some exceptions: As such, we have concluded that the same aircraft
excluded from the transponder requirement are excluded from the ADS-B Out equipage.
Accordingly, an aircraft that subsequently has been installed with batteries or an electric
starter would not be required to equip for ADS-B Out. The FAA may consider a technical
amendment in the future to remove any confusion due to the discrepancy between the
language in§ 91.215(a)(5) and§ 91.225(e).
I agree. I would say the only reason providers are not cost estimating is because they don't need to in order to get business.
For automotive I'm typically getting a problem diagnosed first, then after diagnosis, I'm agreeing to a price for a fix. This is the norm for that industry.
For a walk in appointment for a rash, I'm agreeing to a fixed visit fee, PLUS signing that I agree to pay any charges my insurance does not agree to pay. The true costs can (and should) be computed by the provider, so the only true unknown in that equation is what Insurance will cover. THEN the provider (wanting to cover their bases) is putting that risk of not getting paid by insurance, back onto the patient.
I like to think we're 1 killer app away from a shift in consumer behavior here to change the expectations
