This is not a flight examination it is a rental check out. Your job is to teach and teaching requires communication.
We’re not trying to create astronauts here.
1. May I see your logbook, medical and pilot certificate please?
2. Have you flown out of this area before?
Yes/No, cover local procedures or any changes.
3. Have you flown this make/model before?
Even with the homely C172 there are 20(?)-ish variations over the years. Some with minor, some with major differences.
Cover the differences.
4. The following maneuvers are what we require for a rental checkout. Standards are Private pilot practical test standards. Do you have any questions about how to execute any of these maneuvers? We can practice these maneuvers to proficiency if required.
5. This is the checklist that we use, it may be different from what you are used to because of the make/model/variation that we fly.
6. At the end of this flight we both need to feel comfortable you renting this airplane.
Do you have any questions?
Something like the above.
Complaining on an anonymous forum though is like leaving a bad review online of a business and not giving them the opportunity to correct the perceived issues.
