UALRATT (you and yuppyguppy need to take a chill pill) are we really having a pissing match about who can check ice from where...I think bottom line this comes down to a personal preference of the PIC and IAW company policy and aircraft limitations.
Honestly my opinion is, if a PAX says ice/frost/whatever is on the wing...I am going to sit on the ground until the ice/frost/whatever is melted, because it is a ton easier to explain a 30 minute delay while taxiing out to wait for some frost to melt than to answer to the FAA and Chief Pilot two weeks later when the one passenger wrote a letter to the FAA and the airline about you departing with frost on the wing.
I actually had a situation in BDL where we were cleared into position and hold while a king air took off from the crossing runway, once he was through the intersection we were cleared for takeoff, immediately after our takeoff clearance the king air declared an emergency and they were coming back to the field, tower canceled our clearance and asked us to vacate the runway, which we did...the engines were spooled up but we didn't need to hit the brakes to clear the runway. King air returned, landed and we took off...two weeks later I get a call from the Chief Pilot asking about a runway incursion in BDL and was wondering why I almost took off without clearance...turns out a private pilot wrote a letter to the FAA and the company (actually to Delta it was a DAL Connection flight) and said we took the runway without clearance and almost took off without clearance...luckily it was a matter of the company calling BDL tower and they got the tapes which proved otherwise, but nevertheless not a fun situation to be in.
Thanks Mike but I did take one before I posted cause I really had to...
