All arrival routes into Liverpool and Hawarden terminate at one of the 2 stacks; TIPOD and KEGUN. Aircraft should not proceed beyond the stack without ATC clearance.
Holding Procedures
The table below indicates the holding areas available to Liverpool:
| Stack | Axis and Direction of Turn | Minimum Holding Level | Maximum Holding Level | Holding Speed Limit |
| TIPOD | 119 Right Hand | FL60 | FL140 | 220kts |
| KEGUN | 006 Left Hand | FL60 | FL140 | 220kts |
NOTE - TIPOD arrivals should be used between 0700Z and 2000Z. Between 2300Z and 0700Z, KEGUN arrivals should be used. KEGUN arrivals may be used outside this time at the discretion of ATC.
Aircraft must cross SLPs (Speed Limitation Points) at 250kts or less, unless ATC has removed any speed restrictions.
When stacks become full, enroute holding further down the STAR takes place.
It is important that you keep the stacks laddered down so that levels can be freed up. In the stack, you can only clear an aircraft down to the next level when the previous aircraft has vacated the previously occupied level. There are two ways of doing this. 1) Ask the pilot to report leaving the level 2) When the mode C readout shows +/- 400ft from the assigned level, we can assume the aircraft has left the level. During busy periods, option 2) is the better one to reduce RT transmissions.
Ultimately, it is the pilots responsibility to ensure that he enters the stack at 220kts. To help him out, as he approaches the stack, if you want him to enter the hold bring his speed back early (By doing this, as he reaches the stack you may then realise he doesn't need to hold because the reduction in speed has created enough of a delay)
Aircraft should be informed of the length of delay expected in the hold. The usual phrases used are "Less than 5 minutes", "5 to 10 minutes", "10 to 15 minutes" and "15 to 20 minutes". If the delay is going to be over 20 minutes, Expected Approach Times must be passed to aircraft. It is important that an accurate delay is passed to aircraft.
Level Allocation
TIPOD
The minimum level that may be used in the TIPOD hold is FL60.
KEGUN
The minimum level that may be used in the KEGUN hold is FL60.
Inbound Releases
In reality, every aircraft inbound to Liverpool or Hawarden has to be released by area control to approach control. This is done over the telephone. This can be simulated on IVAO with the Intercom or via text chat.
A release message contains:
Example of a release phone call between WAL and GP RAD:
"Liverpool"
"WAL, TIPOD release, EZY123 at 9"
"EZY123, 9"
"RYR6 at 10"
"RYR6, 10"
"Correct"
"Roger"
Verification of MET and Aircraft type
Liverpool Radar is to verify that aircraft are in receipt of the latest MET report and are to verify the aircraft type, including type variants. The tower must be informed of any aircraft that are not the type as indicated on the flightplan.
