There is a cost for this activity
Who this is for: Instrument-rated pilots who want to practice high-altitude airport operations, rigid STAR step-down compliance, and terrain-ringed basin approaches in a realistic LOFT environment. Particularly valuable for pilots preparing for international operations or airline interview IFR evaluations where high-elevation hub procedures are standard topics.
CFII-led, LOFT-style IFR session in our G3000 Perspective Touch+ with GFC500 autopilot and G1000 NXi flight simulators (FAA-approved AATDs). This Master-tier scenario recreates the MMGL → MMMX route — a 276-nautical-mile flight from Guadalajara (5,016 ft elevation) to Mexico City (7,316 ft elevation) at FL370. The pilot manages high-altitude performance calculations at both ends, executes a "descend via" STAR with rigid step-down altitude constraints, sequences into dense inbound traffic, and flies an approach into a basin ringed by Popocatépetl (17,802 ft) and Iztaccíhuatl (17,159 ft). At 7,316 ft, true airspeed is approximately 15% higher than at sea level for any given indicated airspeed, producing faster ground speeds, longer landing rolls, and reduced go-around climb performance.
System intent: Dense traffic into terrain-ringed high-elevation basin.
What you'll practice:
- High-altitude performance calculations for departure at 5,016 ft and arrival at 7,316 ft, including density altitude corrections and TAS adjustments (FAA-H-8083-25C, Ch 11 — Aircraft Performance)
- "Descend via" STAR execution with rigid altitude constraints at each step-down fix, maintaining within 200 ft of published restrictions (FAA-H-8083-15B, Ch 10 — IFR Flight)
- Approach speed and energy management at a high-elevation airport where indicated speeds produce 15% higher true airspeeds and longer landing rolls (FAA-H-8083-25C, Ch 11 — Aircraft Performance)
- Terrain awareness during approach into the Valley of Mexico basin, with volcanic terrain exceeding 17,000 ft on multiple sides (FAA-H-8083-15B, Ch 10 — IFR Flight)
- VNAV for STAR altitude constraints to meet each crossing restriction without overshooting or undershooting (FAA-H-8083-15B, Ch 7 — National Airspace System)
- International IFR clearance procedures, including non-US phraseology, QNH in hectopascals, and metric altitude references (FAA-H-8083-15B, Ch 10 — IFR Flight)
- Top-of-descent planning on a short 276 nm route where cruise time at FL370 is minimal and descent must begin within minutes of reaching cruise altitude (FAA-H-8083-15B, Ch 6 — Departure)
- Terrain-critical missed approach procedure that ensures obstacle clearance in a basin surrounded by 17,000 ft volcanos (FAA-H-8083-16B, Ch 4 — Instrument Approaches)
What you'll walk away with:
- Confidence managing high-altitude performance calculations and approach energy at airports above 5,000 ft elevation
- Proficiency flying rigid "descend via" STARs with multiple step-down altitude constraints in dense traffic
- A terrain-awareness framework for operating in basins ringed by terrain that limits missed approach options

- S-MK2-W-1.0-01 — Airport operations knowledge (1 Master Knowledge credit).
How this Activity satisfies each syllabus:
S-MF1-W-1.0-01 (Operating on/around airports): The pilot performs high-altitude performance calculations for departure at MMGL (5,016 ft, density altitude ~7,400 ft) and arrival at MMMX (7,316 ft, density altitude ~9,100 ft). The approach into Mexico City requires managing a 15% TAS increase over indicated airspeed, producing longer landing rolls and reduced go-around climb performance. The missed approach procedure routes through a terrain-ringed basin with volcanic obstacles exceeding 17,000 ft on multiple sides. These tasks satisfy the Master-level requirement for operating in complex airport environments (FAA-H-8083-15B, Ch 10; FAA-H-8083-25C, Ch 11; FAA-H-8083-25C, Ch 14 — Airport Operations).
S-MF2-W-1.0-01 (Flight operations away from airports): The 276 nm route at FL370 requires the pilot to execute a "descend via" STAR with rigid step-down altitude constraints, manage top-of-descent planning on a compressed route, navigate international airspace with non-US ATC phraseology, and maintain terrain awareness during descent through step-down fixes with rising terrain on both sides. The pilot uses VNAV to meet each crossing restriction and manages descent rate calculations in real time when ATC amends restrictions (FAA-H-8083-15B, Ch 6, 7, 10; FAA-H-8083-16B, Ch 1, 2, 3).
S-MK2-W-1.0-01 (Airport operations knowledge): The pilot demonstrates knowledge of density altitude effects on aircraft performance at high-elevation airports, including takeoff distance corrections, approach speed adjustments, and landing distance computation. The scenario tests understanding of international airport procedures (ICAO phraseology, QNH in hectopascals, transition altitude differences), volcanic terrain constraints on approach and missed approach procedures, and the relationship between field elevation and go-around climb performance (FAA-H-8083-25C, Ch 11, 14; FAA-H-8083-16B, Ch 4).
Completion Standard: All tasks performed to Instrument Rating ACS (FAA-S-ACS-8C) standards.
