I get that this is a post about the basics of an airframe, however, I'm not a fan of 'settings' used for anything except helping newer pilots or pilots new to the airframes.
A flight leads settings are just that. Using 'settings' for climbing\rejoining wont allow someone to catch up if the flight lead is cruising level as an example. Complicated even more by fuel levels (weight), trim state and that we fly mixed aircraft/variants in flights.
Personally, I feel giving the other pilots my indicated air speed, altitude and rate of climb allows the pilots to adjust their aircraft to exceed those figures to catch up. It is truly universal. If they don't know how, then tell them 'settings'.
Example 1]
"Whats your settings, I can't catch up"
Settings told.
5minutes later.
"I still can't catch up."
"Roger, reducing throttle to 70%"
5minutes later
"I think i'm gaining."
2minutes later
"Are you with us yet, I'm nearly out of fuel?"
"Nearly - Oh that explains alot, I have a full tank!"
Example 2]
"I can't catch up"
"I'm at 200mph, rate of climb 2000 feet - angels 10."
"Roger, I'm doing 210mph, it's going to take some time."
"Roger that, slowing to 180mph."
5minutes later
"In formation, thanks for slowing."
"No worries, throttling upto 200mph."
Each to their own I guess - but for forming up - I use the dials to clearly communicate the information required. I resort to 'settings' for a new pilot/pilots new to the airframe.
When you are chasing something, or on an attack run, then 'settings' do come in handy.
"Dropping rads to fifty - pulling the tit!" is one of my favorites (Hurricane FB and Blenheim). I Still say fifty, even though I don't have the screen stuff - you can see halfway is halfway on either the radiator lever, the radiator indicator or the radiator cowls themselves (airframe dependant). The temperature gauges are crucial here. No point dropping the rads if you've climbed (slow airspeed) up to within a degree of popping your radiator.
Just my 2 pence, not to be taken as an arguement - again - using 'settings' is great for new pilots/pilots new to the airframes. However, once the training wheels are off - use the dials. You will start to learn the dials when you have the 'settings' set then say "I can't catch up - I'm only do 180mph" (climbing). Dials are the logical progression from 'settings' and reduce comms clutter.
Dave, it's all about the RPM on the blenheim - over 2400ish RPM and it's going to start to cook - regardless of pitch/boost. 2400 RPM will also cook it if your airspeed is too low to cool the engines.
- You wouldn't hold your car/bike/other at the redline of RPM while stationary for very long before the temperatures rise. However, on a race track / autobahn you can accelerate upto the redline in every gear and it 'should' stay within tolerances. Unless you are doing a 'burn-out' - which quite often leads to more than just the tires burning out. Airflow is important to take into consideration when using 'max rpms'.
