The high of the main rotor is lower than on the other competive models. The damped tripple wheel gear with its 2 lateral buckling axis brings the pivoted rotorblades additionally near the ground. Have you ever seen a A-109 in the mountains? Take your head down! The shutdown time is absolutely unimportant for a tail rotor strike
If you comes to ground on final or touchdown you will have a tailrotor strike or not. Tail rotor strikes on the ground within the cooling time are very rare...
I know personally 2 A109 Power with more than a single tailboom change or high maintenance action. The visibly signs of the tailboom vibrations are the common change of the pos lights.
the 109 has a seperate baggage area in the tail boom.
Nobody needs in HEMS seperate baggage areas. You need all the equipment within the flight and easy to get with a single grip from you seat! Thats also a big problem on the AS 350/355 or 206/407 series. Or will you ever land to get the needed?
To the speed, adopted a A109 with a cruising speed of 150kt and a BK 117 with 125kt (both VNE's are higher) the A109 get an advantage of 2,4 min on a 30 miles distance. Thats the usually distance in Europe.
Please understand me right, i'm interested in the new ship, but thats my observations... Obervations also Agusta could made, but i know the development of a complete new ship like the 900 / 135 is really expensive. The "power" is one of the best hot'n high twin, but the market needs also some other things.
