Maximum holding speed for a civil turboprop aircraft?

[BodhiWes]

I am studying for the SARON (ATPL exam) and studying with the Aerocourse study resources and am having trouble with a questions regarding max holding speeds. Here is the questions;

The maximum holding speed for a civil turboprop aircraft at an assigned altitude of 7,000 ft ASL is:

a) 175 KIAS
b) 200 KIAS
c) 230 KIAS
d) 265 KIAS

The answer is c) in the book and correlates with 10.7 Speed Limitations in the AIM. But I have read it numerous times that Propeller Aircraft (Including Turboprop) Max holding speed at MHA to 30,000 ft is 175 KT IAS making a) the correct answer.

If I could get clarity on this, that'd be great. Thank you.

The holding speeds were recently revised by TC as per current AIM.

You are probably remembering the old rules which have now changed; any source that is more than about 2 years old will be based upon the old rules.

I believe what you're referring to is the old rules (attached) which were updated (in 2018 if I recall correctly) to what you're seeing in the AIM now. As usual, after a rule gets updated a lot of the reference material lags behind.

Right on. Thank you very much for the clarification.

Has this changed again?
I am looking at the current AIM (March 24th - October 6th 2022) and section 10.7 "Speed Limitations" shows the speeds based on altitudes.

At or Below 6 000 ft - 200 kts
Above 6000ft up to and including 14000 ft - 230
Above 14000 ft - 265

I don't see anything regarding turbojet or turboprop.

Also need clarification as I have my IATRA next week.

Thanks everyone.

Holding speeds are now based on altitude and not engine type

ok makes sense, thanks for confirming.
