This is what training is for, even as a low hour start thinking about the IRR
To put it in context, soon after getting my IRR I flew a real live ILS approach in real live IMC. No instructor beside me, no-one else in the plane, no chance of a sneaky peak outside the hood. No chance of a second chance and no reset button.
Breaking out of cloud to find the runway where it should be was one of life's Eureka moments. But I hadn't realised how much it had drained me until I tried getting out of the cockpit, my legs had turned to jelly and my shirt was sopping wet.
So don't underestimate how taxing flying on instruments can be, especially real life when a mistake can be your last.
