Why Request Vectors for Visual?

ATC Visual Base Pattern Layout
ATC's view of an airbase.

Pros

  1. ATC can manage large numbers of both human and AI traffic at the same airbase.
  2. Pilots are processed in an orderly fashion. Everyone is guaranteed a slot to land eventually.
  3. Entire flights are handled in the same fashion. (With other approaches, humans and AI are treated as separate entities, often resulting in different approaches being flown to the same airbase.)
  4. Having a single authority manage air traffic should result in safer conditions.

Cons

  1. When the pattern is busy, vectoring can consume more fuel.
  2. This style of approach takes longer than others.
  3. There is a chance of being kicked out of the queue and being made to wait even longer.
  4. This approach requires visual landing conditions.

Normal Procedure

Flights should enter the pattern, follow ATC directives, and land safely. This is the ideal circumstance. Flying in close proximity with many aircraft, however, is rather dangerous if protocol is not kept.

Entering the Pattern

  1. Flights shall arrive within 30nm of the Destination Airbase to be in range of ATC Approach airspace.
  2. Flight Leads shall order their flight to switch to the appropriate Destination Approach Preset or Frequency. This is usually UHF 4, UHF 7, or UHF 10.
  3. Flight Leads shall request vectors for visual approach. This enters all members of the flight in the ATC Queue, as long as they are within 5nm of the flight lead.

ATC may give you information on initial contact, such as QNH. Each pilot should use this information and set the altimeter accordingly!

Note: It is important that all pilots in the flight are tuned to the appropriate frequency prior to requesting vectors. They will not hear ATC giving them vectors if they are not on the correct frequency.

Following Pattern Directions

One Flight Visual Approach
One flight successfully performs the approach.

The ATC will vector each member of the flight individually. The radio chatter on the ATC Approach frequency can get busy rather quickly. If an airbase has 4 full flights returning, that is 16 different aircraft that ATC is vectoring concurrently. Each pilot must listen carefully for his callsign to be called. It is imperative that each member of the flight follow every directive as quickly and as safely as possible to avoid a collision.

The ATC's instructions to a pilot will start with the pilot's callsign and will reference up to three variables:

  1. Heading
  2. Altitude
  3. Speed

An example directive might be, "Plasma 1-1, turn right heading 355. Descend to 5000. Maintain 300 kts." In this scenario, all three variables are explicitly mentioned. This is not always the case. All pilots will need to listen to the exact directive given to them while remembering what was given by ATC prior. Again, pilots must obey the directives as soon as possible in the safest manner.

If a pilot misses the directive, he may issue a "Say again" request to ATC Approach.

Orbiting

The ATC may ask a pilot to orbit for spacing at a given altitude. An example directive might be, "Falcon 2-2, orbit for spacing. 6000." This is a directive to begin a right-hand orbit at 6000ft. All directives to orbit are right-handed. If a pilot is asked to orbit above 4000ft, he may expect that there is traffic below him.

On Final

Eventually ATC will begin appending the landing runway to the directives. "Viper 1-3, turn heading 305. Descend to 4000. Maintain 270 kts. Vectors to final. Runway 18." This is letting the pilot know he's getting close to being handed off to ATC Tower, and he should expect to be vectored to a final approach for a landing on Runway 18.

Once ATC Approach tells a pilot to "Contact Tower on Final," the pilot should switch to the ATC Tower preset or frequency. This is typically UHF 3, UHF 8, or UHF 11. When he is within 6nm of the airbase and within 30° of either side of the threshold, the pilot must contact Tower and report "On final."

If all is good, Tower will give clearance and repeat the landing runway.

Note: It is NOT necessary to request landing clearance from the Tower. The pilot has already been entered into the ATC Tower Queue via ATC Approach. The Tower is expecting him to report that he is on final approach.

Adaptive Procedures

Four Flights on Visual Approach
Four flights attempting the approach. Some flights look lost.

With this many aircraft in close proximity, it is possible for disaster to strike. A pilot must maintain his Situational Awareness at all times.

Traffic Advisory Calls

Occasionally, ATC might inform you about incoming traffic. If ATC makes such a call, then ATC is concerned this traffic may be on a collision course.

A traffic advisory call might sound like, "Fury 1-3, traffic 11 o'clock."

  1. A pilot should immediately look in the direction cited. In the example case, it is 11 o'clock, which is to the front and slightly left of the pilot.
  2. Visual contact should be established with the traffic in question.
  3. The pilot must quickly make an informed decision whether to deconflict with the approaching aircraft. This is an incredibly dangerous situation, and should not be taken lightly. Changing course presents additional risks, even if it is required.
  4. Once a pilot has established visual contact with the traffic, is aware of the situation, and is in no danger, he may issue a "Traffic in Sight" reply to ATC.

Note: ATC will continue to warn the pilot about traffic until ATC is confident that the danger is over or the player acknowledges that he has the situation under control. A pilot may miss critical directives and be forced to abort his approach if he does not actively inform ATC that he has the traffic in sight.

Authorization Canceled

ATC may cancel a pilot's approach. The solution to this is to re-enter the queue all over again. A pilot must request approach all over again as he begins flying outside of the immediate vicinity of the airbase.

This cancellation of clearance might be due to flying too close to traffic, or disobeying directives. Alternatively, the runway may suddenly become unavailable. No matter the reason, the pilot must be ready to abort both the approach and the landing.

If a pilot absolutely cannot abort, he may declare an emergency.

Not Reporting Final

Not reporting when a pilot is on final disrupts the Tower's queue. The tower is expecting each pilot to report on final, so he may put flights in the final queue. When a pilot performs a landing without authorization, he puts the other flights at risk and confuses ATC. ATC may revoke the authorization of other flights.

Aborting

If a pilot cannot land safely, he should abort his approach. A pilot can abort during either his approach or his landing. Depending on where he is in the process, he should call out his abort to the ATC on either the Approach or Tower frequency. This takes him out of ATC's queue. For example, if he finds himself coming in too high and too fast on final, he should immediately inform Tower (not Approach!) that he is aborting his landing.

As with the case of authorization being canceled, the pilot should begin flying outside of the immediate vicinity of the airbase. If the pilot still intends to land, the pilot should attempt to get himself back into the queue as soon as possible by contacting Approach (not Tower!) and requesting vectors.

Note: A pilot not informing ATC that he is aborting the approach or landing can disrupt the queue.

Declaring an Emergency

If a pilot has an actual in-flight emergency, such as a fuel leak, the pilot may need to declare an emergency and land ASAP. In this case, it is appropriate to declare an emergency on the ATC frequency when in range and land immediately.

Note: Declaring an emergency is a very serious decision, as it disrupts the queue. A pilot should never do this simply for convenience.
