Narrative:
I was showing a student how he could fly from W18 laurel suburban airport, to W92 sky bryce, west/O having to talk to any controllers, and do it legally and safely! However, we had contacted washington flight service for an update on WX about 5 mins earlier and we're told we were #5 in line for information. If we had received an immediate or more timely briefing we would have gone back to monitoring dulles departure control at an earlier time. This is what I encourage my students to do in any event, even if they don't want to talk to approach/departure. As we passed north of dulles iad, our left wing blocked our view of aircraft departing on runway's 1L and 1R. My student saw the air carrier medium large transport about 3 seconds before potential impact into our lower left side. As I looked to our left after my student's call, it was obvious that the medium large transport, which was in a climb had already started an evasive turn to his right to pass behind us at our altitude, while continuing his climb.

Title: CLOSE PROX GA SMA ON DUAL CROSS-COUNTRY ACR MLG ON DEP CLIMB FROM IAD.
Narrative: I WAS SHOWING A STUDENT HOW HE COULD FLY FROM W18 LAUREL SUBURBAN ARPT, TO W92 SKY BRYCE, W/O HAVING TO TALK TO ANY CTLRS, AND DO IT LEGALLY AND SAFELY! HOWEVER, WE HAD CONTACTED WASHINGTON FLT SVC FOR AN UPDATE ON WX ABOUT 5 MINS EARLIER AND WE'RE TOLD WE WERE #5 IN LINE FOR INFO. IF WE HAD RECEIVED AN IMMEDIATE OR MORE TIMELY BRIEFING WE WOULD HAVE GONE BACK TO MONITORING DULLES DEP CTL AT AN EARLIER TIME. THIS IS WHAT I ENCOURAGE MY STUDENTS TO DO IN ANY EVENT, EVEN IF THEY DON'T WANT TO TALK TO APCH/DEP. AS WE PASSED N OF DULLES IAD, OUR L WING BLOCKED OUR VIEW OF ACFT DEPARTING ON RWY'S 1L AND 1R. MY STUDENT SAW THE ACR MLG ABOUT 3 SECS BEFORE POTENTIAL IMPACT INTO OUR LOWER L SIDE. AS I LOOKED TO OUR L AFTER MY STUDENT'S CALL, IT WAS OBVIOUS THAT THE MLG, WHICH WAS IN A CLB HAD ALREADY STARTED AN EVASIVE TURN TO HIS R TO PASS BEHIND US AT OUR ALT, WHILE CONTINUING HIS CLB.
