Keep it SIMPLE.

I made us a one page excel schedule that lists staff (only 5 of us) and all the training events we will cover, when they were done, when due, and notes on who the vendor is/contact etc.

Simply called "Training Schedule" with these events:

FAA Medical
FSI/CAE Recurrent
Intl Ops Procedures
CRM
BRNAV/PRNAV/MNPS
HAZMAT
AC Emergency EVAC/Equipment
CPR/AED/Forst Aid
FACTS
Winter Ops
Summer Ops
GOM Review (or FOM)
Company/Hangar Emergency Drill
SMS annual Training

We use vendors for everything except a few items which get discussed and recorded at quarterly meeting (we only meet at hangar/office once a quarter for approx 90mins, we aren't office types) Things like "Winter Ops" are a quick review of deice/runway limitations etc. Simple.

We are Stage I ISBAO and auditor liked it a lot. Very quick and easy to see whats due as I will highlight that persons event in RED. They are mainly looking for a way that you track the events, accountability. A simple calendar and notes saved from quarterly meetings was easiest for us.

When asked about "new Hires" I said we dont anticipate any right away and will add a list of items when we do. We will likely be interviewing/adding a pilot soon so I anticipate adding "airplane initial" and a few intro items like Ops Manual review (heres a copy lol) to the list.

We keep/update/distribute this sheet on iPads.

It seems overwhelming at first, but you are likely doing everything you need to be doing...now just document it.

GOOD LUCK!
