For some its a very stressful time being examined in the box; far more so than any line check
You betcha - especially if the examiner asks you to actually FLY the aeroplane by hand with no flight director or any other glass cockpit goodies and won't let you use the autopilot. That's REAL Mayday stuff. Manually flying big jets is positively dangerous and one European operator using 737's advise in their Ops manual that manual flying is only to be carried out under the most exceptional circumstances. And even then the flight director MUST be used. Lordy Almighty I make the sign of the Cross when that autopilot is switched off..
