We all know some pilots need automation and others can fly attitude and power using QRH. If the altimiter works, use it, if the attitude indicator works, use it, if automation works use it. Use what ever still works and any competent pilot will make it work. I wouldn't want to be on an aircraft with a pilot that had to have automation to fly his airplane.
Many here disagree with that but I have considered loss of all power in my B757 including battery power and with no eletrical power know I could navigate and land safely if I had visual reference to a horizon. Whiskey compass and clock with standby altimiter would navigate and standby airspeed and alternate gear and flaps would handle landing.
I even played around with the whiskey compass in the 757 heading southbound over Cuba just using the compass to keep wings level for fun and it works just like a J3 cub. With the lead error you will not bank if you hold a south heading. You don't even need an attitude indicator in the clouds with all dead electronics. I learned that as a student pilot in an Aeronca Champ with 3 hrs. Those aircraft had no battery so no automation and it worked just fine. Funny how some newer pilots depend on it but we never had it and didn't need it.
