The Little Arrow That Could
About once a week I'll hear someone contact my tower (class D) with a radio call like this:

[PART 1]
"Pilot: DuPage Tower, RV 123AB"
"Tower: RV 123AB, DuPage Tower"
<Crickets for 5+ seconds>

[PART 2]
After long, awkward silence on the channel...
"Tower: RV 123AB, DuPage Tower, say request"
"Pilot: Oh, uhh, I'd like to fly through your airspace"
<then they start exchanging details: position/altitude/altimeter setting/etc>

Almost invariably it's someone looking to transit the delta, and technically once you've gotten that transmission back from tower acknowledging you in PART1 of your initial call you're allowed into the delta. But I don't think I've ever had a case in the deltas where I've flown where tower is content with a radio call-up like that. Typically there is a bit of annoyance in their voice when they have to call you back and ask you what you want.

I'm curious if there's any instructors out there who teach people to just make the initial radio call without more information, or pilots making calls like this? Do you ever encounter cases where tower acknowledges you, implicitly clearing you into the airspace, but then doesn't immediately ask for more?

[Specifically curious about class delta interactions. When talking on busy APP/DEP channels I know it can make sense to do a preview call "RV 123AB w/request" and wait for an invitation to say your potentially long-winded flight following/approach request.]
 
Unless they’re noticeably busy, I usually make the full call at a Class D when I’m around 15 miles out.
 
Very rarey I’ll hear something similar:

“XXX tower, Cessna 123”
“Cessna 123, go ahead”
…
<long pause>
…
“Cessna 123, you still there?”

And hilarity ensues.
 
Sometimes busy approach controls have recommended callsign-only initial callups from VFR aircraft, but it's not the recommended procedure when contacting a class D tower.

My delta can get pretty busy, but I've always been able to find an opportune time to slide in a full request on the initial call-up since landing/transit calls are quite brief.
"DuPage Tower, Arrow 123AB 10 south-east landing with foxtrot"
"DuPage Tower Arrow 123AB 10 south-east at 2k feet request transition through your airspace to the northwest" (and FlyingRon's call is even more concise, so I might adopt that one now :) )

I just don't think I've ever seen a situation where a call-up with your tail number at a delta was what the controller was looking for, it always necessitates a subsequent call that takes up even more time on the channel.

App/dep be a bit different with non-stop comms, especially in the chicago area. There I always do an initial abbreviated call "Arrow 123AB w/request" and they'll hit me back for my request when they have an opening, which on some occasions is a few minutes later.

EDIT: for clarity.
 
I used the same call-up on every flight to get back into Dulles when I was there... Navion 5327K 25n 3000 landing dulles, parking landmark. Reliably got me in when they were ignoring other VFRs.

Unless the frequency is really busy and I need to squeeze my request in there, I don't use just my callsign.

I leave out "with request" because the fact that I want something is implicit in the fact that I am calling them.

“DuPage Tower, Arrow 123AB, 10 south-east with foxtrot.”
(could be a local thing but the D’s I’ve entered don’t seem to care about ATIS if not landing)

“DuPage Tower, Arrow 123AB, 10 SE, transition NW 2000 feet.”
(FlyingRon repeated the word “south”; I would only add the 2000 feet at the end if that’s the altitude I want for the transition)
 
I was once on a frequency and there was a Mooney on (I swear it sounded like a Mooney Mite with the canopy open) who answered every ATC transmission with "There ya go."

“Chicago approach, Mooney 123 with VFR request” gets a different response than “Chicago Approach, Mooney 123 with IFR request.”

I once flew with a captain that called every controller "Center Dude", "Approach Dude", or "Tower Dude."

I agree that including the type of request is useful. It's also recommended in the AIM.

Really, how so?
They're either working your or expecting a handoff. A pop up IFR ain't much different than a popup VFR?
 
If only the AIM had recommendations on how to make an initial call up...

  1. Contact Procedures
    1. Initial Contact.
      1. The terms initial contact or initial callup means the first radio call you make to a given facility or the first call to a different controller or FSS specialist within a facility. Use the following format:
        1. Name of the facility being called;
        2. Your full aircraft identification as filed in the flight plan or as discussed in paragraph 4-2-4, Aircraft Call Signs;
        3. When operating on an airport surface, state your position.
        4. The type of message to follow or your request if it is short

agreed
I know it's often recommended but I always thought it was redundant, takes up frequency "bandwidth", and to my ear it just sounds bad.
 
Who you are ,where you are,what you want ,in the northeast they like you to have the atis.

For sure. But my question was not really around the proper way to call up a delta. If anything I'm curious why people don't do it using the proper method.

The question was around whether class D towers ever really find it sufficient for you to just say "City Tower, RV 123AB" and get a response back "RV123 AB, City Tower" and then you consider yourself done.
People do this with some regularity at my field, specifically when they're transiting, and then tower has to radio them back and ask what they want.

I don't know if they do this to save space on the channel, or they think all they need to do is have that initial call-up.

Thus I was curious if there were instances outside of my area where it was more common or made more sense to hear the abbreviated call-up that only provided your tail number.
 
If the tower is busy and it's hard to get a transmission in, just the N-number and their reply "establishes 2-way communication" and you can enter the D, work out what you're doing later when they have time. If it's not busy, the full "who and where you are and what you want" is more appropriate.

I have a friend who flies for Southwest and is a surfer and windsurfer, wouldn’t surprise me.
 
Back when I was learning to fly at CPS, the practice area was just south of Dupo, a small hick Illinois town that was the usual reporting point and initial callup when returning. One day coming back, I called, "Bi-State tower, Cessna 12345 over beautiful downtown Dupo for landing." (I think I had watched a Laugh-In rerun the night before, some will remember their "beautiful downtown Burbank" routine.) There was just the tiniest pause before the tower replied, "Roger Cessna 12345 over beautiful downtown Dupo, enter and report a left downwind..."

Off course the tower radio was always playing in the flight school office, so I got ribbed about it for a few days... good times.

I was taught who you're calling, who you are, where you are, what you want.
 
At many (most?) Class D’s the tower controller can also be the ground controller/clearance delivery at unpredictable times so saying one can give the full request when the tower isn’t busy is a misnomer; unless you’re listening to Ground, you may not realize the controller is busy but you just don’t know. That’s why I just tend to make my first call with my N number unless I’m IFR and was just handed off by Approach, then I’ll say my N number, location, cleared approach, and ATIS.
 
i was taught to do the abbreviated call, wait for a response and then give details. nowadays i play it by ear. if not busy, i do the full call. if busy, i go with what i was taught.
 
There's a lot of potential word economy in calls to a D. I'm in puppy mill land and a call that can take 5 or 6 seconds drags on forever. Example "ER123 is approximately 10 nautical miles north of the field. Request closed traffic and we have ATIS information ECHO".

My call is "Cherokee 123 10 north with echo full stop".

Throw away words that triple the time talking to the tower;
- "Approximately" - who cares?
- "Nautical" - what else would you be using?
- "of the field" - what else would your position be relative to?
- "Request" (maybe to be polite, but still unneeded)
- "We have ATIS Information ECHO" (hint, the only word that matters is ECHO, "with ECHO" works too)

That is interesting. I had to go look. Dupo is too close (in the current class D), so that is why it isn't used anymore! The Billiken students tend to make nice brief calls like they should. The other flight schools at KCPS . . . not so much though still not too bad. The practice area is still south of Dupo.

KCPS is often pretty busy with traffic, but with the brief "RV123 15 south, inbound with whiskey" I always use the full. Sometimes they ask to repeat something, but controllers are perfectly capable of ignoring excess when they are also talking on ground.

You consider yourself “done” with that type of transmission but the controller is going to get intentions at some point. They’re just not going to leave the situation up in the air. If I were in tower I’d reply “RV123AB City Tower, City ATIS Alpha, say intentions.”
 
10 miles out:

"Renton Tower, Cessna N12345 is over auburn with Romeo, full stop"
"Cessna N12345, fly direct for rwy 34, report Valley Medical Center"
"Renton Tower, rwy 34, report valley medical, N12345"

“Renton Tower, Cessna 12345, Auburn, Romeo, full stop.”
“Cessna 12345, Renton Tower, fly direct runway 34, report Valley Medical Center.”
“Direct 34, Cessna 345.”

I’ve never had ATC ask for further readback beyond vectors, altitudes and runway assignments.

A lot of training traffic, so it's 50/50 if they remind you about the mandatory VFR reporting point at Valley Medical

Additionally (and you wouldn't have reason to know this) Auburn is both a town and a pilot controlled airport (S50), so your call leaves ambiguity of am I taking off from the airport, or passing over/near it.

Technically on the ATC side is acknowledging the instruction. A lot of pilots don’t realize that 99% of clearances and instructions don’t require a read back.

Do you really need to say "full stop"? Most class D's I've been to, that's the default assumption.

My airport has so much student traffic that my default landing call is:
"dupage tower, Arrow 123AB, 10 south east, landing full stop with bravo".

Otherwise they might ask what I plan to do because maybe 50% of the people calling up on radio aren't landing (we have lots of student traffic and are a destination for people practicing D comms, it seems). They'll end up asking for the option or a full stop taxi back (the latter usually at night).

But adding the verbose "landing full stop" segment of the radio call takes less than half a second and eliminates any ambiguity.

Amusing side-thought -- since tower answered back with the N number (thus 2-way comms established), could not this RV now drag his jowl through the class D any which way he wishes, all while ignoring any subsequent comms?

Bad form surely, but... I feel like a tower controller who was grouched about an incomplete call should play "defense" and respond with "Aircraft calling DuPage Tower, say request" instead? :)
