Mach tuck is an aerodynamic effect whereby the nose of an aircraft tends to pitch downward as the airflow around the wing reaches supersonic speeds. This diving tendency is also known as tuck under. The aircraft will first experience this effect at significantly below Mach 1.
What are the 3 different types of holding patterns?

What is a Mach trim?
Mach trim takes nose of aircraft up, while alpha trim brings nose down. Alpha trim prevents low speed stall, Mach trim prevents high speed stall.
What is aircraft ceiling?
With respect to aircraft performance, a ceiling is the maximum density altitude an aircraft can reach under a set of conditions, as determined by its flight envelope.
What is M crit?
In aerodynamics, the critical Mach Number (Mcr or Mcrit) of an aircraft is the lowest Mach number at which the airflow over any part of the aircraft reaches the speed of sound.
What is minimum holding altitude?
MINIMUM HOLDING ALTITUDE- The lowest altitude prescribed for a holding pattern which assures navigational signal coverage, communications, and meets obstacle clearance requirements.
What is included in a holding clearance for an unpublished hold?
As a quick review, complete holding instructions will include the direction of the hold from the fix; the name of the fix; the radial, course or airway on which you’ll hold inbound, leg length if it’s in miles; and direction of turns if they’re to the left.
What is a timed approach from a holding fix?
When making a timed approach from a holding fix, the pilot should adjust the holding pattern to leave the final approach fix inbound at the assigned time. The first step in a hold is to fly to the fix. From this point you enter the holding procedure.

How is WCA aviation calculated?
The Wind Correction Angle can be measured with a protractor. The WCA can be calculated. The green arrow is the ‘true’ crosswind component: WS*sin(AWA). This equals TAS*sin(WCA), so, to find WCA we have to take the inverse sine.
How do you calculate aircraft wind drift?
Finding Drift If we divide wind speed by the aircrafts TAS in nm per minute, we get maximum drift. If we then apply the clock system, based on track, we can learn what fraction of maximum drift we can expect.
