[Titanaircraft] Re: Fly the airplane

Hi Jim:

Excellent comments.

I have also experienced a few engine outs, with two of them on takeoff (you only need to experience one to become fanatical about learning what needs to be done to survive). As a result of these experiences, I have also spent a great deal of time experimenting with and practicing for "engine out".

Your admonition that one needs to KNOW what altitude is required to successfully complete a "return to the landing strip" is spot on. I have also found, through much experimentation, that if one decides to do this, "nose down hard, and turn hard" provides the lowest expenditure of both time and altitude.

Like you, I think that 600 feet of altitude is the bare minimum requirement in a Titan Tornado, and that this manoevre should be attempted only after one has acquired a great deal of practice.

At this end, I also push the view that one should mentally divide the takeoff sequence into specific segments.
- KNOW how many feet you will consume to get airborne in various density altitude conditions.
-KNOW the approximate altitude at your home airport at which you can push the stick forward and safely land on the remaining runway or over-run.... for EACH runway.
- KNOW where the safest off-airport landing area is for each runway at your home airport until you reach 600 feet (must be more or less straight ahead)
- Practice, "nose down hard, turn hard" returns to the runway until you are completely comfortable with the manoevre (lots of practice at altitude first!)
- Practice "engine out" simulations from all points of the pattern, for each runway at your home base ("Nose down hard, turn hard" still applies).
- While flying cross country, at all times, KNOW where you would head if the engine gets quiet.

Yes, the above-noted points might sound a bit "hard-nosed" to some.... until you have a real engine out.

Best,
Larry
