Or it becomes binding even if your plane has no AFM. I have a half a dozen flight supplements (IFR GPS, Autopilot, tip tanks, etc...) for a non-existant flight manual.
Similar here. No AFM, just a POH that’s been “Amended” by the Robertson STC, and then a pile of mini GPS books now that have to also remain aboard.
They’re all in a very heavy duty ziplock in the side pocket for the legalities and the once in a decade need to look something up in the airplane. I use digital copies and other paper copies to actually look things up. Or if someone else wants to look something up about the airplane when we’re away from home they can go get the baggie and read and put it all back.
Don’t put it all back, you die.
I know that baggie has all the legal stuff.
Keeps them clean and non-greasy after spending $35 for a new “official” Cessna POH and feeling lucky it wasn’t an AFM ($$$$$$$!) that had slowly disintegrated into crumbly bits in a previous baggie.
Recently for the CFI ride I decided using two different documents for official checklists was utterly stupid and re-wrote a checklist with all legally required items from both the Cessna and Robertson POH addendum and put it in little plastic page covers with rings.
Much nicer than my generic 182 single card version from a well known vendor of those things with different speeds written over it in Sharpie.
And of course now I’m all anal about it. I’m on Revision 6 and it needs a Revision 7. I knew that would happen.
I got the takeoff briefing (not in ether official checklist) somehow cut and pasted right BEFORE “Flight Controls...” LOL. Obviously a stupid place for it.
The interesting things to note about the Robertson STC POH addendum were:
- “Normal Takeoff” was completely removed. Found that fascinating since the airplane will happily do one. I put the Cessna one in but the Robertson clearly says to replace all of that with theirs and they didn’t include “Normal”. Just short and soft. LOL. I guess they wanted you showing off your STOL kit at every takeoff.
- The performance chart for landings isn’t temperature compensated but the takeoff one is. It’s clearly an omission in the notes below the table. Someone just left out a line, and FAA and everyone appears to have missed it.
Yay 1970s STCs. High quality stuff, baby. (Ours is 1977 dated.)
Then Robertson went away and there’s nobody around to issue an update. Some company owns the STC but they DGAF about it. They just wanted it to sell overpriced repair parts.
But it’s nice to have an “officially and legally combined documents, unofficial checklist” for the airplane now.
I suppose for Revision 7 I should also double check that the GPS check items I included “unofficially” don’t have “official” wording in the GPS manual that could/should be used instead of my words. The GPS itself walks you through the test cycle and then after that it’s “no yellow or red annunciations” realistically.
