LIGHT TWIN FOR HOT AND HIGH ALTITUDE

Friends,

Amongst A109 Grand New, EC 135 P2e and Bell 429, which machine is best suited for high altitude flying i.e. landings at 10,000 ft PA with temperatures ranging upto + 20 deg Centigrade. Would appreciate if you could give the HOGE landing weight for the a/ mentioned altitude respectively.

It might be better to specify the payload to be moved (and radius of action required), and the country of registration - the 429 has a max weight of 7,500lbs approved in some countries, but not in other, as just one example.

Here you can find the two product spec books for the 429 depending on if your country has approved the the 7500 lbs MGW

Data & Brochures

It looks like the standard performance info is on page 4/5 and the performance charts are at the end.

I know that the OEM sales people typically have comparison charts though if you don't want to do it yourself.

Basically it will be a corporate machine in five seat configuration but for EC135 which will be in a four seat configuration . My country has approved the increase in AUW of 429 to 7500 lbs

ROA we are looking at is 220 NM, EEW of 429 is 4950 lbs, EC135 is 1960 kgs and A 109 G New is 2180 kgs. With these figures and landing at 11000' PA at +15 deg C, what payloads can be carried ?
