MPRTs Flashcards
What is the maximum exercise limit of g loading for an MPRT?
5g
How is the attitude, and therefore the speed, controlled in an MPRT?
AoB
AoB reduced = Nose pitches up and therefore the aircraft slows, and vice versa
What do you need to do with the aileron to keep the aircraft on the required parameters during an MPRT?
Bit of in to turn aileron
Relative airflow impinging on the lower wing creates a rolling moment in the opposite direction of the turn. Adverse yaw will then cause the nose to rise if left unchecked.
Name two of the most important safety points for flying MPRTs
Base height awareness - You will lose height rapidly. Remember you HASLLG calculations and be constantly base height aware. Declare heights throughout the descent.
Lookout - Rotate to look deep in to the turn and also below the aircraft to clear the airspace you are descending in to. 90% of your time should be spent on lookout.
What is the stabilised MPRT speed?
210 KIAS
What are the conditions of a stabilised MPRT?
Alpha - 16 units (artificial buffet throughout)
G - 5g
Attitude - Approx. 15 deg. ND WL
Speed - Approx. 210 KIAS
What is the key MPRT parameter to achieve and maintain first and foremost?
16 units AoA - Maintain the buffet
Then small attitude adjustments (AoB) to increase/decrease speed and therefore G whilst maintaining the buffet.
How do you enter an MPRT from the stabilised speed (210 KIAS)?
Lookout - Dip a wing to assist looking below the aircraft (TCAS below from HASLLG)
Roll to 90 deg. AoB, apply MAX power (‘picture, power’)
Pull to 4.5g, squeeze to 5g or the artificial buffet.
Allow nose to drop to approx. 15 deg. ND.
Keep the artificial buffet/16 units and adjust attitude using AoB to maintain 5g.
Enter maintenance work cycle.
How do you enter an MPRT from below the stabilised speed?
Lookout, including below (TCAS below from HASLLG)
Roll to 90 deg. AoB - rudder to balance + MAX power and pull to artificial buffet
Allow the nose to drop to approx. 20-25 deg. ND. Allow aircraft to accelerate while maintaining artificial buffet/16 units.
Speed and g will increase - increase BP to maintain the buffet.
Just before achieving 5g adjust the attitude to the stabilised attitude - approx. 15 deg. ND.
Maintain the turn and monitor height.
How do you enter an MPRT from above the stabilised speed (240 KIAS and above)?
Lookout, including below (TCAS below from HASLLG)
Roll to about 80 deg. AoB, apply MAX power using rudder to balance.
Pull to 4.5g, squeeze to 5g (enter slight 2-3 deg. climb to reduce aircraft speed).
At about 220 KIAS, overbank to lower the nose to normal MPRT attitude.
What is the workcycle to maintain an MPRT?
Lookout - Attitude - Alpha - g - Altimeter - Ball
Lookout between each
How do you exit an MPRT?
Relax the backpressure to unload before rolling (note +4.7g rolling g limit).
Pitch to S&L or climbing attitude as req.
Set power as req. for the next phase of flight.
FP - DW - TCAS (SA regain)
