Again flawed reasoning. Nobody that is all alone in the pattern flies a
7 minute pattern.
Actually, to me a 7 minute pattern sounds reasonable IF a person runs a
1000 foot AGL pattern in a typical Cessna as follows in a touch and go
in a no wind situation. (numbers would be approximate based on my
experiences)
Climbout 1 1/2 minutes (climb to 800 AGL at 500 feet per minute)
Crosswind 1/4 minute (climb to 900 AGL)
Downwind (Climb to 1000 AGL, level off, pick up speed) 3/4 minute
Abeam the numbers (throttle back start descent) 1/2 minute
Base 1/4 minute
Final 3/4 minute
Touchdown to clearing the length of the runway and getting back to 800
AGL (assuming 4500 foot runway or so) 2 minutes.
The above adds up to 6 minutes. Add in a little wind, and the headwind
component would add time to the leg that is in the headwind (crosswind,
base or final).
Now throw in a 800 foot pattern, then maybe knock off a minute, but I
don't run 800 foot patterns that I have seen others do. All airports I
have been had 1000 TPA
Looking at my log book, the above would consistent for when I did 10
touch and goes in 1.3 hours.
