@Hotel Mode:

Thats about the same we do for qualification, 2 flights/year required to maintain it.

BTW, which type are you flying into INN?

"...Don't even think about engine failure."

Hmmm, well in the B720...it would NOT make a difference!
Other types....could be a problem....maybe.

411a, all engine failure cases on either the approach or after V1 are catered for by company procedures which we practice in the sim every year. This is for a twin engine jet (Airbus and Boeing).

The largest aircraft I have seen at Innsbruck is the B767,
Where did the B720 come from?? :confused:

If my memory serves me right, this was "Montana air" in the late 70s / early 80s... but they've been out of business now for around 20 years.

I fly the 146 (RJ) hence the performance snags, although its not such a big deal to lose 1!

411A 10th Apr 2002 22:42

Yes indeed, for the 4 engine aeroplanes....no big deal.

Well well...

Comparing minimum required approach-climb and landing-climb performance of 2- and 4-engine airplanes with one engine out (thus 25% less thrust on a 146, but 50% on a 737) might require some additional considerations

According FAR 25 both airplanes need to demonstrate the SAME (3.2%) landing climb segment gradient (=balked landing), whereas on a missed approach, a 4-engine a/c should indeed have a better climb gradient (2.7% vs. 2.1%).

This means, that when catering for an engine failure during balked landing, procedure designers (and finally pilots) are faced with the same performance, regardless of the number of engines we have. During approach climb (missed approach) however, 4-engined a/c are about 28% better off.

For those interested in photos of INN go to the site of "Airliners.net".
