What is an ESA?
ESA - Emergency Safe Altitude - 1,000’ (2,000’ mountainous) above highest obstruction w/i 22 NM
What is a Low Level MSA?
MSA - Minimum Safe Altitude - 1000’ above highest obstruction w/i 5 NM
What is a Low Level IFR altitude?
IFR - 1,000’ (2,000’ mountainous) above highest obstrction w/i 5NM; should be rounded up to next 100’
Night VMC Low Level Altitude
500’ above highest obstruction to flight or 400’ plus one chart contour interval, whichever is higher, within 3NM
NVG Low Level Altitude
500’ above the highest spot terrain elevation or 400’ plus one chart contour interval, which ever is higher within 3NM
What is “mountainous terrain,” per the 202v3?
Mountainous Terrain - in absence of other MAJCOM guidance:
- areas defined in 14 CFR part 95.11 for CONUS, Alaska, Hawaii, and Puerto Rico.
- For all other areas of operation, use a 500’ surface elevation change over a 1/2 NM distance
SR Route requirements
SR Requrements:
- 1500 & 3
- Squawk 1200
- Max 250 KIAS
- Should monitor 255.4
- At or below 1500’ AGL
VR Route requirements
VR Requirements:
- 300 & 5
- Squawk 4000’
- Should monitor 255.4
IR Route requirements:
IR Requirements:
- Squawk as assigned
- Must obtain specific clearance prior to entering and exiting
- No weather requirements unless stated in the AP
IR/VR routes with ___ shall be identified by three numbers
IR/VR route with at least one segment above 1500’ AGL shall be identified by three number. When no segment is above 1500’ AGL, the route name will have four characters)
How does the MC compute Delta T?
Current ground speed to the next waypoint then flight plan speeds thereafter
Performance pages - TECH/MAN/FPLAN speeds
Performance Pages -
TECH - 4-engine tech order profile speeds
MAN - user defined
FPLAN - cruise phase only. Directs MC to KCAS/Mach as defined in the flight planning pages
Performance Pages - Climb/Cruise/Descent
Performance Pages -
CLIMB - after takoff (bottom of climb soft waypoint) up until top of clib for the initial climb phase (when you reach Route Data altitude. Defaults to Tech Order profile unless changed.
CRUISE - begins after T/C soft waypoint and ends at the T/D soft waypoint
DESCENT - T/D to B/D or FAF. Fuel based on idle plus .02 EPR
AT vs Cruise Altitudes/Speeds
AT Altitude - requires aircraft to be at a specified altitude
CRUISE FL - from the waypoint to the end of the flight plan or until the next RZ, AD, or MC approach segment
AT Speed - aircraft will be at this speed prior to the waypoint
SPD - MC adjusts to this speed after sequencing the waypoint
MC Wind hierarchies
MC Wind Hierarchies
- Atmospheric Model - assumes current atmospheric conditions within 200NM and within 4,000’ of the aircraft; updates every 5 minutes
- Next/ when on the ground:
- Spot winds and temp deviations
- Climb & descent winds
- Wind factors
- Calm/Standard Day
MC Altitude hierarchies
MC Altitude hierarchies
- AT ALT (or AT/ABOVE or AT/BELOW)
- CRZ FL (altitude passing a waypoint; on waypoint page)
- CRZ ALT (from route data page)
- With no modifications (on an airland flight), climb to cruise altitude at the highest 1,000’ altitude below the 300fpm cruise ceiling
MC Speed hierarchies
MC Speed hierarchies
- Speed Limit
- MAX SPD @ a waypoint (in climb or descent phase only)
- AT SPD @ a waypoint
- Speed to meet a FIX time constraint
- SPD (after crossing the fix)
- Tech order speeds
- (MC only provides recommended speeds during cruis & step descents)
Time Control -
Per the 3-3 (p 4-31), “Mission planning should include ___ and ___ to meet TOT in the even of early or late takeoffs”
Timing triangles and orbit points
Time Control -
Low Alt Orbit (less than 10,000’ MSL)
Low Alt Orbit:
- with AP on, 1.2 minutes per 180 degree turn.
- double that to get 2.4 minutes for a 360
- if you’re 5 minutes early add 1.3 minute legs (total of 2.6 minutes of straight-and-level) between the two 180s
- adjust for winds
Time Control -
High Alt Orbit
1% of TAS will equal time required for a 350 degree turn
e.g.at 420TAS, it would take 4.2 minutes to complete a 360
Time Control -
Explain the 10% rule
Add/subtract 10% of your planned IAS for 10 minutes to gain/lose 1 minute
(can be adjusted incrementally - i.e. a 5% change for 20 minutes or 20% change for 5 minutes)
Time Control -
Explain the Incremental Method
Time Control - Incremental Method
(use for deviations less than 1 minute)
-Divide planned IAS by 6
-Apply this increment to planned IAS for 1 minute to gain or lose 10 seconds
(e.g. Problem: 40 second late @240 KIAS. 240/6=40 knots. Solution: increase to 280 knots for 4 minutes)
Time Control -
Explain the Proportional Method
Time Control - Proportional Method
- Determine number of seconds early/late
- Change IAS by that number of seconds and hold for time in seconds equal to planned IAS
(e. g. Problem 30 second late at planned 240 KIAS. Increase to 270 KIAS for 240 seconds
