Title: Time To Launch
Post by: Mongoose on November 25, 2015, 02:58:19 PM
Can anyone point me to some source material that would tell you how long it would take to launch a particular aircraft? In other words how long it would take from the time I climbed into my Spitfire Mk. VIII to the time I was able to take off.

As long as it takes for oil temp to come up to around 40C. A few minutes.

:airplane: Get the "CH's" temps in bottom of green as well as what Columbo pointed out

Ok, but how long would that normally take on a standard issue spring day at sea level? In your experience, how long would it take you from the time you enter the plane to the time you lift?

The longest part of the process would be waiting for temps to come up in the engine, assuming your not including the pre-flight check of the airplane.

Most units on both side used alarm-units, planes already wamed-up by ground-crews, ready for interceptions.

:airplane: In that case, with the engine warmed to normal outside air temps, I would guess about 4 minutes to warm up oil and cylinders and you could be doing pre-takeoff check list during this time, pull the chocks, 2 minutes to taxi to active runway and talk to the controllers, then blast off into the blue. I would guess about 6 to 7 minutes to full throttle for takeoff, but that is just a guess!

In the Battle Of Britain the RAF had three readiness states: 'Available' (20 minutes) - 'at readiness' (5 minutes) and 'stand-by' (2 minutes).
At 'stand-by' they had only two minutes to get airborne. Ground crew would start the engines as the pilots ran to their aircraft. When they got there the pilots would just jump in and go.

This and the previous post from Earl give me the time frames I was looking for. Thank you gentlemen.
