Narrative: Bottom Line: Did not see general speed restriction on JEPPESEN STAR. Details: Descending on JKNOXX.HHOOD4 STAR into PDX using VNAV profile in FMC. First speed restriction in FMC was 270 kt. at BAYYR. There is no speed restriction listed directly next to MYTOE and JKNOX; the first two points on the STAR. In the vicinity of MYTOE; the Center Controller asked our speed. Pilot not Flying; CA (Captain); answers with 300 kts. Center Controller asks us to fly the 'published' speeds. The CA and I rechecked the star and saw the 270 kt. restriction at BAYYR as the first speed restriction. The CA responds that we're slowing to 270 by BAYYR. Center Controller instructs us to go ahead and slow to 250. Once on deck; the CA and I reviewed the STAR and found a note written in the top right corner that says for turbojets to descend via Mach number until intercepting 280 kt.; maintain 280 kts. until slowed by the STAR. We did not see this note real time in the aircraft and were about 20 kts. fast for a portion of the STAR between JKNOX and MYTOE. I was responsible for complying with and should have seen the note and will certainly double check for them in the future. However; I believe the following are contributing factors of why the note was missed by both aircrew. On the vast majority of STARs; speed restrictions are almost always listed directly next to the points they apply to. Thus; we are not conditioned to necessarily search for speed restrictions elsewhere. The speed restriction at FLAVR on the ZIGGY7 STAR into ONT is a good example of a speed restriction written prominently directly next to its respective way point. The general speed restriction on the HOOD4 STAR is written in magenta against a black background. While it was daytime; the Jeppesen FD Pro application was being run in night mode to conserve battery for the 6+ hours of scheduled block time that day. Post flight; when I switched Jeppesen FD Pro to day mode; the note was more prominent/easy to see with a white background. The speed restrictions that are listed directly next to the points also show up in the FMC when the STAR is loaded. Every speed restriction that was listed on the STAR directly next to the way point showed up in the FMC; creating an incorrect expectation bias that if a speed was not listed by the FMC and not listed directly next to the way point on the STAR depiction; then there was no speed restriction for that point. Suggestions: Ensure general speed restrictions are depicted more prominently on STARs in both day and night modes of the JEPPESEN FD Pro application. List general speed restrictions next to the 'Routing' section of the STAR so they'll be easier/more likely to be seen. For points such as MYTOE and JKNOX on their HHOOD4 STAR that have a 'general' speed restriction; place an asterisk next to the point; as well as next to the general speed restriction. This asterisk would cue aircrew to important information located elsewhere on the STAR depiction to locate and read. Insert an 'Arrival' page into the Airport Briefing Guide for PDX and insert a section describing this general speed restriction on the HHOOD4 STAR.




Synopsis: B767 First Officer reported an airspeed deviation during arrival on a STAR that contained vague charting.
