What is Endorsement (PHM) in Aviation? This is a relevant question for pilots, instructors, and aviation professionals involved in pilot training and certification. The abbreviation ENDO refers to this specific type of endorsement associated with Pilot Helicopter Multi-Engine (PHM) operations. Understanding Endorsement (PHM) is crucial for anyone seeking to operate twin-engine helicopters or work within regulatory frameworks that govern such flight activities.

Overview of Endorsement (PHM) in Aviation
Endorsement (PHM) in Aviation refers to the formal authorization added to a pilot’s certificate or logbook that confirms the pilot has completed the required training and testing to operate a multi-engine helicopter. The PHM endorsement is distinct from general pilot endorsements because it specifically applies to helicopters equipped with more than one engine, which present unique handling and safety considerations.
Regulatory bodies like the FAA require that pilots demonstrate proficiency in managing critical aspects of multi-engine helicopter flight, such as engine failure procedures, performance evaluations, and emergency handling techniques, before receiving the Endorsement (PHM). The ENDO signifies that a pilot meets these qualifications and can safely operate a multi-engine helicopter under various flight conditions.
Endorsement (PHM) Training Requirements
The training requirements for the Endorsement (PHM) include a combination of ground school and flight training geared toward handling the complexities of multi-engine helicopters. According to FAA guidelines, pilots must undergo at least 10 hours of flight training in the specific make and model of the helicopter to be endorsed. This includes simulated or actual engine failure procedures to prepare pilots for realistic scenarios.
Furthermore, pilots need to complete a minimum of 3 hours of ground training covering aerodynamic principles, powerplant systems of multi-engine helicopters, and emergency protocols. Some helicopter models used in multi-engine configurations have maximum takeoff weights exceeding 7,000 pounds and require specific knowledge about engine torque management and center of gravity calculations. The completion of a practical test or check ride with an authorized flight examiner is also mandatory to demonstrate competence.
The Importance of Endorsement (PHM) in Aviation Safety
Safety is paramount in aviation, especially in the operation of multi-engine helicopters where unilateral engine failure can pose significant risks. Endorsement (PHM) ensures that pilots possess the skills to maintain control and safely land even in adverse conditions such as single-engine operation scenarios. Helicopters like the Bell 412 and Sikorsky S-76, which have two engines producing combined horsepower in excess of 2,500 HP, require pilots with specialized training to handle their complex systems effectively.
Endorsement (PHM) is also critical for commercial operators or emergency services teams using multi-engine helicopters for medical evacuations, search and rescue missions, or offshore transport. According to [FAA Advisory Circular 61-138](https://www.faa.gov/regulations_policies/advisory_circulars/index.cfm/go/document.information/documentID/1024689), obtaining the PHM endorsement reduces the risk of accidents related to mismanagement of engine failure or improper handling under high workload conditions. It directly contributes to a pilot’s ability to ensure passenger and crew safety while complying with regulatory standards.
How to Obtain the Endorsement (PHM)
Obtaining the Endorsement (PHM) requires completion of a structured training program, demonstration of proficiency in complex flight maneuvers, and understanding of multi-engine systems. Pilots usually start by enrolling in a certified training syllabus tailored to the helicopter type. This syllabus typically consists of:
- Ground instruction covering helicopter multi-engine aerodynamics and systems
- Flight hours focused on engine failure simulations and emergency procedures
- Performance calculations for takeoff, cruise, and landing with one engine inoperative
After completing these steps, the pilot undergoes a practical test administered by a Flight Instructor or FAA Designated Examiner. Passing this check ride confirms that the pilot can safely and competently operate a multi-engine helicopter. Once successful, the ENDO is logged either in the pilot’s logbook or certification documents, authorizing multi-engine helicopter operation.
Endorsement (PHM) and Its Role in Career Advancement
For pilots seeking to advance their careers in rotary-wing aviation, the Endorsement (PHM) represents a key milestone. Many commercial and offshore helicopter operators require multi-engine qualification to employ pilots, especially in sectors involving rigorous safety standards. Having the PHM endorsement increases employability and opens opportunities for positions in search and rescue, offshore oil rig support, and VIP transport.
Beyond commercial roles, the ENDO is frequently required for instructing pilots who wish to teach multi-engine helicopter operations. This endorsement signifies a high level of expertise and responsibility, making it indispensable for pilots aiming for specialized and high-profile roles. The investment in training and certification is therefore not just a regulatory hurdle but a strategic career move within the aviation industry.
