the big strip of grass on top, seems nice to land but not sure the A/C could glide till there with engine off (i dont remember the exact mark on this A/C for 1 angle of gliding, but the big strip seems away from it, refer to image here below)
I will choose to land on n the small strip of grass above the highway. But highway is not so bad idea if there is not too much traffic;)
Plane is over 5k in altitude. Reaching that grass strip will be a piece of cake. Plenty long enough for that particular plane which looks like a 172, even if he has to land downwind. The students biggest challenge will be getting the plane slowed down enough to land if he heads directly to the strip. He's only about two miles from it. Looking at the shadows, you are facing South. Lots of green means summer(ish) chances are good the wind will be correct for a decent landing. Grass strip is too perfect to be random. It's an airport. Right width, right length. If he crabs the plane, he'll be able to lose the altitude without gaining speed, and should be able to touch down safely within 10 minutes of losing his engine. I agree with Serge about using the hiway as a last resort. Serge, the hand spacer is a good idea in concept, however, with more females getting behind the stick, their hands are generally smaller than males, so it can throw the unexperienced pilot a false sense of security. My older instructor told me that being inexperienced, you wouldn't necessarily be thinking abstractly. His answer? "Fly the damn plane. Then work on a solution."
Welcome back Angie! You were missed. Hope all is better for you and your family.
