Narrative: Taking off from okc we briefed the dep hdg 175 on the TRUPR 1 during our takeoff briefing. Before takeoff I pulled up the dep text just to make sure we were doing the correct hdg and I misread hdg 200. Knowing I was correct that's what we did. After turning and then switching to dep we realized I was wrong. No other deviations occurred. When looking at sids make sure you are looking at the correct airport when there are numerous airports with like runways.


Second narrative: While departing from OKC on the TRUPR1 departure; the captain (pilot monitoring) was performing his duties while following our previously briefed takeoff and departure; which included flying runway heading on the RNAV departure. As the captain checked in with departure; he swung the heading bug to a heading of 200 and informed ATC that we were climbing (stating leaving altitude climbing for published altitude) and in the turn to 200. I told him the departure was fly runway heading and went to correct; but by this time ATC had acknowledged our position and issued new instructions. She also inquired as to whether the heading of 200 was assigned in our clearance; to which the captain replied it was. As we turned to a new heading assigned by ATC; I insisted that there was a mistake and as we reviewed the chart he realized that just prior to takeoff; he had enlarged the plate on his ipad and had read only the textual content of the departure for a different airport sharing the TRUPR1. Unfortunately; this airport had a similar runway configuration and he reacted and contacted ATC so quickly; believing that we were doing what we should; that by the time the error was realized we had already checked in and been issued new ATC instructions.Clear communication: we had briefed the departure; but when the captain saw what he thought was a problem with the brief we should have discussed it rather than one pilot taking unilateral action Follow CFM: PM should tend to his duties and not assume control of the flight control panel while the PF has the aircraft. In both of these cases the captain; while mistaken; believed he was doing the proper procedure for the departure.Use Proper phraseology: we were cleared to 'climb via' and on initial contact ATC was informed of our present altitude; our assigned altitude and our heading; rather than stating 'climbing via'.TRUPR1: this departure shares multiple airports on the same textual description. One of these airports has a similar runway configuration to OKC. Should a pilot take a quick glance on a takeoff (as what happened in this case) they may fly the improper departure procedure. Pilots should use caution when flying such a departure. Additionally; texts sharing multiple airports on the same departure can be its self confusing. Clear and specific departures should be considered for individual airports. Clarification on climb/descend via: it seems that such clearances might be better suited only in busy airspace with high traffic volume. Being issued a climb via clearance on a vectored (albeit RNAV) departure may be better understood with further clarification as to the intent of the clearance.


Synopsis: EMB-145 flight crew reports a track deviation departing OKC Runway 17R; when the Captain confuses the initial climb instructions for Wiley Post with those for OKC. An iPad was in use and had been zoomed in to Runways 17L/R for Wiley Post.
