Dockmaster Manual

 

INTRODUCTION

 

The Audrey simulator itself can be operated in every conceivable manner in the virtual universe, but without the Dockmaster station nothing else would ever move.  The virtual universe is dead without the Dockmaster station in operation.

 

The Dockmaster station software orbits the planet around the star, the moons around the planet, and rotates all of the above on their axis.  The weather map is dynamically moved over the surface of the moon as well.

 

This software also adds other vessels to the mix so that realistic delays, traffic conflicts, and procedures to work around these can exist.  The other vessels fly around on one of 13 different flight plans.

 

COMMUNICATIONS

 

One of the primary duties of the Dockmaster is to communicate with Audrey and to simulate two-way communications with the other vessels.  All ships, including the Audrey, require clearances to undock, land, takeoff, dock, and to transition from one control area to another.

 

Communications with the Audrey can be lost if diligence is not maintained at all times.  The communications run on a FTL (Faster Than Light) self-destructive carrier that allows instantaneous communications within certain range of objects.  The type of objects dictates the effective communication range between the two objects since the carrier disperses wider with range and therefore a larger collecting surface is required for far away signals.

CENTER (Communications Encompassing Network with Topography Elusive Resonance) has the most powerful transmitters and the most sensitive receivers.  No practical range limitation exists in this simulation for communications between the CENTER and another object.  CENTER is simulated to be handled by Lycia, the third planet in the system and is utilized by ships (including Audrey) anytime no other frequency is appropriate, usually for transition between docks or planetoids.  The TER (Topography Elusive Resonance) technology allows communications to operate on any side of the planetoids ostensibly through the ground.

 

GITADS (Ground Integrated Terminal Approach and Departure Systems) works up to 100 km above the surface of the associated planet or moon.  This is used for all approach and departure operations with the surface.  If a city or dock control area overlaps this area, the city or dock has controlling authority.  It is easy to remember this since traffic is in closer proximity to one another in terminal areas like docks and cities.  GITADS also handles DOR (Directional Orbit Recalibration) operations when conducted within GITADS range.

 

COMMUNICATIONS (Continued)

 

Cities and docks have an effective range of 500km.  When a city and a dock overlap control areas, the city has control because there are more obstructions and fewer options close to the ground and vessels are in constant motion when flying in the atmosphere.

 

Ship to ship communications is limited to 250km.  No ships have controlling authority, so their communications ranges do not dictate control zones.

 

FREQUENCIES

 

There are 121 different frequency combinations available (the square of 11) ranging from 0 to 10 on a left and right channel selector.  Once a channel is selected, it takes about 3 to 5 seconds for the carrier to be isolated.

 

If you change the frequency for an object, all virtual ships using that object are automatically notified.  However, Audrey must be alerted to changes so the crew may look up the new frequency on the flight computer and set it in their EFIS (Electronic Flight Information System).  You can change the frequency of an object by selecting that object with the up and down arrow keys and then using the left and right brackets [] to modify it.

Your current frequency should match the controlling authority for where Audrey is.  It is your duty to advise Audrey when you are handing them off from one control zone to another so they can change frequencies at the same time that you do and you never lose contact.  If Audrey is not using the correct frequency, an alert will sound that Audrey is in violation of USDC (United Stellar Defense Coalition) regulations.  You can only set your current frequency on an object that has that frequency set.

 

 

FREQUENCIES (Continued)

 

For example:  If Audrey just penetrated the control zone for the dock called Gateway, you would go to Gateway on your list using the up and down arrow keys and once it is highlighted, hit “U” to “Use” that frequency as your current transmitting and receiving frequency.

 

VPT

VPT (Vessel Profile Transmitter) is used as a transponder to transmit vessel information for a given location once every 2 seconds.  When interrogated, information about each vessel including name and flight number is given.  Without the VPT active on a vessel, the only way you can tell which direction they are heading is if they are moving.  It is recommended to have the VPT on for all vessels at all times.  It allows the Dockmaster to quickly identify vessels and keep them separate for flow control purposes.

 

SPECIAL SPEECH

 

Two more ways to communicate include the Prowler speech and the Audrey Speech.  The Prowler speech can be used with any ship.  It allows you to assemble phrases from a limited list of words for extra punch when Audrey (or another ship for that matter) has a run-in with the law.  The Audrey speech is specifically for Audrey and it will allow you to type in any English phrase (or for our International use, any set of phonemes) and the onboard flight computer in Audrey will almost immediately utter it.

RADIO SILENCE

 

You may use this feature if you do not want a vessel to transmit the normal radio calls for clearance requests, initial calls for new control zones, or confirmations of hold and release orders.  Select the ship that you wish to use this feature on and hit “E” for radio silence.

OPERATION PRINCIPLES

 

The throttle is located as the power quadrant on the pedestal between the two crewmember stations.  This throttle system is used for operating the four (4) primary or main propulsion engines by wire.

 

For ease of use in space flight, rather than manipulating the output thrust of the engines as with conventional aircraft, this vessel incorporates a “velocity seeking” (VMS) system.  The desired velocity is selected exponentially from 0 km/s to 10 km/s in normal mode and 0 km/s to 1 km/s in docking mode (7).  The computer then fires thrust in the most efficacious manner to reach this desired velocity.

OPERATION PRINCIPLES (Continued)

 

Similarly, the Thrust Reverser (6) selects the desired velocity as a positive or negative value and the computer determines whether forward or reverse thrust actually needs to be fired.

 

Furthermore, if turning the vessel or encountering gravitational pulls or friction as a result of atmospheric entry alters the forward velocity vector, the computer will strive to maintain the selected velocity automatically.

 

The conventional direct modification of thrust output (MOTO) can be selected by mode through the Primary Thrust Control Mode Toggle (3).  Since the velocity can easily get out of hand in the relative absence of resistance in space, this is recommended only for use in the atmosphere.  It is arguably easier to continue to use the VMS system in the atmosphere, as the transitions are easier between atmosphere and orbit and vice-versa.  In this mode, the Thrust Reverser (6) acts as a true manual activator of the thrust redirection.

 

PDRT Thrust (1) is more efficient below 38 km; therefore the checklist calls for its use only in that range.

 

Normally the Symmetrical Thrust Control Lock (10) is left in the locked position except in an engine failure emergency.  CAUTION: This controls inboard and outboard engine pairs, NOT port and starboard engine sets

 

There is a detent in the stroke of the throttle control, which is more evident when the Friction Lock (13) is set high.  Just past this detent to the bottom of the stroke is a 0 km/s requested speed.  It is most useful NOT to pull the control past the detent unless the vessel will be at station keeping when the crews’ attention is diverted from operation of the vessel.  It is also easier to operate the throttle for fine thrust controls (such as in docking) if operations are kept above the detent.

 

There is an upper detent, which automatically selects 100 km/s in normal mode or 10 km/s in docking mode (7).

 

The Primary Thrust Control Toggle (3) simply selects whether or not the computer should be attempting to match the control input.  This is useful when selection of a desired speed it to be laid in without immediate reaction of the computer.  For this reason, this toggle must be operated when the vessel is first powered up in order to deactivate this incorporated safety feature.

 

The use of SLT and SLR thrust modes (7) is outlined in the “Flight Controls” system description.  The effects of the PDRT Thrust (1) on these flight controls and the flaps are also covered in that section.
