I was out at DCA yesterday and saw several mainline craft land on runway 33. I did not realize at 5,200 feet that Runway 33 was used for mainline traffic--its "only" 5,200 feet. I know it was very windy yesterday--I'm assuming that was the reason. Nonetheless, since most traffic was using Runway 1 (1600 feet longer) i'm curious as to what would cause some arrivals (non peak period) to be on 33. I'm not a pilot but I think i'd rather have the extra 1600.

There are a couple of reasons this might happen in DCA.
1. Even though Runway 1 is longer DCA often has strong crosswinds from the west, which would make 33 an easier landing even with the shorter length, since the headwind will reduce the landing distance needed as well as the groundspeed on final.
2. Because Runway 1 is also the primary departure runway, DCA may need a little more time to get departures out, or the plane thats cleared for takeoff on 1 takes his time on the runway, and in this case circling to 33 actually buys ATC more time with runway 1. I was in a CRJ jumpseat one time going into DCA and a Shuttle America E170 was cleared for takeoff as we were coming in to land on runway 1. The 170 took his time moving onto 1, so at about 500 ft AGL we requested and were granted a circle to land on 33 to buy time for the 170 and to prevent us from going missed completely. I have never seen a cockpit more busy in the next few seconds than I did that day.
3. The turnoff of runway 33 brings you right into the remote parking area that US uses for the RJ's and props. Air Wisconsin, PSA, and Piedmont will often take runway 33 to shorten the taxi time after landing with that in mind, much like 35 in PHL.

What about 4/22? I have seen maybe one takeoff on 4, if I remember it was a Dash 8 headed for EWR. It was able to make a right turn and go around Capitol to the east rather than having to loop around from the west as departures on 1 would require. Could CRJ or E Jet use this runway (4911') for flights headed to EWR/LGA/JFK/BOS?

It is possible, however it has to be a rather light load in order to do it (40 pax or less aprox). Truthfully, though 4 departures actually benefit flights to the south (I.E. Florida and the Coastal areas) more than flights to the northeast, because the right turn actually shaves about 10 minutes off a flight headed for the DAILY fix. Occasionally, you will see a steep right turn off of 1 for a DAILY departure since the normal left turn up the potomac requires a vector all the way around the north side of P 56 and then back down the east side of P 56. SWANN and PALEO departures (The ones up to NYC and BOS), actually don't gain anything with a right turn or a 4 departure, and 1 is still easier for them.
