N4625B Aircraft Overview
Performance Profile
Turboprop performance from N4625B: 186 knots, 1,070 NM, and 25,000-foot ceiling. The Cessna Caravan 208B's 1x Pratt & Whitney Canada PT6A-114A burn significantly less fuel per hour than jet alternatives, which is the category's defining advantage.
Mission Profile
N4625B handles the missions where turboprop economics make sense: short legs, unpaved or short runways, and routing to airports that jets cannot reach. The Cessna Caravan 208B's 14-seat cabin and 1,070 NM range cover these missions efficiently.
Charter Authorization
N4625B holds Part 135 authorization. Turboprop charter rates are the most accessible in private aviation. Reach out to discuss this aircraft or alternatives.
Insider Note
One detail worth noting: the Cessna Caravan 208B's single-engine variants (if applicable) carry higher insurance costs but lower acquisition and maintenance expenses. N4625B's configuration determines where it falls on this spectrum.
Charter & Acquisition Briefing
The helicopter bearing registration N4625B is held by MARTINAIRE AVIATION LLC. Helicopters provide direct-to-destination service that eliminates the need for airports entirely.
Fleet Position
Over 10,000 helicopters are on active U.S. registrations. FAA data shows N4625B based in ADDISON, TX. The U.S. helicopter fleet serves EMS, offshore oil and gas, law enforcement, utility, VIP transport, and flight training. Maintenance infrastructure is extensive, with turbine helicopter service available at most major airports.
Charter Availability
N4625B is Part 135 charter authorized. Helicopter charter rates range from $1,500 to $8,000 per flight hour depending on type and configuration. VIP helicopter charter serves urban transfers (Manhattan to JFK in 8 minutes), resort access, and event transportation where ground travel times exceed 2 hours.
Mission Profile
Optimized for missions where vertical takeoff and landing capability is essential. EMS programs save lives by reaching accident scenes and hospitals directly. Offshore operators service platforms hundreds of miles from shore. Law enforcement provides aerial surveillance that ground units cannot replicate.
When to Choose Something Else
Skip helicopters for routes over 200 nm. At 130 to 170 knots, helicopters take twice as long as light jets over 200+ mile routes. For distances exceeding 150 miles, a combination of helicopter transfer plus fixed-wing jet provides the fastest door-to-door time.
Ownership & Operations
Aircraft ownership in the United States falls under FAA registration requirements. Every U.S.-registered aircraft carries an N-number that links to public records including owner name, address, airworthiness date, and certificate type. The FAA Aircraft Registry maintains this data and updates it as aircraft change hands. Prospective buyers use these records to verify ownership history, lien status, and maintenance compliance before committing to an acquisition.
Pre-Purchase Considerations
Avionics modernization drives both capability and market value. Aircraft with legacy analog instruments trade at significant discounts to those with modern glass cockpits (Garmin G5000, Collins Pro Line Fusion, Honeywell Primus Epic). ADS-B Out compliance is now mandatory in U.S. controlled airspace. Buyers should factor avionics upgrade costs into their acquisition budget when evaluating older airframes.
Charter Market Context
Empty leg pricing offers 25 to 75% discounts on published charter rates. These opportunities arise when an aircraft needs to reposition from a drop-off point back to base or to the next pickup location. The tradeoff is schedule inflexibility: departure time, date, and route are fixed by the operator's existing itinerary. The Jet Finder maintains an empty leg alert system for frequent charter clients.
