La pause stratégique de l’AAM : Préparer le décollage
L’industrie aéronautique, y compris le secteur émergent de la mobilité aérienne innovatrice (AAM), connaît souvent un rythme plus lent pendant les mois d’été. Cette période de calme relatif est propice à la planification stratégique et à la mise en place des fondations, alors que l’industrie se prépare à une saison chargée.
Alors que les journées d’été s’installent, apportant une chaleur étouffante dans diverses parties du monde, il est important de se rappeler que parfois, le calme précède une tempête de progrès. L’industrie aéronautique, connue pour sa nature méthodique et délibérée, connaît souvent un rythme plus lent pendant cette saison. C’est particulièrement vrai pour le secteur émergent de la mobilité aérienne innovatrice (AAM), qui prend le temps d’élaborer des stratégies et de jeter les bases de sa réussite future.
Navigating The Dog Days of AAM Summer
The aviation industry, including the emerging Advanced Air Mobility (AAM) sector, often experiences a slower pace during the summer months. This period of relative calm allows for strategic planning and the laying of foundations, as the industry gears up for a busy season ahead.
As the dog days of summer settle in, bringing sweltering heat to various parts of the world, it’s important to remember that sometimes, calmness precedes a storm of progress. The aviation industry, known for its methodical and deliberate nature, often experiences a slower pace during this season. This is particularly true for the emerging Advanced Air Mobility (AAM) sector, which is taking the time to strategize and lay the groundwork for future success.
Preparing for AAM with eSTOLs, First Steps First
There are more solutions than obstacles, Nicolas Zart
If we’ve been fairly quiet the past few weeks it’s not for lack of wanting to educate and talk about advanced air mobility (AAM). It’s because we’ve been busy redefining a core strategy, as should be done often in any industry and business life.

AAM Will Happen, Not How We Thought it Would
There’s a fine line between keeping your strategy close to the heart and away from prying eyes, and then there comes a time when the white elephant needs to be addressed. While we’re bombarded with how electric vertical take-off and landing (eVTOL) will start to conquer the world ushering in an era of clean areal mobility, more and more reasoned voices question the viability of eVTOL. Don’t get us wrong. We’re 100% behind eVTOLs and we will see them fly. however, practicality dictates we must first access electric flight in the most efficient ways. Electric short take-off and landing (eSTOL) offer two irrefutable pros, their better energy usage and smaller vertiport approach footprint.
Why are we using helicopter executive
eSTOL’s Unbeatable TLOF & FATO
Essentially, eSTOLs have no transitions from vertical to horizontal flight. This not only maximizes their energy use but also means they have shallower FATOs and TLOFs. What are FATos and TLOFs? According to the US Federal Aviation Agency (FAA), the TLOF of a heliport is the touchdown and lift-off area surrounded by a final approach and takeoff area (FATO). The TLOF is a load-bearing, usually paved, area at a heliport (helipad) where the helicopter is permitted to land. The TLOF can be located at ground or rooftop level, or on an elevated structure. The TLOF is normally centered in the FATO and is the safety area provided for VTOL aircraft to touch down. Final Approach and Takeoff Area (FATO). The FATO is a defined heliport area over which the final approach to a
hover or a departure is made. The touchdown and lift-off area (TLOF) where the helicopter is permitted to land is normally centered in the FATO. A safety area is provided around the FATO.
The relationship of the TLOF to the FATO and the Safety Area is shown in Figure 3-2. A FATO may NOT contain more than one TLOF.

Why are we using helicopter terms? Because vertiports are defined using many heliport executive briefs since their operations are similar. Vertiports are essentially modernized heliports with one difference, not all heliports can become vertiports due to space and original design constraints.
From Helicopter to eVTOLs to eSTOLs
The second reason why eSTOLs will most likely take off first, pun intended is their fairly more conservative use of energy. Since eVTOL will need to use vertical lift before being wing-borne, they will consume more energy than winged aircraft, especially those with blow-lift designs such as the Electra. This energy discrepancy will tally up at the end of the year and shareholders and municipalities will these uncomfortable questions to vertiport owners and operators.
Essentially, a blow-wing eSTOL will blow air under its wings smoothly establishing enough airflow to retract its flaps and allow portance, whereas an eVTOL will need to fly up fast enough for enough flow under the wings to give it portance.
Electric Air Mobility Marches Forward with eSTOLs
After mulling over the practicality of eVTOL over eSTOL operations, it became apparent that eSTOLs can achieve shorter FATOs. We redesigned our vertipad concepts to capture eSTOL’s potential longest landing and found it would be no bigger than a small to medium-sized vertiport. The other benefit to this is we automatically added extra landing pads or vertipads on top of creating eSTOL ports.
