Primary Intelligence Question

What are the critical financial and operational distinctions between FAA Part 135 dry lease and wet lease arrangements, as defined by the brief’s cost benchmarks, regulatory requirements, and dispatch execution standards?

Key Intelligence

The brief outlines that FAA Part 135 dry lease and wet lease arrangements differ primarily in financial exposure and operational control, with base charter rates ranging from $2,000 to $20,000+ per billable hour depending on aircraft category (light turboprops to ultra-long-range jets). Dry lease operators bear FBO ground handling fees ($200–$2,500+ per arrival), federal excise tax (7.5% domestic U.S.), and terminal logistics costs (e.g., slot allocations at high-density airports like LCY, FAB, LSGG, or TEB). Wet lease arrangements—while not explicitly detailed—imply bundled services (e.g., crew, maintenance) that reduce upfront financial variability but require pre-flight audits of operator safety ratings (Argus/Wyvern, Part 135/EASA CAT) and itemized invoice verification to align with pre-flight estimates. Dispatch execution relies on real-time algorithmic routing tools to mitigate intermediary markups.

Direct Operating & Commercial Cost Analysis

Evaluating full mission expenses requires detailed visibility into hourly rates, regulatory fees, and ground handling:

• Base Charter Rates: $2,000 – $20,000+ per billable flight hour (by category)
• Federal Excise Tax (FET) / VAT: 7.5% domestic US FET or localized European VAT exemptions
• FBO Ground Handling & Ramp Charges: $200 – $2,500+ per arrival (waived with minimum fuel burn)

Regulatory & Terminal Logistics

Achieving seamless execution involves auditing critical mission variables prior to departure:

• Slot & Handling Allocations: High-density airports (e.g., LCY, FAB, LSGG, TEB) enforce mandatory landing slots and strict ground handling windows.
• Permits & Customs Clearance: International routing requires Advance Passenger Information System (APIS) filings and overflight permit approvals.
• Fuel Surcharges & Deicing Reserves: Winter itineraries or remote FBO stops require advance budgeting for Type I/IV glycol application and peak fuel adjustments.
