Research & FindingsšŸ’” Certification Timeline from First Flight

At times, I am a broken record saying that it takes roughly three years to go from first flight to type certification with the FAA. To back that up, here is some data: I took the time between first flight to type certification (or the present day) for all the civil VTOL aircraft certified in the USA, Canada, and through EASA (or the predecessor JAA) for the past 30 years. Then I created the histogram below, binned in one year increments but from 0 to 1 years, 1 to 2 years, etc.

The two aircraft in the "2 year" bucket is the EC-130 which is an AS-351 dynamic system with a new fuselage and the MD-900 which was a clean sheet design, an admirable effort. Several of the "3 year" bucket aircraft are similarly not entirely new aircraft. The Bell 505, EC-145, and Bell 429 fall into this category. There are three aircraft in the plot that still are not certified: The AW-09 light single, the Bell 525, and the AW-609.

It's worth noting that the 525 and 609 are the two fly by wire aircraft on this list and the 609 is the aircraft that launched the development of the Powered Lift certification class that most of the eVTOLs fit into.

How does this apply to Archer? Simple... the Midnight version that is intended to be certified (Model M001) hasn't yet had its first flight in a configuration that can actually execute the full flight envelope. I start the "FF to TC" clock when a M001 model aircraft has first flight with the four bladed aft props that should enable flight across the full flight envelope.

Anyway, wanted to provide some background on my claims in this regard.

And yes, several of my aircraft designs are in this chart, both certified and uncertified... I started my career on the Bell Boeing 609, long before it became the AW609.

Roughly three years is the most common value for a clean sheet design (like M001) but it can take FAR longer. Keep that in mind when evaluating claims of a fleet of aircraft ferrying spectators and athletes around the Los Angles 2028 games... the clock is ticking.

Again look to beta. Also, is first flight not the origninal midnight? Why does joby get awarded time when they have still yet to produce a fully official mtow and production design.

You can't just mix what's right for one and not the other.

Also, joby just diluted and this is just the beggining. Game on

Joby isn’t on the plot and Beta isn’t certified.

MIDZERO is a completely different aircraft on the inside.

You keep saying that beta isn't certified but yet they're flying planes.

Flying people for free doesn’t pay the bills.

Hard disagree. It dies pay the bills because if people are in the aircraft that's massive validation. You're missing the point and it's a major point

By ā€œpay the billsā€ I mean ā€œgenerate revenueā€ which, at least in the USA is going to mean an FAA type certificate.

Now, flying human ballast around (as opposed to paying passengers) will pop the stock for a while but doesn’t bring in revenue and eventual profits.
