Yes, helicopter pilots can use a relief tube, urinal, or collection bag in flight when the equipment and procedure are compatible with the aircraft and operation. In the United States, the FAA does not publish a blanket rule that either approves one universal urinal or bans all in-flight relief devices. The controlling questions are whether the pilot can keep the aircraft under control, avoid distraction, follow the operator’s procedures, preserve emergency egress, and prevent careless or reckless operation.
That makes the answer operational rather than simply anatomical. A device used on a long military mission may be integrated, tested, and assigned to the aircraft. A generic bag bought for personal use has no automatic approval merely because it fits inside a helicopter.

What the FAA rules actually require
Two U.S. rules frame the legal answer. Neither one names a universal helicopter relief tube, but both can prohibit using one in an unsafe way.

Part 91: no careless or reckless operation
14 CFR 91.13 prohibits operating an aircraft in a careless or reckless manner that endangers the life or property of another person. A pilot who leaves the controls, blocks a control, creates a spill, or becomes so distracted that aircraft control suffers could violate this rule, regardless of whether the device itself is commercially available.

Part 135: duties during critical phases
For commuter and on-demand operations conducted under Part 135, 14 CFR 135.100 restricts duties and activities that are not required for safe operation or that could distract a crewmember during a critical phase of flight. The rule’s critical phases include taxi, takeoff, landing, and other operations below 10,000 feet above mean sea level, except cruise flight.
In practical terms, a crew may not treat a bathroom break as an entitlement during a busy approach, hover, confined-area operation, or other high-workload segment. Even if a relief system is installed, the pilot must defer its use whenever the operation demands uninterrupted attention. The exact application depends on the certificate holder’s manuals, crew procedures, and the circumstances of the flight.
No universal FAA approval label
FAA helicopter guidance emphasizes aircraft-specific equipment, operating procedures, and pilot responsibilities. It also points operators toward minimum-equipment-list procedures when equipment is inoperative. That framework does not create a single FAA approval standard that automatically covers every urinary-relief device in every helicopter.

Installation, wiring, plumbing, restraint, electrical load, cleaning, and emergency procedures can all matter. A loose accessory in the cockpit is not equivalent to equipment documented in the aircraft’s configuration and operating information.

Do helicopter pilots actually use urinals or relief tubes?
Yes. Relief equipment is used or tested for missions in which landing solely for a bathroom break is impractical, unsafe, or tactically undesirable. Military helicopters are the clearest documented example because crews may spend many hours airborne and may have limited opportunities to land.
Army AIRUS flight tests in October 2026
The U.S. Army reported on October 8, 2026, that crews from the 101st Combat Aviation Brigade completed the first Army helicopter test flights of AIRION’s Advanced Inflight Relief Urination System, or AIRUS, on October 5–7, 2026. Testing covered Apache, Black Hawk, and Chinook helicopters.
The evaluation was broader than asking whether urine could be collected. Crews examined fit, human factors, in-flight relief, and emergency egress. Egress testing checked whether users of different body sizes could get out safely while wearing or using the system. That emphasis shows why a military relief system is treated as aircraft equipment requiring integration and escape testing, not as an automatically acceptable personal accessory.
AIRION founder and chief executive officer Colt Seman said the system was tested for integration into the Apache, Black Hawk, and Chinook. AH-64 Apache pilot Chief Warrant Officer 2 Collin McAllister contrasted the design with earlier equipment, describing those systems as bags with coagulant inside. Brigade lead dietitian Capt. Gena Baisa reported that pilots had told the team they “tactically dehydrate,” an indication of how strongly bathroom logistics can influence hydration decisions on long missions.

Air Force equipment for bladder relief
An Air Force Life Cycle Management Center report describes AMXDmax as a bladder-relief device that pumps urine into a collection bag. The report identifies urinary-relief devices as a major priority for female aircrew. It establishes the existence of specialized aircrew equipment, but it does not establish that AMXDmax is sold through general retail channels or approved for civilian helicopter use.
What kinds of systems exist?
Relief equipment ranges from simple disposable containers to aircraft-integrated systems. The important differences are containment, hands-free use, fit, emergency compatibility, and what the aircraft or operator has authorized.
| System type | How it works | Key advantages | Important limits |
|---|---|---|---|
| Absorbent or coagulant bag | The user directs urine into a bag containing absorbent material or coagulant. | Lightweight, simple, and potentially disposable. | Requires careful positioning; can leak, fill, or interfere with clothing and controls. A generic bag has no automatic aviation approval. |
| Bladder-relief device with pump | A wearable or fitted interface moves urine through tubing into a collection bag. | Can keep the user seated and reduce the need to handle an open container. | Requires correct fit, routing, cleaning or replacement, and a procedure that does not obstruct egress. |
| Aircraft-integrated relief system | Equipment is evaluated and installed as part of a particular aircraft or mission configuration. | Can address mounting, containment, crew workflow, and emergency procedures together. | Approval, maintenance, training, and configuration control are aircraft- and operator-specific. |
| Disposable male urinal bag with absorbent gel | A consumer-style bag uses a shaped opening and gel or absorbent material to contain urine. | Low cost and easy to carry as an emergency option. | It is a generic physical accessory, not proof of FAA approval, cockpit compatibility, or safe use in a particular helicopter. |
How a crew uses a relief system safely
There is no single procedure that applies to every helicopter. The following sequence describes the decisions an operator normally has to address; the aircraft flight manual, checklist, standard operating procedures, and training always take precedence.

Identify the expected mission duration, likely high-workload segments, crew positions, clothing, and the point at which relief may become necessary. Hydration planning should not rely on deliberate dehydration as a substitute for a safe bathroom procedure.
- Confirm authorization and configuration. Verify that the exact device is listed or otherwise accepted for the aircraft, mission, and operator. Check whether the equipment is installed, carried as loose equipment, or subject to a minimum-equipment-list or maintenance requirement.
- Fit and route the system on the ground. Position the interface, tubing, bag, or mounting so that flight controls, collective and cyclic movement, seat restraints, communications equipment, armor, and survival gear remain unobstructed. Check seals and connections before starting the engine.
- Choose a low-workload time. Do not begin during taxi, takeoff, landing, low-level maneuvering, hover work, formation tasks, emergencies, or any other period in which the pilot’s attention is needed. Part 135 crews must also respect the critical-phase restriction in 14 CFR 135.100.
- Coordinate with the other crewmember. In a crewed helicopter, the pilot handling the controls and the pilot using the system must maintain a clear division of duties. A single-pilot operation has a higher workload risk because there may be no second pilot to monitor instruments and flight path.
- Keep the controls and restraints clear. The user should remain seated and retain immediate access to required controls, restraints, communications, and emergency equipment. A system that requires standing, twisting out of the seat, or moving a control is unsuitable for that phase of flight.
- Secure and inspect after use. Close or isolate the collection bag, check for leaks, and restore clothing and equipment without rushing. Any spill, odor problem, skin-contact issue, or equipment malfunction should be handled under the operator’s hygiene and maintenance procedure.
- Preserve emergency egress. The user must be able to release restraints and exit through the required path. If tubing, straps, or a full bag can snag during evacuation, the system needs a documented quick-release or another approved method.
Why fit, anatomy, and egress are engineering issues
A relief device has to work with the human being and the cockpit, not just collect liquid. Flight clothing, body armor, harnesses, seat geometry, vibration, acceleration, and confined spaces can change the fit. A design that works for one body type may leak or become difficult to remove for another.

Female aircrew have historically had fewer simple options, which is why the Air Force report identifies urinary-relief devices as a major priority for women. Systems may use different interfaces for male and female anatomy, but no generic description can establish that a particular product will fit a particular pilot. Fit testing should include normal seated posture, harness tension, movement needed for controls, and the clothing worn on the mission.
Egress is equally important. A system can be comfortable in level cruise yet become dangerous if it catches on a restraint, blocks a door, or cannot be disconnected quickly after a hard landing. The Army’s AIRUS evaluation specifically included egress checks for users of different sizes, illustrating the level of human-factors review expected for serious aviation equipment.

A generic disposable male urinal bag with absorbent gel may be physically usable in some circumstances, but “can fit” is not the same as “is approved” or “is safe.” The bag must not leak, obstruct controls, compromise restraints, create an odor or contamination hazard, or prevent emergency evacuation. It also must be compatible with the pilot’s anatomy and clothing.

Manufacturers’ marketing language is not a substitute for aircraft documentation. Unless the aircraft or operator has evaluated the item, a pilot should treat a generic bag as an emergency personal accessory rather than as certified helicopter equipment.
Operational risks and failure modes
- Distraction: Opening, positioning, or troubleshooting a device can draw attention away from instruments, traffic, terrain, or the flight path.
- Leakage and contamination: A poor seal, overfilled bag, disconnected tube, or damaged absorbent liner can contaminate clothing, seats, controls, or survival equipment.
- Control interference: Tubing, straps, or a bag can snag the cyclic, collective, pedals, seat belt, or other cockpit equipment.
- Emergency evacuation: Equipment that cannot be released quickly can delay escape or become a snag hazard.
- Hygiene and skin health: Prolonged moisture, pressure, or contact with urine can cause irritation or infection risk, especially on long missions.
- Capacity and disposal: Collection volume, odor control, sealing, storage, and post-flight disposal must be planned. A system that works for one short flight may be inadequate for a longer sortie.
- False confidence: A product labeled for travel, camping, or medical use may not have been evaluated for vibration, acceleration, cockpit geometry, or aviation egress.
How civilian operators should decide
An operator evaluating a relief device should document the decision rather than leaving it to individual improvisation. The following checklist captures the main questions.
- Is the device authorized by the aircraft owner, operator, flight department, or certificate holder?
- Does the aircraft documentation address installation, carriage, electrical or plumbing connections, and maintenance?
- Can the pilot remain seated with unrestricted access to the controls and required instruments?
- Can the device be used only during an appropriate low-workload phase?
- Does the procedure comply with Part 135.100 when the operation is under Part 135?
- Can every intended user release the equipment and exit through the required emergency path?
- Has the system been checked for fit with actual flight clothing, harnesses, and survival gear?
- Are leak response, cleaning, disposal, replacement intervals, and spare equipment defined?
- Have pilots been trained to stop the procedure immediately if workload, weather, traffic, or aircraft status changes?
If any answer is unresolved, the conservative choice is to land when practical rather than improvise in flight. A planned landing may cost time, but it avoids turning a personal necessity into a control, contamination, or evacuation problem.

Military crews may face endurance, terrain, tactical, or security requirements that make landing difficult. Their relief equipment can therefore be part of a broader system involving mission planning, medical guidance, aircraft integration, crew training, maintenance, and egress testing. The Army’s 2026 AIRUS flights demonstrate that this capability is being evaluated as a formal aviation requirement.
A private owner, sightseeing operator, or small commercial company usually has a different risk profile and a different approval path. The fact that military crews test a system does not authorize the same device in a civilian aircraft. Conversely, the absence of a military-style system does not mean a civilian pilot is legally forbidden to use any relief device; it means the operator must establish that the equipment and procedure are safe and compliant.
Bottom line for pilots
Helicopter pilots are not categorically barred from urinating during flight, and real military programs show that specialized systems can make it possible. The legal and operational test is whether the activity is authorized for that aircraft and operator, performed outside prohibited high-workload phases, and completed without distraction, control interference, leakage, or loss of emergency egress.
Use the aircraft’s approved procedures and equipment. Treat an unapproved disposable bag as a last-resort accessory, not as an FAA-cleared cockpit system, and never let the need for relief override immediate aircraft control or evacuation requirements.
