In a previous article, Jon Kraus said:
1. Make sure that I have had the vacuum indicator "in the green" for
several minutes before departing to ensure that the gyros are spooled up.

2. Have the approach for returning to the airport loaded or in standby
just in case you need to return quickly. I did not do this and it added
needless stress loading everything.

It couldn't hurt to have a mechanic look at your vacuum system.
