Firstly, I have been put in my place by my good mate Chilli and rightly so!

It entirely depends on your personal confidence in dealing with the pertaining situation, it's all very well being wise after the event but if you feel you need to get on the ground ASAP, declare a MAYDAY and we'll do the best we can for you.
There is absolubtly no shame whatsoever in admitting that you need help, , we will decide the level of emergency assistance required via well planned procedures and we can always upgrade or downgrade this as required.
That aside, given that a minor problem occassionaly develops into a more serious situation, fore armed is fore warned.
