I recently took the decision to take off marginally (about 50lbs) overweight in a 172 on the basis that the 2.5 hour flight would leave me well within the W&B when landing at the planned time (luckily I didn't have an emergency or unplanned early landing so that panned out OK).
This left me wondering if insurance wise, had push come to shove, would the insurance be void for the entire flight or just the period of the flight when the aircraft was overweight.
It also left me wondering just how forgiving the limits are - I had a couple of female passengers who were quite uncomfortable about giving their weight & a chap who didn't know his, so short of installing scales in the club the accuracy of self report W&B info must be subject to scepticism.
