OK I suppose I'd best chip in as everyones being so honest
I used to be in the UAS and at that time we were given a preliminary IF grade (after a suitable amount of training).
This entitled us to penetrate (ooh-er missus) 2000' of cloud in a straight line under a RAS. We WEREN'T allowed to turn and if we weren't VMC(ish) after 2000' of crud we had to descend and play underneath.
having got my new endorsement in my logbook I went off looking for a bit of cloud to fly through (as you do) and called up the local radar for a bit of a service and off I went.
All was going swimmingly, best instrument scan an aviator ever did etc., until i got the call "UA**** avoiding action turn left heading blah" "err **** radar I'm not permitted to turn, PIFG rating" "UA**** AVOIDING ACTION TURN LEFT HEADING BLAH"
oh well methinks it sounds kind of important to them so I'd better do what they say.
start the turn, OK bit nervous but I can cope, watch the scan AI, Airspeed, AI, Turn Needle, AI, Airspeed, A.. er Airspeed shouldnt that be 85knots whats it doing at 75 knots how did that happen err turn needle why is that going past 45degrees oh FU*K 70 knots ok stick right and forward. now what heading did he say oh fu*k now i'm descending.
You get the picture but this continued for about another minute until I sorted myself out and got above the clouds.
funny old thing but I scared the sh!t out of myself over something pretty minor and I panicked which is not the best thing to do so I suppose the moral of the story is know your own limits and just coz you've got a bit of paper that says you can do something it doesn't mean you have to.
