progress in educating inexperienced pilots on how to winch launch safely no success in persuading experienced pilots to release if they cannot keep the wings level no success in reducing instructing accidents 27
28
Conclusions for 2008 zero fatal accidents is only significant if it repeats in 2009 except for winch launches, accidents in 2008 reflect the way we do things fewer accidents requires changes in the way we do things 28

Currency: ….flying is NOT like riding a bike
Just because it’s legal doesn’t mean it’s safe (3 landings in the last 90 days???) Assessing proficiency? Be conservative – ‘trust no one’ Patterns of physical skill loss – fastest in areas of finesse Mental proficiency – lost faster than physical skills ‘Chair flying’ – a good idea to rehearse – sitting and thinking… Proficiency Skill Discipline Tony Kern’s airmanship model

? Risk RISK = Potential Consequence x Probability
of a HAZARD of an incident ?
41
Consequence (eg No. of deaths)
EXAMPLE of the risk calculation ALARP = risk ‘As Low As Reasonably Practicable’ - Lord Justice Asquith 1949 UK Health & Safety Exec - Risk management: ALARP Suite of Guidance 1 in a thousand Intolerable Probability 1 in a million ALARP ‘Tolerable’ 1 in 100 million 1 10 100 Consequence (eg No. of deaths)

DAL 39 10 Dec 1998; 10:32

RUNWAY 24
47
OPERATIONAL CONDITIONS
On the day of the incident, low visibility and a low cloudbase made visual control from the tower impossible. Radar had to be used to direct air and ground traffic A few minutes earlier, Air Traffic Control had changed runway use configuration from two landing runways (19R and 01R) and one departure runway (09) to the so-called outbound mode with one landing runway (19R) and two departure runways (09 and 24)
49
The DAL 39 event scenario Pilots see 747 and abort take-off
Poor ergonomics of radar screens and runway stopbar controls Pilots see 747 and abort take-off Routine violation of tow procedures Complex airport structure Tower combining training and operations during difficult periods Controller gives clearance without assurance of tow position
50
PROBABLE CAUSE The following causal factors were identified:
Low visibility weather conditions which prevented Air Traffic Control to visually identify vehicles on the ground Inadequate information during the radio communications between tow (yellow van) and Tower Misinterpretation of position and movement of the tow Take-off clearance without positive confirmation that the runway was unobstructed Insufficient teamwork and supervision.
51
KEY LEARNINGS The incident was triggered by a momentary loss of ‘Situation Awareness’ But there were several underlying ‘latent failures’ which colluded: - unclear tow procedures - poor communication between controllers - poor ergonomics of ground radar displays - poor ergonomics of runway access barrier controls - poor shift change procedure - insufficient supervision during training - pressure to deliver operational performance Lack of MINDFULNESS (airmanship…?)

55
Managing Risk identify hazards assess the risks
maintain good barriers: - to reduce the probability of things going wrong - and also to cope in case they do

Situational Awareness
What’s happening around you ? What does it mean to me ? What’s going to happen ? What ? So what ? Now what ?
58
Situational Awareness
Five ways to improve it Define roles Manage distractions Reduce workload Avoid complacency Test assumptions Intervene (…actually it’s six…)

Judgement Decision-making: Assess the situation Determine options
Rule-based decisions (STANDARD PROCEDURES) Knowledge-based decisions Aviate….Navigate…..Communicate ‘Threat & Error Management’ - a recent and very current technique that is used in airlines, the RAF etc…

Threat and Error Management
‘Defensive driving’ for pilots Asks - what are the likely hazards ? - What are likely errors I could make? …based on analysis / history Plan accordingly
