Humars's ATC Tracking Thread - [CLOSED] @N/A

Don’t think too much about it. Personally, I usually send the command to airliners when they are below 60 knots and to GA planes when they are below 40 knots if that helps you. But when it gets busy I send it when I have time to do so. There are more important commands which should be send at a specific time.
So yeah as I said it wasn’t a mistake but an advise :)

I’m open! Here is all the necessary details:

Airport: LTAC
Server: Training server
Winds: 070@5 (information is subject to change, make sure to check the current winds for up-to-date information)
Visibility: six (6) statue miles (subject to change, check METAR for updates in visibility)
Currently active runways: Runways 03L and 03R are currently active (all information is subject to change, this is only initially recorded information and you should check currently active runways)
Elevation: 3127ft
Estimated time: 20 minutes-1 hour (special circumstances that will require me to stay will allow for a one 1 hour session, anything of normal circumstances will result in only for 20-30 minutes of minimum average)
Pattern work is allowed and encouraged.
Any & all crucial & vital feedback is appericated for many mistakes I may make.

Note: I won’t be able to look in the IFC (Infinite Flight Community) website for most of the time during my controlling, so I apologize for any mistakes I may make in advance.

Also, if anyone wants mentions regarding the opening and/or closing times of my sessions, please PM (privately message) me or mention it here.

I’m now closed! Thanks to Turkish 1998 (who I’d like to apologize to for the technical difficulties when it came to the runway change from 03L to 03R ) and Eva 797 for coming to my session, with the first one coming as pattern aircrat and the other coming as an inbound respectively. Although not much traffic came, two aircraft coming to my session is quite enough (but I mostly wonder if they’re in the IFC (Infinite Flight Community).

Also, once again, if anyone wants mentions for the opening or closing of any of my sessions please dont hesitate to PM (privately message) me or say it here.

Also, just a quick question if anyone can answer, downwind can also be used as crosswind when the aircraft is requesting runway change or for any other reason?

Ola, I was Turkish 1998 have some feedback.

Ground control

  • I was the whole time taxiing through grass and you didn’t have me a warning. (it’s better to put your camera on bird mode over your airport, therefore you can see what kind of shenanigans pilots are doing).
  • Nice correction you gave me there (by using the Freq. duplicate instruction).

Tower control

  • Overall clearance were given a little bit too late for me. it is better to clear the person who is in pattern at cross wind (see image below).
  • While I requested runway change you said to me to remain slowest practical speed. Which was usefull to give, since I my speed was 242kts.
  • You gave me pattern instruction to enter right downwind, while I was on left downwind (so the appropriate instruction would’ve been enter left downwind, rwy XX)
  • From the moment you instructed me for the pattern, things became confusing hehehe. You told me to disregard last message but you then repeated the same instruction.
  • You first cleared me for the option without traffic, however, you corrected yourself and gave me a clearance with traffic (but between the two clearance use the correction, disregard last message option).
  • When I requested transition you gave me 10,000ft. Which was quite high!

You say here that the elevation (AGL) us 3,127ft. therefore just add 2,500ft and you have 5,627ft (5,500 or 6,000ft would’ve been the correct transition then).

Furthermore everything was good! Thanks for the controlling :-)! Hoping that the feedback I gave was useful and success on your journey to become an IFATC controller!


I saw charts for the airport and apparently the transtiiton altitude was at or above 10,000ft :/. I can provide further evidnece if you wish in PM, but I do understand your logical explanation.

About the grass thing, I noticed it immediately as I was supervising you but I didn’t know if I had a command in misc or not that said that you’re taxing on grass, so I didn’t know if I could do anything or not :/.

Yeah apologizes for the technical difficulties, usually I would know to just send the correct one command but things went haywire after I sent the pattern insturction (as you said), also as I was under time pressure so I wasn’t able to properly figure out if I should give the pattern instruction based on the heading of the opposite direction of the runway or the direction of the aircraft, henceforth which is the reason why I asked in my closing message if downwind could also be used as crosswind under reasonable circumstances :/.

Also, for the clearence, yes I immediately realized after a while that I forgot to give you the clearence on crosswind or early downwind, in my last session an IFATC member in the pattern had to go around because I accidentally forgot to give the clearence all together, which was eventually realized after the go around :/. I’m going to need some practice in proper timing I assume :/. I also don’t see any image :/.

As speed for airport frequencies is ground speed, I’m unable to properly identify your airspeed if I’m correct. Which meant I had to determine at the rate of nautical miles you were going to determine a rough speed, which is the only reason why I said to slow down :/.

However, setting this aside, I appreciate you attending my session today :/. Hope you have a fantastic day!

P.S.: This may sound like a desperate question, but since I want to see if anyone’s interested, would you like mentions for when my sessions are opened and/or closed?

There seems to be confusion regarding the “Transition Altitude” mentioned in approach plates. To quote directly from one of the tutorials here:

Transition Altitude: The altitude in the vicinity of an airport at or below which the vertical position of an aircraft is controlled by reference to altitudes (MSL)
Transition level: , Translation level is the lowest flight level available for use above the transition altitude. In IF this is standard FL180.

Here’s the tutorial on how to read an approach plate:

As mentioned in the ATC Manual, Tower’s airspace extends to 5 miles and 5000 ft AAL only. For an airport elevation of 3127’, your airspace would be till 8127’. You must give transitions below this altitude.

Could someone explain what the situation looked like when this command was sent? I’m having a hard time understanding why slowest practical speed was needed.

I have looked back to the replay and have to revoke what I have said (see below)

Since there were no in- or outbound traffic in the airspace. I’d say if there were other pilots who were in- or outbound then it was applicable.

It was not needed in this scenario

@Humars Why was “slowest practical speed” sent?

@TaipeiGuru This is the reason why he used that command.

Controllers should not be worrying about speeds unless a) there’s a risk of conflict with another pilot, obstacle, etc, or b) they’re going at an excessive speed (i.e. 800 knots). Seeing as neither was present, I would agree with your judgement that the command was unnecessary.

When I looked at Turkish 1998 as he sent the runway change request (@Menthesuphisth), I noticed he was going at an excessive speed, more than usual to the point where a base turn would’ve probably been not possible without overlapping the ILS cone and having to re-intercept, so I sent to maintain a slowest practical speed so he can make a base turn. I’ll relook at my replay version for further confirmation.

However, @Menthesuphisth since you still have the replay, what was your airspeed when I sent the command to mantain slowest practical speed?

Edit: According to my replay, it showed that Turkish 1998 was at 241 knots when I sent the maintain slowest practical speed command (if I’m correct, the knots shown is ground speed and not airspeed?

Oh alright, thanks for clarification!

Correct. However, you do not need to worry about their speed in this situation, as the pilot will be in control of the aircraft and adjust their speed accordingly to be able to turn base/final.

I’m now closed! I’d like to thank, in particular, @Aaron.C, for attending my session today alongside a couple of departing aircraft. It’s been a fun time, although I had to distract myself for more than an hour on things whole I await any pattern aircrat, such as observing the fateful crash of a 777-300ER and two aircraft somewhat very close to each other that is travelling to an unknown destination, it’s somewhat worth it. Hope all of you who attended, or not, have a fantastic/wonderful day!

Note: Those who attended to do pattern aircraft (@Aaron.C), if you’re able to give me any feedback whatsoever it will be very appreciated, but thanks anyways for attending.

I also like to give an honourable mention to @Menthesuphisth for allowing me to mention him, including personally PM’ing (privately messaging me) why he couldn’t attend, which is quite surprising and appreciated as well.

Hey Humars!

You did a pretty good job, hopefully some more people make it out next time so you can get some sequencing work!

My only comment for improvement would be if someone calls in on an ILS/GPS/Visual, if there is no radar facility that cleared them for that approach, then treat it like someone calling inbound. Pattern entry,sequence, clear. Other than that great job! Good runway changes and clearances!

I’m open! Here is all of the necessary details:

Airport: LSZL
Elevation (to make it clear if people don’t understand, the elevation of the airport): 649ft-650ft

Apologizes to @Nils_Esser for confusions as apparently he spawned in the aiport I initially opened and is doing patterns when I’m not there :/.

Also, if any of you haven’t realized yet, I have opened this particular airport to celebrate Marc’s promotion to moderator of the community :/.

Ok what was going on today?

Pattern Entry, Sequence, Clear

That is the order you have to follow.
If there is an aircraft on short final runway 08L which is cleared as number one the aircraft on left downwind runway 08L obviously can’t be number one as well. Also the aircraft on left downwind needs a sequencing so the pilot knows who he is supposed to follow.
You alxo shouldn’t use speed restrictions if they aren’t needed. If you sequence aircraft A to follow aircraft B you don’t have to tell aircarft A to maintain slowest practical speed. This is the pilots responsibility now.
If an aircraft is intending to land at the airport after a transition, it is necessary to send a pattern entry. This applies to every aircraft that is entering your airspace with the intention to land (or do a touch and go) as long as there is no Radar present.

So to sum up:

  1. Pattern Entry
  2. Sequencing
  3. Clearance
  4. Take your time
    Pilots won’t mind if it takes you a bit longer to send a command if the command is correct.
    That is way better than sending the wrong command fast.
    So just keep on practicing and I hope to be able to join your next session as well!
