Jesus wept - Stop way/clear way/accelerate stop/accelerate go/TODR/LDR

The thread starter is asking about a potential private operation off a private strip - not running a RPT operation

I always found the baron a beast on the takeoff but required a lot of runway to land as she was a slippery little bugger.
I once watched a 'pilot' barely stop a B58 on 11L at ysbk in light rain - because he was landing too fast - a VERY common practice. Land a Baron at 1.3 Vs for your actual weight and they can be landed very short indeed. When you get very comfortable in the aircraft 1.2 Vs is even better.

Vso (MAUW) in a B58 is 74kts. At typical landing weights its more like 68-70kts. Vref of 84-91kts works well. 100-110 kts + does not.

LDR is from 50' to stopped. TODR is from brakes release to 50'. Ignoring for a moment that these are certification numbers that bare little resemblance to real life neither of those 'points in space' need to be/should be/are required to be over the runway.

Neither a road, nor a gorge are suitable as a clearway
What?

Clearway.

A defined area at the end of the take-off run available on the ground or water under the control of the aerodrome operator, selected or prepared as a suitable area over which an aeroplane may make a portion of its initial climb to a specified height.
Specified Height = 50'.

The thread starter has a TORA/ASDA of 710m. Un-factored TORR for a B58 at MAUW is 425m and about 434m for landing run - ISA MSL of course. He has stated that there are no obstacles in the approach or departure paths.

Call it 440m for both - x 1.60 = 704m.

Anyone going to suggest that factoring by 60% is less than conservative?

The only thing the thread starter needs to search his soul about is whether he can,

1/. REALLY afford the care and feeding of a Baron and,

2/. Is he up to flying the aircraft correctly and precisely.

NOT whether the proposed airstrip is long enough.
