State the purpose of a Mu-Meter (Or CFME) |
To measure and record the friction (Mu) on all types of surfaces in all weather condition. This will enable an accurate assessment of the breaking action a pilot may experience, especially on a runway |
|
|
When are Mu-Meter runs conducted? |
If any doubt exists about the surface conditions When surface states change due to moderate or heavy precipitation (with a depth less than 3mm) When an accident occurs or when aircraft engage the arrester gear As a check of deterioration on aerodrome surfaces |
|
|
How are Mu-Meter rus conducted? |
Runs should be made at 40mph +/-3mph Accuracy is speed dependant, especially on wet surfaces where low speeds may not detect aquaplaning Between 2 and 10m either side of the centreline Large rubber deposits should be subject to seperate runs Mark events and slow down if transiting over arrester cables |
|
|
State the purpose of recording Mu-Meter data |
A printout can be produced if required Information can be stored digitally All Mu-Meter results are to be passed to the ATCO IC |
|
|
State the information shown on a Mu-Meter printout |
Date Time Runway Aerodrome Mu Meter range and average |
|
|
What precautions must be taken when towing a Mu Meter? |
Never reverse while the Mu Meter is attached Never exceed the speed limit Never carry additional weight on the Mu Meter trailer |
