AE & RHS Aircraft Range Formulas (additional unit conversion data)

General: These formulas are both a function of aviation principles (rules of thumb) and AE code. The latter refers to differences imposed by the type of aircraft in code. A different issue is the limits imposed by code. Code only allows for normal range, extended range, and transfer range. But in reality, almost every aircraft has four ranges: range with maximum load; range with normal load; range with reduced load and range with no load. So the modder must decide which three of these to use? Sometimes the design of the aircraft decides. Thus, many Japanese Navy aircraft have maximum load equal to normal load. Most aircraft in AE do not carry maximum load, only normal load and reduced load. But one may alternatively use maximum load range and normal load range (treated as normal load range and reduced load range). The other thing is units: you may use statute miles or nautical miles, but you MUST be consistent – the same for all types in your database. It matters that all aircraft be defined to a single standard, rendering in game performance relatively accurate.

To convert nautical miles to statute miles, multiply times 1.150779 (or 1.151).
To convert statute miles to nautical miles, multiply times 0.868976 (or 0.869).
To convert nautical miles to kilometers, multiply times 0.5599568 (or 0.560).
To convert kilometers to nautical miles, multiply times 1.852.

Transport Planes (other than flying boats):
Transfer Range = 80% of real life Ferry Range (endurance * cruising speed / 60)
Extended Range = 50% of Transfer Range
Normal Range = 70% of Extended Range

Special cases for transport types for which good bomber statistics are available:
Ceiling: 96% of bomber ceiling for a transport variant of a bomber.
Maximum Speed: 101% of bomber maximum speed for a transport variant of a bomber.
Rate of Clime: 100.5% of bomber ROC for a transport variant of a bomber.
Maximum Load: 114% of bomber maximum speed for a transport variant of a bomber.
Normal Load: 120% of bomber normal load for a transport variant of a bomber.
Empty Equipped Weight: 98% of bomber EEW for a transport variant of a bomber.
Normal Load: 114% of bomber normal load for a transport variant of a bomber OR 220 pounds times the number of passengers. Use 114% if mainly a cargo plane; use 220 x passengers otherwise.

AE & RHS Aircraft Range Formulas, Page 2

Bombers:
Transfer Range = Ferry Range (endurance * cruising speed / 60)
Extended Range = 57% of Transfer Range (48% if very heavy load; 61% if very light load)
Normal Range = 48% of Transfer Range (41% if very heavy load)

Special Cases for Bombers with large drag (> 67 pounds) External Weapons:
Extended Range = 36% of Transfer Range
Normal Range = 29% of Transfer Range
Special Cases for Bombers with External Drop Tanks: (not normal with external load weapons)

Drop Tank Transfer Range ((endurance + drop tank endurance) * cruising speed / 60)
Drop Tank Extended Range = Extended Range plus 33% of Drop Tank Added Range
Drop Tank Normal Range = Normal Range plus 26% of Drop Tank Added Range

Special Cases for Bombers with Internal Drop Tanks (aka ferry tanks or auxiliary tanks):
Drop Tank Transfer Range ((endurance + drop tank endurance) * cruising speed / 60)
Drop Tank Extended Range = 57% of Drop Tank Transfer Range
Drop Tank Normal Range = 48% of Drop Tank Transfer Range

Special Case for Bombers with Very Light Load:

Fighters (without bombs, internal bombs or total bombs < 68 pounds):
Transfer Range = Ferry Range (endurance * cruising speed / 60)
Extended Range = 40% of Transfer Range
Normal Range = 33% of Transfer Range

Special Cases for Fighters with large drag (> 67 pounds) External Weapons:
Extended Range = 26% of Transfer Range
Normal Range = 20% of Transfer Range

AE & RHS Aircraft Range Formulas, Page 3

Special Cases for Fighters with External Drop Tanks: (not normal with external load weapons)
Drop Tank Transfer Range ((endurance + drop tank endurance) * cruising speed / 60)
Drop Tank Extended Range = Drop Tank Extended Range - 500
Drop Tank Normal Range = 70% of Drop Tank Extended Range

Special Cases for Fighter Bombers with large drag (> 67 pounds) External Weapons:
Extended Range = 33% of Transfer Range
Normal Range = 26% of Transfer Range

Special Cases for Strafe Fighters (e.g. IL-2m3):
Transfer Range = Ferry Range (endurance * cruising speed / 60)
Extended Range = 75% of Transfer Range
Normal Range = 55% of Transfer Range


Reconnaissance Aircraft:
Transfer Range = Ferry Range (endurance * cruising speed / 60)
Extended Range = 90% of Transfer Range
Normal Range = 80% of Transfer Range

Special Cases for Recon Aircraft with External Drop Tanks:
Transfer Range = Ferry Range (endurance * cruising speed / 60)
Drop Tank Extended Range = Extended Range plus 33% of Drop Tank Added Range
Drop Tank Normal Range = Normal Range plus 26% of Drop Tank Added Range

AE & RHS Aircraft Range Formulas, Page 3

Special Cases for Kamakaze Aircraft (Only in Downfall Scenarios with Kamakaze = Yes):
Transfer Range = Ferry Range (endurance * cruising speed / 60)
Extended Range = Extended Range plus 67% of Transfer Range
Normal Range = 55% of Transfer Range

AE & RHS Aircraft Range Formulas, Page 4

Flying Boats (Patrol):
Transfer Range = Ferry Range (endurance * cruising speed / 60)
Extended Range = 75% of Transfer Range
Normal Range = 67% of Transfer Range

Flying Boats (Transport):
Transfer Range = Ferry Range (endurance * cruising speed / 60)
Extended Range = 50% of Transfer Range
Normal Range = 70% of Extended Range

Special Cases for Flying Boats with large drag (> 67 pounds) External Weapons:
Transfer Range = Ferry Range (endurance * cruising speed / 60)
Extended Range = 66% of Transfer Range
Normal Range = 57% of Transfer Range

Flying Boats (Observation):
Transfer Range = Ferry Range (endurance * cruising speed / 60)
Recon (no bomb) Extended Range = 90% of Transfer Range
Patrol (with bombs) Normal Range = 57% of Transfer Range

Blimps:
Transfer Range = Ferry Range (endurance * cruising speed / 60)
Extended Range = 90% of Transfer Range
Normal Range = 80% of Transfer Range
Notes: Use wing loading = 0 and Power Loading = lift / power in maneuverability calculation.
