4.10.2 EMCC FDO Deployment Checklist Upon EMCC activation, the on-console FDO Traj will page the EMCC FDO, GPO, Traj, ESE, LSO & begin copying databook material detailed below. The EMCC FDO & or Traj will report to JSC to collect hardware listed below & place in the designated staging area at the front of the WFCR (one exception noted below). If insufficient time is available for the EMCC FDO Traj to make it to JSC, then the on-console FDO Traj will gather all materials if at all...

SECTION

For deorbit burnout conditions with current Hp above target Hp, some amount of pre-bank will be required to help bleed off the excess energy. The pre-bank table in the Entry Checklist (Figure 4.7-6) specifies pre-bank as a function of AHp (current - target), and also includes redes information for Capture Hp scenarios. The DSCT-28 table is flight-specific, and is generated for the prime EOM KSC and EDW deorbit opportunities. For each site, the circled DHp represents the highest DHp that allows...

Entry Flight Dynamics Officer FDO Responsibilities

Evaluate and recommend landing site. 2. Evaluate and recommend deorbit opportunities. 3. Evaluate and recommend orbit adjust maneuvers for optimization of end of mission. 4. Evaluate and recommend landing runway and configuration (aimpoint, speedbrake logic). 5. Perform deorbit targeting (balance tradeoffs target steepness, propellant available, thruster downmoding time, center of gravity (CG) management). 6. Generate the Deorbit, Entry, and Landing (DEL) Preliminary Advisory Data (PAD), the...

Thermal Tradeoff Line

FDO and ESE must verify that the DMP deorbit solution indeed satisfies these targeting parameters. This is done by running an EDS simulation and checking output on the Entry Digitals display. EDS-predicted NCYCLES should be equal to the value input on the DCT (NCYCLES+1 is also acceptable). Degrees off the thermal trade line is shown as ATTL (up to 5 deg is acceptable). D23C can be graphically checked on the Drag vs Vrel plot. Maximum WLE temperature (CP3) should also be below 2950 deg (100...

Preface

Volume IV of the Flight Dynamics Officer Console Handbook was created through the efforts of many people within the Flight Design and Dynamics Division (DM). It documents Flight Dynamics Officer and Trajectory Officer information and procedures for the deorbit and entry phases of flight as well as Emergency Mission Control Center (EMCC) operations. Below are some of the names of the people who contributed to this volume G. T. (Greg) Oliver, NASA E. P. (Ed) Gonz lez, NASA B. R. (Bruce) Hilty,...

Deorbit Maneuver PAD

The DEORBIT MNVR PAD contains the D O burn data required by O B guidance. The PAD is structured in the same manner as the O B MNVR EXE display in order to aid the crew in the manual input of the burn data if a key-in is required. Normally, the D O burn targets are uplinked using a command load. If the targets are uplinked, then the only items read off the DEORBIT MNVR PAD are TGO, any notes, and TIG if it has changed from what was given to the crew earlier. If command capability is lost, the...

High Speed Displays

This section describes the FDO's high-speed entry displays. The standard set of enhanced displays for use from EI to landing are brought up by selecting High Speed Entry FDO from the displays menu. The displays include VREL (and Delaz) vs. RGO, Altitude vs. RGO, EOW vs. RGO, Entry Groundtrack, Log Log, and Entry Digitals. The four parameters that are plotted against RGO, as well as the Entry Groundtrack, are sequenced and re-sized automatically during entry to provide optimal viewing. The Log...

Trajectory Ops CCB Required Disclaimer All applicable software items on the FDO DNAV pulldown menu should be verified using the Flight Load Checklist (FLC) between L-30 days and L-15 days. The FLC must be performed using a CERT (MIS or SIM) activity for the flight of interest. If possible, applications should be used during a simulation run to verify functionality. It is the responsibility of the discipline to identify or arrange for an appropriate activity in which to perform the FLC. The...

Emergency Mission Control Center Emcc

The purpose of EMCC is to provide a backup control and monitoring capability for the shuttle in the event the MCC becomes unusable. EMCC operations are conducted in one of the firing rooms at the Launch Control Complex (LCC) at KSC. Possible activation scenarios include fire, sabotage, hurricane, or terrorist attack that renders the MCC inoperable for greater than 10 hrs*. The EMCC team is made up of approximately 17 flight controllers, including all front room operators, plus Weather, Entry...

Maneuver Generation and Evaluation

The maneuver generation process is simply a matter of reviewing the tables for proper configuration and establishing a TIG for the selected landing site. For EOM, the DCT is usually configured with 2 OMS 1 OMS in column 1, 1OL 1OL in column 2, and 2 OMS 1 OMS shallow in column 3. The primary runway should be selected for the landing site. The first activity is to determine the optimum deorbit AV requirements for steep and shallow targets. The propellant required to deorbit is passed to PROP and...
