help me save the control tower on my airfield as well as many more. maybe one near your neck of the woods.

Weather (wait to Clear)
What is it?
Airspace in the shape of a racetrack used by ATC, for traffic delay of arrivals, over a given fix on NAVAID’S, either intersection of airways or intersection.
DME DIST FROM FIX
ON LOCALIZER COURSE
Speeds (propeller a\c is 175 kn then as depicted on approach plates under a\c category)
200 kn-(SFC – 6000)
230 kn (6001-14000)(210 when published)
265 kn (14001 – ∝ )
1 minute below 14,000
1.5 minutes above 14,000
Turns: a standard turn is to the right. If turns were to the left, it would be stated in the clearance. These are referred to as non standard turns.
Bank: all turns are to Standard rate. Never to exceed 25°.
Recommended Entries: explain and show examples of each entry
Direct: if the aircraft nose after reaching the fix, is on the fixed arc portion.
Teardrop: if the aircraft’s nose after reaching the fix, is on the holding side of the track.
Parallel: if the aircraft nose after reaching the fix, on the non holding side of the track.
- Cardinal direction from the holding fix.
- Fix name
- Course (radial, airway or route)
- Leg length in miles if DME or RNAV is used
- Direction of turns (omitted is standard turns are to be used)
- Expect further clearance (EFC)
The simplest hold clearance is “ hold as published”
Example of hold Clearance: “N8724M cleared to the “ABC” VOR; hold East on the 90 radial, EFC 30 min past the hr.”
- If you arrive at your clearance limit before clearance beyond the fix, ATC expects to maintain the last assigned altitude and begin holding in accordance to depicted pattern.
- If a pattern is not shown, hold standard turns on the course you approached the fix. Immediately request further clearance.
- ATC will issue clearance at least 5 minutes ETA to the fix if delays are expected.
- If a hold is published and controller does not issue a complete clearance, the pilot is expected to fly the hold as depicted.
- When a/c is 3 minutes or less from a clearance limit, and no clearance beyond the point has received, the pilot is expected to start a speed reduction to cross the fix at or below the maximum holding airspeed.
Holding pattern and its components:
A Holding and non-holding sides
B Inbound course
C Outbound course
E Abeam Point
Wind Effects on Holding Patterns:
In compliance with the holding pattern procedure given in AIM, the symmetrical racetrack pattern cannot be tracked when winds exist.
Pilots are expected to:
- Compensate for the effect of a known wind except when turning
- Adjust outbound timing to achieve a one minute inbound leg. (1.5 minutes above 14,000 feet)

we have a rule of thumb to calculate the standard Bank for a given speed.
so at any given speed lets say 120 knots. what would your standard rate bank angle be?
19 degrees would be your standard bank angle to establish and fly a standard rate turn.
If this information is available on the aircrafts manual the posted bank shall be used.
Steep Turns (Practical Lesson)
Objective: To control the A/C by reference to instruments while performing greater-than-normal bank attitudes
*Any turn greater than standard is considered steep. In IFR never exceed std. rate turns. Practicing steep turns will make reactions smooth, quick, and pilot more confident controlling A/C when encountering actual IMC.
– Va set power to 2,100RPM
- Set ALT, trim
- Clear area
- Pick HI and ALT, set Va
- Bank *SMOOTHLY with reference to AI
- As passing 30’ add 100 RPM (Vertical component of lift drops – extra RPM will compensate)
- Establish 45’ by AI
- *Scan ALT, VSI, AI, TC *increase scan
- *Trim as necessary (correct direction)
- Check HI and plan to roll out at ½ bank *(approx. 20’-25’)
- Start roll out *SMOOTH *AI (precession of the horizon bar)
- Remove extra RPM
- Re- trim
Regulatory (Class A, B, C, D, E, restricted and Prohibited)
Non Regulatory (Military Operating Areas, Warning Areas, Alert Areas, Control Firing Areas”CFR’s”)
Controlled Uncontrolled Special Use Other Airspace
Hierarchy of Overlapping Airspace
When overlapping exist most restrictive airspace applies Class A more restrictive than Class B. Class B more restrictive than Class C and so on.
