I was wondering if there are any IT "boffins" who might know how to do this...

A client operates a cargo flight (CAO) to a remote airport/station and we supervise the loading and unloading of the aircraft among other things. We provide a loading supervisor/ turnaround coordinator to meet the aircraft on arrival, send the crew to a hotel and assist the loadmaster to unload and load the aircraft whilst it is on the ground. The aircraft operates irregularly and flight plans and loading and unloading schedules regularly change. All flight plans and logistics are developed at a central HQ and our supervisor remains planeside liaising with them via email. He has to arrange crew transportation, hotels, ground handling assistance, refuelling, cargo breakdowns, catering deliveries, strap/net/pallet reconcilations etc... As the airport in question is primitive and the majority of airport service providers hopeless, he has quite a task on his hands and the HQ (on another continent) sit there pulling their hair out wondering what is going on and desperately wanting an update.... sometimes they think everyone must be dead!

I regularly remind the loading supervisor to send an update every 30 minutes to the HQ. Even if there is no news he should just send an update to say no news. So for instance, if he is just waiting for the fuellers he could update and say "just waiting for fuel, fuellers say they will come in 10 mins..." Then 30 mins later he would say "fuellers still not at aircraft but they promise that fuel truck will be planeside in next 15 mins. Will confirm when it arrives..." Unfortunately, he does not manage to send his updates every 30 mins which causes unnecessary stress...

Is it possible to arrange it that if you have not sent an email to a certain email address within a predefined timeframe you receive a notification to send another email?

I doubt anyone has thought of this but I was wondering???
