Final comments on Near-side / Far-side, and Crossing Restrictions
Depending on where your final flight planned checkpoint lays, and from which direction you
are approaching destination airport reference the active landing runway, you will hear any one
of the following crossing restrictions:
Radar Contact ATC Basics
Version 4 December 2, 2007

“(call sign), cross four zero miles from (checkpoint) at one one thousand, two five
zero knots. Altimeter xxx”. (Final checkpoint 5m or less from destination airport,
Near-side)
“(call sign), cross four zero miles from (checkpoint) at one two thousand. Altimeter
xxx”. (Final checkpoint 5m or less from destination airport, Far-side)
Radial/DME Crossing Restrictions (above) require final checkpoint to be a VORTAC. If
your final checkpoint is something other than a VORTAC (waypoint, intersection, NDB etc.),
and even if this final checkpoint is closer than five miles from the arrival airport, you will get
one of the two following crossing restrictions:
“(Call sign), descend and maintain one one thousand. Reaching one one thousand
reduce speed to two five zero knots. Start down now please. I need you level in
thirty miles or less. Altimeter xxx”. (Final checkpoint >5m from destination airport,
Near-side)
“(call sign), descend and maintain one two thousand. Start down now please. I need
you level in thirty miles or less. Altimeter xxx”. (Final checkpoint >5m from
destination airport, Far-side)
NOTAMs and Crossing Restrictions
If you checked NOTAMs for your arrival airport, this is the time you start looking out for
those mountains. Your crossing restriction will include the NOTAM Advisory. Clearances
will be preceded by the phrase „when able‟ or „if feasible‟. That gives you some latitude to
disregard instructions which would otherwise get you plastered on the side of a mountain. Be
aware, the RC controllers issue heading and altitude clearances based on where you should
be, not necessarily from where you are. To every extent possible, accommodate your control
clearances.
TIP - Remember, use the MSA entry boxes on the Controller Info to accurately enter
or amend the area‟s safe altitudes per your arrival charts and/or approach plates.
Unlike NOTAMs on the departure side, with arrival NOTAMs there is no need (nor option) to
advise any controller you are able to adhere to instructions.
With respect to arrival NOTAMs, expect very similar handling in the descent and arrival
phases of your flight, regardless of level of ATC service.
Enroute Holding Patterns and Delay Vectors
RC features Holding Pattern/Delay Vectors in both enroute and as options after Missed
Approach. This section covers enroute only.
Both pilots and controllers dislike delays. In a perfect world there would be none.
Unforeseen traffic saturation and weather can wreak havoc on the ATC system. There will
come a time when you will have to accept delay vectors or holding instructions, just as the
real-world pro‟s do. RC will let you choose whether you will be held always, or never held,
or held based on weather. The chances for being held for weather are as follows:
Radar Contact ATC Basics
Version 4 December 2, 2007

If 10 or more rwys (5 pavement or greater):
35% hold – 65% no hold = Visibility 3m or less, and ceiling 400ft or less
20% hold – 80% no hold = Visibility 3m or less, or ceiling 400ft or less
5% hold – 95% no hold = Visibility > than 3m, and ceiling > than 400ft
If 6 or 8 rwys (3 or 4 pavement):
35% hold – 65% no hold = Visibility 2m or less, and ceiling 400ft or less
20% hold – 80% no hold = Visibility 2m or less, or ceiling 400ft or less
5% hold – 95% no hold = Visibility > than 2m, and ceiling > than 400ft
If 4 or fewer rwys (1 or 2 pavement):
35% hold – 65% no hold = Visibility 1m or less, and ceiling 400ft or less
20% hold – 80% no hold = Visibility 1m or less, or ceiling 400ft or less
5% hold – 95% no hold = Visibility > than 1m, and ceiling > than 400ft
Normally the controller will give you the option of taking the delay using holding patterns or
delay vectors. If you prefer holding instructions choose „Holding Pattern‟ on the Pilot's Menu.
If you are in the mood to allow the controller to fly your airplane for the duration of the delay,
choose „Delay Vectors‟.
IMPORTANT NOTE – If your co-pilot has the aircraft controls, Delay Vectors will
be mandated by the controller, regardless of who has the aircraft comms.
