For additional safety and route deconfliction, what will planners (that’s us) also annotate on the chart?
Areas where an IR, VR, or SR route crosses your planned route
When using VVOD……
In addition, when using VVOD aircrews will use the LIMITED DISTRIBUITION statement and include “VVOD DD MM YY” with VVOD file creation date.
Define Emergency Safe Altitude (ESA)
Emergency Safe Altitude: Provides 1,000 feet (2,000’ in mountainous terrain) above the highest obstruction to flight within 22 NMsof route centerline
Define Minimum IFR Enroute Altitude (MIFR)
Minimum IFR Enroute Altitude: Provides 1,000’ feet (2,000’ in mountainous terrain) of obstacles clearance above the highest obstruction to flight within 5 NMs of planned route centerline. (OCONUS it widens to 10NM of centerline)
- This altitude should be rounded off to the next 100-foot increment *
Define Minimum Safe Altitude (MSA)
Minimum Safe Altitude: Provides 1,000 feet obstacle clearance above the highest obstruction within 5 NMs of planned route centerline.
Define Night VMC Altitude
Night VMC Altitude: Provides 500 feet of clearance above the highest obstruction to flight, OR 400 feet plus one chart contour interval above the highest depicted terrain contour, whichever is higher, within 3 NMs of planned route centerline
Define NVG Enroute Altitude
NVG Altitude: Provides 500 feet of clearance above the highest spot terrain elevation, OR 400’ plus one chart contour interval above the highest depicted terrain contour, whichever is higher, within 3 NMs of planned route centerline.
BONUS: Must identify obstacles NLT 3NM before them and laterally deconflict. If you cannot identify them, then climb 500 feet above them to be safe.
Explain what “Route Centerline” includes besides just the fucking centerline….
Route centerline includes the aircraft turn radius over each turn point. (i.e. accounting for aircraft gross weight, angle of bank, speed, pressure altitude, temperature).
Ceiling, Visibility, Speed and Squawk for an SR / VR / IR route.
SR: Required 1500’ ceiling, 3 NM visibility, no faster than 250 kts, squawk 1200
VR: Required 3000’ ceiling, 5 NM visibility, no speed restriction, squawk 4000.
IR: No ceiling or visibility requirement, no speed restriction, squawk as assigned by ATC.
Situational Question: If we are flying VR106 and enter the weather, what will our reaction be?
Abort the low-level, climb to an altitude at or above ESA, contact ATC, and coordinate for a clearance.
GPWS / TAWS / RA Settings for the Low Level Environment
DAY: GPWS set 100 feet below planned route alt
TAWS set 100 feet. period.
RA set MKR 50 feet below planned route alt.
Night: GPWS set 400
TAWS set 300
RA set MKR 50 feet below planned route alt
Hey Fucker, how do we calculate an EARLIEST takeoff time?
Constrain the flight plan to something like Vmsr or the slowest desired speed. Then enter an AT SPEED at the beginning of the flight plan. As long as you still have the speed restrictions in there, it will honor the 250 kts below 10,000 feet and then assume tech order above 10,000 in the absence of a faster or slower constraint like 330 or 290 etc. This is telling you the earliest you can takeoff, fly slower than molasses and make your TOT.
NOTE: MUST BE IN TRIPPLE FLIGHT PLAN FOR THIS TO WORK
Hey Fucker, how do we calculate an LATEST takeoff time?
Force the flight plan to fly the maximum desired speed… You can just drop an AT SPEED of 330 or 310 at the beginning of the flight plan and it will honor 250 below 10,000, then assume an acceleration to be AT THAT SPEED as early as possible. You could also achieve the same result by entering a MAN SPEED in the performance pages.
NOTE: ** MUST BE IN TRIPPLE FLIGHT PLAN FOR THIS TO WORK **
For more precise time control on the ground, in-chocks, getting your life figured out… what can you do in the box to nats-ass your timing?
you can set OVERLY to YES on an individual waypoint or all of your waypoints if you choose…. also, you can always go DIRECT to your next point or perform a Direct-to-Intercept. Look in the -2 for the button-pushes for a Direct-to
Enabling LL Mode on individual points does what?
Adds 15% fuel burn. Also affects display of vertical obstructions on ND chart format. If you enable formation mode on individual points, that will add 5% fuel burn for maneuvering.
MC Speed Hierarchies
Speed Limit (structural / PRFM page)
MAX SPD for climbs and descents (waypoint page)
TECH, MAN, or FPLAN (PRFM page)
- AT SPD (waypoint page)
- Speed required to make a fix TOT
- “soft” SPD (waypoint page)
MC Altitude Hierarchies
AT Altitude, AT/BLW altitude, AT/ABV altitude
CRZ Flight Level Constraint (waypoint page)
CRZ Altitude (RTE data page)
In the absence of any changes to the vertical profile, ie: you haven’t set any specific altitude constraints in the waypoint pages or RTE Data page etc, what will the Vertical Profile (VPF) calculate?
VPF calculates a climb to an initial cruise altitude at the highest 1,000’ altitude increment below the 300 foot per minute cruise ceiling (MAX ALT on the performance pages).
Step climbs to the next higher 1,000’ altitude increment become available as you get lighter and the temperature allows. The max altitude the MC is programmed to FL450.
What is the absolute fastest or slowest speed the MC will guide you to or “plan” for you to fly for a given configuration?
Regardless of speed selection, the MC will not guide to less than Vmma for the current
configuration [1c-17a-1-2, 1-661] or more than Vne-10 (339 KCAS)
MC Airspeed targets and adjustments when you have a time constraint… “Next 5”
With a time constraint defined (like placing a FIX for your low level entry/exit), the Mission Computer calculates airspeed targets and adjustments that will place the NEXT FIVE fix constraints’ ETA’s within their tolerances.
The MC uses the distances between the TO and succeeding constrained waypoints, the altitude profile, and the Atmospheric Model winds and temperatures to derive weighted average airspeeds between Vmma and Vne.
Calculations for remaining FIX constraints and ADVISORY constraints use Tech Order speeds or speeds of higher priority.
What does placing a “soft” SPD on the WAYPOINT pgs cause the MC to think? Ie: you just finger-fucked the waypoint with that soft limp-dick “SPD”…. what will the MC assume for you speeding up or slowing down etc?
When a SPD is defined on the SPD CSTR AT WAYPOINT page, the MC adjusts to
this speed AFTER sequencing the waypoint. In other words, your new Delta-T is based upon hitting that point at your CURRENT speed and THEN accelerating after you sequence the point… this is the opposite of an AT speed which tells the MC’s brain to accelerate NOW to arrive AT that point AT that speed…
Be advised: The MC does override soft SPD to honor FIX time constraints
Explain the atmospheric model and how often he crunches.
In flight, the MC uses ADC and IRS data for temperature, temp-dev, PA, HDG, drift, GS, and wind.
The eyes of the atmospheric model, lets call him Big Daddy Atmo, looks down-track 200 NMs and 4,000’ above AND below the aircraft. Daddy Atmo updates his projection every 5 minutes.
