N508UP

This entry covers airframe tail number N508UP, a 2005-built Cessna 560XL Citation Excel / Citation XLS with serial number 560-5546. The aircraft is registered in the US and is owned by WHEELS UP PARTNERS LLC of New York, NY, US, the listed operator and base for routine operations. No other ownership transfers or notable registry actions are published in the provided data. Condition and valuation details are not published in the supplied dataset.

The cabin on N508UP is a single-zone executive configuration featuring a forward two-place divan, a four-place club arrangement in the center, and two forward-facing seats aft, complemented by a forward galley and an aft enclosed lavatory; baggage capacity is approximately 90 cu ft. Avionics and mission systems installed on this airframe include Honeywell Primus 1000 EFIS, Universal UNS-1Csp FMS with WAAS/LPV, Honeywell RNZ-850 navigation, TCAS II, Honeywell EGPWS, L3Harris SSCVR, and an ATG-5000 WiFi system. Typical mission profiles supported by the aircraft's performance and fit include medium-range business travel and charter operations from its New York base, enabling high-speed transcontinental legs within the listed 1,847 nm range and maximum cruising speeds around 429 kts. Maintenance considerations for this specific airframe would center on upkeep of the PW545 engines and the installed avionics suite, including WAAS/LPV and connectivity equipment.

The airframe belongs to the Cessna 560XL Citation Excel / XLS family, a mid-size business jet niche offering a balance of cabin comfort for up to 8 passengers, transcontinental-ish range, and performance to FL45,000. The combination of Pratt & Whitney Canada PW545 powerplants and Honeywell avionics provides a typical platform for owner-operators and charter companies demanding speed and flexibility for regional to coast-to-coast missions. Resale and maintenance considerations for this model emphasize engine cycles on the PW545 series, avionics upgrades such as WAAS/LPV compliance, and the value added by installed connectivity options like ATG-5000.
