Deviation from Established Procedures

From SKYbrary Wiki


Whilst safety has been much enhanced over the past twenty years or so by more and better procedures/checklists etc, the statement currently in the article that there is always an appropriate procedure/checklist for every situation is not true - and cannot be expected to be. There are still abnormal/emergency situations which occasionally confront pilots which require them to take decisions based on the evidence before them, their training and the available procedures insofar as the latter are relevant. It would not be possible (or sensible) to try and develop procedures for every conceivable eventuality - unless the pilotless aircraft is coming to civil aviation! There is still a need for 'airmanship' which I notice does not get an entry in Skybrary yet....or 'good maintenance practice' for our engineering colleagues. I'm not sure what the equivalent ATM term or phrase is(?).

By the way, 'inappropriate pilot action' extends a lot further than 'Loss of Control' in it's safety-related outcomes!--Joe.scott 12:46, 19 February 2008 (CET)

there can never be prescription for every scenario...

As a pilot, I agree with the earlier comment. We have lots of very good SOPs and some well-tested QRHs but in my experience, it not the case that there are procedures for everything and it is still sometimes necessary for pilots to resort to airmanship to resolve an abnormal situation effectively in the case that there is no applicable procedure. In my airline, we do not need any more procedures - the ones we have cover everyday operations, emergencies and the more involved abnormal procedures very well, but they will never , and should never, cover everything. Most of us would have a problem remembering many more.

We have seen some cases recently where pilots have managed to escalate very minor technical occurrences such as a single instrument failure by trying to find an applicable procedure, and when one cannot be found, using the nearest similar one with unintended effects.--Chris.stewart 13:33, 19 February 2008 (CET)

Editorial comment

Quite correct. Article renamed, redrafted and link to Loss of Control removed.--Ian.Wigmore 13:18, 20 February 2008 (CET)
