Well now there’s a loaded suggestion. Need a lot of extra information Framer..what’s the weather for a starter..what time of day? As a multiple vector runway on a lovely day with nothing in TAFs or TTFs to hold extra fuel for, outside of the times when extra holding fuel is required (or even if the holding fuel was required to be used) you wouldn’t get too much change out of 45 minutes (especially if you’re talking holding fuel on 2 engines at 1500’ or whatever the CAOs say these days)
Depends on your company requirements of course but the accounting department doesn’t like you burning fuel to carry fuel on a domestic flight either..that’s for sure
