What I'd like to know is why, if controllers are so irate about unnecessary radio chatter, do some controllers/facilities just expect you'll switch over to Tower freq at some point on the taxi out (smart) while others (DEN ground, for example) spend probably 1/3 of their time telling airplanes to switch over to the Tower (not smart). Some days you can't get a word in edgewise while holding on the ramp, trying to contact Ground for taxi clearance (along with 12 other guys stepping on each other, not even counting the INBOUND airplanes) because the Ground freq is tied up with the Ground Controller himself going right down the line of aircraft already taxiing outbound:
"Frontier 859 monitor Tower 133.3"
"133.3, Frontier 859"
"United 567, monitor Tower 133.3"
"Roger, 133.3, United's 567"
"Champion 2962, monitor Tower now 133.3"
"Turty Tree and a Turd, Champion 2962"
Sound of loud screeching tones as four airplanes call simultaneously.
"Everybody just stand by, I'll call you when I get to you!!"
"Frontier 405, Frontier 405, are you still with me?
"Affirmative, 405"
"Frontier 405, monitor tower now on 133.3"
"Triple three's, Frontier 405, G'Day!"
"Good Day. Who's number 3 at 4E?" (since there are now 5 airplanes stacked up at 4E, unable to communicate)
"Skywest 456 is number 3 at 4E with October"
"Skywest 456, taxi via Lima to Echo Delta, then right on Echo Delta to Mike, Left on Mike to Runway 8"
"Roger, 8 via Lima, Echo Delta and then Mike, Skywest 456"
"And Skywest 456, monitor Tower on 133.3"
AAAAAAAAAGGGGHHHHHHH! Put up a freakin' sign or something, like SFO or LAX.
