There is no reason from either an operational or safety standpoint the gear cannot be extended before the flaps on any model of the 737. In fact, there are distinct advantages to deploying the landing gear before the flaps. In locations like LAX the ATC system tends to frequently change the speeds of the aircraft to the point that the crew might find themselves faster than they would normally be on their arrival. The extension of the gear acts as a speed brake to slow the aircraft to a normal flap extension speed. One does not normally think of landing gear as an aerodynamic control on the aircraft, but at speeds higher than allowable flap extension speeds it makes an EXCELLENT speed brake. In fact we refer to them as "Goodyear Speedbrakes" in our lighter moments. There is nothing abnormal or unsafe about what you experienced. Undoubtedly, it was simply the flight deck crew using all of the methodologies available to them to operate the aircraft safely and efficiently. Don't be concerned. I'm glad you asked though. Most of what fear is all about is lack of knowledge. If you have any other questions I'd be happy to answer them. >Is it unusual to not extend the wing flaps until after the landing gear >has been deployed? >When I was coming into LAX the other day on a 737, we were cleared to >land (I was listening on the headphones to ATC), when the gear was >deployed....and then the flap were extended.
