The quest for “runway independence” continues to evolve. Previously I posted an article that discussed C130 variants use as seaplanes. What if the aircraft had the capacity to move larger volumes of freight, further distances like a C17 for less cost…AND land on water? DARPA's Liberty Lifter project aims to create such a seaplane. Indeed, this could add agility and increase distribution.

How well do you know your Aircraft engine parts?

I recently had the chance to fly on both the EMB E2 with GTF1900 engines and the A220 with GTF 1500. The feedback I received from pilots was quite insightful. On the EMB E2 with GTF1900 engines, pilots were very positive about the fuel consumption and noise levels. However, on the A220, pilots mentioned that while fuel savings were significant, but the noise level was not as quiet as anticipated. It's worth noting that the GTF engines 1500 and 1900 are nearly identical, with only minor differences. Having integrated them, I can comment as such. Various factors contribute to cabin noise levels, impacting the overall flying experience. I wanted to share this observation as an interesting insight into performance differences for those interested in the aviation industry.

HAVE YOU HEARD OF THE V1 STATEMENT SHORTLY BEFORE TAKEOFF? V1 is the maximum speed during the takeoff roll at which the pilot can take the first action to abandon the takeoff and stop the aircraft. It represents the point of no return, beyond which it becomes unsafe to stop the aircraft on the remaining runway. If an engine failure or other serious malfunction occurs before V1, the pilot must immediately reject the takeoff and bring the aircraft to a stop. However, if the failure occurs at or after V1, the takeoff must be continued. The precise value of V1 is calculated prior to each takeoff based on factors such as aircraft weight, runway length, altitude, temperature, wind, and engine thrust. It is the minimum speed at which the aircraft can safely take off and climb to a safe altitude with one engine inoperative. Stopping the aircraft within the confines of the runway or safely continuing the takeoff is predicated on an appropriate and timely stop/go decision at V1. The V1 call should be made such that the call is complete just as the speed is achieved. #aviation #aviationlovers

The wing tips of an aircraft are vital elements that significantly impact its performance and safety. They enhance aerodynamic efficiency, minimize drag, and bolster overall stability. When you need high-quality wing tips, turn to 5AERO. ✈️ In the event of unexpected challenges, such as adverse weather conditions or sudden changes in airflow, wing tips provide an extra layer of protection and confidence. They're the unsung heroes of aviation, quietly ensuring your safety and comfort with every mile flown. We offer an extensive range sourced from top manufacturers, catering to various general aviation aircraft. Whether you're a pilot or a mechanic, count on 5AERO to deliver aircraft wing tips at competitive prices. 💸 Elevate your flying experience and reach new heights with our top-notch wing tips and components.

Finished some very interesting pre-testing measurements in the A320 fuselage in the acoustics climate chamber at cabin and cabin systems lab (Gordon Konieczny) at HCAT, Hamburg Center of Aviation Training with some of our LuFo project Team Ashish Chodvadiya and Martin Knorr. Some measurements were done with equipment and expertise of my colleague Kay Kochan. Also thank you to Martin Engelke and Jörg Sprengel for letting us test an IMV CORPORATION K2 for this rather special application of acoustic excitation. We tried and so far partially succeded in replicating a measured in flight cabin acoustic spectrum with an excitation of a nominal 14kWpeak acoustic power. And beliefe or not, basically we need more power... Switch on the sound and listen to the result so far. Further improvements and many more flight situations to come... The project will use that data to have a realistic excitation level to determine dominant acoustic power pathes and characterize them. With this, lighter and better nice reduction can now be developped and measured under realistic excitation in the lab. This will be particularly challenging for more efficient future aircraft propulsion systems with potentially louder sound radiation. Fahrzeugtechnik und Flugzeugbau @ HAW Hamburg

This is how we load an aircraft engines into the Maindeck.

Difference between ETOPS and EDTO? We hear two common terms ETOPS & EDTO when an aircraft flying with one engine inoperative, let's check the basics. ETOPS (Extended-Range Twin-Engine Operations): - allows modern twin-engine aircraft to operate efficiently over long distances, even when diversion airports are limited or non-existent. - Purpose: When one engine fails on a twin-engine a/c, ETOPS helps predict & manage how far & at what speed the aircraft can travel on one engine. The goal is to reach an adequate airport for landing. - Threshold Time: for all turbine-engine aircraft is 60 mins of one-engine-inoperative cruise speed. Beyond this, additional time is needed to fly to a suitable airfield with only one engine. - Aircraft with only two engines to take advantage of ETOPS - Approval: ETOPS flights require approval from both the aircraft type & the airline operator. Dispatchers and controllers must be trained and approved for EDTO operations. EDTO (Extended Diversion Time Operations): - Transition: ETOPS is now EDTO but with some modifications. The main change is that it distinguishes between operations that do not exceed an established “Threshold Time” and those that require EDTO approval. - Threshold Time Definition: The “Threshold Time” is the range established by the state of the operator to an en-route alternative aerodrome. Any time beyond this threshold requires EDTO approval from that state. Calculation: EDTO calculates one-engine flying time in standard atmospheric conditions (ISA) and still air to convert threshold time to distance. Approval: Both the aircraft type & the airline operator must receive EDTO approval. Flight operations staff (dispatchers or controllers) must be trained and approved for EDTO operations. In summary, while we may still find ourselves saying “ETOPS,” the regulations we comply with are now the new EDTO ones. Both ETOPS and EDTO ensure the safety of twin-engine aircraft during extended flights, allowing them to traverse vast areas of the world with confidence. 🛫✈️

Sometimes, a small proceduere change can result in large savings for the airline companies. For those off you not familiar with turboprop operations, here is a short description of the engine start procedure: 1. Start one engine. It will run in feather (low RPM). Time: 30 sec. 2. Set the propeller control to AUTO or 100% (depending on engine variant). The propeller RPM will increase. Time: 30 sec. 3. Repeat for the other engine. Starting both engines this way takes 2 minutes. This is how most pilots learn to start the engines, but by alterning the procedure, time and fuel is saved. https://lnkd.in/gAqsyMUk
