An IR will help on that last 10%, but he needs to get a more capable
plane
if he really needs to get somewhere at a certain time, 100% of the time.

You mean like an Airbus or Boeing?

Point taken.

Even then, on my last commercial flight I ended up stuck in Denver overnight
due to the crew being stuck in Wyoming due to weather...

There is no 100% reliable form of transportation.
