Wearing fireproof clothing will do you sod-all good when the cockpit fills with fumes, which will prob99 happen long before you get any flames. Are you going to wear a hood with an air bottle on the back of it as well?
IO540, no need to be patronising or sarcastic. Nomex isn't fireproof, it's flame resistant; it doesn't melt in a flash fire. Nylon and other synthetics can do so.
No, I've never felt the need to wear a smoke hood. I would carry out the fumes in the cockpit drill, jettison my cockpit door if necessary then land after a sideslip descent, asap. In any case, a smoke hood is no good if you cannot see out of it, blinded by smoke.
My employer provides polyester based uniform items. I usually wear my own, more expensive woollen based trousers instead, and a pure wool jumper of my own choice over my shirt.
One further thing I would feel more comfortable with is a protective helmet with a double visor. Unfortunately it would possibly make the passengers feel insecure, so we don't wear them in our specific line of work.
These are personal choices based on risk assessment of the environment I fly in and referring back to previous accident reports and from my own personal experiences.
