The pop-out floats on helicopters are primarily designed to keep the helicopter upright to give the crew and passengers enough time to safely egress the aircraft after a successful ditching. Seeing a roughly 15 million dollar helicopter keep its flotation gear inflated and getting towed ashore like a dingy...

Helicopters operating in and around major airports is very common. In the United States, the FAA publishes prescribed routes and altitudes for helicopters in 8 major cities across the United States, I have flown almost all the routes in a helicopter mostly at night in over 7 of the 8 cities (8th one being D.C.) Here is the route PAT25 was flying last night, it’s called Route 4 over the Potomac River. These routes have been in place for many years and particularly in DC, they are vital for the police, military, and national security to circumnavigate the Ronald Reagan Washington National Airport safely 24/7. You are operating a complex aircraft in a complex environment and you can get task saturated even with a two pilot crew like PAT25. Task saturation also can happen to the most experienced air traffic controller. To give you an example, ATC may call out traffic to you and you confirm that you have it insight or maybe you spot the wrong aircraft. It takes one little thing to happen to lose sight of that traffic in question, e.g. a light flashes on your instrument panel, the person sitting next to you or behind you asks a question, you have multiple radios that you are listening to, you spot a bird, and the list goes on and on. There are so many questions that will probably never get answered like, were both of the pilots wearing Night Vision Goggles (which give you around a 40° field of view), did they identify the correct aircraft that they assured ATC they had insight and will maintain visual separation with, how many other aircraft was the controller trying to keep separated, why didn’t the controller inform the CRJ about the helicopter? It’s a mind boggling amount of data to digest even for a pilot or controller with thousands of hours of experience. The reality is, this is a very tragic and horrible aviation accident that will hopefully invoke some kind of change to prevent this type of disaster from ever happening again. I believe given the high visibility of this accident happening in the Nation’s Capital will lead to changes. What those changes might be, who knows yet. Either this route 4 over the Potomac is going to get changed or landings to runway 33 at Reagan will no longer be authorized. This is the human element in aviation, we’re still discussing accidents that took place about 100 years ago and it’s important to discuss these accidents because you want to remember them and hopefully learn from them and not repeat the same mistakes twice.

Today, at the invitation of aircraft manufacturing giants, Airbus, I led a high-level delegation to its headquarters in Toulouse, France. At the occasion, on behalf of the Federal Republic of Nigeria, I signed a Working Together Agreement with the company. Highlights of the agreement are as follows: •Fleet Expansion: Leveraging the successful integration of the Airbus A220 (as seen with Ibom Air), to establish Nigeria as a leader in regional and continental flight operations. •Infrastructure & Technical Support: Airbus will provide comprehensive consulting for Maintenance, Repair, and Overhaul (MRO) facilities, flight operations, and aviation market insights. •Human Capital Development: Creating high-value jobs for the next generation of Nigerian talents through specialized training programs for pilots, engineers, and cabin crew. •Market Leadership: Aligning with Airbus’ Global Market Forecast, which predicts a demand for 1,490 new aircraft in Africa over the next two decades. Nigeria aims to capture a dominant share of this growth by utilizing its geographic advantage as a global bridge. The visit concluded with a commitment to further technical exchanges, including upcoming inspections of Airbus’ Defence & Space and Helicopter divisions. The delegation included members of the Airline Operators of Nigeria (AON) and key industry stakeholders (all of whom attended at their own expense).

Absolutely wild footage, this is a real world engine failure in a MD500 (Think Magnum P.I. helicopter) over Kauai, Hawaii out on a tour flight. You’ll probably have to watch this a few times but the video starts out with the helicopter under power and then the engine sound goes silent. The beeping you hear is the engine-out audio beep to inform the pilot that engine power has been lost. This maneuver that pilot is doing is called a Autorotation and the way to think about helicopter flight, the engine is turning this big fan (rotor blades) on top of the body and sucking in air from the top and projecting it downward to overcome the force of gravity. When engine power is lost, you experience a reverse in airflow because now gravity takes over and the air flow is coming from the bottom of the main rotor disk. The only thing the pilot can really do is to make sure the rotors keep spinning by changing the pitch of the rotor blades through the use of the “collective” which is a lever next to the pilot’s left leg and it only moves up and down. The pilot has to manipulate the collective during an auto rotation to make sure the blades keep spinning. If the pilot pulls up too much on the collective, the rotor blades will bite too much of air causing a resistance and slow the rotors down. If the pilot doesn’t pull enough collective.. the blades will speed up and potentially cause a catastrophic failure. The other control the pilot has is called the cyclic. This cyclic sits between the pilots legs and and manipulates individual pitch of the rotor blades to tilt the rotor disk aka “big fan” and make the helicopter go forward, backwards, left, right. So essentially in this type of emergency, you have to manipulate the controls in a delicate balance because no matter what, gravity is taking you to the ground because the engine is no longer producing power. The pilot did an outstanding job here given the geography and limited amount of flat terrain to put the helicopter on the ground. Thankfully it sounds like no souls were lost and only one injury according to a news report (see the link below)👇 Of course there is a lot more to helicopter aerodynamics but I’m trying my best to put this in simpler to digest terms. Big thanks to Combat Learjet for sharing and definitely worth a follow!
